So I have been loving the silent shutter for wedding ceremonies and at other times when I need to be quiet. Yesterday I was using it during an outdoor ceremony and I started to notice that one of my camera's shutter was lagging every third or fourth time. Almost like I was shooting at a very slow shutter speed. I switched back to the normal mode and there were no problems. Also my other 5D3 was acting fine The only thing I can think was that it was hot and humid but I don't see how that would affect the shutter. Any thoughts?
