BTW, the Tamron 55-200 and the Sony 55-200 are the same lens with a couple minor distinctions.
- The Sony SAL-55200/2 has it's own SAM AF motor, while the Tamron works off the AF motor in the camera body.
- The Tamron is cheaper and has a longer warranty.
Of those two, which would you say would focus faster, and which would have better image quality?
