I mostly shoot M43 these days [EM1 ii] but there is a spare X-T2 in the house and my wife has an X-T4 and lenses.
Anyway, I was looking hard for a medium tele zoom, particularly at the Oly 40-150 f/4 when it occurred to me that the 50-200 was pretty identical in focal range, aperture and size [heavier though] and available second hand for a lot less dough.
So.....picked up what looks like a nice example, for under $500 AUD.
It will be fun to get back to shooting with a Fuji sometimes!
