Thanks for the responses! My 110 is average, but the 65 MLA is tack sharp, I was never pleased with the 180, so I sold it and bought the 140 which I'm embarrassed to say haven't used yet even though I've had it for 4 months. I usually shoot a few stops down from open, but I'm really looking for a good SHARP wide angle like a 50 (or my 65) that I can use fully stopped down for maximum DOF.
