Quick review of the new firmware on the XE2
The viewfinder is noticeably smoother post update although you can still trip it up. For focus & recompose it works great, if you are focusing while panning it is possible to cause it to lag a bit although it is less than before and doesn't do it consistently. I feel it is pretty on par with the XT1 EVF I compared the XE2 with on monday before purchasing my camera.
Focus peaking works just as well as before but now you can change the colors. I really like the split level focus screen that you can use so I don't see myself using this much.
They partially addressed the issue of it taking so long to switch back and forth between EVF or LCD only shooting or EVF + LCD by making a shortcut menu for the function that can be mapped to one of the Fn keys on the camera. While this is better than before since you don't have to go into the menus to achieve this it is still not ideal. I would like to see an option for EVF Shooting with LCD playback and menus in the next update, I just can't imagine a situation where I would want to use the EVF to navigate menus or review photographs, but this is the only option you have if you don't want the lcd to be on all the time.
