[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I added the SUPER ELMAR-M 1:3,4/21mm ASPH to the comparison stack, below: http://www.paulroark.com/Loxia-v-Leica-21-f28-SEM.tif No doubt the SEM is the sharpest and smallest modern 21. I have the ELMAR-M 24 mm f/3.8 ASPH, which I use as my "reference" wide angle on an M9. The Loxia, at f/2.8, however is faster and has a good 3/4 stop less vignetting/light falloff. I used the Biogon C 21mm on the M9 -- for B&W. (It is not appropriate for color shooting due to bad magenta color at the edges.) It's sharp, but the vignetting was significant -- about like the SEM 21. I found heavily "red filtered" (in Photoshop) blue skies got noticeably more grainy at the edges with the M9. So, that light falloff issue is a relevant factor in the calculus. The WATE is my only good superwide that will fit on the Sony. More speed and better wide open performance is what I'm interested in with the Loxia 21. We'll see. If it's a turkey, it'll be returned. It will not be shipped until December.
