The Tamron SP 15-30mm f/2.8 Di VC USD is the first fast ultrawide zoom lens for full frame cameras to offer built-in image stabilization. It's slightly wider than the closest offerings from Canon (16-35/2.8) and Nikon (17-35/2.8) but not quite as long when zoomed out.

When it comes to creating excellent wide-angle photos and giving the most bang for the buck to photographers, Tamron seems to have the formula almost perfect. With great colors, excellent sharpness, and a very versatile focal length range, a photographer would be thrilled to have the Tamron 15-30mm...

The Tamron SP 15-30mm f/2.8 Di VC USD ($1,199) couldn't have been an easy lens to design. It covers an extremely wide angle of view, has a maximum f/2.8 aperture, zooms, and is optically stabilized to boot.

Sharp; Optically stabilized; Maximum f/2.8 aperture throughout zoom range; Integrated lens hood; Ultra-wide field of view; Close focus capability; Available for Canon, Nikon, and Sony systems

Lots of distortion; Bulky; No filter support; Some flare issues

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...

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

A very impressive lens, producing a high quality image wide open at all focal lengths. The lens appears to be a bit sharper at shorter focal lengths than at the long end, but the difference is minor.

Exceptional sharpness; high build quality; good VR; fast and bright; wide open image quality excellent

weight; size

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.

#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 thought that Tamron had outdone itself first with its 70-300mm lens and then with the 24-70mm f/2.8 and 90mm f/2.8 Macro lenses: all bearing the SP (super performance), VC (vibration compensation), Di (digitally integrated primarily for full-frame sensors), and USD (ultrasonic silent drive)...
