canon 70-200mm ultrasonic zoom lens fit on a canon

Javv10 — Mon, 23 Oct 2017 17:08:20 GMT

a canon 70-200mm ultrasonic zoom lens does not lock on my camera. It's a canon EOS rebel T2i. It was a gift and I need to know what should I do.

It should work perfectly with your camera. Did you try matching the lens red button with the camera red button (instead of white)?

Is it an EF or EF-S lens? An FD or EF-M won't fit.

I don't think they make a 70-200mm EF-M.

...and I don't think they made an 70-200mil ultrasonic either.

I was just being complete, he might be listing FF equivalents for all we know.

Take a picture of it, or two, so that the gurus can see it.

Well, I just looked. Mine says "USM". I believe that stands for "UltraSonic Motor".

Maybe just the lens cap says ultrasonic. I have like 4 lenses with 77mm lens caps and one of my caps says Ultrasonic, but it floats around among the different lenses. If I sold a lens there'd be a 1 in 4 random chance that cap would go with it.

Come on, Scott; I was born in the morning, but it wasn't this morning. (Actually, it was 80 years ago last Friday.) It says USM on the lens.

" An FD or EF-M won't fit."

"Well, I just looked. Mine says "USM"."

The reply was in responce to your reply. Not that they never made an Ultrasonic 70-200mm lens. Yours is not an FD or EF-M is it?

Geez, it's a rough crowd aroud here!

It's say USM

USM

"It's a canon EOS rebel T2i."

Well in spite of this nomenclature misunderstanding, USM or whatever, any "EF" lens will fit your camera. That is all the letters you need to know. Before the others jump in again, I am not aware of any ef-S 70-200mil zoom.

But an EF should fit just fine.

To help clarify the type of lens, it should be written on the end of the lens circling the glass. It should read along the lines of "CANON EF 70-200 MM 4.0 STM / USM / etc."

The lens MUST read "EF" or "EF-S" in order to fit. An AF or EF-M will not fit.

If you don't have any problem with any other lenses fitting, you might want to check the end of the 70-200 lens for damage or debris.
