Any ideas where I can locate 40mm filter for Canon lens ?
I have checked the obvious places but "the cupboard is bare".

Any advice welcome.

It is normally a case of waiting and hope you get in first before they get snapped up. Which flavours are you looking for?

The original "flattie" 40mm Canon filters are as rare as hens teeth......

best bet to protect them is buy the stepup ring and modern filters, while hoping for the original ones are next to impossible

PS: I found that the original ones are prone to flaring without the hood anyway, so newer filters are quite better, I don`t use any on my lenses when I`m shooting now, just for storage with a cap

When I bought my Canon 7, I went on e-bay and started searching for 40mm filters and adapters. I quickly snapped up two BIN's for 40mm-Series VII adapters. What I found out a week later when they were delivered was that one Series VII was a Canon thread and the other was not. Apparently Canon used a different thread pitch and a finer thread thickness from the other 40mm diameter thread.

Be careful what you buy. Unless it is verifiably a Canon 40mm, it may not go on the lens at all.

Also, a Series adapter will let you use easy to obtain Series filters. You only have to find one accessory to fit the Canon. My Series VII filters are used on both my Canon 7 and Leica M2. Lens shaed are also obtainable with Series threads.

I can't find the specs on the B+W 40mm filters to find out their thread pitch but here is a link to their current line-up.

Note - I couldn't find a reference to the B+W filter sniki linked to on the B&H site on B+W's site.

Excellent reference on the hoary.org site too
 
After purchasing a Canon 50/1.8 lens over a year ago, I managed to find an original Canon 40 mm filter (skylight), and an original hood plus adaptor ring for that lens from www.kevincameras.com. I also just purchased a 40-43mm step-up ring plus a generic hood from Heavystar on the 'bay, which should arrive soon. I'm planning/hoping to use that on the Canon 50/1.5 lens I recently bought. I'll let you know whether the ring fits once I receive it.

To follow up on an earlier post in this thread, I purchased a 40-43mm step-up ring and a generic 43mm hood for my Canon 50/1.5, and tried it out last Saturday. It worked perfectly. I bought the step-up ring and hood from Heavystar on the 'bay. They were v. inexpensive, and he shipped promptly. I also purchased a couple of 43mm filters from B&H to go w/ this set-up. While it would be nice to find an original hood and filters for this lens, they can be quite $$$ as well as hard to find. This alternative approach works just fine.
 
Hmmm. I have a Canon 50/1.8 Serial #219258 with a Kenko Y2 yellow filter. So far, so good, but right after "Y2" is inscribed "#42." Then in smaller letters "5c" and after that "K 1/22.

All I can deduce from the inscriptions is that I have a 42mm filter. Why does everyone else have a 40mm filter for what is apparently the same lens?

Also, does anyone have a lens hood for this camera? If not, does anyone have an idea where I can obtain one?

Ted --

I am not familiar w/ the particular filter you describe, but I would be very surprised if the filter ring on your lens is not 40mm, rather than 42mm. I managed to find a Canon skylight filter to fit my Canon 50/1.8 lens (a later serial no. than yours, but that should make no difference). It is a 40mm filter. I can also use this filter on my Canon 50/1.5, which also has a 40mm filter thread. I also tracked down an original hood and clamp-on adapter ring for the 50/1.8 lens. The adapter ring is 42mm, so it fits over the outside of the lens. The hood screws into the clamp-on ring. This hood, BTW, was also intended to work w/ the Canon 35/2.8 lens.

IIRC, I purchased the filter, hood and adapter ring from Kevincameras. I've forgotten whether this was an ebay sale or whether I purchased it directly from www.kevincameras.com. The Canon hoods, adapter ring, and 40mm filters are hard to find, which is why I went the generic route (described in my post above) for the 50/1.5 lens.
 
Is the Kenko a push-on filter? If so 42mm is the right size. To be strictly correct, the screw in filter size for the Canon is 40E. ;)

Hi, Kim:

Actually, it's a screw on filter.

Thanks, Steve, I'll check out their site.

I think the currently-available 40mm filters are a great way to go if they fit your budget, especially if you have an original Canon clamp-on hood, which won't fit over a step-up ring.

The step-up ring solution works great if you already have a bunch of 40.5mm or 43mm filters on hand, and it can help cut the number of different filter sizes needed for various lenses. Step-up rings can also minimize/eliminate vignetting problems which can occur using standard filters on Canon wideangle lenses. Hood choice/use may be a bit trickier, and you might get a bit more finder cut-off with a stepped-up filter and larger hood.

FWIW, new 34mm filters for the earlier Canon/Serenar all-chrome wide lenses are easy to find these days since it's a commonly-used video camera filter size.
