I just noticed that the 35 has a USB dock for AF adjust & firmware updates. That's very interesting.

It only come with One Year Limited Warranty
For Canon users, the only reason I could see going the Tamron route on both of those lenses is if you wanted their 6-year warranty...otherwise, price wise, they aren't really that much cheaper than the Canon L version, especially the Macro.
