The <strong>Canon G7 X Mark III<\/strong> is a very strong option for photographers who want a bright 24-100mm lens, good image quality, Manual mode, 4K video, and a compact body. The <strong>OM System Tough TG-7<\/strong> is the easiest and toughest option, especially for beginners, snorkelers, travel divers, and close-up shooters who want a rugged waterproof camera.<\/p>\n<p>This guide compares all three cameras for underwater photography, including image quality, video, macro performance, manual control, durability, housing options, accessories, and real dive use.<\/p>\n<div style=\"border: 1px solid #d9e6ef; padding: 18px; border-radius: 8px; background: #f5fbff; margin: 24px 0;\">\n<h2 style=\"margin-top: 0;\">Quick Verdict<\/h2>\n<ul>\n<li><strong>Choose the Sony RX100 VII<\/strong> if you want the best overall performance, strongest autofocus, long zoom range, 4K video, and serious compact-camera image quality.<\/li>\n<li><strong>Choose the Canon G7 X Mark III<\/strong> if you want strong image quality, a bright 24-100mm lens, Manual mode, 4K video, and a compact setup that works well for photos and casual video.<\/li>\n<li><strong>Choose the OM System Tough TG-7<\/strong> if you want the toughest, simplest, most beginner-friendly underwater camera for snorkeling, travel, shallow water, macro, and rough conditions.<\/li>\n<\/ul>\n<\/div>\n<h2 class=\"wp-block-heading\">Updated Buying Note for 2026<\/h2>\n<p>The Canon G7 X Mark III, OM System Tough TG-7, and Sony RX100 VII are still very relevant compact cameras for underwater photography in 2026. They are popular because they stay small, work with underwater housings, support wet lenses and lighting, and give divers a more capable setup than a phone or basic action camera.<\/p>\n<p>The important point is that these are newer and more relevant models than the older Canon G7X II, Olympus TG-5, and Sony RX100 V comparison. The TG-7 replaces the older TG-5 in this guide, and the RX100 VII replaces the RX100 V. The Canon G7 X Mark III also gives important upgrades over the G7 X Mark II, especially 4K video, Full HD 120fps, a stacked 1-inch sensor, and a microphone input.<\/p>\n<p>The best camera is not only the one with the strongest spec sheet. The better question is: which camera fits your dive style, budget, housing options, and the type of photos or videos you want to create?<\/p>\n<h2 class=\"wp-block-heading\">Best Camera by Use Case<\/h2>\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<thead>\n<tr>\n<th>Use Case<\/th>\n<th>Best Choice<\/th>\n<th>Why<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Best overall compact camera<\/td>\n<td>Sony RX100 VII<\/td>\n<td>Strong 1-inch sensor, excellent autofocus, long 24-200mm zoom, 4K video, and advanced features.<\/td>\n<\/tr>\n<tr>\n<td>Best autofocus<\/td>\n<td>Sony RX100 VII<\/td>\n<td>Fast hybrid AF, Real-time Tracking, and strong subject tracking make it the most advanced focusing camera here.<\/td>\n<\/tr>\n<tr>\n<td>Best underwater video<\/td>\n<td>Sony RX100 VII<\/td>\n<td>4K HDR, strong autofocus, good stabilization options, and advanced video tools.<\/td>\n<\/tr>\n<tr>\n<td>Best simple rugged camera<\/td>\n<td>OM System Tough TG-7<\/td>\n<td>Waterproof, shockproof, freezeproof, dustproof, and easy to travel with.<\/td>\n<\/tr>\n<tr>\n<td>Best beginner option<\/td>\n<td>OM System Tough TG-7<\/td>\n<td>Simple underwater modes, rugged body, strong macro features, and less setup complexity.<\/td>\n<\/tr>\n<tr>\n<td>Best built-in macro ease<\/td>\n<td>OM System Tough TG-7<\/td>\n<td>Excellent close-focusing features and a 1cm focusing distance make it very easy for small subjects.