Hi
Are you switching the Macro switch on the lens. This switch can only be operated when the lens is set 180mm or greater.
You should find this will put it right for you. The telephoto ring can be found to be a little difficult to turn manually to set the lens to 180mm ++.
Hope this helps.

Thanks Bramlela, yes I have the setting on the lense set to macro but when I try to focus the lense just zooms in and out and does not focus to the subject.

most lenses that have a macro switch, like my vivitar S1 70-210 F3.7 change the way they work when in macro mode, focusing is very limited in function, and the zoom function becomes the way to focus.

Note you usually have a restricted range of focus in this mode between a few inches and a few feet, but this should be in the documentation.

forget about AF. put the lens in macro mode and focus to infinity and move the cam in and out till you get focus. you should be about 3' away from the subject at 300mm

Interesting. Using the "macro" setting on the dial apparently fixed whatever the problem was? What was the dial set at before?

The camera was set as I left it in manual mode from previous shoot, once I had set it to macro mode then the lens was fine.
