Canon 5Dmkii

The new Tamron's 15-35mm f2.8 Ultra-Wide Zoom lens has now shipped and I've been lucky enough to get my hands on one. This is the latest and greatest from Tamron and is designed to feed the hungry 50 megapixels on the new Canon 5Ds and other high megapixel cameras. To see how true this claim is, I've spent the last few days testing this lens with both the Canon 5Dmkii and the Sony A7r with the metabones MKIII adapter.
