Canon CINE SERVO 17-120 T2.95

Does this cover a full frame sensor like their other cine glass?

Most cine glass does not cover Full Frame sensors if referring to photography format.

Some do, many do not. This lens is like the many. It will not cover FF formats like the 5DmIII. It will cover S35mm cameras and maybe some sensors a little larger.

All other Canon Cine glass does not all cover full frame either. Just some of them.

Interesting. I was under the assumption all Canon made cine lenses covered full frame so they could be used with the 5D cameras if desired. Which I thought was kind of unique. Good to know they all don't.
 
Only the Canon Cine primes cover full frame. The Canon Compact Cine zooms (15.5-47 & 30-105) cover Full Aperture 35, which is large enough to cover a RED at 5K or an Alexa Open Gate 4:3. The Canon Studio Cine zooms (14.5-60 & 30-300) cover Super-35. This new lens will cover the same as the Compact zooms.
 
Just wondering out loud, how much better is this lens supposed to be than a 24-105 for example? I realise there is a way lower production rate with the cine-zooms but more than 30x the price is a lot to grasp!
 
Well, that is why I am asking. I have never used a cine lens. :) Is this something everybody can spot right away watching the comparison footage?

It's a parfocal lens designed to be used with cine focusing systems, which makes it much easier for hands-on or remote focus pullers to keep a sharp image at all times.

Comparing a 24-105L to this Cine lens is like comparing a Sigma SLR prime to a Cooke S4.

Actually the resolving power of some of the new Sigma lenses would probably be at least as good as their S4 equivalents.
However, that is not of course why people buy cinema lenses.
 
Thanks. I can see the need as SLR lenses are a mess outside of electronic focus still work. I would hope the cine lens blows away the SLR lens optically.
 
I have the CN E primes except for 35 and I have the 30-105. I bought it partially to give me a compatible 35 to the primes. It is constant aperture t2.8, par focal. It covers super 35 and it covers the 1.3 crop on the my 1Dc, but not full frame. It is a gorgeous lens.

I hemmed and hawed about getting the 15.5- 47 or the 30-105, because I thought the 15.5 would make a better run and gun lens. But in testing 15.5 looks "video" and the 30-105 looks "cine" because of the background bokeh. It is quite apparent when cross shooting with same size image area.

I don't know how I feel about this lens, well I do know, I want it. If it had been available two months ago would I have bought the 30-105? probably not, but I love it and am happy to have it. If I had bought the 15.5-47 I would be pissed. I almost bought both, to have the range, but in cross shooting they just didn't match, I suspect the 17-120 will.

My long term goal is to get one more 4k body to go along with my c500 and 1Dc. I am waiting to see if there is a MKII coming along to the c500 or if Dragon ever becomes available. If I do get another c500 type body, I will probably get this lens. It would make an incredible cross shooting kit with the two zooms.

For my style of shooting the 14.5-60 and 30-300 are out of the question to own. But they are magnificent.

I am looking forward to the new Zacuto zoom control to test on the 30-105.

These lenses are huge investments, but incredibly useful and satisfying to own.
 
The specs say it is constant aperture T2.9 from 17-91mm ramping down to T3.9 between 91 and 120. You get the extra stop over most of the range.

Yep, and I'll take the 1 stop loss for that bit of range beyond 91mm any day of the week. Wider, longer, & cheaper than the Cabrio - plus interchangeable mount to boot! This is going to be a very popular lens.

Why? Set it to T4 for constant aperture.

I don't think that's a slam-dunk choice, Mitch. Might as well just call the lens a T4 then.

Doc type shooting is one thing, you are constantly tweaking aperture for a given setup. No big deal. Even with this scenario however, if you are doing something as basic and typical as a headshot interview, you may be looking to throw the background out as much as possible, so you'll want to work under a 4. But then what happens if you need to snap in to a tight shot of hands etc. Sure, you could theoretically light to a 4 and then add an N3, or dial down the ISO etc. But then it's extra things to remember and plenty of opportunity to screw it up.

I had the same issue with the 30-300 when it came out. I could easily see it being used on a series or something where the director is calling mid-scene "punch in! punch in!" and the operator has to crane his head around to make sure he isn't pushing past the point where the lens will start to clamp down. You know that people are forgetting about that and footage is coming in underexposed by up to a stop for certain shots.

What I wish Canon had done is to add a mechanical plunger to the lens barrel, something along the lines of the macro button on ENG lenses. Stops the zoom at the limit of the minimum aperture, or you release the stopper to allow full range. Just helps to act as a reminder if nothing else.

It has the electronic interface menu system in the servo handgrip like other modern Canon zooms. There's a bunch of things that can be controlled there but most people never look at it and have no clue. One function is an electronic range limit to stop the zoom range wherever you want it. Good for designing a shot and good for protecting you from zooming into the aperture ramp.
