You should probably borrow a rangefinder or purchase a film one (they are some inexpensive options.. Canonet is a wonderful choice). They are a different tool that fits a certain style of shooting. There are lots of advantages and disadvantages that are outlined in the posts above. Honestly, jumping into a digital rangefinder (there are only two. R-D1 = expensive. Leica M8 = REally expensive) without any previous experience with rangefinders is probably not a smart move.
As for me... i love mine. I own a few rangefinders and nothing seems to be better for a street photographer.
Specific for the R-D1
ADV:
- Lovely ergonomics. Feel just like a traditional classic rangefinder
- Wonderful user ergonomics. WB, Quality, ISO, Shutter, Aperture all integrated in manual switches and dials. Just like a classic rangefinder
- Good low light performance. Known to be better than most cameras but not as good as the latest coming out of Canon.
- Noise that is present is very film like... pleasing.
- IT IS A RANGEFINDER. Thus all the advantages shooting with one. As outliined above. No TUNNEL VISION.
- Non-obtrusive. Stealthy Quiet. thus wonderful street/journalist style of shooting.
- BIG one in my opinion. M-mount. which opens up to a whole history full of wonderful lenses. Leica and Voigtlander included.
- Just like the classic rangefinder there is a wonderful simplicity about shooting with a rangefinder.
- Looks and acts like a film rangefinder. Attracts less attention.
- Great image quality.
- Pretty darn compact compared to SLRs
- Rangefinder paired with fast glass.. nothing comes close in low-light situations.
DIS:
- Rangefinder misalignment seems to be a popular issue
- Questionable long term support/repair from epson
- 28-35-50 frame lines only.
- Short rangefinder base which means limited accuracy on near and far end
- Slow write time to SD card
- 6mp although that has never limited me...
- ITS A RANGEFINDER.. All the disadv of a rangefinder. Not good for macro and telephoto for example.
- Battery life is good but limited. it uses lithium-ion which has adv and disadv in of itself. I carry 4 with me.
- The cost of a digital rangefinder + lenses can really buy some nice high end Nikon and Canon stuff.
- no such thing as a zoom. the Tri-Elmar isn't really a zoom more like a lens with 3 settings of focal lengths.
- No Autofocus and all he gagetry found in the latest SLRs.
- 1.6 crop
If I think of more.. I'll post. BTW.. If you do decide on an Epson R-D1, they are pretty darn difficult to find. Interestingly, their popularity has increased since Epson discontinued them and Leica released the M8. So save up and be ready to be quick if you see one for sale.
My Epson R-D1 with Noctilux (which is physically the largest lens in leica line.. most rangefinder glass is very compact/small).
As far as I know, there are only two active members here that will have input... Iron Flatline and I. Haven't seen others but I could be wrong. Iron is the guy with both Leica M8 and the R-D1. I personally decided against the M8 and will wait for Leica's next iteration of the digital rangefinder.
There is something intangible and hard to describe when shooting with a rangefinder.. you just seem more involved in the actually creation of a picture while shooting with an SLR can feel mute and removed from the subject.
