I wanted to provide some detail about my experiences with this new lens, and it's performance in my day to day photography work. If you had asked me 15 years ago, I would have been very hard pressed to recommend a Tamron Lens, but with some work and time, they have managed to sell me on this...
Solid Construction: OK, we hear a lot about "plastic" feel and less than rugged construction; I think we will have to get used to this construction method as it will be the norm going forward.
Auto Focus Lock: OK here is where I will complain about Tamron's way of doing things; On other AF lenses that I have from Nikon, you can turn the Auto-Focus Ring, while the lens is set to Auto and it freely turns without causing any potential damage to the lens.
