Vivitar 24mm

Up for sale 24mm 1:2.8 MC with A lock button. Good condition. £35 plus p&p open to offers

Could you be a bit more specific. Vivitar made a lot of them.
Is it in M42 mount or K-mount. Perhaps post a picture?

Thanks in advance,
Martin.

Yes it is a PK mount. I have some pictures somewhere, I'll try and sort some out later
