Are there any lenses that will not record video on the canon 7d?

[chaconkevin]

i am looking on buying some lenses and im using the 7d for video overall.

i was wondering if there were any lenses that will not allow the camera to record video?

also what lenses crop the image?

Not sure what you're asking about; the lens doesn't know whether you're recording video or stills, so ? I mean, the 7D doesn't allow autofocusing during video, so that's not really an issue, so -- what else are you asking here?

As for cropping, you'd only get cropping on the image if you were using something like 16mm cinema lenses or something like that.
