The 28-70 is a really nice lens and tempting. How about vignetting at the wide end (1.5 crop) with that hood?

There doesn't appear to be any (additional) vignetting with a 1.5 crop sensor when using the hood vs not using the hood. I just tried to confirm this by taking a shot of an evenly illuminated wall both with and without the hood at 28mm, f/2.8. Neither shot showed much visible vignetting. So I opened them in Photoshop and played played with the levels to try and bring out the differences between the corners and the center. In both shots the corners are a little bit darker (I'm not sure how to quantify the amount, the range from darkest to lightest was about 15-20 steps out of 256), but it is pretty much the same amount both with an without the hood. That's why I don't think the hood is adding any vignetting to the lens itself.

On a FF/film body you can see right away in the viewfinder that the corners are significantly darkened. This is certainly not a suitable hood for film. That said, the hood itself is a great replacement. It's really robust, attaches perfectly to the lens and even reverses well. And for APS-c, it probably provides even better protection than the original.
