Thanks PC. I do love my Tamron 90. It is the candle I hold all my lenses too, and it's difficult to keep up. I often find my self thinking I need an 85 1.8, but then I remember the 90 is pretty damn good. Unfortunately I would say I was probably 12-18 inches from the dragon fly and maybe 8-12 inches from the smaller Damsel fly. I say unfortunately since you will need to stalk your pray to get them full frame like this:) I would love a little more working distance, but on the flip side I would also love a little more DOF. So in the end a 90mm macro is well a good compromise. In the interim, the 85 is also a very sharp lens, maybe adding a diopter would help quell the lusting? I never tested my lens for sharpness wide open and would speculate that your 85 will play better at 2.8-4 then mine. I usually shoot with it stopped down and sometimes all the way to f40. I think about adding a Diopter to my 300f4 to get me the working distance I sometimes need. Had it been on the camera, it would have made for a good choice in these shots. There is ALWAYS one more thing to get:)
