My problem is that I have too many already. Currently, I have 3 Rollei 35's (1 (German) Tessar, 1 S-K Xenar, 1 Sonnar), 2 Oly Trip 35's (1 black, 1 silver), countless Canon QL-17 GIII (probably close to 40 of these), 2 Voigtlander Prominents, 1 Minolta 7Sii, 1 Yashica IC 1.4, 2+ Yashica Electro 35 GSN's, 2 Oly XA's (one with shutter issues), and some others that I can't name off the top of my head ATM.
(...)
The Yashicas are kind of clunky feeling to me, and the batteries are a nightmare.
The Canons I have yet to keep one for myself. I refurb them and resell them. I keep saying I should use (keep?) one for myself, but I just haven't gotten around to doing it.
Ok, want the short answer? Grab a Kodak Retina IIIc before prices rise. Build quality and lens quality are extremely high, you would think this was a Leica. Compact; the lens is always protected, the rangefinder is precise. It can also be used as a scale focusing camera because the scale is good and clear. It is my favorite 35mm camera, and I have owned a lot of 35mm cameras.
If you can't grab a Kodak Retina IIIc, an alternative is the Agfa Karat IV, particularly with the 50/2.0 Agfa Solagon, or Schneider Xenon, or Rodenstock Heligon. The Solagon is amazing !
Long answer...
Rollei 35s: i own one and i find it limited; i need to use f8 or smaller to be sure that my focusing is OK. And i am very good at estimating distances, mind you. Also, it is prone to camera shake so for me it's 1/60 or higher shutter speed. In short, limited. Leave it to the collectors. If you want something better get a Minox 35GT. But they are not very reliable, and have no manual exposure setting.
Olympus Trip 35: It is a limited machine, but you already knew that. Otherwise, a very nice machine and quick to use.
Oh, and I've been eyeballing the Olympus 35RD and the 35SP as potential candidates as of late.
Olympus 35SP: Overrated. I found the shutter action to be too noisy, I also felt a bit of shutter vibration which is a sin for a leaf shutter.
Olympus XA: Yes, very compact and cool and advanced, but that lens is crippled.
Canon QL-17: The lens is not as good as the 45/1.7 on the Yashica. I don't like 40mm focal length too much, to be honest.
Minolta 7SII: A bit bigger and heavier for what it brings to the table.
Yashica Electro 35GSN: Yeah, it is big, but the batteries are not a nightmare. One CR2 battery + two PX625A batteries, wrapped nicely, are a good substitute. I find this camera to be much better than what the features would indicate. The viewfinder is big and has parallax correction, the focusing is smooth, the lens is totally excellent in all respects, the metering is surprisingly accurate, and the camera is tough.
But in all honesty,
all of the above cameras can be surpassed in results by an Agfa Isolette III with a Solinar lens... Which would be more compact that some of the cameras above, and also a rangefinder. And medium format (6x6).
