Excellent images, Bob! Love the G90 shot...I just picked one up myself to replace my Contax Planar 100/2 and so far I'm impressed!!
Also on this page...Old Raven, Helena, Frogfish, Ronny, Michiel, LightandMotion, and Jack...All incredible images! Jack, the 35 Biogon shot stopped down is impressive.
Helena...Love your first examples with the 18/4...equally impressive!
