Thanks Jono. I thought only A7r shutter was that loud?
I guess the smartest thing for me is to stay with Leica M and my Canon stuff. I also still have the OMD-E-M5 and some lenses but don't use it often. Eventually I could replace it with an E-M1 -maybe I just wait until I find a used one in good condition.
If I didn't havethe M I would probably go for the Fuji and accept the problem with the greens or learning another software.
Looks like Jono's made his choice. Maybe. ;-)
The A7 shutter sounds for all the world like my Nikon FM with MD-11 motor drive:
Sony A7 - Continuous capture - video
While a bit loud, I don't find it all that objectionable. The A7r, without the electronic first curtain, is a bit more clattery (and slower).
The Olympus E-M1, by comparison, is quieter than an M9 and almost as quiet as an M4-2 in single shot mode (just like its SLR forebear, the E-1, was).
My preferences are clear: the A7 with the Leica R/Nikkor SLR lenses I've acquired is just great, and when I want AF, quiet shutter, superb ergonomics, excellent lenses, etc etc, the E-M1 does the number very nicely.
I have no interest in the Fujis, or any DSLRs at this point in time. (Although I'm going to keep the E-1 since I have all the lenses I need for it and I use them on the E-M1 as well. There's little gain to selling the E-1 SLR body at this point.)
The only M gear I'm going to keep is the Leica CL+CV 21, M-Rokkor 40/90 lenses. Maybe the CV 28mm too. The 40 and 90 work well on the A7 and are nice and compact when I want that. The others work fine for B&W, or color with CornerFix, and are even more compact.
The only question mark to me is whether to keep the Leica X2 at this point. It's such a handy point and shoot, and makes such nice photographs ...
