One of the best lens you can get for an a mount , a99ii is my camera and this lens is tack sharp wide open, use it for landscape and other work, thanks Tamron for Filing the need of A mount users. Its a big lens and heavy if your hauling it around all day long but well worth the asking price.

I am beyond impressed. It is a rather large lens, physically speaking. It uses more plastic than I'd like. But, and this is a big but for me, the quality of the images are at the very least as good as and in some areas better, in my opinion, than the legendary Nikon 14-24 and a bit longer reach too...

Pros: Very Sharp at f/2.8 15mm across the lens Best 15-30 mm zoom for the price $1,199 Nice to have VC if you need it Like having the extra zoom 24-30 6 year warranty Feels like a very solid lens Cons: Maybe a bit heavy for some people No filter kit yet Doesn't say Nikon on it, a problem for some.

This lens is really great. Its lighter than its competitors, its got stabilization and great image quality. But its not without some cons, whether it changes your mind about buying it, is up to you. But, at f2.8, its soft.

#sweepstakes - First, let me say I love all of my Tamron lenses, and the 15-30mm has been a great addition. I've had it for about 2 months now, and I've used it almost every time I've gone out.

I use it every day for interior and architectural photography. There is no better lens for my work at the moment. Picture quality is unbeatable so you have to get used to the size of it.

I have had this lens now for slightly over a year before I decided to write this review in order to be honest as I can. Now at this point when I read some of the bad reviews about sharpness, I can only assume that they got a a flawed version as I found my version was at its sharpest from F4 to F13.

Have used this product now for a week plus. The results are amazing. Captures full breadth of the scenes. Sharp corner to corner. Am getting good results so far.

Love this lense. Very sharp in the corners and the image stabilization is incredible. I only wish it was a bit lighter and could take filters, but other than that I can't complain about the results

My favorite lens with an amazingly sharp picture, as I wanted. Funny enough price for quality equipment

Doubtful stabilizer; To be honest, his work is almost not visible; If rapid change in focal length gives off an unpleasant \"plastic\" sound

A very sharp throughout the entire range, specific features in the wide-angle, 15 to 22 mm; Chromatic aberrations are minimal and easy to ruling in DxO; Perfect lens for interior and - especially landscapes; Excellent detail, qualitative study of overexposed parts in the sky.
