hi guys So, after debating between the sigma 10-20mm and the ultra-rare tokina 11-16mm ... i dived on the latter one. It is on a nation-wide backordered and somehow someone linked me to Arlington Camera. They are dedicated and really awesome, Melanie (their's e-commerce leader) entered me into their waitlist and they received 5 of those lens from Tokina 3 weeks ago I got one and I am very very happy about it. Considering even B&H, Adorama etc still in backordered, kudos to Arlington. I tried the AF mode on D60, it just doesn't work but the manual didn't explained further. I just learnt from the staff that the Tokina won't work on D40, D40x, D60 .. not sure on what reasons, but it does works on higher ends Nikon, like D300 etc. Woohoo .. something I had no idea about when purchasing, anyone ever know about this prior?
