  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Checking out this lens and looking for reviews.

I came across a review but it doesnt show any footage just a few stills compared with a regular EF 24mm.

The stills seem a little odd. The focus looks different as well (his hands holding up the card).

Why the heavy vignette on the Cine prime comparison?

Here is the video:

and the stills:

anybody else have any R3Ds or stills from this lens?
 
I like the result of the improved lens coatings - the color and contrast are noticeably better than the L-series, and flare seems better suppressed (more detail is coming through in the highlights on the lamp). The vignette is a bit disconcerting, though. I hope that goes away when you stop down.
 
It's not making sense to me either - the L-series covers full frame with no major issues, so I can't imagine why the cine version would vignette on an S35 chip. I guess we'll just have to wait for more comprehensive tests to come out.
 
These examples were most likely shot on a Canon camera with "peripheral illumination correction" turned on. The Cinema lenses aren't recognized in that database and therefore the camera doesn't automatically correct the vignetting.
 
So was this shot on a Canon camera or Red.

Whichever Id not want the lens to Vignet. One of many reasons we are trying to buy FF 35mm glass at the moment including Leica R and Canon K35's. It would be very good if these new Cinema lenses worked well.

I use old manual lenses so I never run into this kind of BS, do Canon DSLRs apply this even to raw files or was this guy dumb enough to shoot lens comparisons in JPEG?
 
The video makes it look like the tests were shot on a C300, so raw isn't an option there. I don't think we'll have to wait too long before someone puts these on a 5D and does some proper raw tests, though.
 
Guys, the photos have been shot on the Canon 5D II, just like Peter said in the video. I know Peter, will contact him tomorrow to get more info on this strange vignetting. I like the nicer colours out of the cine version but would really burn to know how and if resolution and breathing have improved at all.
 
Yep, be good to know. The character of the lens is nice but need to know if it covers FF. Also any one know about the PL version ?
 
Peter thinks it may be because the lens probably doesn't cover FF, but he couldn't say for sure.

Just a wild guess... Canon just may have changed the lens design to cover S35 to keep lens size and weight down. If you go to the official website it doesn't say anywhere that the cine primes cover FF, however for some reason I think I read that somewhere months ago... (yes I did read it in the press release, update below).

http://cinemaeos.usa.canon.com/products.php?type=Lenses-EOS

from the official Canon press release:
"All seven new lenses are capable of delivering exceptional 4K optical performance and offer compatibility with the Super 35 mm-equivalent image format. The three single-focal-length EF lenses can be used with cameras equipped with 35 mm full-frame sensors."

link here:

So basically they cover S35 and "can be used" on FF. A very flexible term, I can use ANY lens on FF as long as I can adapt the mount but that doesn't mean it will be covered without vignetting. One more indicator they might have changed the lens design.

The only other thing I can think of is like someone else mentioned here before, the Canon 5D can not recognize the cine lens (yet) and not compensate and auto correct vignetting in camera. A firmware update for the Canon cameras could easily fix that but that's for photography use, I'm not aware of a electronic in camera vignetting correction for video or is there???

According to Canon the prime cine lenses are EF mount only, also a bit strange, all the people who bought a C300 PL or plans to buy the upcoming C500 PL won't be able to use the cine primes if they stay EF mount only.

Excerpt from the Canon website, link in post above: "...results from the 11-blade aperture diaphragms, fast t-stops and proven Canon lens elements. EF-mount only."

EF mount only!
 
They announced PL mount versions as well, but apparently those are on a different release schedule from the EF lenses.

I m sure I read that they were supposed to have FF coverage. May be wrong. I don't see the point of EF if they won't cover a 5D3 or similar cameras so I guess that are targeted at a C300/500 which being EF prevents them being used on most other cameras using PL. If they do over FF and are PL then Id be very interested.
 
That's what everyone thought but in my opinion FF cameras are not the main target camera for the new cine primes.
Main target cameras would be the C cinema cameras with S35 sensors and there are still a bunch of Canon DSLRs with APS-C sensors.
 
Downloaded the manual for these lenses. It says they do indeed cover full frame.
 
I just played with this lens and compared it to equivalent Zeiss Cp.2's.
It is sharper wide open than the CP.2's and most certainly the super speeds versions at T1.5.
The camera (5D MarkIII) absolutely recognizes the lens, you can see what aperture you are on on the liquid chrystal display and metadata is kept with the file.
The lens is sharper, but the coatings are less contrasty than the Zeiss, Zeiss is in fact sweetening the image with more contrast through their coating tech in order to give the appearance of greater sharpness.
Only the Macro 50/2.1 compares in terms of sharpness.
There were two problems I saw with the Canon lens. Occasionally it didn't make proper electronic contact and the image displayed flickered between fully closed and open. I do not know if the problem was the blades or merely the electronic transmission of the image.
The other problem is that there is very little space between the apertures on the ring. Thus an extremely short aperture "throw". If you accidentally touch it, you might just find yourself 2 or 3 stops darker.
Overall, the Canon is gonna win some hearts pretty quickly.

It does cover full frame and it does not vignette as far as I could tell.
