I've had my XF since late last year and while I really like it it's not without its issues. I've been working with my dealer to diagnose and correct them, but they're still issues.
Lock-ups. Almost every tethered studio session has at least one lockup where I have to power cycle the back/camera to clear (IQ 260 back, all the latest firmware).
Focus. Most say it's night and day different from the DF but in my experience it's more like night and a different night. I still have to double or tripple tap to focus and I think I still have more out of focus than I did with the DF.
Construction. The grip had a noticible feeling of play in it that I eventually traced to a loose screw that needed 2 or more turns to tighten (top-left screw on the back of the body).
Power button. press it a little too firmly or off-center and it sticks down. I try to avoid touching it.
Features like focusing stacking don't work well. Lens doesn't repeat settings correctly.
And of course there's the decision to change the remote socket and it's taken a year to release a cable. There still doesn't seem to be a way to trigger from a Pocket Wizard.
I love the idea of the XF and some of the features are a great addition. I feel like it has great potential, I just hope that the potential is realised soon.
Anyone else having these kinds of issues?
