Image quality, flare, distortion and vignetting test results along with some product photos have been added to the Tamron 150-600mm f/5-6.3 Di VC USD Lens Review page.
The Tamron 150-600 VC Lens vs. Canon 100-400mm IS Lens comparison is what many of us have been waiting for.
Especially for the price, I think that you are going to be very pleased with the image quality this lens delivers. I hope to have a full review of this lens completed in the near future.
