It will have to be good ---

[I @ M]

Tokina have released their version of the 70-200 F/4 VR lens (http://www.tokinalens.com/tokina/products/atxprofx/atx70200mmf4fxvcms/) and going by the pictures on the site it comes with a tripod foot but at only $300.00 less (http://www.bhphotovideo.com/c/product/1054592-REG/tokina_at_x_70_200mm_for_4.html) than the excellent Nikon version it will have to be very very very good to compete.

....... it will have to be very very very good to compete.

(I think) It will have to be a lot better to compete!

$300 difference is not enough to warrant the purchase of a non branded item(I reckon).
If it's astoundingly better AND cheaper then it has a chance.

IIRC the Nikon comes without the tripod foot, which costs about $200-ish itself .. so you'd want to compare like with like.

So is that $300 difference for the barefooted Nikon lens, or Nikon version + the extra for the foot?

Looking into it further the Tokina doesn't list the tripod foot as a standard inclusion and it is heavier than the Nikon. I think that there will have to be some considerable street price adjustment very quickly for it to sell a single copy.
