I normally shoot MF or LF, but when I shoot 35mm it's been Nikon, though I've probably used ever major Japanese SLR at one point or another.
I've had a Barnack Leica for ages, but a while back, I gave in to my long held desire to own M equipment. I ended up with an M2 and an M5 (both with DAG CLAs) and several lenses, the 50mm 'Cron among them. After 10-ish rolls of film between the two bodies, I've come away with several impressions:
- The Leica mystique is so for a reason. There is a kind of mechanical and optical flawlessness to their design you have to experience for yourself. They are elegant and intuitive to use in ways no other camera I've ever handled has been.
- The are absolutely not worth the money, particularly the new stuff. If you're careful, you can get older bodies and lenses at "reasonable" prices, but even so, that's at least 2-4X what vintage Nikon or Canon equipment costs. I have a Nikon 35mm f/1.4 that performs comparably to my Summicron 35mm f/2 ASPH, but the latter cost me multiples of the former. Yes, I got the box, case, shade, etc. with it, which does make it more expensive. But still, paying 4X for approximately the same performance isn't "worth it".
- It's not just about money. I do not know why and cannot quite explain it, but I just "see" differently with a Leica rangefinder than any of my Nikon SLR bodies. Not better, not worse, just differently. This is a work in progress. I have not yet owned Leica M long enough for it to be seamless in use for me, the way my Nikons are.
- It's still just 35mm. You can't beat the dealer here. Negative size matters, and for some subjects with lots of small detail, it matters a lot. Even on a tripod with a cable release, the Leica negatives do not come anywhere close to even an average 645 negative, let alone Hasselblad or 4x5.
I will soon return to the land of larger negatives. I won't get rid of the Leicas though. I think of my many cameras as paintbrushes - each plays a different role in my work. The Leicas and Nikons will continue to see use where- and as it makes sense.
