Pentax 6x7 filters

[chicodovale]

I bought recently a Pentax 6x7 with two lens (Takumar 1:2.4/105mm and

1:3.5/55mm). I would like to buy some circular polarize filters for

those lens but I don?t know exactly the filter size. I guess that

for 55mm lens the filter diameter is 100mm, but for the other one I

don't know anything. Does anybody can help me on that?

Here is a link to a Pentax 67 lens specification page:

Francisco,

 

Is this for the old 67? You know you can get away with a linear polarizer for that camera. I'm not familiar with the 67 II so I can't advise you if you can get away with a linear polarizer. The difference in price between linear and circular polarizer is pretty significant. Regardess 100mm filters are pretty rare, you'll be better off getting a 105mm and a step down stepping ring. The other filter size is, I'm pretty sure, 67mm.

The 55mm does have a 100mm filter thread, and the 105mm has a 67mm thread.

Thanks everybody for helping me. The table has everything about Pentax 6x7 lens (http://web.mit.edu/dennis/www/pentax67/lens-info.html). Very good suggestion. My problem now is to find this type of filters and in good prices.
