Surprisingly Pleasant
I ordered this lens as the wide end adjunct to my f2.8 lenses (100, 135, 28 -70 & 70-200mm). I am anticipating a full-frame in the future and I still have a couple of very nice 35mm cameras so I passed on the Tamron digital only 17-50 f2.8. I was extremely pleased with my first "real world" low light test of this lens. You see I shoot billiards (pool) competitiions which is low artificial light and absolutely no FLASH. This lens handled the challenge with swift Auto Focus and sharp contrasty images. The minimum focus distance is amazing and an unexpect bonus. This lens has gotten me to wonder if the Tamron 28-75 f2.8 is equal or better than. So, I am looking to find out. It couldn't hurt having two great lenses in that range?
