Is there a way to mount a Canon C-mount TV lens to a 7D EOS body?

<p>Anyone know how I could mount a Canon 50mm TV lens with C-mount to an EOS 7D? I am wondering if that lens would even work on the body? Thanks for any help/comments.</p>

<p>Even if you could mount it, it probably wouldn't cover the entire sensor. Video camera sensors are smaller than DSLRs.<br>

Is there a compelling reason you want to do this?<br /> <br /> <Chas></p>

<p>Duct tape?</p>

<p>No, it won't work. It wouldn't cover the sensor and it wouldn't focus past a few inches even if you duct taped it to the body and ignored the fact that it only illuminated a spot on the middle of the frame.</p>

<p>A) designed to cover a much smaller sensor than on your camera, so even if it were to mount and work you would only get a very very small image in the very centre of the frame.<br>

B) It's not a mechanical fit and as such will not mount without an adaptor, I would doubt that such an adaptor exists because<br>

C) The back focus is far shorter, meaning, even with a smaller mirror like on a 7d, the rear element will foul and possibly cause damage.<br>

The only percieved benefit of fitting a TV camera lens would be a powered zoom demand. But you have no power source.. as this comes from the TV camera body.<br>

So in effect you have a lower resolution manually operated lens with a greater zoom capacity but extreme crop.<br>

You will be worse off than if you just used the much higher resolution Canon EF or EF compatable lenses.<br>

I have been blown away by the video quality of the 7D, and will be using it along side my Digibetas (for sound) as it is that good. There is absolutly no benefit at all to putting a C mount lens on the 7D. A bigma, possibly, a 28-300 L, or 35-350L possibly, tv camera lens. NO!</p>

<p>Inverted for macro?</p>

<p>C-mount lenses covering the 1" format can be used with an adapter on micro Four Thirds cameras, although I'm not sure it would work with every lens.<br>

I have a 12mm F0.8, a 8-48mm F1.2 (both for 1/2") and a 25mm F0.95 (1"), it would be cool if some manufacturer would make a compact camera to make use of them, although I suspect their wider aperture brightness advantage is counteracted by small pixel pitch when using several megapixels on a small sensor.</p>

<p>There are several adapters on the market. I am currently waiting for one to arrive. What people are saying here is mostly correct. I'm interested in the adaptation for the extra low-light sensitivity, and macro, vignetting doesn't bother me for what can only be experimental shooting. Don't expect to shoot regular pics or video though. For that, you'll have to go to a micro 4/3's body and a c-mount adapter. Those look pretty awesome.<br>

I'll post results.</p>
