While I don't have an a7IV but I had experienced a similar issue with my a7rIII while photographing a scene lit at least in most part by an artificial light source. Turning on anti-flicker shooting solved my problem.
Greetings…. I need assistance from the Sony community with respect to the A7RVI vs A7RIII for aviation photography. I’m currently moving from Canon to Sony. I shoot a lot aviation photos. With aviation photography comes a great deal of cropping as the planes can be of a distance. My question comes from a megapixel count for cropping vs which has the better autofocus as planes sometimes are traveling 500 knots at 500 feet.
Which body would be the better choice aviation photography?
Thank you for your time and advice…. I’m looking forward to exploring the world of Sony!!!
