Prompted by a recent thread involving the Vivitar Series 1 35-85/2.8 lens and its modification for newer K-mount bodies, I'm providing some images involving this lens:
Here are two VS1 35-85/2.8's, the left one of which shows the extra baffle, while the right one has been modified: <http://www.cetussoft.com\pentax\v358528\1ofeach.jpg"> It is important, of course, to mask off completely the rest of the lens when the extra baffle is being removed: <http://www.cetussoft.com\pentax\v358528\lensmod.jpg"> It is also possible to remove the K-mount flange and then remove the extra baffle after masking off only the flange: <http://www.cetussoft.com\pentax\v358528\flangmod.jpg"> A description of the VS1 35-85/2.8 in a 1976 Vivitar Series 1 brochure: <http://www.cetussoft.com\pentax\v358528\brchdscr.jpg"> Specifications for and a photo of the VS1 35-85/2.8 in the same Vivitar Series 1 brochure:: <http://www.cetussoft.com\pentax\v358528\brchspcs.jpg"> An ad for the VS1 35-85/2.8 from 1975: <http://www.cetussoft.com\pentax\v358528\ad7510mp.jpg"> An ad for the VS1 35-85/2.8 from 1976: <http://www.cetussoft.com\pentax\v358528\ad7607po.jpg"> An ad for the VS1 35-85/2.8 from 1979: <http://www.cetussoft.com\pentax\v358528\ad7904mp.jpg"> Another ad for the VS1 35-85/2.8 from 1979: <http://www.cetussoft.com\pentax\v358528\ad7907mp.jpg"> Fred
