Its an EF mount, so you will at least be able to attach it to the body.

You mean “Old Ben”? Ben Kenobi?

Just thought of something, how do folks get remote zoom functions on any of these EF mount lenses?

When I’m shooting sports, I can’t have my hand on the lens in order to zoom in or out. $40k for a Canon Cinema lens is out of the question.

Canon’s 10-22 EPS zoom translates to 15mm – 33mm on the Cinema Camera… a very nice, affordable lens. Should do the trick, especially since you’ll be shooting through the sweet spot in the center.

[Shane Betts]

A 10-22 would deliver the equivalent of 20-44 on this 2x crop sensor. Still not all that bad. And, yes, as you point out, you’re in the sweet spot – one of the major advantages of the smaller sensor.

Are you sure, or do I have the math wrong?

It’s my understanding that EF lenses will deliver the image of 2.4 times their full-frame rating, and EF-S lenses will deliver 1.5 times theirs. No?

[Shane Betts]

No:-( Focal length is what it is. A 50mm is a 50mm is a 50mm – except on some happy snappy cameras where they place an asterix next to the focal length and in small print somewhere mention they’re talking “35mm comparative” or some such marketing speak.

So, presuming your point of reference is a 36x24mm frame (full frame 35mm stills), Dx or super 35 (motion picture 16:9 default) is 1.6:1 and this camera is around 2:1.

[Mike Squires] “We’re looking at upgrading our ENG SD cameras (and field camera), and this is what we primarily shoot:

2-man @ desk in front of green screen for sports show
Some local commercial productions
College football (shot from the media booth)

Would this camera with this lens work:

We currently use JVC ENG cameras with Fuji glass (18x), which seems to work just fine for all of our shooting.”

There are many things to like about the new BmCC — I just pre-ordered one. The BmCC might be great for 2 of the uses you mention (greenscreen & commercials), but I don’t think shooting sports/action will be a good use for it.

As its name implies, the Blackmagic Cinema Camera is primarily intended for cinema-style shooting, not sports or for following fast-moving action.

Lenses designed for sports/action videography typically have servo motors for zoom and other features such as constant aperture and especially parfocal focussing. Lenses designed for DSLRs typically don’t have all 3 of these features. Although some DSLR lenses have constant aperture and parfocal focussing, it’s the lack of smooth motorized zooming that makes them generally unsuitable for sports/action.

A (funky) workaround might be rigging a manual follow-focus unit to the zoom ring (not the focus ring) of a constant aperture, parfocal DSLR lens, but the result won’t be as smooth or controllable as using a good servo-zoom lens.

Further, the BmCC’s maximum frame rate is 30p. For some sports/action shooting 60p can be a valuable feature, but it’s not a feature offered by the BmCC.

Cheers.

Peter, thanks for your response.

Yes, we have found a work-around like you said for the lack of servo zoom:

And since our current cameras are SD only (480i), shooting in 30p would give us the same results as I currently get. After a couple of years of practice shooting football with our cameras, I’ve learned not to pan too fast, and try to anticipate how the play is unfolding.

I guess I should have also noted that we don’t air these games live or stream them, I edit the footage for highlights for the coach’s show that we produce.

I’d be interested in finding a lens that does have the other two features you noted. The only other feature that would be great is auto-iris, but I can manually control that if need be.

Thanks again for your comments, and any other insight would be appreciated.

In tech sense there is nothing special to it. One can really make that one at home
if you do not need all the additional stuff to gears and buttons.

Under 100 i bet

Seems nice option for remotely adjusting lens as an idea still.
