This is an editorial. A few years ago I bought one of those cheap Vivitar .43x auxillary lenses. I wanted it to fit on my Tokina 28-70mm f/3.5 lens (which it did perfectly without an adapter). The reason I'm writing this is that I am finally very impressed with the versatility this lens gives me.

It comes in two parts. There is a 2.5x (focusing at about 4 cm) close-up lens at the back and the convex wide-angle converter at the front. You have to use both parts screwed together to get the wide angle conversion.

I was recently given a used Tokina AT-X 50-200 mm lens. I had never heard of that brand and haven't been able to find anything about it on the internet. It was recommended that I purchase a Fotodiox Adaptor (Nikon F to Pentax K). It doesn't fit -- any suggestions would be appreciated. I am using a Nikon D60.

Why would you buy the adapter? The Nikon F mount ought to fit the D60. Tokina is a respectable 3rd party lens maker.
