So different to the bigger brothers. Much, much easier to reduce aberrations at the more modest maximum aperture, of course, as you say. The concept looks good, doesn't it? A very compact lens set. Compact and reasonably affordable is their raison d'?tre. Good for Leica and all rangefinder folks. Who would have thought that we would be seeing these new compact M lenses from Leica and Zeiss designs? For this market, if the prices are similar (to the ZM lenses made by Cosina) I can see these having bonus desirability with the Made in Germany tag and that's irrespective of any actual performance comparisons. Cheers Hoppy -----Original Message----- Subject: Re: [Leica] New Summarit lenses Isn't that essentially what Erwin said they did with the 40mm 2.4 Summarit for the Minilux? It performs well because wide open, its already a half stop down, if that's not an oxy-moron phrase!
