Sony A7R IV Underwater Review
We think the Sony A7R IV is the mirrorless camera of the future, and certainly a top choice for underwater photographers. Now that underwater photographers will have access to so much resolution, we can’t wait to see the caliber of art produced in the next few years. Macro photographers will especially be able to crop to their hearts desire! The well-roundedness of this camera makes it perfect for macro, wide angle, supermacro, pelagic shooting, and pretty much any other type of underwater photography you can think of.
Our team at Bluewater Photo was fortunate enough to receive a prototype Ikelite A7R IV housing to use with our new Sony A7R IV camera. We decided to take the set up on our trip aboard the Socorro Vortex - a new liveaboard running luxury trips to Guadalupe Island, Mexico - to go cage diving with great white sharks. After some spectacular underwater moments, we can safely say that the A7R IV is the camera of the year!

Sony A7R IV 100% Crop Test
The only way to truly understand the value of 61 megapixels of resolution is to "pixel peep." With other cameras, pixel peeping can make you feel like you have a bad camera. But with the A7R IV, it brings out details that could not be captured with any other full frame camera. Macro photographers, in particular, can really benefit from 61 megapixels of resolution. Cropping lets you "recompose" your photo in post processing as well as bring out details beyond what your camera could capture with normal composition. Sometimes cropping is the only way to create a photo of an extremely small subject. Here are some 100% crops of macro photographs captured with the A7R IV, that show just how truly amazing 61 megapixels is. Be sure to click on each photo to view them in a larger size.
