Help - Canon Fisheye Filter size?

For reasons that I am sure many of you can guess, I would like to know the drop in gelatin filter size for the Canon 15mm FE.

Please provide the filter size in mm - so that we can ensure it(!) fits your lenses.

Thanks

Alex

Oh, and before you all say ask Canon, I already did:

Incident Number 1982238

Thank you for your recent enquiry regarding Canon EF 14mm f/2.8L USM and

EF 15mm f/2.8 Fisheye.

Regrettably, we do not have any information on the filter size for these

lenses.

<_<

Customer service, another reason to buy Nikon....

Dang it Jean you beat me to it!

Ho, ho, children.

The only reason I didn't have to ask Nikon is that I already have the lens. They may not have been any more helpful either!

unbelievable but typical! And praise Sigma too in this regard!

Alex, just checked my counter, sold out of 15mm & 14mm Canon for now, but just in case here is the dimension for a Tamron 14mm filter if ever asked.

25mm high to 27mm wide

Just checked into the box of brand new Nikon 10.5mm, there is a template included and double checked with Nikon Canada they had the info back to me within 5 minutes B).
