Not considering medium or large format then, huh? My wife made fun of the 20x24 camera, even helped me set it up on the tripod, joking all the time, til she saw a 20x24 contact print, her jaw hit the floor.
I have my choice of Pentax 645 or 67 as well. 645 is a wonderful "field" camera.
Prior to my move to lighter, more compact equipment, the enjoyment is realized at the end when I see the fruits of my hard work in a final print. Simply... put.. it was
hard work. I couldn't carry all of it all the time. I couldn't meet my wife afterwards at the mall and still be comfortable. It gets in the way in both transit as well as shooting. You experience the world in tunnel vision. I couldn't carry it with me during my wife and I's rare dressed up dinner affairs.
With the rangefinder, the enjoyment is realized behind the camera, to the click of the shutter, to the processing, and to the final print. It becomes an extension of you rather than something you carry. This in fact is something that a medium or large cannot accomplish either. Yes.. better quality negative.. sure.. but soo many occasions to take photographs that would have otherwise been impossible with MF or LF (even an SLR).
For one... I was able to photograph the birth of my son AND participate at the same time. I actually have a photo of my son a minute or two before he was declared "born" taken during the cesarian section with the umbilical cord still connecting mother and child as the doctor passed him to the nurse. Again.. an opportunity otherwise impossible to take with any other camera but a rangefinder (or similar). That one photo is considered (in my mind) as my
masterpiece. It was taken "blindly" with my camera prefocus set, held with only one hand and with the camera taken over my head (I was focused on my wife's eyes at the time.. it was a delivery full of complications.. she was extremely tired). The photo is literally full of life in an extremely sharp photo.
For those that follow the "snapshot" thread debacle... this is the one event that convinced me that a "snapshot" can and IS photography. For the same reasons that many journalists that snapshot events and news are also photographers.
I'm not knocking SLRs nor larger formats.... simply tools with a different purpose. I still have zooms with my Canon.
btw.. the only issue I had with the camera was when I had the nurse take a few photos of us. She (understandably) didn't understand the concept of prefocus and stepped too close for one of the shots... oh well...
