I think it's a dodgy counterfeit one. All the writing on it is backwards.
Blimey! Perhaps JB's were selling those Bali knockoffs - nonac!
Congrats! You're gonna have tons of fun with that lens
From what I can see with those shots your on a winner,my Nikon 50mm takes super shots and a really great pano lens.
My Gear - Canon 450D, 7D, 60D. Lens - EF-100mm f/2.8L Macro, EF 100-400mm f/4.5-5.6L IS USM, EF 400 5.6L, EF 24-105mm 1:4 L IS USM, EF-S 10-22mm 1:3.5-4.5 USM, kit lens, twin flash, 580 Flash, monopod and tripod. Lots to learn.
Who's been a good boy?
Don't you get the filter for your largest lens and use step down(up) rings? Should work, though ask in gear talk forum, 'spose.
