A Comprehensive Review of the Sony a7R IV

The Sony a7R IV brings the company’s latest innovations and improvements to the popular line of high-resolution full frame cameras. Along with its new sensor come a bevy of new upgrades and refinements to existing features, making it an interesting choice for a lot of photographers. This comprehensive and thorough review takes a deep look at the camera to help you decide if it is right for you. 

Coming to you from Maarten Heilbron, this excellent review takes a look at the Sony a7R IV. The a7R IV features lots of upgrades over the a7R III, the most prominent being the new 61-megapixel sensor, an upgrade of almost 50% over its predecessor. Along with the new sensor comes a better EVF, more ergonomic grip, more powerful autofocus, better weather-sealing, and more. The capability to fire at 10 fps at 61 megapixels is certainly a boon for many photographers, particularly wildlife photographers, who retain vast cropping capabilities with enough speed to capture animals in action, all supplemented by the capable autofocus system.

Sony a7R IV is Still a ‘Star Eater’ After a Certain Shutter Speed: Report

If you were hoping that Sony had finally completely removed the long-exposure noise reduction that causes its high-resolution a7R cameras to “eat stars,” you’re going to be disappointed. According to Jim Kasson, the Sony a7R IV eats stars to about the same degree as the a7R III.

Over on his blog, Kasson posted dark field spectra results for the Sony a7R IV at 1/8000 of a second, 2.5 seconds, and 3.2 seconds. The dark field spectra for each color “plane” at 1/8000 and 2.5 seconds look mostly flat: in other words, the way they’re supposed to.

But once you hit 3.2 seconds, as Kasson puts it, “all hell breaks loose” in every channel, and it’s particularly bad in the blue channel. You can see all the charts over on Kasson’s blog.

Why I Bought the Sony a7R IV for Wildlife Photography

Why I Bought the Sony a7R IV for Wildlife Photography

Before today’s launch of the Sony a7R IV in the U.S., I had the opportunity to use the new 61-megapixel camera on a few occasions. Ultimately, these hands-on experiences led me to purchasing it for animal photography and in this article I list a few reasons behind the decision.

First, a quick disclaimer. What I write below is not in defiance against any other camera system. Every major camera brand has absolutely killer options for bird and wildlife photography. My list consists of some features and specs I identified wanting in priority over other nice things to have in a camera, and everybody’s own personal requirements will be different.

Sony a7R IV, FE 200-600mm G, 1/1000 s at f/6.3, ISO 200. Crop mode active.

Megapixels

Hey, don’t laugh. I didn’t think a million megapixels would be a defining factor either. Yet here we are.

As all the headlines are quick to point out, the a7R IV has a 61 megapixel sensor. For some genres of photography, this is surely overkill. For me, I crop just about every single photo of wildlife I shoot to enlarge the animal in the frame. With the a7R IV, I’m never cropping down into the “danger zone” territory where the final resolution is pretty much only good for Instagram sharing.
