I won't forget it, don't worry..
There was some method to my madness in selling the Bigma. I bought it in November and barely used it because I found it too heavy to carry around. With practice I probably could have gotten better with it but I'm not that patient. Instead someone in Canada is now enjoying it (unless he sold it too).
The money paid for my AF1.7x adapter (it's not a TC, remember) and the better part of my DFA100 f2.8 WR. The adapter with my DA*300 gets me to the 500mm range at about the same wide open aperture as the bigma and it's less than half the weight. Haven't tried it on any critters yet but it does a pretty fair job for those distant candid shots.
