Classic Vivitar Series 1 70-210mm f3.5 Macro Zoom lens with Vivitar Multi Coating. Fast max aperture of f3.5 at all focal lengths . Caps supplied . In full working order . The reason this lens is only £20 inc post in the UK is that there are some small fungus patches inside ( see the last two pictures ) , so not full elements covered in fungus and haze , just some small fungus patches , if you know how to get into the lenses and clean the elements , in my opinion this should clean up .... no chalky haze or separation ... the glass is bright apart from these random patches . Uses 67mm filters . A fat chunky lens packed with glass . Serial number 22921277 . This lens has the Canon FD manual focus mount and will not mount onto any camera with the word EOS in the title but it is adaptable to some of the Digital platforms via FD adapters that are available on ebay. Free UK P&P.
