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?
Answer
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.

DSLR camera lens question?
BabyMama
Im just curious what the 15mm-55mm what that means when looking at lenses? Other numbers too but still.
Also im interested in a cam but it is only a 3x zoom but if you buy the lenses does that add zoom????
Thanks, im new to the SLR cameras.
It was a sony dslr.... with a 15mm 55mm lense.
Answer
its the focal lenght of the lens.
15mm is the distance between the
the image sensor, or film, and the
lens glass. the lower the number,
the wider the lens and the higher
the number, longer the focal lenght
thus the more zoom. if you divide
the 2 numbers you get the zoom
number. 55÷15=3.6 meaning 3x zoom
power. a 18mm-200mm lens has a zoom
power of 11x
its the focal lenght of the lens.