<\/td>\n<\/tr>\n<tr>\n<td>Best balanced photo\/video compact<\/td>\n<td>Canon G7 X Mark III<\/td>\n<td>Bright lens, 1-inch stacked sensor, 4K video, Manual mode, and useful 24-100mm range.<\/td>\n<\/tr>\n<tr>\n<td>Best for manual exposure and strobes<\/td>\n<td>Sony RX100 VII or Canon G7 X Mark III<\/td>\n<td>Both offer full Manual mode, which helps when controlling underwater strobes.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<h2 class=\"wp-block-heading\">Quick Specs Comparison<\/h2>\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>Sony RX100 VII<\/th>\n<th>Canon G7 X Mark III<\/th>\n<th>OM System Tough TG-7<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Sensor<\/td>\n<td>20.1MP 1.0-type stacked Exmor RS CMOS<\/td>\n<td>20.1MP 1.0-type stacked CMOS<\/td>\n<td>12MP 1\/2.33-inch CMOS<\/td>\n<\/tr>\n<tr>\n<td>Lens<\/td>\n<td>24-200mm f\/2.8-4.5<\/td>\n<td>24-100mm f\/1.8-2.8<\/td>\n<td>25-100mm f\/2.0-4.9<\/td>\n<\/tr>\n<tr>\n<td>Maximum Video Quality<\/td>\n<td>4K HDR<\/td>\n<td>4K<\/td>\n<td>4K<\/td>\n<\/tr>\n<tr>\n<td>Slow Motion<\/td>\n<td>Up to 960\/1000fps HFR<\/td>\n<td>Full HD 120fps<\/td>\n<td>Full HD 120fps, HD 240fps, SD 480fps<\/td>\n<\/tr>\n<tr>\n<td>Continuous Shooting<\/td>\n<td>Up to 20fps<\/td>\n<td>Up to 20fps, plus 30fps RAW Burst<\/td>\n<td>Up to 20fps electronic shutter<\/td>\n<\/tr>\n<tr>\n<td>RAW<\/td>\n<td>Yes<\/td>\n<td>Yes<\/td>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<td>Manual Mode<\/td>\n<td>Yes<\/td>\n<td>Yes<\/td>\n<td>No full Manual mode<\/td>\n<\/tr>\n<tr>\n<td>Waterproof Without Housing<\/td>\n<td>No<\/td>\n<td>No<\/td>\n<td>Yes, down to 50 ft \/ 15 m<\/td>\n<\/tr>\n<tr>\n<td>Best Strength<\/td>\n<td>Autofocus, zoom, video, image quality<\/td>\n<td>Bright lens, Manual mode, compact photo\/video use<\/td>\n<td>Rugged build, macro, ease of use, travel<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p><strong>Official spec references:<\/strong> Sony lists the RX100 VII with a 20.1MP 1.0-type stacked sensor, 24-200mm lens, 4K HDR video, Real-time Tracking, and high-speed video.

It records detailed 4K video, supports HDR HLG, has strong autofocus during video, and includes advanced tools such as Real-time Tracking, S-Log profiles, a microphone input, and high-frame-rate slow motion. For underwater video, this helps when filming fish, divers, reef movement, bubbles, and fast behavior moments.<\/p>\n<p>The <strong>Canon G7 X Mark III<\/strong> is also much stronger for video than the older G7 X Mark II. It records 4K, offers Full HD 120fps, includes a microphone input, and works well for casual underwater video, travel clips, social media, and hybrid photo\/video use. Its autofocus is not as advanced as the Sony RX100 VII, especially for fast-moving subjects.<\/p>\n<p>The <strong>OM System Tough TG-7<\/strong> records 4K and is very easy to use underwater. It is not as advanced as the Sony for autofocus or video control, but it is excellent for simple dive clips, snorkeling footage, travel videos, and close-up underwater scenes.<\/p>\n<h3 class=\"wp-block-heading\">A quick note on 4K underwater video<\/h3>\n<p>4K gives you more flexibility in editing. You can crop, reframe, or export in 1080p while keeping good detail. This helps when a fish moves quickly, a diver drifts out of frame, or your composition needs small corrections.<\/p>\n<p>At the same time, 4K does not automatically create better underwater footage. Lighting, white balance, stability, lens choice, visibility, and exposure often matter more than resolution. A clean 1080p clip with good light and color can look better than shaky 4K footage with weak color.