Sony A7 IV Underwater Housing Options
Marelux Sony A7 IV MX-A7IV Underwater Housing
*Superb Ergonomics, Durable, Innovative Features*
Marelux is new to the underwater housing market, and the Marelux Sony A7 IV MX-A7IV Underwater Housing was one of their first releases. They introduced their first housings in the US back at the beginning of 2022. They shook up the established high-end housing market with their premium anodized aluminum designs priced more competitively than their counterparts.
Aside from giving their housings a premium feel, the anodized aluminum makes them extremely tough and scratch-resistant, which is something adventure-loving photographers will love. And for an extra $200, you can order your Sony A7 IV Marelux housing in some custom color options.
A unique feature of Marelux housings, in general, is their ultra-wide port openings. In most cases, you can remove the port, change lenses, and even install the camera through the port opening. This saves you the time and hassle of disassembling the housing whenever you want to change lenses.
The housing is compatible with a vacuum value, but unfortunately, it's sold separately, as is the manual optical flash trigger.
Depth rating: 330 ft. (100m)
Dimensions: 13.19 x 6.97 x 5.12 in (335 x 177 x 130mm)
The Nauticam Sony A7 IV underwater housing is probably the most well-known out of all the underwater housings on this list. It has excellent ergonomics and first-class build quality. Nauticam has put a lot of thought into designing the Sony A7 IV underwater housing and laid all of the buttons and dials in easy-to-operate locations. An example of this is the way the shutter button and the focus button are positioned. They are almost opposite each other in the top right-hand corner, which makes locking onto your subjects and capturing them very intuitive; imagine a pinching motion.
Another testament to the thought that has gone into designing the Sony A7 IV Nauticam housing is the bayonet-style port attachment system. Ports can be easily attached and removed from the housing with a simple quarter-turn twist.
Nauticam setups give you great versatility when it comes to lens choices, as well as the ability to use all Nauticam bayonet systems, flip adaptors, and optics.
Depth rating: 330 ft. (100m)
Dimensions: 13.39 x 6.70 x 4.92 in. (340x 170 x 125mm)
The Ikelite 200DL Sony A7 IV underwater housing is made from durable polycarbonate material, making it lightweight, easy to transport and use and immune to any form of corrosion that may become an issue with aluminum housings. A secondary benefit to being made from polycarbonate rather than aluminum is that it's more affordable than some of the other underwater housings on this list. Not only is it more affordable, but it also comes with a vacuum valve out of the box, which will help budding underwater photographers save even more money. You will have to purchase the vacuum pump separately, however. The vacuum system, combined with Ikelite's new dry lock (DL) port system and a clear back, which lets you see if there are any leaks, means your camera will be safe from water damage.
The Ikelite to Canon TTL converter is one of the fastest and most accurate trigger systems out there, which is why many people turn to Ikelite housings.
This 200DL version which is depth rated to 200ft. is the big brother to the Ikelite 50DL (listed below).
Like all Aquatica housings, the Aquatica Sony A7 IV underwater housing is a tough, robust housing that puts functionality first. They are often used in the military because of their reputation for being able to take a beating and perform well in challenging situations. The Aquatica Sony A7 IV underwater housing is milled from a single block of aluminum, has an anodized coated, and a standard depth rating of 300 ft. (90m) which can be upgraded to 450 ft. (140m), making them a popular choice among tec divers.
The housing can be ordered in a range of custom colors and can even be manufactured with your logo embossed for added customization, none of the other housings in this guide offer that.
Aquatica housings come with vacuum valves and sensors as standard, which is a big plus. They are also compatible with many flash triggers and sync chords, making them versatile and customizable.
Depth rating: 300 ft. (90m) upgradable to 450 ft. (140m)
We like to call Isotta housings the "Ferraris of the seas" thanks to their striking, vivid red color. The Isotta Sony A7 IV underwater housing is undoubtedly a premium product, and it feels like one when you hold it. Constructed from anodized aluminum, this Italian-made housing is perfect for those who prioritize luxury over cost.
It is well-balanced and surprisingly lightweight, even compared to polycarbonate housings. But the most significant difference between this Isotta Sony A7 IV underwater housing and all the other housings in this guide is its bespoke nature. All Isotta housings are made to order, giving you a lot of scope for customization, but you'll be waiting around a month for it to arrive after you place your order because of it. You can purchase an Isotta housing through Bluewater Photo, and we'll help ensure you get something that meets all of your needs.
Ergonomically, the housing is first-class. All buttons are laid out in a logical manner, and the handles are super comfortable too. Even installing and removing the camera is easy, with a single screw that locks and unlocks the bulkhead.
It has a built-in moisture alarm but no vacuum system, unfortunately. Third-party vacuum systems, such as the Vivid Leak Sentinel V6 and pump, are available.
*Built to last, Compact Size, Elegantly Engineered*
The Sea & Sea Sony A7 IV underwater housing is a robust design that feels solid in hand thanks to its high-quality aluminum construction. Sea & Sea make excellent strobes, and as you'd expect, their housings are compatible with them with a TTL flash trigger. This combination of Sea & Sea housings and strobes makes for the most accurate strobe system on the market.
A large LCD screen on the back of the housing and a viewing window on top means you have an unobstructed with of your camera's setting and menu options while underwater, which is a big selling point for this housing. Another feature not found on many other housings is the glow-in-the-dark buttons to help you when diving at night or in dark waters.
Depth rating: 330 ft. (100m)
Dimensions: 13.0 x 7.4 x 5.2 in. (330 x 189 x 131 mm)
