Tokina 50-135mm V Canon 17-55mm Colour Reproduction

Gareth, that's "Big GA" over at dpreview, got my curiosity aroused when he asked about potential colour shifts when using the Tokina 50-135mm on his Nikon's as he was considering buying the Tokina.

Well I couldn't do the comparison on a Nikon but was interested enough to see how the Tokina compared with my Canon glass on the 40D. This comparison is only a very quick look to give a general idea....so AP was used with ISO400 and 1/125@ F5.6 for the test shots and ACR was used for the conversions on default settings. The first shot below is the 17-55mm F2.8 Canon lens.

And a couple of crops first up the Canon 17-55mm

I'll leave you to draw your own conclusions but for me there's not much in it with the Tokina maybe being a bit cooler.