<\/p>\n<h2 class=\"wp-block-heading\">Lens and Macro Performance<\/h2>\n<p>The lens range matters a lot underwater because it affects framing, working distance, wet lens compatibility, and how well the camera handles macro or wide-angle scenes.<\/p>\n<p><figure style=\"width: 406px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/www.backscatter.com\/ITEM_IMAGES\/in-ucl-90_1.jpg?resizeid=6&amp;resizeh=600&amp;resizew=600\" width=\"406\" height=\"406\" \/><figcaption class=\"wp-caption-text\"><a href=\"https:\/\/www.housingcamera.com\/inon-4562121438583-macro-lens.html?___store=default_cad&amp;srsltid=AfmBOopT7Tzj29rgtNQn400ckDqZUufjCTlw1H_LTk1B5CXJHOXvT8fc&amp;utm_\"><span style=\"color: #0000ff;\"><strong>UCL-90 M67 Underwater Close-up Lens<\/strong><\/span><\/a><\/figcaption><\/figure><\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Sony RX100 VII:<\/strong> 24-200mm equivalent lens<\/li>\n<li><strong>Canon G7 X Mark III:<\/strong> 24-100mm equivalent lens<\/li>\n<li><strong>OM System Tough TG-7:<\/strong> 25-100mm equivalent lens<\/li>\n<\/ul>\n<p>The <strong>Sony RX100 VII<\/strong> has the longest lens range here. The 24-200mm zoom is useful for travel, topside photography, fish portraits, and tighter framing. Underwater, the longer zoom can help for certain close-up subjects, but wet wide-angle compatibility and housing port choices matter more when building a full system.<\/p>\n<p>The <strong>Canon G7 X Mark III<\/strong> has a very useful 24-100mm lens with a bright f\/1.8-2.8 aperture range. It gives good flexibility for underwater photography and can work well with macro diopters and wet lenses when paired with the right housing and accessories.<\/p>\n<p>The <strong>OM System Tough TG-7<\/strong> is the easiest macro camera in this group. Its close-focusing ability and microscope-style macro features make it very beginner-friendly for small subjects. It is a strong option for nudibranchs, coral details, textures, tiny reef life, tide pools, and shallow-water close-ups.<\/p>\n<h3 class=\"wp-block-heading\">Simple lens takeaway<\/h3>\n<ul class=\"wp-block-list\">\n<li><strong>Sony RX100 VII:<\/strong> best zoom range and strongest advanced compact performance.<\/li>\n<li><strong>Canon G7 X Mark III:<\/strong> bright 24-100mm lens, good balance for photo and video.<\/li>\n<li><strong>OM System Tough TG-7:<\/strong> easiest close-up and macro shooting, especially for beginners.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\">Image Quality Underwater<\/h2>\n<p>Image quality underwater comes from more than megapixels. Sensor size, lens sharpness, autofocus, dynamic range, lighting, water clarity, and color control all matter.<\/p>\n<p>The <strong>Sony RX100 VII<\/strong> gives the strongest overall image quality in this comparison. Its 1-inch stacked sensor, advanced autofocus, strong processor, and long zoom range make it the most capable compact camera here for serious underwater shooters.<\/p>\n<p>The <strong>Canon G7 X Mark III<\/strong> is close behind for still photography. It also uses a 1-inch stacked sensor and has a bright lens. It can produce excellent underwater images, especially when paired with a good housing, quality wet lenses, and proper lighting.<\/p>\n<p>The <strong>OM System Tough TG-7<\/strong> has a smaller sensor, so it cannot match the Sony or Canon for pure image quality, low-light performance, or dynamic range. Still, it can produce very good underwater photos when used well, and its rugged body and macro features make it extremely practical.<\/p>\n<h3 class=\"wp-block-heading\">Image quality ranking<\/h3>\n<ol class=\"wp-block-list\">\n<li><strong>Sony RX100 VII:<\/strong> strongest image quality overall.