Old Hoya Filters

Currently playing around with my trusty old P30, which was my 18th birthday present 40 years ago.

Thoughts have turned to filters. I was just wondering if anyone knows if the old Hoya catalogues (circa 1985 ish) are available online anywhere, only my google-fu is letting me down on this one.

(I'm also trying to work out what filters might be available for my, new to me, Q10)

Thanks in advance

Good question. I am not sure they have changed that much. This may be of use:

I think all my filters are from the early 80s

Thank you SMC, I've already got the current download (via the Hoya app). I'm specifically looking for mid-80s Hoya catalogues

Any 40.5mm diameter filter will fit the Pentax Q lenses. Polarisers and UV filters are out there. Other types might also be around but they're not as useful for digital as they were for film. And, of course, the 01, 02 and 06 lenses have a neutral density filter built into the lens which can be activated from the camera as and when needed.

Nice to hear that someone else has a P30 from the days when it was common for it to be someone's first SLR. Still got mine. Haven't used it for ages, though. Perhaps I should...

Take a look at SRS Microsystems website in their used Pentax section!

Thank you LennyBloke and Lubbyman for your comments.

I know that I can use any 40.5mm filter, I just have an irrational loyalty to Hoya filters. I know that there are interesting, and dare I say it, better, filters out there - but it is Hoya all the way in this household.

As for sourcing, I have discovered that Amazon Japan's marketplace has more wallet friendly pricing for obscure 'retro' camera stuff than fleabay or any commercial outlets for used kit. Just need to be wary of shipping costs.

I fear my Q aside, has distracted from my actual question - are any old Hoya catalogues available online?
