RE: [Leica] What do you do with Leica Projectors

[Alan Ball <AlanBall@csi.com>]

Lucian,

Thanks a million for your explanations. Seems reasonable to me. 
Unfortunately.

Regarding the pop v. tightening issue: I feel that 'popping' tightens the 
slide by adding that extra curvature....that is nicely managed by the CF 
Colorplan I have on the P600. My slides are sharp corner to corner only 
after the 'pop' occurs. Before the 'pop', I have to compromise and manually 
decide which part of the slide must be 100pct focused. Which is a really 
annoying process for the viewers...

Will think about trading in as soon as I can get my hands on a 2002 for 
trial (with my slides in my flat).

Thanks again,

Alan
