True. But the Zenzanon lenses are great - independent of the shutter.
I tend to agree. I'm not sure I've seen any sign of light-fall-off
with the lenses wide open. Sharp images into the very corners.
One though may wish to shave a half stop off the wide open
rated speeds; 60 and 75 mm. Seiko Electronic shutters.
I bought new an ETRSi outfit as the AEIII prism was offered
half price. Very nearly bought the SQAi. Why the ET? Because
of the lens selection; 75mm vs 80 normal and 60mm vs 65
moderate wide angle. Also ET lens speeds are a little
faster and the lenses a little less expensive.
Turned out eye level was not my cup of tea at all. A real
pain in the neck. The camera is always used with a tripod.
So I bought Bronica's Rotary Finder. A real pleasure to use.
It makes for bright, sharp, comfortable waist level viewing.
As it came the ETRSi's screen was disappointing. So a
Beattie screen was ordered and installed. BIG improvement.
That with the Rotary make for very easy focusing even in
the deep dark woods. Topped off the tripod with a 410
Gear Head from Manfrotto. Very precise, no play, and
always locked for final adjustments.
All in all, the camera is now very usable. Dan
