The 50-230 is an excellent lens, Tony. If I went back to Fuji from Sony I'd pick one of those up like a shot.I've been looking at telephoto lenses of late. I didn't want huge and expensive, but I did want to be able to pull in the view at times. I found a great deal on a brand new Fuji XC 50-230mm II, and a black one, at that. Balance on the X-T1 is excellent, and it is lighter and shorter than the Vivitar 70-150 I've been using, while giving me 50% more reach. I think my days of using adapted lenses on digital are coming to an end, although I'll still use MF lenses with film.
