I don't think much of the 2007 Chevys. I gotta be honest, I'm no fan of the Argus or the Zorki either. Not sure I would still be in rangefinders if they were my first and onlys - sorta like trying Folgers Instant and deciding you don't like coffee.
I have two Canon DSLRs and would agree that they are more capable than my rangefinder cameras. Longer lenses, faster focusing, 8 frames a second if need be, the ability to switch ISOs on the fly, adjust white balance, exposure compensation - they are a dazzling bit of technology. Wonderful cameras. I cannot take a better picture with my rangefinders than I can with my Canons.
You either like using rangefinders or you don't. I find them addicting - it's almost like golf.
I play golf and the ball is all over the course - woods, rough, traps, I am there. But occasionally, you hit one just right and it's like a drug - at the end of the day, I remember those shots and I keep coming back to the course.
I develop a roll of film and there are plenty of misses - but the keepers are the ones that do it for me in a way that I just don't experience with the big Canons. Maybe it is because I had to work harder to get them, I dunno.
But, to each his own - enjoy the DSLRs, Bill.
