Are there any tips or anything I should know before trying to fix a Vivitar 75-205mm zoom lens?
This lens is the autofocus one that had the AF mechanism built into itself and was made to fit manual focus slr cameras. Rememmber those?
It doesn't autofocus. Checked all the usual stuff like battery contacts and new batteries but nothing. |

Oh, yes. Those were called S.C.A.F. for Self Contained Auto Focus or something like that. A regular zoom lens but with an autofocus mechanism built into a "hump" on the side of the lens.
I recall the advertisement for them. They were intended for people who wanted to try AF but only had a non-AF camera. Vivitar made two of these if I recall correctly. A 28-70mm and the 75-205mm.
Believe it or not I have a "generic" version of the lens made by Starblitz and it works but the cheap plastic gears "slip" so it doesn't do anything. Truly, I don't see how this Starblitz could have worked even when it was new the mechanism is so crappy. |

75-200 actually. I have both of them, they are both good lenses. As far as the AF systems go, they worked well for a respectable amount of time, but I don't think they do any more. I do have some disassembly notes on both of them, which I'm happy to share, but I don't think I can claim to have actually fixed either one. But I'm not an electronics type person. |
