Thank you for your reply. I also think lens is the problem... But I don't have any lens to test right now. I should go to the store where bought it and test it.

Hello. I am using a7r3 + sigma 15mm with mc-11 + S-turtle smart ttl trigger. There are several problems in using this combination, so I would like to ask for advice. The first is that photography delays occur depending on the aperture value when S-turtle trigger is On. 1. Exposure step is set at 0.3ev in the camera. It is taken as soon as the shutter is pressed at F2.8, 4, 5.6, 8, 11, 16, and 22. But if it is taken with the values between the above mentioned values such as F3.2, 3.5, there is a delay of about 2 seconds until the shooting. 2. Exposure step is set to 0.5 ev, it is normally photographed without delay in all aperture value areas F2.8, 3.54, 4.5, 5.6, 6.7, 8, 9.5, 11, 13, 16, 19, and 22. There is no problem at all when the trigger is not used. Delay occurs only when 0.3ev setting + Trigger On. I wonder if the symptom occurs due to a lens problem. I bought used lens... If anyone uses the same equipment setting as me, I would like to ask for advice. Thanks. a7r3(0.3ev)+s-turtle.mp4

Hi. I'm Min from South Korea. I started scuba diving four years ago, used cameras such as GoPro, Tg-6, and Rx100, and then moved over to the full frame to find information and joined wetpixel. My equipment is A7R3 with Nauticam Housing + Sigma 15mm Fisheye with MC-11 + S&S YS-D3. I'm happy to be here!
