All this talk about the M8.2 made me go to my dealer and take them up on the "M8 Test Drive." I mainly shoot an MP with 50 Lux ASPH. I am only an amateur and take mostly pictures of my family. I use Tri-X and print in the darkroom 90% of the time, but I need to shoot color film for vacations, etc. as my family is not too fond of BW.
The M8 test drive demo came with the 75 and 35 summarits. I didn't bother with the 75 as the framelines are too small for my taste. I used my seldom used 35 cron instead, fitted with a Leica UV/IR (from the 35 summarit).
Mainly from an ergonomics perspective (the film v. digital, IQ versus other cameras have been debated to death), I have some minor concerns.
a) Shutter sound. This thing is just a little too noisy compared to the MP. Even my kids noticed the crunch sound.
b) Framelines are too close. Having programmed my brain to look for the outside frame lines when usong the 50, the inside frame lines of the 35 are confusingly close to the outside frame lines.
c) The M8 is a little too fat for my hands and there is no place to hang my thumb. Not a problem with the 35 cron, but the 50 Lux ASPH feels front heavy.
d) The shutter is not very smooth. I have a TA softie that I never use with my MP. On the M8, it is a great addition.
I can live with and get used to (b), (c), and (d). However, audible noise is a major concern for my use. I can only take one picture before my kids notice I am taking their picture. If Leica can fix that in the M8.2, I will be very tempted to get one. Otherwise, I will get another MP or the new Nocti. If Leica offers a choice of uncluttered framelines, so much the better!
Overall, the camera is great and I have no problem with ISO 640 and below. While I have some concern with ergonomics compared to an MP, the M8 is the most fun digital camera I have ever used. I borrowed a friend's D700 for two days and I wanted to return it on day one, LOL. I still have one day left on my 3 day test drive, and I am already wishing I don't have to return it. Now I know why lots of owners are very happy with their purchase.