<\/li>\n<li><strong>Canon G7 X Mark III:<\/strong> very strong image quality with a bright lens and 1-inch sensor.<\/li>\n<li><strong>OM System Tough TG-7:<\/strong> good image quality for a rugged compact camera, especially for macro and travel use.<br \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-18153\" src=\"https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-ekamelev-920157-300x300.jpg\" alt=\"\" width=\"250\" height=\"250\" srcset=\"https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-ekamelev-920157-300x300.jpg 300w, https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-ekamelev-920157-16x16.jpg 16w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-18154\" src=\"https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-belle-co-99483-847393-300x300.jpg\" alt=\"\" width=\"250\" height=\"250\" srcset=\"https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-belle-co-99483-847393-300x300.jpg 300w, https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-belle-co-99483-847393-16x16.jpg 16w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-18155\" src=\"https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-francesco-ungaro-3390587-300x300.jpg\" alt=\"\" width=\"250\" height=\"250\" srcset=\"https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-francesco-ungaro-3390587-300x300.jpg 300w, https:\/\/www.housingcamera.com\/blog\/wp-content\/uploads\/2026\/05\/pexels-francesco-ungaro-3390587-16x16.jpg 16w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><\/li>\n<\/ol>\n<h2 class=\"wp-block-heading\">Manual Mode and Strobe Control<\/h2>\n<p>Manual mode is one of the most important differences for underwater photography.<\/p>\n<p>The <strong>Sony RX100 VII<\/strong> and <strong>Canon G7 X Mark III<\/strong> both offer full Manual mode. This makes them better choices for divers who want to control strobes, background exposure, shutter speed, aperture, and ISO more precisely.<\/p>\n<p>The <strong>OM System Tough TG-7<\/strong> does not offer the same full manual exposure control. It is designed more around automatic modes, aperture priority, underwater modes, and easy close-up shooting. Many beginners will prefer this because it makes the camera simpler underwater.<\/p>\n<p>With strobes, Manual mode gives you more control over the balance between ambient light and artificial light. You can darken the water, freeze movement, reduce backscatter, and control how bright the subject appears in the frame.<\/p>\n<p>For photographers who want to grow into strobes, wet lenses, and more advanced lighting, the Sony RX100 VII and Canon G7 X Mark III give more room to improve. For divers who want simple shooting, travel use, snorkeling, and macro without a steep learning curve, the TG-7 is easier to trust.<\/p>\n<p><figure style=\"width: 305px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/www.housingcamera.com\/media\/catalog\/product\/cache\/8b71aa79053ea777eb0e99418b0c5dd1\/b\/s\/bs-mf-3_01.jpg\" width=\"305\" height=\"305\" \/><figcaption class=\"wp-caption-text\"><a href=\"https:\/\/www.housingcamera.com\/backscatter-mini-flash-3-underwater-strobe-mf-3.html\"><strong><span style=\"color: #0000ff;\">Mini Flash MF-3 Strobe<\/span><\/strong><\/a><\/figcaption><\/figure><\/p>\n<h2 class=\"wp-block-heading\">Robustness and Travel Use<\/h2>\n<p>The <strong>OM System Tough TG-7<\/strong> clearly stands out for rough travel and simple use.<\/p>\n<p>It is waterproof to 50 ft \/ 15 m, shockproof, crushproof, freezeproof, and dustproof. This makes it appealing for snorkelers, freedivers, beach trips, kayaking, pool use, tide pools, shallow reefs, and travel days when you do not want to carry a full underwater housing system.