If I am using T lenses I would need to adjust aperture and shutter speeds with the top dials, which leaves no dial left for ISO. I know people usually allow one of the three to adjust automatically - but with EVF cameras I've grown accustomed to setting all the parameters myself. The lack of a dedicated ISO dial is hence troubling.
Interesting. That description presumes mostly manual exposure operation, because in most uses of my cameras (Av mode mostly) I find myself using use the aperture and EV compensation dial. When I go to manual mode, I set ISO first, then am looking through the camera to set shutter and aperture.
If I'm shooting with M lenses, I need at least one focus assist button in the rear. On the A7 I actually map two buttons to focus assist, and use a different button for horizontal/vertical shooting. In tricky light I also go between WB profiles and peaking color/strength without taking my eye away from the EVF (How would I know which peaking color works best if I'm not looking through the EVF when I change settings?), so three extra buttons would be nice.
Well, there's no focus peaking so that's not an issue. The left dial becomes focus assist by default with manual lenses, and for manual exposure mode you have access to shutter on the right dial and aperture on the lens. (I hope the right dial is configurable to EV comp for Av mode.)
I see much goodness in striving for simplicity ... but just how simple is always the twitchy part. I'm sure we don't have the whole story just yet on this camera, but it might be too far in the simple direction for the kind of shooting you do, and maybe that I do.
(I have not had the displeasure of losing any EVFs myself, btw. None of my cameras with clip-on EVF has had a locking clip, and I've not found the EVFs overly eager to leap off over the past 7 years. Perhaps I just handle them a little differently from how you do.)
As I've said, it's a very interesting camera. It's certainly not the best camera for all purposes, but I think it has a viable place in the camera pantheon. It can't replace my A7 for using R lenses, for instance, and it can't replace my E-M1 for total system performance and versatility. It can, however, replace my M9 and X2, which are both somewhat limited range of use cameras in my perception.
Can't wait to get a chance to play with one.
