Hi, I would like to get into the Leica R system and am considering the R6. I like the total mechanical aspect of it due to intended use in possible adverse environmental conditions (cold, rain, 2 weeks without electricity etc.). My question is for users who feel there is a significant benefit to the R6.2 over the R6. Most likely I will be starting out with a normal lens and then a wide angle, then tele etc. Is the 1/2000 additional shutter speed on the R6.2 worth side stepping the R6? Are there any other notable differences? Thanks in advance.
