Are Canon lenses compatible with other EF mount cameras?

[jimbe0]

I'm looking to buy my first pro camera but don't have the budget for a new lens. I have an amazing EF mount lens for my eos rebel t2i. I'm thinking of getting a black magic pocket but since the lens has a digitally controlled aperture I'm worried that if I use it on a different brand I won't be able to adjust the exposure without changing ISO or shutter speed.

Does anyone know if a canon ef lens would work on other cameras?

They claim compatibility with EF lenses and have an active lens mount to control lenses.

All EF Mount lenses use an electronic aperture control. Never a mechanical aperture control. In fact the EF Mount is 100% electronic. There is no mechanical interface that includes autofocus. If the camera has an EF Mount the lens will work. I am NOT sure about EF-S lenses. On the Black Magic Cinema cameras. I think that there Full Frame not APS-C. Thus making EF-S lenses incompatible.

It would be best to consult the blackmagicdesign spec sheets and forums for specific questions.

Having said that, what specific lens do you have? If it's EF, it would work.  If it's EF-S, it may work.  The blackmagicdesign gear that has an EF mount are both using a Super 35 sensor which is very close (but not exactly the same) as APS-C like your T2i uses.  So it's possible that an EF-S lens could lead to strong vignetting in the corners.

Super 35 would be around 26.2 mm by 13.8 mm.   Whereas APS-C would be around 25.1 mm by 16.7 mm.  So while an EF-S lens could cover the height of a Super 35, it's a tad shy of covering the full width.

Any Canon EF lens will work on any Canon camera with an EF mount.

Your T2i has an EF-S mount so you can use EF-S lenses as well.

I'm wondering if this is SPAM.  A different profile posted word-for-word the same question two days ago.

Its SPAM.  Waddizzle and I discussed it briefly the other day. (he noticed it)