<\/p>\n<p>The <strong>Sony RX100 VII<\/strong> and <strong>Canon G7 X Mark III<\/strong> are compact, but they are not waterproof cameras. For underwater use, they need a proper underwater housing.<\/p>\n<p>For scuba diving, even the TG-7 is safer inside a housing. Saltwater, pressure, repeated use, sand, and accidental knocks can create risk over time. A proper housing gives better protection, improves handling underwater, and often allows better accessory support.<\/p>\n<h2 class=\"wp-block-heading\">Housing Options<\/h2>\n<p>A camera body is only one part of an underwater photography system. Housing support matters because it affects safety, lens options, strobe connections, ergonomics, durability, and long-term upgrade potential.<\/p>\n<h3 class=\"wp-block-heading\">Canon G7 X Mark III housing options<\/h3>\n<p>The Canon G7 X Mark III also has good underwater housing support.

but each one fits a different type of shooter.<\/p>\n<h3 class=\"wp-block-heading\">Choose the Sony RX100 VII if:<\/h3>\n<ul class=\"wp-block-list\">\n<li>You want the strongest overall compact camera in this comparison.<\/li>\n<li>You care about fast autofocus and subject tracking.<\/li>\n<li>You want strong 4K video and advanced video features.<\/li>\n<li>You want the longest built-in zoom range.<\/li>\n<li>You plan to build a more serious compact underwater system.<\/li>\n<li>You are comfortable using a proper housing and accessories.<\/li>\n<\/ul>\n<h3 class=\"wp-block-heading\">Choose the Canon G7 X Mark III if:<\/h3>\n<ul class=\"wp-block-list\">\n<li>You want strong image quality from a 1-inch sensor.<\/li>\n<li>You want a bright 24-100mm lens.<\/li>\n<li>You want full Manual mode.<\/li>\n<li>You want 4K video in a small compact body.<\/li>\n<li>You shoot photos first, with some video on the side.<\/li>\n<li>You want a balanced compact camera that is easier to handle than a larger mirrorless setup.<\/li>\n<\/ul>\n<h3 class=\"wp-block-heading\">Choose the OM System Tough TG-7 if:<\/h3>\n<ul class=\"wp-block-list\">\n<li>You want the easiest camera to travel with.<\/li>\n<li>You want a rugged camera that can handle water, sand, bumps, and rough use.<\/li>\n<li>You are a beginner or casual underwater shooter.<\/li>\n<li>You want simple underwater modes.<\/li>\n<li>You shoot snorkeling, shallow water, tide pools, travel, or close-up subjects.<\/li>\n<li>You want strong macro features without building a complicated system.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\">FAQs<\/h2>\n<h3 class=\"wp-block-heading\">Is the TG-7 better than the TG-5?<\/h3>\n<p>The TG-7 is the newer model and is the more relevant camera to discuss in a current buying guide. It keeps the rugged design, strong macro ability, 4K video, RAW capture, and underwater-friendly features that made the Tough series popular. It also adds modern updates such as USB-C and improved workflow features.<\/p>\n<h3 class=\"wp-block-heading\">Is the Sony RX100 VII better than the Sony RX100 V underwater?<\/h3>\n<p>The Sony RX100 VII is the newer and more advanced camera. It has a longer 24-200mm lens, stronger autofocus, Real-time Tracking, 4K HDR video, and more advanced video features. The RX100 V can still be useful if you already own it, but the RX100 VII is the better match for a current comparison.<\/p>\n<h3 class=\"wp-block-heading\">Is the Canon G7 X Mark III better than the Canon G7 X Mark II?<\/h3>\n<p>Yes, the Canon G7 X Mark III is the newer and more relevant model. It adds 4K video, Full HD 120fps, a stacked 1-inch sensor, a newer processor, and a microphone input. The G7 X Mark II is still capable for photos, but the G7 X Mark III fits better in a current underwater compact camera guide.