I'll post some scans later, but my initial tests last week were interesting. I'll post some scans later. But my tentative conclusion is that while the C35 is really nice, it's slightly less sharp than either the Olympus 35SP or the Minolta 7s. The program mode only exposure system seems to be a little weird. It keeps exposures around f8, but I don't know if this is substantially different than the other two.
Colour rendition is pretty consistent between the three, with the Olympus seeming to provide a touch more saturation. Exposures on the Olympus seems to be more accurate, even without using the spot metering option. With colour negative film this probably isn't of much significance, but with chromes it might be important.
As far as handling and other usage factors go, the Konica, for me, suffers two faults. First, its shutter release is a little more sensitive than I'd prefer. Locking in a reading via a half press to override exposure is difficult if not impossible. (I don't have the user guide at hand, so maybe this isn't even supported.) More importantly, the finder has a lot of space around the actual frame. Some space is useful, but for me the C35 has way too much, as if the viewfinder were designed for a longer focal length than the 38mm lens attached. The viewfinder is bright and the rangefinder patch is OK, but is not as easily seen as the Minolta nor the Olympus. The Olympus is the best of the lot, but the Minolta is quite good.
The Minolta is the largest of the three, and I found it to be a bit more awkward to handle, though it was nothing onerous. The Olympus is not as tall, and fit in my hand better. The viewfinder on the 7s really isn't that great. The actual frame isn't delineated very well. The EV scale on the right, while helpful, doesn't clearly show the right edge of the frame. Also, I found the focusing tab of the Minolta to be harder to find, while the controls on the SP fell easily to hand.
Both the Olympus and Minolta only display EVs in the viewfinder. If you work in EVs enough, this isn't a problem. But the aperture and shutter speed controls on the 7s are not as easy to manipulate as the 35SP. To move from auto exposure to manual, you must move the shutter speed ring before the aperture ring will unlock. The slowest shutter speed on the Minolta is 1/4 sec, while the Olympus goes to 1 second. Both have a B setting. Minimum aperture on the Minolta is f22, while it's f16 on the Olympus.
Overall, I like the Olympus better for optical quality and ergonomics. The Minolta is very nice optically, and I could live with it though it doesn't feel as good to me. The C35 handles very well for a smaller camera, and the slightly wider focal length comes in handy. But optically I don't think it's quite up to the other two.
Since all of my shots were handheld and exposures weren't matched, I don't consider my "testing" to be especially rigourous much less conclusive. As I said, I'll post some scans in the next day or so.
