Camera Lens ?

I picked up a Vivitar 85-205mm 1:2.8 lens number 22530272
today and i was wonering if they sell a adaptor to convert these old lens
for dslr cams?

I have a sony a100 and i would love to be able to use this lens with it. The zoom on it looks cool and the macro features on it are neat.

I just hope i can get a adaptor to fit it.

If not what camera would it work on?

Your lens is a manual focus lens. The Sony A100 is an autofocus camera. So, you won't get metering or autofocus.

If the Vivitar is a screw-mount, you might be in luck for a converter/adapter--there are M42 screw mount to Sony/Minolta AF adapters available, even on amazon.com

If the Vivitar lens is any other mount, then you are out of luck. If it is a Minolta MD mount lens, there are Minolta MD to Sony/Minolta AF adapters, but they are of poor quality--they have to add a glass element to get to infinity focus and this greatly degrades image quality. Any other mount--Pentax, Canon, Nikon, etc--and there's no adapter.

You might also want to see this page; this person apparently developed a work-around to allow old Minolta lenses to mount to Sony AF mounts:

Otherwise, to figure out what camera your lens would work on--first figure out the lens mount on the Vivitar and go from there.

You might find an adapter here...

... IF you first know exactly what camera the Vivitar was designed to mount to. All camera manufacturers use a proprietary lens mount so there is no compatibility. Nikon uses a Nikon mount, Canon uses a Canon mount, Sony uses the Minolta A-mount (which dates back to 1985).

So your first task is to find out exactly what camera the Vivitar was designed to fit. Then you may be able to find an adapter.

IMO you'd be better off selling the Vivitar lens and buying a Minolta Maxxum AF 70-210mm zoom. It will work perfectly with your A100.
