Re: Sigma 17-70mm f/2.8-4 Dc and MC-11 Converter

This helps a lot! Thank you very much. It's great to know that the Sigma works well on the a6000 too.

Maybe I'm asking a bit much, but may I ask: how fast is it exactly on the a6000? Around a tenth of a second, like native lenses, around half a second, or more? I suppose AF-C in photo mode doesn't work, as it also doesn't work in video mode?

If its in AF-C and the lens is close to be in the range of focus, it's about a tenth of a second to acquire focus.  If your completely out of focus range, it will take about 0.5-1 second under good light.  If the lighting is poor, the lens and adapter switches to contrast detection and it can take a couple of seconds for autofocus.
