"The Sony a7R Mark IV Field Test" - TDS Photo Podcast

This is The Digital Story Podcast #709, Oct. 15, 2019. Today's theme is "The Sony a7R Mark IV Field Test." I'm Derrick Story.

Opening Monologue

It's big, it's beautiful, and it captures 61 MP files: the Sony Alpha a7R IV mirrorless digital camera with 24-70mm f/2.8 lens is a technology marvel. I wrapped my hands around one and spent a month using it on photo assignment, from darkened haunted houses to mid-day festivals on the green. And today I'm going to share what I learned during those shoots.

The Sony a7R Mark IV Field Test

The kit that I've been using for the last few weeks is the Sony a7R IV with G-Master 24-70mm f/2.8 zoom. What a tandem! I basically felt like I could walk into any assignment with just that camera and lens and come away with the shots I needed. It is a confidence-inspiring rig for sure.

In case you haven't been online for the last month, here are the basic specs.

  • 61MP full-frame back-illuminated sensor
  • 15-stop dynamic range, 14-bit uncompressed RAW, ISO 50 to 102,4005
  • Up to 10 fps continuous shooting at 61MP with AE/AF
  • Autofocus: 567 phase-detection / 425 contrast AF points
  • Real-time Tracking and Real-time Eye AF for human, animal and movie
  • APS-C crop mode delivers 26.2MP high resolution images
  • 5.76 million dot UXGA OLED Tru-Finder electronic viewfinder
  • High-speed 2.4 and 5GHz Wi-Fi / FTP transfer and wireless PC remote
  • In-Body Stabilization: 5-Axis Optical
  • Max Video Quality: 4K 30fps
  • Twin SD card slots
  • Weather sealed.
  • After shooting with this camera for a month, here are my real world observations.

    • It's true, low light performance is fantastic. I shot regularly at ISO 6,400 with acceptable results. ISO 3200 is a piece of cake. ISO 64,000 is acceptable for certain situations.
    • Full frame sensor with Sony G-Master 24-70mm zoom is a pro rig. Optics and camera complement each other well. The results are impressive. File dimensions is a crazy 9504x6336 pixels. RAW files were around 123 MBs per shot. Extra Fine Jpegs were 34 MBs per shot.
    • The Jpegs are good, but the RAWs are better. I did my testing with Capture One Pro 12.1.3. The out of the camera RAWs with C1P looked better, especially colorwise, than the Jpegs. This probably had as much to to with C1P as it did Sony. Editing the RAWs, however, provided less headroom for highlights and shadows compared to some of my other cameras. You do, however, get built-in lens corrections with the Jpegs.
    • Autofocusing, tracking, Eye-AF, animal-AF, and everything else AF is impressive.
    • This is also a movie-making beast. Videographers should be very interested in this camera.
    • You have to spend some time to learn the menus and customize the camera. If you don't, it will frustrate you.
    • If I were a portrait photographer only, I'm not sure I would choose this camera. Skin appears more ruddy that with some of my other rigs. I would probably seek out a lens that was better for portraits.
    • The 24-70mm GM produces lovely background and bokeh, however. Its image detail is incredible.
    • Viewfinder, ergonomics, and shooting experience is excellent. This camera is a pleasure to use.

    The bottom line is, I have no problem recommending the Sony a7R IV with G-Master 24-70mm f/2.8 zoom $5,696. If I were to buy a full frame camera right now, this would probably be at the top of my list. And I much preferred shooting with it compared to the Panasonic S1.
