Well, I guess, "S" and "L" just stand for short lenses versus Long lenses, but the "L" converters themselves are quite "Long" too :-) >The "snout" to which you refer- is that cause for incompatibility >with certain lenses of a more conventional focal length, like a 80-200? > Yes, you have to be very carefull when trying it on a new lens, measure first, then measure again! >Are there any differences in brightness between the two? I am not sure, I have not seen a Pentax 2x S, I do know the "L" ones are brighter (larger lens diameter) than most other converters I have seen. I have the 1.4 and 2x APO AF converters by Sigma, and they are visibly smaller and cause vignetting on long lenses using larger apertures. (otherwise they are very good) Regards, JvW ------------------------------------------------------------------ Jan van Wijk; http://www.dfsee.com/gallery - This message is from the Pentax-Discuss Mail List.
