This could be for lenses, bodies or anything really, but is there anything that was in your kit bag you regret selling and why so?
For me, it was my 80-200mm f2.8L (the black coloured predecessor to the 70-200 f2.8L). I got it pretty cheap second hand, it was in great condition, the IQ was excellent and it was built like a tank, but the combination of a very noisy motor, the edges of images always needing slight trimming and people asking "What decade did that come from?" led me to sell it and get a 70-200 F2.8L. I dont regret getting the new lens, but I do regret selling the old lens. I got a good price for it, but it would have been a great back up to keep for days where I'm shooting somewhere old, dank or dirty and I worry about the nice shiny gear. In the future, if I have a good lens I can use as back up I won't sell so quickly.
Any similar feelings amongst you all?
