There is little doubt in his mind nor mine. At 11:00 AM 02/11/2005 -0800, you wrote: >At 7:24 PM -0500 2/10/05, William G. Lamb, III wrote: >>Carl, >> >>Frank's summary was pretty good.

In bright light combined with >>conditions of high humidity it can vignette. I'd imagine that you are correct as far as the theory goes, and I'm not a scientist nor am I an engineer. In the REAL world, the 35/f2 ASPH exhibits this vignetting noticeably in the conditions I describe. It does not otherwise. Several other users I know have experienced the same characteristic. Care to account for this phenomenon theoretically? It is the one real flaw of the lens, and both mine exhibit it. Do you happen to have one of these, or are you just guessing? Pardon me for asking, but there is no end of guessing, idle and uninformed speculation, unrestrained whinging and moaning and the like on the LUG. Generally I refrain from comment because the most frequent posters claim to rarely use a Leica anymore anyway, and there would be little point. The gent who asked the question actually appears to want to buy and use a Leica lens on a Leica.
