I want the 1:1 format option, selectable via soft key.
I am using the '7 with the MS Optical Perar 35/3.5, and I have set the camera up (unintuitively, for me) to P mode, as suggested by Jono on another thread; it's magic.
I say 'magic' because the back dial now controls ISO, and there's a direct read-out of shutter speed in the EVF—so you can make that critical balance between ISO and speed with the one dial. Anyway, a bit OT, but thanks Jono!
The only drawback of the '7 for me is no 1:1 format. I know we can crop, but having the finder showing 1:1 'clear' and shading to show the rest of the sensor would be brilliant for me personally.
For the request list!