<\/p>\n<h3 class=\"wp-block-heading\">Which camera is best for underwater video?<\/h3>\n<p>The Sony RX100 VII is the strongest video option in this comparison because it offers 4K HDR, strong autofocus, Real-time Tracking, high-frame-rate options, and more advanced video tools.<\/p>\n<h3 class=\"wp-block-heading\">Which camera is best for beginner underwater photographers?<\/h3>\n<p>The OM System Tough TG-7 is usually the easiest beginner option because it is rugged, waterproof, compact, and has useful underwater shooting modes. It is also very strong for close-up and macro subjects.<\/p>\n<h3 class=\"wp-block-heading\">Do I need a housing for the OM System Tough TG-7?<\/h3>\n<p>For snorkeling and shallow-water use, the TG-7 can be used without a housing down to 50 ft \/ 15 m. For scuba diving, repeated saltwater use, or deeper dives, a proper housing is safer and gives better handling underwater.<\/p>\n<h3 class=\"wp-block-heading\">Which camera is best for macro photography?<\/h3>\n<p>The OM System Tough TG-7 is the easiest option for macro because of its close-focusing features and simple underwater modes. The Canon G7 X Mark III is also strong for macro when paired with the right housing and diopter. The Sony RX100 VII can produce excellent close-up images, but wet lens and port compatibility should be checked carefully because of its longer zoom range.<\/p>\n<h3 class=\"wp-block-heading\">Which camera has the best image quality?<\/h3>\n<p>The Sony RX100 VII has the strongest overall image quality in this comparison. The Canon G7 X Mark III is also very strong thanks to its 1-inch stacked sensor and bright lens. The TG-7 is good for a rugged camera, but its smaller sensor limits image quality compared with the Sony and Canon.<\/p>\n<h3 class=\"wp-block-heading\">What matters more: the camera or the underwater housing?<\/h3>\n<p>Both matter. The camera affects image quality, autofocus, video, and controls. The housing affects safety, handling, lens compatibility, strobe use, and long-term system growth. A good housing and lighting setup can make a major difference underwater.<\/p>\n<h2 class=\"wp-block-heading\">Final Recommendation<\/h2>\n<p>The best underwater compact camera in this comparison depends on your shooting style.<\/p>\n<p>Choose the <strong>Sony RX100 VII<\/strong> if you care most about image quality, autofocus, 4K video, long zoom range, and advanced compact-camera performance. It is the strongest overall camera here and gives the most serious compact setup for underwater photography and video.<\/p>\n<p>Choose the <strong>Canon G7 X Mark III<\/strong> if you want strong image quality, a bright 24-100mm lens, Manual mode, 4K video, and a compact setup that works well for both photos and video. It is a practical middle choice for divers who want more control than the TG-7 without moving into a larger camera system.<\/p>\n<p>Choose the <strong>OM System Tough TG-7<\/strong> if you want the toughest and simplest option. It is the easiest camera to travel with, the safest choice for rough conditions, and one of the best beginner-friendly underwater compact cameras for macro, snorkeling, and shallow-water use.<\/p>\n<p>For most divers who want the highest compact-camera performance, the Sony RX100 VII is the strongest choice. For a balanced photo and video setup, the Canon G7 X Mark III is very practical. For beginners, snorkelers, travel divers, and macro-focused casual shooters, the OM System Tough TG-7 is the easiest camera to trust.<\/p>\n<p>The best choice is the camera that matches the way you dive, travel, and shoot. A camera that fits your style will help you react faster underwater, enjoy the dive more, and come back with better photos and videos.