No use in even posting samples. I think my good copy is now bad. When I push the barrel up the upper half gets sharp again, so clearly the wobble is hurting sharpness. I think the build quality on this lens simply awful. I've tried very hard to baby this lens, but it should be able to withstand a knock or two. I guess I send in my bad copy and have CRIS tighten that and realign it. I hate spending anymore money on this stupid lens, but the range is nice and the rendering and sharpness are both superb when your copy is optically good. I dunno. I mean I can spend $180 or so at CRIS and have the same issue 6 months-1 year down the road. I need something between the 16-40 range and this lens was a seemingly perfect fit. The 17-70 isn't great at the wide end IMO and the 1mm makes a big difference. The 16-50/2.8 is just too much money and I don't need the speed enough to justify spending $1000. Not when I could buy a couple of limiteds for that....If this lens is this fragile, its gotta be the flimsiest zoom I have ever used and that's saying something. Even my el cheapo 28-80 is better built. I really don't know what to do. The 2nd copy was a LN- grade from KEH. It seemed ok optically at first, but seems worse now than before. I liked the lens enough that I needed another copy to replace the first while I decided what to do with it and didn't want it missing. My 18-55 mk1 just doesn't cut it really and isn't very usable at open apertures.
