Subject: [Leica] M8 upgrade - 90 Cron APO focusing problems

Hello Luggers,
I have been having a dialogue with Schmidt (the local Leica  
distributor) about getting my 90mm Summicron APO to focus properly on  
my M8. Despite adjustments to the lens it still back focuses wide open  
in the close range.
Trying another tact I decided to go for the M8 upgrade to the  
viewfinder, and that led in a cascade to the new shutter upgrade and  
in a what the hell attitude I also opted for the scratch resistant  
LCD. I now have the camera back and my 90 Cron is no better matched  
than before the upgrade and adjustment. Lux lenses focus fine as before.

  I would like to report on my impressions of the upgrade. First, the  
new shutter is quieter than the 1/8000 one and there may be less  
shudder when taking a picture which could mean sharper pictures at  
lower handheld shutter speeds - but I haven't yet had a chance to test  
this out. I was rarely concerned about the noise of the original  
shutter - only in silent and empty churches in Europe did I notice its  
clacking - and not many churches were empty and therefore silent.

The big improvement is the viewfinder brightlines which are now  
optimized for 2 meters instead of 0.7meters. I have shot about 100  
pictures since getting the camera back and the viewfinder accuracy is  
much improved. For me this is a Big Deal. Switching between the Nikon  
D700 (95% viewfinder) and the old viewfinder of the M8 was frustrating  
because the brightlines outlined the picture taken by the M8 in a much  
less accurate fashion than the D700.

The scratch resistant LCD is a kind of silly upgrade - a $10 plastic  
screen protector from Sony will accomplish the same protection and can  
be replaced when it gets scratched. I may cover the scratch resistant  
LCD with one of those anyway.

In sum, for me, the upgrade which makes the biggest sense is the  
upgrade of the view finder bright lines. I really wonder what Leica  
was thinking of when they optimized the finder at 0.7 meters.
Now I have to decide whether to sell the 90 Cron or send it to Solms  
for further adjusting so I am not really far ahead and my pocket book  
is quite a bit lighter, (the full meal deal of upgrades is US$1807 in  
Hong Kong)
Merry Christmas to me.
Cheers
Howard
PS: If anyone is interested in a back focusing 90 Cron APO (which  
works fine on film Leicas) please email me privately and we'll talk.  
Who knows maybe it will work fine on your M8??
