i just came back from TK...
great... wat the heck are tamron sg thinking of?? only 6 were brought into singapore as of 6pm today. TK has 1 canon EF mount. and yes, its ard $700.
i tried it out on the 30D, courtesy of TK. overall size, very similar to my tamron 17-35. focusing is surprisingly fast on the 30D - i dare say faster than my 17-35. and another surprising thing for a tamron - its actually quite quiet. i've used a few tamrons b4 and this is an improvement over the earlier tamrons i've used and/or owned.
i couldn't take back home any images to pixel-peep cos i was using TK's cam and CF card. but on the 30D LCD and zooming in, the test images were reasonably sharp at f2.8. at least, the copy i was test is sharp. just dun go compare it agst ur L-lenses lah... of course.
overall feel? worth buying if u not too keen on getting a L-lens. now... if only they have a nikon-AFD mount at TK... :think:
