Some early comments about focusing the X-Pro 1 using OVF vs EVF:
According to http://invisiblephotographer.asia/2012/03/09/fujifilmxpro1-firstimpressions/, when using the optical vf:
However, using the EVF for focusing introduces a new problem of the display freezing while focus is acquired - although it appears likely this will be addressed in firmware http://www.amateurphotographer.co.uk/news/fujifilm_xpro1_editors_handson_review_news_311664.html:
According to http://invisiblephotographer.asia/2012/03/09/fujifilmxpro1-firstimpressions/, when using the optical vf:
...the AF point is not quite exact through the OVF for the same reason – even with the “Corrected AF Frame” option on. Using the OVF, you often get 'more' around the edges that you thought you had framed, and every so often, the actual AF may be on the object just to the side of your intended subject, as seen through the OVF. So, while the OVF would likely save you battery power over the use of the EVF or the LCD, the EVF option may yet provide the best AF accuracy
However, using the EVF for focusing introduces a new problem of the display freezing while focus is acquired - although it appears likely this will be addressed in firmware http://www.amateurphotographer.co.uk/news/fujifilm_xpro1_editors_handson_review_news_311664.html:
One thing I immediately noticed is that the EVF locks up while the camera acquires focus, so if you are panning or the subject is moving there is a difference between what you see in the viewfinder and what will be photographed.
From the moment you press the shutter release – until the camera focuses – the view in the EVF remains the same, as the EVF does not refresh while focus is being found. In brighter light the focus will be quicker, but I think this could be an issue for the sort of low-light photographers who will be attracted by the wide maximum aperture lenses the system provides.
I asked Kawahara about this and he confirmed that the model I was using reflected how production models would behave. Obviously, when using the optical viewfinder there is no such delay. The EVF in the X-Pro 1 refreshes 40 times a second, which is a little behind other models that do so 60 or 120 times per second.
But Kawahara said this issue can be improved via a firmware update and is not necessarily a permanent characteristic of the camera.
