Hi,
I had a shooting two weeks ago using the Sony alpha 7Rii with the 90mm Macro lens in a studio surrounding with two external studio flashlights over a period of 8 hours.
3 problems popped up during the shooting:
_ the autofocus had problems focusing orange surfaces and both displays (VF+big display) showed pulsating, blurry sections everytime the orange surface came into view. I had to use some aid (newspaper) to focus on that objects (orange plastic).
Later, viewing the image on the computer, these objects where sort of allright.
Any ideas (apart from the fact that certain surfaces reflect the light in a way which irritates the autofocus)?
_ after 2-3 hours the displays went black for a few minutes, while still showing all the relevant data (digits, bevel, histogramm etc.) regarding the object. I had to switch the camera on and off with 10 - 20 seconds pause inbetween until it worked again. That happened three times during the shooting, which was a bit embarassing, having the client arround. What is the reason?
_ working with the remote camera control software via my Mac BookPro I also had problems starting the camera as well as taking pictures. This time I had to restart the programme on the computer a few times during the shooting.
It would be nice to get some answers to this problems.
One more thing regarding the manual of the SONY a7Rii: I was missing a section in the manual going into detail with the Live-View Mode. Especially in a studio surrounding with professional flash equipment using a non-optical viewfinder it took me quite a while to find the right information, that you have to switch of Live-View with professional flash. I found that info in YouTube, not in the Sony Forums.
Thanxxs, Thomas
