Tamron SP 15-30mm MTF charts (beats the much more expensive Nikon).

We have first info about the new Tamron SP 15-30mm A-mount lens. Image samples can be seen at DC.watch. And there is also a full MTF chart posted by BlogNaver (found via Dicahub).

The MTF resolution is impressive even at widest aperture. And also on the telephoto end the resolution remains high. By comparison here is the MTF chart of the AF-S Nikkor 14-24mm F2.8G ED lens:

The Tamron has no official US price yet but it’s rumored to be around $1,500. So much cheaper than the Nikon. The Tamron A-mount lens is listed at BHphoto (Click here) and should be available soon for preorder.
