>>4004014I'm that anon you asked. I have an X-E2 as well and only got the X-T4 recently and kept my lenses. I got the 50-230 mm cheap second hand, and I made it sound worse than it is I guess. It really is a great lense, it sometimes misses autofocus (which is very annoying when it happens, because you'll probably only realize it when you get home), and the vignetting is a rare occurance, other than that, it makes pretty pictures and I'm very happy with it.
>>4004017The 50-230 really shines with the X-T4 instead of my X-E2 though, IBIS makes A LOT of difference on higher focal lengths. It isn't as bad a combo as you might think :)
