I bought a new Nikon D50, a Sigma 70-200 2.8 AF-D EX APO IF HSM and a Tamron 2x AF-S 7 element teleconverter in the beginning of December. I wanted to try a second DSLR system, and in case I liked it, build a small Nikon outfit in parallel with the Pentax stuff I have. I also had a Nikkor 18-70 AF-S on loan for a pair of weeks. Yesterday I sold the Sigma 70-200 2.8, and I sold the D50 and the Tamron teleconverter nearly a month ago. In my short experience with Nikon mount ring motor lenses, they don't focus any faster than the Pentax screwdriver AF lenses I have. I have also tried those lenses on a D200, by the way. They are almost very silent, though, and that is a nice thing.
