Bessa is a good way to go
M2 great camera in the late 1950's, it's built like a tank. That's about it. Loading is slow, they improved it on the M4, but that camera is also dated. You have a top shutter speed of 1/1000 sec, poor flash sync at 1/50 sec. cloth shutter curtains, so you have to be careful not to burn a hole in the shutter, (read up on this). In fact, Leica updated the shutter in both the M8 and M9 to Copal vertical run metal curtain shutters because they are electronic, better performance and are very quiet, (not as quiet as the old cloth shutters),Also no shutter burn, bounce or light leaks. It's the same shutter company of the Voigt's and Zeiss, The meter is dead accurate, very center weighted on the manual bodies, you will be impressed. the RF finder is bright and clear and does not flare up, the frame lines are clearly visible in all light levels. The focus patch works as a regular RF split image and also as a split focus in the patch edges. The new line of Bessa's are all metal and have a great feel to them. The lenses on the voigtlander's mount close to the film plane, so sharpness is amazing. You can't go wrong. I purchased a Voigtlander R2M last November, I have put at least 200 rolls of Tri X through it in all types of weather and it has not missed a beat. I bring it with me at all times. I haven't used my M4 since I bought the Voigtlander R2M. The R2M, R3M and R4M all have mechanical Copal Hybrid Shutter. The shutter has two sets of curtains, grey in front, black in the back. Because there is no mirror box in a RF camera light can leak over time and wear, Voigtlander uses this unique shutter to eliminate light leaks and shutter burn problems and the shutter is sightly louder than an M6.
