First experience with AFr (focus recompose) for Phase One XF

Medium Format Systems and Digital Backs - The GetDPI Photography Forums - www.getdpi.com
I updated the firmware to feature #4 today, ran the new focus calibration which ended up at the same setting I had previously for the 80mm blue ring lens. It feels as if the automatic calibration is simply a tool to make sure everything is set up correctly to calibrate your lens, i.e. correct amount of light etc.

So, here's my 50 cents regarding the focus recompose (AFr) feature:

+ zoom to focus point works very well in the preview. It seems to be spot on where I focused originally.

+ It works, if you do the same recomposition every time, or similar recomposition

- If you use AFr, take a shot with recomposition, and then take a shot straight on without recomposing, the shot will always be out of focus

- It's mostly accurate only if you recompose the same way all the time

All in all, weird that zoom to focus point is always spot on but not the focus itself. I feel there's a lot of improvement to be made. If I require the same recomposition all the time, it will surely be activated, but if not it's just weird to feel that the first recomposition will be out of focus.
