Hello,
If you are thinking of going digital, would suggest you to go for a Full Frame DSLR as Vic said, or straight to M9 if funds are available. 😀
I had gone Digital 3 months ago with M8/GRDIII from shooting M6 and MF, but I missed full frame film and plan to buy a m6/bessa next month.
Here are the bads,
M8 is loud, I had used a G2 for a week, and it is quieter than M8 for its shutter/rewind sound, but the focus sound of G2 is roughly the same as the M8 shutter/rewind sound. Apparently 8.2 is quieter, but still more noticeable than M6.
The battery life is not impressive, I need at least 2 for half a day of shooting, 4 if whole day.
The extra cost for coding the lens, UV/IR filters, special LTM adaptor if using LTM lens, external finder if shooting wider than 32mm (24mmx1.33) are all to be considered.
The reliability of M8 can be frustrating if you got a bad copy, and the repair cost will not be low if it comes without warranty from a good dealer.
After a few months with M8 and over 3000 images shot, I like the camera as a sharp compact daylight shooter, but not without some hate for its battery /banding/frameline inaccuracy
I would suggest to anyone:
If you are still shooting films and quite happy with your worklow and result, keep going with it as films are still being produced and labs can still process them.
But if you felt the temptation of a digital rangefinder, save enough for M9. As M8 will not be the closer replacement of any analogue Ms/Hexar/Minolta than the M9, it is a compromise between analogue and M9. But even M9 will not be a complete replacement of analogue Ms.
Sorry for the long post and some poor english. 😛
