I certainly agree about 4 glass lenses and flare suppression. I do a lot of shooting towards and into the sun as well.Originally Posted by David H. Bebbington
The original Voigtlander Skopars and Color-Skopars were classic 4 glass Tessar designs. The current Color-Skopars in Leica mount are indeed excellent lenses, but I am not aware of any that are 4 glass designs. For example, my 21mm f4 Color-Skopar is an 8 element 6 group design.
