I've owned and used almost daily a black Bessa R for something like 7 months. It is a dream of a camera. The meter is spot-on and I have yet to get an improperly exposed picture.
I bought it from Stephen Gandy with the cv 35/2.5 Color Skopar, which is so shockingly, painfully sharp that it's scary. In fact, when photographing a client's Model A Ford, I actually took it off and screwed on a Jupiter 8 to soften things up a bit.
It is truly an amazing lens. It is as sharp as my Super Takumar 55/1.8 and that's saying a lot. Shucks, it might even be sharper. Who knows? I'm certainly not a techie and into lens testing.
I also own a silver Bessa L with black cv 25/4, another tack sharp lens. The L's meter tends now and then to be a bit on the low side, so I get the meter reading and then open the aperture one click and the images are fine.
I took the neck strap off the Bessa R and am using one of Gordon Coale's leather wrist straps, which I rather like. It's quite a nice kit for street shooting as, without the obvious neck strap, most people aren't aware you've even got a camera.
My Bessa R has spent a great deal of time in a motorcycle tank bag, in the glove compartment of a jeep banging around the Mexican border, and the RF system seems impervious.
When I think of all the cameras in my life, I would rank the Bessa R with the cv 35/2.5 as a "best buy."
Relax, Jin, you're gonna love it. Wish I had it when I lived on Cato Street just off Edgeware Road.
