Moving away from Sony cameras

May 2, 2022 JimK 17 Comments

I’ve been using Sony cameras for well over ten years. When they came out with the NEX series of APS-C MILCs, I was all over them. I fully committed when they introduced the alpha series of FF MILCs. The Sony FF cameras, I have owned: a7R a7 a7RII a7II a7RIII a7RIV a9 a9II RX1R I’ve… [Read More]

Stacked sensors and autofocus

Almost all my technical posts are based on research and testing. This one is different: it is entirely speculation.

Sony a7III, a9, a7RIII SmallRig camera plate

June 28, 2018 JimK 8 Comments

I just received a couple of the SmallRig Arca-Swiss plates for the latest generation of Sony alpha 7 and 9 cameras. They are quite a bit cheaper than the RRS plates and have some interesting features, so I decided to do a short report. With the RRS plate, you can order a version that has a… [Read More]
