EF lens diameter of image field.

Dear friends,
 
I need to know exactly the size of the projection circle or diameter of image field, of my Canon lenses. I am not finding this information online or in my Canon documentation. Please, I ask you for this information.
 
Lens:
Canon EF 100mm f / 2.8L Macro IS USM Lens
Canon MP-E 65mm f / 2.8 1-5x Macro Photo Lens
Canon EF 40mm f / 2.8 STM Lens (with Macro function)
 
In the future I intend to acquire some excellent and new Canon Tilt & Shift (50mm, 90mm 135mm) with macro capability and I know that they have a huge projection circle or diameter of image field, that will freely cover the medium format sensor, but I also don’t know specifically its circle measurements projection. If you can provide this information as well, I am also very grateful.
 
Thank you very much for your precious help.
Good health for you.

Thanks. I am aware of all that. But thank you very much.

The Zeiss Classic/Milvus/Otus DIF (Diameter Image Field) is 43mm (all lenses but the Otus 28mm = 43,3mm ).
My sensor is 0,8mm bigger than 43mm. An hair but, there is a tiny difference.
Where is Canon lenses DIF?

It is not specified, at least not that I have seen. It might be buried in a white paper on a specific lens. That is the nice thing about designing to your own mount.

Maybe .-)

I have never seen it specified. Possibly because Canon, unlike Zeiss, is manufacturing their lens for a specific camera system and therefore no one needs to know that property of the lens.

Possibly true.

Hello, Cunha,

According to EOS Magazine, the image circle of an EF lens is 43.2mm and EF-S is 27.3mm. This article is about tilt/shift lenses, which have a much larger image circle.

I hope this helps.

The TS-E 50mm f/2.8L Macro, TS-E 90mm f/2.8L Macro and TS-E 135mm f/4L Macro all have an image circle of 67.2mm.

Yes I know .-) Amazing lenses. Thanks.

If their image circle is 43.2 it’s good enough to cover most pixels in a MF sensor (I.e. 44mm * 33mm)

I saw from some adaptor manufacturer that this circle is not constant across all lens. I think this number is probably the best possible scenario. It reported telephoto lens works better than wide angle, but I would think it should be the other way around.
