[Leica] Changing eyes, M focusing

[hoppyman at bigpond.net.au (G Hopkinson)]

Well with our demographics, more than one photographer here with imperfect 
vision and progressives. Maybe I'm lucky that my near
vision deficiency is apparently close to the normal - built into the M's. No 
way I can see enough of the finder frames through any
sort of glasses. I don't know how you guys do it. Have none of the people 
commenting tried the corrective eyepieces? You don't need
variable anything through the finder, just the right correction dioptre. 
Except for folks with more complex vision imperfections, I
guess. But auto focus, PAAH! ;-) Oh OK it can really useful, just keep it 
away from my M's. More seriously AF is a LOT better than
not taking photographs. Heck I even still look at your pictures!
Cheers
Hoppy

No M but progressive specs - gets some getting used to, but then you no 
longer want to do without them - you can drive AND watch the clock for 
instance.
For photography, AF is a fine solution too.(I know some will hate this)
