I just noticed a difference in the votings of

mechanical quality between the Nikon FF test and the

Canon FF test (4 stars vs. 4.5 stars) ...



... Question ... is this just a personal preference of the tester,

or is the Canon-version indeed differently built?



Just a thought ... Rainer



PS: BTW ... thanks very much for the test. A very interesting lens indeed.

The Nikon version offers an automatic aperture as well as focus confirmation. That's certainly worth the extra half point over the Canon variant.
