I am shooting with a Canon EOS 6D and 24-105mm lens.
I've been expereiecning a problem during product photography where my first shot will be shot at F7.1-F11. Then, I adjust to F13 and the next shot still appears to be shot at F7.1-F11 (whatever F stop I chose), as if there is faulty communication between the camera and lens.
This started yesterday where the next shot after I adjusted my camera to F13 was actually the opposite. It was darker, as if I shot it at F16-F18. I switched my lens, but then started experiencing the problem mentioned above. I changed the body thinking that it was the contacts on the body, but the same problem persisted, even after wiping down the contacts.
I have now tried 2 lenses & 2 bodies and I'm having the same issue. The next image after adjusting my aperture is not shooting at the aperture I've adjusted it to.
I know it's a probelm with my camera and not my lights because it specifically happens after adjusting the aperture. Is there anything else I could try? Does anyone know what this problem specifically is so I can get it repaired, if neccessary?
All 3 are disabled, as we are shooting an Manuel mode. I changed the body again & it hasn't happened. Perhaps I just had two bodies with faulty connections.
Are you using any strobes or flash? If you are in Manual shooting mode, then nothing should automatically change, not even ISO. If you press the [Q] button, does it show "M" for Manual shooting mode?
