Re: Focus with 70-200 Sport 2.8

Hi, reviving this old thread because I recently bought an SDQ H to substitute my SDQ and it's driving me crazy for the exact same reason: AF inconsistency, almost always the AF is at least slightly off, which on a Foveon sensor of course gets very apparent when you magnify the image (sometimes it's also completely off, I wonder why, since CDAF should be at play every time).

On my plain SDQ it was spot on almost always, now it's basically unusable for me, with lenses such the 105 F1.4 which have a razor thin DOF, but I've also experienced AF inconsistency also with the 18-35 F1,8 wide open at infinity, so the issue looks real to me.

Was there any follow-up from Sigma? Anyone experiencing the same level of issues with their SDQ H? To me for now it's basically a MF camera, if I want to be sure to have tack shapr pics that this marvellous sensor and Art lenses deserve..
