Sony a7R IV Overview
The Sony a7R IV was announced on July 16th, 2019 and with it the largest megapixel 35mm sensor (61 MP) that Sony has ever put in an Alpha Series camera.
Note: The Sony a7R IV “A” variant was announced in April 2021 and is identical to the original model, but with a higher resolution (2.36M-dot) LCD.
Although I didn’t purchase my own a7R IV on day one, I did pick one up a couple of months later following some very positive reviews.
Since I enjoy shooting wildlife I often find myself cropping in quite heavily at times, so I knew that I would definitely make use of those 61 megapixels.
Here are some of the things that the a7R IV shares in common with its predecessor the Sony a7R III:
- 5-axis sensor stabilization with 5.5 stops of compensation (although the a7R IV implementation has been improved upon)
- 10fps continuous shooting with AE/AF tracking
- 1/8000 maximum shutter speed
- Interval shooting
- Human and Animal Eye AF (Animal Eye AF added to the a7R III with v3.00 firmware update)
- 4K video up to 30p and 100Mbps
- Full HD up to 120 fps
- 1.44M 3.0-in LCD (although the a7R IV “A” version has 2.36M-dots)
- NP-FZ100 battery
- Sony RMT-P1BT Remote Commander support
And here are the new features that the a7R IV gains:
- 61.0 megapixel 35mm sensor
- 26.2 megapixel APS-C mode
- Additional 4:3 and 1:1 aspect ratios
- 567 phase detection points that cover approximately 74% of the sensor’s surface
- Focus frame color selection (red, white, grey)
- Phase detection autofocus extended to F11
- Focus priority aperture drive
- Eye AF in movies and no recording time limit
- Improved in-body stabilization
- 5.76-million-dot electronic viewfinder
- Dual UHS-II SD card slots
- Built-in digital audio interface
- Improved grip and buttons
- Pixel shift now supports 16 full-resolution images
- A blue focus peaking color has been added
DPReview awarded this camera their Gold Award and concluded their in-depth review with the following:
The Sony a7R IV is among the most capable cameras we’ve tested. It makes a compelling case that the days of choosing between speed-oriented cameras and resolution-oriented cameras are coming to an end. It wouldn’t be our top choice for sports and action purists (all those megapixels result in many megabytes of storage), but for those users that need this resolution on a regular basis and want to be able to photograph fast-moving subjects when necessary, the Sony a7R IV is the best option on the market right now.
DPReview
The a7R IV has very quickly become my most used Alpha camera. Unless I’m going out to shoot birds in flight, then I’m pretty much always going to be packing the a7R IV in my bag. That said, the a7R IV is still perfectly capable of shooting birds in flight as well.
I also find myself using it with the Sony E 70-350 lens in APS-C mode as this makes for a really light setup, especially when I’m walking my dog Frank and can’t manage to hold the FE 200-600 at the same time.
The only real disadvantage to the a7R IV is that it doesn’t handle low light situations so well. I do find myself using Topaz Denoise AI more often with this camera.
Overall the a7R IV is a great all-rounder and it will be interesting to see how Sony can improve upon this when they release the inevitable a7R V.
