Originally posted by FotoPete Hey Roy, you've done some tinkering before. What do you think about the tiny black screws that are on the flange piece that sticks out? (One is visible at 8 o'clock position on the second photo)
If you unscrew all those, the flange would just come out whole right? and you need not to whip out a dremel tool. Though I'm guessing the amount of open 'space' on the rear of the lens is gonna be bigger and you'll have to exercise caution to avoid dust getting in.
I modified my Serries 1 70-210 F3.5 by removing the tiny screws and dropping the flange out, I then modified the flange down to the size of a normal pentax one.
Lens looks for all the world like the series 1 70-210 F3.5 Version A that I own, except for the lack of the "macro" switch, that put you in close focusing mode.
What is the filter size, the version A lens is 67mm.
As for the price, I am shocked if it was $521. I bought my Series 1 new for $350 in 1981. I would expect a rebranded lens to be cheaper not more.
Also as you can see from my location, there is not a "rebranding" of the vivitar products for the canadian market. To me this seems to be a rebranding for a retail chain from a third party manufacturer. It would be curious to see the serial number as that might tell who made actually it,.
Optically I have been very pelased with my S1 lens, the only complaint is the weight of the front group, and the fact that the zoom length drifts if the lens is pointed down on a tripod. Lacking the tripod mount, I don;t use this often on a tripod also due to the weight, but it was a great walk around nature lens.
