Another thread has led me here.
I've read and seen the potential issues with the R7 and the Sigma 150-600C pulsing issues, it's been touched on elsewhere on the forums and also, Duade Paton's YouTube video is quite telling too.
I have both the R7 and Sigma, it's my goto combination for wildlife. I've not really noticed anything pulsing wise. Achieving AF with the Sigma seems to be fine on my R7, if not quite as fast as EF glass. I don't get any hunting though, unless the light is really low.
What I have noticed though is that when shooting in bursts, especially at 15fps, in Electronic First Curtain, shots can vary in sharpness, with one being tack sharp, the next in the burst is soft, as are the following 2 or 3 shots, then it's sharp again.
Is this the pulsing issue or is the pulsing happening during achieving and holding AF before any shots are taken? It may be one and the same thing but as I say, I don't get any (noticeable) problems acheiving AF but I do see a difference in sharpness between shots when shooting fast bursts, from one shot to the next.
I'm thinking that it may be an in camera setting for me. When I noticed this, I wasn't sure if I had the in camera stabilisation on or off and I was on a tripod. If it was on, this might have caused the problem with the sharpness between shots. I know IS was off on the lens , as I only ever switch that on handheld. I make sure now IS is off in camera too, before I head out as I always use a tripod. I've not had a chance to test the theory though.
I might be being a numpty here but at 15 fps, once AF is achieved, surely there isn't enough time between shots for AF to wander?
