X-Pro2 fw 2.00 and XF35/2 focus issues

[Hans K Aspenberg]

Upgraded my X-Pro2 yesterday and since the XF35/2 was mounted, I did a few test-exposures of the carpet on the floor in my rather dimly lit office. (Not the most interesting subject though). The first I noticed was that the lens rather slowly attempted to find focus by moving to closest focus, then infinite and then back again to close before giving up. It used about 1.5 sec to not to find focus. Putting on a bit more light made it focus correctly in no time. Really snappy, and snappier than before. This is new behaviour. Before, it snapped into focus or gave up in less than 0.5 second under the same dim light. For me it seems like the new algorithm needs more light in order to find focus. Anyone else that have experienced the same? The AF-mode is single point (central, as small as possible), single shot.

Or the algorithm does not give up that quick any more and tries a bit harder?

[Hans K Aspenberg]

Maybe, but for me it seems like the old firmware managed to find focus in  - say - half of my attempts in dimly lit conditions. Now it's significantly slower and won't lock in more than 1 out of 10 tries. I'll do some more tests today.

I can't confirm that at all. I would rather say it seems to be faster and snappier... even under the darkest conditions.

Still the case here. Haven't done any test with other lenses yet, but I will. This is also an interesting thread: http://www.fuji-x-forum.com/topic/4157-af-speed-with-ovf-significantly-slower-than-evf-x-pro2-fw200/

It can get "lost" when that happens focus on something contrasty at the similar distance - that's the fastest way to recovery in my experience.
