Focussing screen EC-S availability

Steve_B — Tue, 03 Feb 2026 14:38:27 GMT

Not sure if this is the right place to post this, but does anyone know anywhere who definitely will be able to supply the above focussing screen? It's used on the 1dx mkii and 1ds mkiii. I've browsed the usual suspects, ebay etc and just had a general look in 'shopping' on google but sadly drawn a blank. Canon obviously no longer supply them and I don't mind if it's used (not sure if I'd get a new in box one) as long as it is 100% mint condition.

Any help gratefully recieved.

I think that screen is over 10 years old. Although it may fit in a 1DX I doubt it was designed for it. You'll just have to keep searching. More of that kind of stuff is more available in Japan so you might want to try searching there.

The Dx mkii and Ds mkiii share the same focussing screens, I checked, 🙂 Have you any links to Japanese suppliers I might try please?

"The Dx mkii and Ds mkiii share the same focussing screens, .."

I realize that but that is a coincidence, not proof that it was designed for use in the 1DX series because it wasn't. Since my father has passed away I don't have any real good sources in Japan. You will have to do a search for them.

Maybe it was maintenance, because it's back up, but drew a blank looking for what I want. Oh well.

Do you mean Ds Mark II?

Dx MII and Dx MIII share the same screen but not EC-S.

No, as I said in the OP I have a 1Ds mkiii and a 1Dx mkii and the part number for the screen I want is the same. Ec-S.

You OP said “screen? It's used on the 1dx mkii and 1ds mkiii. I've”.

“… I think that screen is over 10 years old. Although it may fit in a 1DX I doubt it was designed for it.”

What JRH and myself are saying is although the screen may fit a 1DX or any newer 1 Series model, it was not designed for them and since it was designed for the much older 1Ds Mk III, it may be well out of production. Finding one may be a challenge.
