I got into rangefinders because I wanted something small with high IQ. There are several reasons why I am going RF. However, I wont abandon my digital DSLR bodies.
At this stage, I am finding myself to be more the rangefinder "type."
Simply, I was tired of lugging my Canon APS-C dSLR. I then got into a micro 4/3 camera (E-P1). Great IQ in a small package BUT, BUT it is still not full frame.
Meaning, I couldn't get the kind of shots I wanted. Night time (available light) type street photography with dreamy bokeh and narrow DOF.
A DSLR (even film SLR) has a mirror and you get that camera shake. Also, DSLRs are not exactly small. Now, when micro 4/3 cams have lens that are super, super fasts 1.2-1.6, I'll be using my E-P1 a whole lot more.
So, with that in mind, I started buying older RF cameras to see if it suited my style - Yashica Electros, Canon QL17, Minolta Hi-Matics. At $10-25 (craigslist and flea market),
they were worthwhile experiments. My Canon has a broken meter but I shot several rolls and I like what I got.
I use an iPhone app to help with metering and this has helped me become more acute to lighting; and thus making me a better photographer.
I also came to the conclusion, I want full-frame and wide as possible. 24mm-40mm fast primes which comes out to 48-80mm on cropped digital sensors. There is no way I am spending $2500 on a Canon 5DM2 plus the assorted lens with that.
Have in mind, my $20 Canon with a 1.7 lens and dozens rolls of film is still cheaper than a full rig FF DSLR with 35/50mm prime lens. So far, I am loving the shots I have taken.
I now prefer using my film RF cameras along with my micro 4/3 E-P1. I recently got a Leica CL with working meter for $300 and I think I've gotten the Leica bug.
I could see the justification in investing in an M outfit. It is all about the lens. I could buy different bodies like a Bessa R3M, M6,MP. The lens could be used with my CL, E-P1, and whatever other RF camera I get. And eventually, when a M10 comes out, I could see me going that route.
I know for a fact,I like shooting with a lens that has a manual aperture ring. I could do either full manual or aperture priority. At this stage, it is still taking me a while to compose a shot and do metering.
So, I will still keep my dSLR. I have a 18 month son and sometimes, shooting with fast AF helps. But for pleasure shots, I will go RF.
