Canon LTM Canon 40mm Slimline Filters- What is Available?

[Nokton48]

Hi All,

I just receieved today (from Pacific Rim Camera) an original Canon 40mm Slimline Filter, designated "G1". It's a useful for B&W yellowish-green color. I have found these Slimlines to work best (esp at f22!) with my new 35mm f2, which is currently at Essex Repair, for a CLA and fix of looseness and wobble. Also sent my new 85mm f1.5, it has a sticky helical.

Anyway, what other filters in 40mm Canon Slimline are (were) available? In addition to the "G1", I also have the "UV/Sky" 40mm Canon Slimline presently.

Thanks! -Dan

I'd expect Y1, Y2, RO (orange), GO (yellow-green), R1 (red) for B&W filters.

For color, filters for conversions between 3200K or 3400K and daylight (5000K), both ways. (Pretty much obsolete.)

HI Dan,

As you mentioned it was a flat style G1, then it is from the era between 1955 & 1956. The other 40mm filters issued with the G1 were the 01, R1, Y1, Y2, Y3 and a UV, which could only be purchased in a separate clear plastic container. All the rest could be purchased separately or in a coded colour filter stack. These filters will be marked as mentioned. They do not appear on the open market very often so you may have to be content with a step-up ring. Peter

Thank you Peter & John!

i use the 40->43 adapter and have no problems
also have no problems using the walz 40mm filters, non slim.

Amazingly, I was getting really awful vignetting at f22 with the 35mm f2, using 43mm filter/stepdown ring/43mm vented hood.

Best combination I've found is the 40mm Slimline, and the Canon Hood for the 35mm f2.8, No vignetting at f22 🙂

Got -alot- of stuff from Heavystar to re-sell. Eric, I will try the Walz filters, they do look slimline to me

They did blue ones as well.

Waltz provided similar filters* and a matching vented hood in a kit. 'Shows up occasionally on the auction site. HeavyStar adapters are an option.

*as already mentioned.

HI, GordonB pics are the earlier drop-in filters from 1950-52 and require a hood or adapter rings so they can be used. The coloured stack for the flat filters is the same as shown but the screw-in flat filters coloured stack is not as tall as the drop-in stack. I have developed a chart which makes it easier to identify all Canon RF filters and when they were issued right down to the case/box they were sold in. Still contemplating whether to include a fold-out page in my next book on Accessories or do a disc or both? Peter

Can't seem to see the pictures. Folks from Asia have to pay US$9 to access.

Cheers,

oh thats just stupid.

these are both skylight. im thinking of popping the bad glass out of the canon and putting in a red.
ok they wil work now

Thanks Erik,

I think the filters with threads only on one side don't have retaining rings. As such, we may not be able to pop out the glass and swap them. Perhaps someone has tried and can give comments.

Cheers,

so i finally looked at a roll i took before the shutter crapped.
this is the only frame on the roll that had vigeneting.

It's more of an issue at f22 and f16 with the 35mmf2. I'm not 100% sure, but I doubt you'll see it much at F2. I guess Canon offered the slimline 40mm filters for a reason :bang: I have found that the Heavystar 43mm with 40mm adapter dosen't work at all; You get a full circular vignette/image-cutoff well into the image area on both sides at F22.

i guess by f8 everything seems in focus so i never needed to stop down any more.
