Focus with Range Finder
I've been on the fence for years about getting one of these. It's just that I'm so used to slr's that I'm not sure how I will adjust to a rangefinder. I mean, I was looking at a used 7 last weekend and I just don't see how one can focus as quickly as a slr. I can manual focus a slr pretty fast and accurately which is a necessity when you shoot a lot of street and protest photography as I do. Having to match up those two bars on a moving subject just seems impossible to me, not to mention that I see no way to focus on anything that is not dead center where those bars are. How does one focus off center?
Like you, I was nervous about spending mucho $$ on a rangefinder when I had never used one. I can report one gets used to the RF method very, very quickly. With the exception of my view cameras, all my cameras (MF, 35mm) are SLR and I got pretty good at focusing with SLRs - like you.
If a subject is moving, the minute you focus with an SLR, the subject goes out of focus! . . . the subject is moving, correct? Unless, of course, the subject is moving on a plane perfectly parallel to the the film pane of your camera - hardly ever the case
After a little while, the RF lines start to look the the split center screen with your SLRs. I am not sure what you mean by "the bars" . . . with the RF, all one needs to do is align the 2 images.
If you want a hand-held 6cmx7cm camera that lets you take pictures fast, this Mamiya 7 (or 7ii) is, in my opinion, the way to go.
If you purchase a camera from a store that allows returns with 14 days, you can always use it for a couple of days (while taking extremely good care of the unit, of course) and see if you can get used to the RF method.
Hope this helps.
