Has anyone had any focussing issues with the a99? On my very new camera I prefer to use spot focussing. I did a couple of photoshoots over the weekend and noticed that all of my images - the centre focus is out, anything that sits a few mm to the front or back are in focus but my target is out? I've used the Sigma 24-70mm 2.8, the Sigma Art 35mm and the Sigma Art 50mm - same results. Just tried it now, in good light on 3 pencil tips, one a couple of mm behind, one a couple of mm in front, the center one is spot focussed but on an the image it shows the other two to the left and right in focus????

I've got the latest firmware v1.02 - at a loss really, no problems on my a900. I've tried the other focus positions and it's hit and miss with those.

Thought I'd ask here before I contact the place I purchased from.

Thanks again
