[rollei_list] Re: OT / prove it !

This reads so provocative and argumentative . . . almost grasping at 
anything disputable . . . by seizing on an obtuse view of only a portion of 
Eric's statement out of context . . . a view that has no real value in 
practical photographic work . . . and completely ignoring the intent 
expressed in its entirety.

Yes, of course, _in_general_ 35mm will yield greater lpmm on 
film.  However, you choose to completely ignore that fact that in making 
the same size print, a larger piece of film requires less enlargement, and 
that _in_general_ the enlargement required decreases at a greater rate as 
format size increases than the reduction in lpmm.  The net effect is 
exactly what Eric expressed in his complete statement; larger format 
potentially yields greater "sharpness" in a print or projection.

This is presumptive that the optics in use are comparable and that the same 
level of care is taken in making the photograph on the film (hence the 
careful "_in_general_" caveat).  One could easily cite many anecdotal 
examples of just the opposite by carefully crafting an unfair comparison to 
achieve that result.
