Hi all,
A pawn shop here is closing down and they're having a big sale to get rid of their stock. I went in today to see what they had left, and found something I'd never seen before.
A genuine Asahi Pentax 67mm polarizing filter specifically made for Pentax 6x7 lenses (it's bayonet mounting). There was no price on it so the guy offered it to me for NZ$50 - a bit higher than I'd have liked but he wouldn't budge so I bought it anyway. At today's exchange rate that's... about US$35. I have no idea what it's really worth, either new or secondhand. B&H have a number of the 6x7 filters listed but not this one (no, it's not the horrendously expensive drop-in polarizer for the big lenses).
It appears to be a circular polarizer as it doesn't affect the metered prism finder. The design is quite clever: the front does not rotate which is a very good feature if you have a lens hood attached.
It fits the 90mm f/2.8 and the 165mm f/2.8 nicely. I guess I now need the 82mm version to fit my other lenses, but considering how often I use the things I probably shouldn't have even bought this one.
Cheers,
- Dave
