K&F Concept Lens Mount Adapter,TAMRON-AI Tamron Lens to Nikon Camera, for Nikon D7100, D7000, D5200, D5100, D3100, D300, D300S, D200, D100, D50, D60, D70, D80, D90, D40, D40x, N70s, D80, D800, D800e, D4, D3, D2, D1

Although I had to send it back I still consider it well made. It would not work with my tamaron lens, but the lens is nearly 50 years old so I wasn’t completely surprised

Good fit with Tamron Adaptall lenses, but bear in mind you won't be able to use your Nikon DSLR with AF. I could only use my older Tamron lenses in Manual mode, meaning no autometering, no AF. Also bear in mind older lenses are 35mm format, while DSLRs are 24mm.

Just a piece of plastic. Would have liked it to be made of metal. However, it has made my old Tamron zoom useful way past its age.

UPDATE: Since my D750 camera was not on the list for this adapter, I wrote to you earlier and you clarified that it would work. Yes, it WILL connect the lens, but the aperture ring won't move. I have two old Tamron lenses that date back to the 1970's and used on my Pentax. I tested my two lenses and I have to return it.

This adaptor was really useful.I purchased a Tamron 500mm f8 lens from eBay and I needed it to work on my Nikon D810. This adaptor did the trick, I was able to get super cool shots!
