Ok, it arrived today. Aaaaand, it's going back. The focusing helicoids are grinding and occasionally slipping when I try to manually focus. Interestingly in AF it seems fine, but slow.
There was no mention of this in the rating - for UGLY they say the outside is beat up and the glass has flaws. The glass is completely clean, and the casing would be too if I cleaned off all the packing tape/scotch tape residue that for some reason is all over the lens.
I have no idea why someone would tape up the lens (it arrived with the tape removed, but the residue there which is why I think it was rated UGLY. KEH just didn't want to clean it). The zoom does not slip, so it wasn't to hold that.
Of note, even if this lens was fine I would send it back. I knew it was going to be big and heavy, but after 10 minutes of walking around with it testing focus etc, it just was not fun to use anymore. It is stupid heavy and bulky and unbalances the camera.
I get it for studio use, but even (especially?) then you would have the luxury of picking the correct prime lens. A 50mm prime is coming to replace this.
And so my UGLY KeH experiment ends!
