Lens Description: This lens establishes a new benchmark as a standard lens, extending from a wide 28mm all the way to 105mm telephoto, all with a fast constant f/2.8 maximum aperture. The use of four large diameter aspherical elements and three LD glass elements reduces various aberrations while minimizing the fall-off of light at the corners. Tamron\'s Integrated-Focusing Cam system, Internal Focusing system and Triple-Cam zoom system all combine to permit a body that at the 28mm zoom position is very compact, with excellent optical performance.

Mine is not focusing properly, even manually. Have been searching where I can get it repaired, any suggestions?
I got this lens from an auction sale with a Konica mount. I switched it to a Nikon mount and use it on my Nikon D750. Nearly every review complains about the lack of sharpness. I do not encounter this. I use it in my studio under bright lighting for product shots and it works wonderfully well giving really nice images but with a look almost like film. I would not want to use this outside for wild life or landscape work etc but as a studio lens I love it. I give it 4 out of 5 stars.
