Leica Guide: 16-18-21mm f/4 Tri-Elmar-M ASPH
Just published in my Guide to Leica is a evaluation of the Leica 16-18-21mm f/4 Tri-Elmar-M ASPH at its 3 settings of 16mm, 18mm, 21mm.
My goal in this comparison was to offer perspective on focal length, as well as image quality evaluation, and some thoughts on the 21/3.4 Super-Elmar-M and 18/3.8 Super-Elmar-M alternatives.
