Rich, that makes sense. One of the nice things about this game is that there are so many different styles of lens to fit everyone's different tastes. I really like the look I see in my shots and think I see in your scans (though it is always difficult to be certain... ) but I can honestly understand your hesitation. Out of curiosity, have you considered a shootout between this Tessar and your 50/1.5 Sonnar? I realize, there is a small bit 🙂 of speed difference but put the lenses in similar extreams for thier designs and see how they fare from that perspective? I think it might be illuminating... but then, I'm a known Tessar bigot, so take the suggestion for what it's worth... 😀
