In Pentax world, this shows easily in K vs M lenses, where the K lenses are often optically better than the corresponding M lens. It shows the most in Cinema lenses, where even the primes are 3.5 Kg monsters... but their image quality is worth their weight in gold (and the price almost as well <g>). It's funny how much bashing is there still around Leicas. Either big pro or big against... Frantisek
