This can be seen in the shark photos featuring beautiful gradients between the light rays going through the water and the shadowy blue water. In our tests, we found that the dynamic range performance on the A7R IV did not appear to be hindered by the high resolution. Sony is claiming that the A7R IV will maintain the 15 stops of dynamic range at low ISOs that was available on the A7R III, and in fact, the ISO range is the same. With R standing for resolution, the main upgrade to the A7R IV is a new 61 MP sensor from the A7R III’s 42.4 MP sensor. The predecessor of the A7R IV, the Sony A7R III, is the most popular full frame camera for underwater photography.

After that we took the camera to dive with Blue Nation in Loreto, Mexico, and we're looking forward to taking it further south to La Paz for our annual photo workshop.īluewater Photo Sony A7R IV Camera and Housings: Our team at UWPG was fortunate enough to receive a prototype Ikelite housing for the Sony A7R IV. Its well-roundedness makes it perfect for macro, wide angle, supermacro, pelagic shooting, and pretty much any niche of underwater photography you can think of. And this camera isn't just for macro photography. Especially macro photographers who can crop to their hearts desire. But now that underwater photographers will have access to so much resolution, we can’t wait to see what they can do. This was a camera made to be a photographer’s workhorse.īy releasing the such a high resolution camera, Sony is beginning encroach on the realm of medium format photography – which hasn’t traditionally seen much attention by underwater photographers. This isn’t a camera that was just made for specifications.
For those photographers that might be put off by the ludicrous number of pixels – the A7R IV appears to be a fairly versatile camera with plenty of capability for day-to-day underwater shooting. The A7R IV can still accomplish 10fps continuous shooting (7 second buffer), real-time AF tracking in video, and a Pixel Shift Multi Shooting mode that can create 240 megapixel photographs. The A7R IV features a 61 megapixel full-frame Exmor R CMOS sensor – the most megapixels of any mirrorless camera to date. And if you already thought the Sony A7R III was a top camera, well the A7R IV is almost 20 megapixels ahead. On paper, it puts Sony solidly at the top of the mirrorless camera market and potentially as one of the best underwater cameras available. The release of the Sony A7R IV was a complete bombshell. Sony gets a lot of credit in the photography world for innovating.
