I'd been considering getting rid of either the 250mm lens or the 2x teleconverter to simplify my camera kit a little bit.
However, I got to use both -at the same time- very recently. I made a few images of a power plan in Michigan City from the nearby Indiana Dunes, and the combination of the long lens plus the teleconverter (500mm, or 275mm in full frame equivalent) proved to be very useful. I wouldn't be able to catpure it without them.
So I'm back to the drawing board and considering keeping both for situations like this, where I definitely need that focal length.