<\/p>\n<section style=\"width: 100%; box-sizing: border-box; padding: 28px 18px; margin: 36px 0;\">\n<div style=\"max-width: 960px; margin: 0 auto; background: linear-gradient(135deg,#052b45,#0877a8); border-radius: 18px; padding: 3px; box-shadow: 0 18px 45px rgba(0,35,60,0.18); box-sizing: border-box;\">\n<div style=\"background: #041f33; border-radius: 15px; padding: 38px 44px 36px; font-family: Arial,Helvetica,sans-serif; color: #ffffff; box-sizing: border-box;\">\n<p style=\"display: inline-block; margin: 0 0 18px; padding: 8px 14px; background: rgba(255,255,255,0.12); border: 1px solid rgba(255,255,255,0.18); border-radius: 999px; color: #9be4ff; font-size: 13px; font-weight: 800; letter-spacing: 1.2px; text-transform: uppercase; line-height: 1;\">Mozaik Updates<\/p>\n<h2 style=\"margin: 0 0 14px; color: #ffffff; font-size: 34px; line-height: 1.15; font-weight: 800; max-width: 720px; font-family: Arial,Helvetica,sans-serif;\">Get underwater camera tips from Mozaik<\/h2>\n<p style=\"margin: 0 0 26px; color: #d8eef8; font-size: 17px; line-height: 1.55; max-width: 760px; font-family: Arial,Helvetica,sans-serif;\">Leave your email and we\u2019ll send you useful underwater photography tips, setup guides, product updates, and Mozaik news.<\/p>\n<form style=\"margin: 0!important; padding: 0!important; display: block!important;\" action=\"https:\/\/app.remarkety.com\/public\/subscribers\/createcontact\/\" method=\"post\"><input name=\"store_id\" type=\"hidden\" value=\"RmxBMDaY\" \/> <input name=\"form_id\" type=\"hidden\" value=\"Wx4AwXdr\" \/> <input name=\"tag_1\" type=\"hidden\" value=\"remarkety_newsletter\" \/><\/p>\n<div style=\"display: flex; gap: 14px; align-items: center; flex-wrap: wrap; max-width: 720px; margin: 0; padding: 0;\"><input style=\"flex: 1; min-width: 280px; max-width: 360px; height: 48px!important; min-height: 48px!important; padding: 0 16px!important; background: #ffffff!important; border: 1px solid #d8eef8!important; border-radius: 9px!important; color: #082033!important; font-size: 15px!important; line-height: 48px!important; outline: none!important; box-sizing: border-box!important; font-family: Arial,Helvetica,sans-serif!important; margin: 0!important;\" name=\"email\" required=\"\" type=\"email\" placeholder=\"Enter your email address\" \/> <button style=\"height: 48px!important; min-height: 48px!important; padding: 0 24px!important; background: #ffffff!important; color: #04314f!important; border: none!important; border-radius: 9px!important; font-size: 15px!important; font-weight: 800!important; cursor: pointer!important; white-space: nowrap!important; box-shadow: 0 6px 16px rgba(0,0,0,0.16)!important; display: inline-flex!important; align-items: center!important; justify-content: center!important; line-height: 1!important; margin: 0!important; font-family: Arial,Helvetica,sans-serif!important; box-sizing: border-box!important; appearance: none!important; -webkit-appearance: none!important; vertical-align: middle!important;\" type=\"submit\"> <span style=\"display: inline-block!important; line-height: 1!important; transform: translateY(-3px)!important; margin: 0!important; padding: 0!important;\">Keep me updated<\/span> <\/button><\/div>\n<\/form>\n<p style=\"margin: 18px 0 0; color: #a9d8eb; font-size: 14px; line-height: 1.45; font-family: Arial,Helvetica,sans-serif;\">Helpful updates from Mozaik, sent straight to your inbox.<\/p>\n<\/div>\n<\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Choosing between the Canon PowerShot G7 X Mark III, OM System Tough TG-7, and Sony RX100 VII depends on how you actually shoot underwater.
