>>2849257I have that lens. It;s got great image quality but it has a slow autofocus motor in my opinion. The time to autofocus in sealed room with one 60w bulb is ~0.5 seconds. In sunlight it's mostly instant but sometimes has the same 0.5 delay.
Ironically the camera focuses FASTER when it isn't in performance mode which is fucking weird.
The motor is also strangely loud compared to the other lenses, kinda defeats the purpose of the the eshutter. It's loud for room level noise, outside you obviously wouldn't hear it.
Other than that it's not bad, here is a sample from my xt10
