[QUOTE="Fortkentdad, post: 618653, member: 24285"] Not big into reviews and I know there are more scientific ways to do this. Testing is done with a D7100 and D610 After much trial and error decided that a minus one adjustment produced the best focus - this was done with a row of AA batteries as my 'test chart'. Set of five focus on the middle one, then adjust to get the middle one the best. Tested camera about 18" away (minimum focus is about one foot. Tests were all done hand held. I did some comparisons to the lens I wanted to upgrade from - an older (as in designed for film I read) Tamron 17-35 2.8-4 It is the SP AF Di LD (IF) version (they ran out of room to put on more initials I think) Over all the lens works well. Focus is fast enough - not setting speed records but OK. Slight noise, not silent by any means but not too loud. The push - pull focus ringy thingy is not a selling feature as much as Tokina would like to say it is. I don't like it. It works but meh. Manual focus is good. It was when I could manual focus better than the auto-focus that I decided that I should try fine tuning the AF. It is a snug mount - I think it is the weather seal rubber that makes it a tight to mount. It is the tightest mounting lens I've owned. Must be a real good seal. Good weight in my hands - feels solid enough. [ATTACH=CONFIG]252921._xfImport[/ATTACH] [/QUOTE]
