Hi All,
Just a quick question for the folks using Pentax K versions of the first group of Vivitar Series 1 lenses (my experience with these lenses has been limited, until now, to the M42 versions).
Can I pretty much count on the fact that I would have to grind away the extra flange in order to use any of these lenses on my K20D? I'm not at all nervous about the actual grinding procedure, but I have some concerns about being able to mask off the area securely enough to prevent stray metal filings from getting inside the lens. (I've seen this discussion, but any additional suggestions would be most welcome.)
Thanks!

I can't say for sure about your Viv, but I've been lucky with a couple of other makes with a large shield, in that the shield was on a plastic moulding easily removed from the lens before cutting. _________________ Dave - Moderator

Hi Jon,
I don't have an S1 Viv, only a Viv 75-205 3.8, which i needed to shave to fit on my K10D. I used a micro-fiber cloth to protect the rear element of the lens and the mount, and some adhesive tape, to get a setup almost as the one showed in the other thread.
What is important, IMHO, is to use a big cloth, refolded more than once on itself and a lot of adesive tape (i have used the yellow one, the kind of tape used to protect a the painting of car when you fix a little scratch - don't know how it is called in english), to prevent metal filings inside the lens.
Hope this helps.
Best wishes for your S1.

That flange is usually on a removable plate and only held in place by three or four small screws. Not hard to remove at all. Good luck with it. _________________ Big Dawg |

So, this means that i could have removed the plate with the flange to use the lens with my K10D, instead of shaving it ? Is the flange used only to protect the inner lever ?
