i have the canon 15mm fisheye picked it up used on ebay for $650 a couple of weeks ago. i have used the 8-15L my photo buddy has one and i was going to get one my self but, i couldn't part with the price of entry for the L zoom just to expensive for a specialized lens for occasional use so i went for the alternative, wonderful lens, sharp at f/2.8, fun to use and reasonably cheap, recommended
So....can you borrow your bud's Zoom and give us a side-by-side at 15mm f/4 with a 100% crop for comparison???!!!!???!!!!?
Actually ...I don't really need it...I am very happy with my Canon 15mm f/2.8..paid same price as you..bought it new just as the 8-15mm zoom hit the market. Its a cool lens, and perfect for "my" needs!!!!!
everybody body wants to pixel peep, yes the L is better at f/4 but not at f/2.8 it's a better lens all round but only slightly better for double the price its not twice as good, it's my only non L lens but as infared said "it's a cool lens" I concur.
