UV Filter for Canon FD / FDn 85-300/4.5 Zoom Lens

[roundballmflenses]

Looking into Canon 85-300/4.5 lenses, am hoping to get some information about it's filter design.

I was looking at a FDn version and instead of having a screw-in filter in the front, it had a screw in retainer ring, which then held a filter in place that had no threads of it's own, just a metal band around the circumference of the glass.

I have a BL / SSC version coming and it seems to have the same design...in the event I need/want to add a UV filter, trying to finalize information I'll need to try and find one. So far my searches have turned up some limited pieces of information, which don't then seem to find any or point to any source when I Google search this ID info:

Series IX 82.6mm Filter (3 & 1/4")

I have seen occasional references to Series 9.....and Roman numeral IX is 9.
Could be that what's being referred to as a Series 9 is the correct filter, just not sure and kind of expensive to order on the assumption that's the case, so I thought I'd toss the question out to the MFLenses braintrust.

If anyone knows / can validate the specific ID info for such a UV type filter for the Canon FD/FDn 85-400/4.5...and/or know where I can find such specific information...I'd appreciate the help...thanks.

I have the same lens, boxed, won't be home until tomorrow evening, pretty sure I have all the paperwork that goes with it but don't hold me to that. I will check when I get home, there may be a technical sheet if we're lucky. I can say it's a fantastic lens, don't think you will be disappointed.

The earlier SSC version with the breechlock has a filter holder for Series 9 filters. The nFD version had an adapter supplied with the lens for 82mm filters.

Series filters have no thread, and are held on by a retaining ring, just as in your case.
You should be able to find Series IX/9 accessories on eBay, like a hood, but they arent all that common.
Best thing to find IMHO is an adapter ring to some common metric size like 82 or 86mm.
Again, these aren't common, but I have run across them in the past.

Hi again, just checked mine, luckily I have the adapter and filter fitted, have a booklet with info in but it sheds no new light on the matter. The retaining ring is a bit like a blank step down ring and just unscrews, bit of a bigger with the built in hood, and then the filter just pops out, mine is a skylight, I have noticed a tiny machined hole in the hood and I can only assume that as the retainer has a knurled edge it may be an access point should it be a bit stiff.Hope this helps, worst darn system I have ever seen, but shouldn't detract from a damn fine lens, I will shortly be adding an adapter to the retainer, however this will render the hood obsolete, so will have to find another hood, the things we do for our passion never surprises me, good luck finding the retainer and filter.

The hole in the hood is usually meant to provide access to a polarizer when the hood is extended.
Seen that on other lenses.

Being a series 9 filter which is enclosed by a retainer there is no possibility of using a circular polariser with a thumb lever, any polariser would have to be linear.

Thanks for checking that paperwork;

Have been checking EBay;

Thanks for the links about filter sources;

Actually there were circular polarizers for Series filter mounts, for these you do not use the retaining ring.
I have an old Series VII Kodak polarizer like this, lovely chrome brass, complete with a knob. Sadly it has separation.
