why are they so cheap? Compared to Nikon, the sigma is half the price
Does this mean....VR and slighty bigger max apperture costs $600?
Well...ok, but does the build quality differ by miles?:think:
actually its still the same... sigma got their APO, tokina i dono, tamron got LD... its just that people always mention the good about N/C but not 3rd partyFor Canon, it's the UD and fluorite in the Ls. Nikon ones should be their ED.
build quality not really differ by miles, in fact 3rd party makers like tokina make SUPERB BUILT lens... by superb it means it can match or win nikon or canon.
99% of the time, the MAIN difference is in the quality of the image. somehow canon and nikon got some pretty good chemical or watever that they use to make their lens so that they give very good colour, contrast and sharpness.
actually going by today, 3rd party optic ain't really inferior to the "original" equiv... in fact some even surpass tho some are not as good...Agree with what u mentioned about Tokina. Although i even haven't touch one yet, I am really impressed by the physical outlook of Tokina lenses. If they bother to have such nice, solid design, I think their optics must be good too...

Image quality and build quality - a world of a differemce.
VR is also really, really useful.
finally, who would want to shoot at 6.3 at 200mm? 5.6 is really dark already and without VR too! You will get really difficult to control shots!
it depends alot on the lens, there are some APO lens that are superb like 300-800, 70-300, 50-500, 50-150... etc. all of them are APO lenses and some of the quality even surpass nikon/canon equiv if there is any... :bsmilie:Honestly speaking i do not find Sigma's APO fantastic. Tamron's LD is not bad but still lacks the quality from Canon and Nikon.
