Yeah... the 50-140. Like the Pentax 50-135 and a few 70-200's that I've had... all excellent lenses that I may have used a half-dozen times tops when I had them. I basically shoot 100mm or under - or need something very long for wildlife or motorsport.I've recently found myself in kind of a bad spot. Most likely I'm going to put the 50-140 I bought during the rebates up for sale. The bad part is will be at a loss. But, I find I am not going out and shooting any musicians. Nor do I feel the desire to. The band made up of good friends of mine I will still go see. I can shoot with the 16-55, or mid length prime. I do have a battery grip and hand grip for the X-T3 I acquired cheap enough that I can sell and get the money back out of which will help with the loss on the 50-140.
The other down side for a former gear ho. Is that there are not any lenses I'm lusting after. This may turn into just downsizing.
