Tamron 85-210mm f/4.5 Adaptall model Z-210

Cheap and good alternative to 1.4s. A tremendous lens. You give up 60% of 1 stop of light fro what a 1.4 give you. That's really not much to complain about. The lens is excellent in all ways I have tested it. It focuses well, the Bokeh is nice, it's super sharp and the VR works reasonably well. These are a completely viable alternative to the pricey 1.4 offerings. I have no qualms about recommending it and I've owned a lot of nice 85 1.4 and even the Canon 85 1.2.

It's one of the best for the D810 It's not as huge and heavy as the Sigma. It's nearly as good at dxomark. It takes affordable 67mm filters. Beautiful bokeh and photos.

Fast, sharp, affordable, and versatile lens. The only portrait lens on the market with built-in VR. Very sharp, great for low-light portrait work, and most of all, affordable!
