Even though I did a lens test and compared the biogon side by side to my cv skopar p2 and found the skopar to be a great lens that can hold its own to the biogon I keep thinking back to the biogon, and despite the fact that I love the ergonomics of the leica 35 cron asph over the biogon I still find myself coming back to the biogon. Soon I will be adding a planar to my kit, and im seriously considering selling my voigtlander lens and adding the biogon...its just I dont use 35 as much as I used 50....maybe later.....
