Tamron SP AF 90mm F/2.8 Di Macro

Great Quality dont have much diference in quality for Nikon 105 2.8 VR grat lens, the only problem is a little slow the AF Problems: Slow AF

I've been using this lens for 2 years and absolutely love the optical quality. It is extremely sharp and has a beautiful bokeh to it. The focal length works very well on a DX (APS-C) camera. The only complaint I have is that the AF: you can watch grass grow in the time it takes to get a focus lock! It's noisy, slow, and does a lot of hunting & searching. I used this lens as a budget portrait lens before I could afford an 85 1.4 and found it to work very well (outside of the AF speed!). ...

I had this lens for awhile and this lens never let me down. I would say value for money compare to Nikon, Canon Macro lens. CA is noticeable when zoom in (very close). Picture wise is sharp tick but AF is slow as the lens extend out.
