C200: Lenses for C200

The Sigma 18-35 has some noticeable vignetting when close to wide open, but that is just a characteristic of the lens. You don't reach the edge of the image circle for the glass like you do with some of Canon's ef-s lenses. Canon has vignetting corrections in camera for its own lenses which Sigma can't supply.

Interesting. I've never heard of this, how would you do it without messing anything up with the lens?

@ Chris F: Sorry I was traveling and didn't see your question. You don't exactly mess anything up--it doesn't remove the contacts or change back-focus. But by removing the rear plastic , you leave it much more vulnerable to dirt and dust. So attempt this at your own risk, but it is very easy & straightforward.

My camera and lenses are at the office so I can't show you directly, but here's a vimeo link to someone doing the procedure:

The new Sigma firmware for their lenses that's coming up sounds like it'll have the vignetting correction for all their lenses working, but I'm not sure how this'll work with the C series. Does the vignetting correction work with the C200s RAW files?

I took the back plastic off and did some tests.....unfortunately no change in the dark vignetting in the corners due to the plastic. The biggest difference maker was stopping down the lens. However one interesting, but perhaps useless finding is that when I took the back plastic off, the vignetting of the lens had a much more even falloff across both sides of the lens as you can see in the screen grab below the video of the Lumetri scopes from premiere

As much as I like the sharpness of the Sigma lenses, I'm sticking with Canon. Too many limitations on the Sigmas, the value equation isn't there for me.

I saw that announcement as well, but it didn't include the cinema cameras. I wish it did.

I would be interested to know whether the C200 RAW files includes Canon's exposure compensation at all. My experience with other cameras has shown that RAW shooting and some of the higher bit rate codecs tend to exclude things like exposure compensation and CA correction on Canon cameras.
 
Has anyone used the Tamron 15-30 2.8? I may rent one to test it out because I'm very interested in how the autofocus and the image stabilization behave on the C200.
 
Just did some tests with the Tamron 15-30 2.8 & the Tamron 24-70 2.8 at the local rental house and the lens wouldn't talk to the camera. Couldn't change the aperture and autofocus and vibration control were unresponsive.

I imagine this could be fixed with a firmware update, but just an FYI.
 
I didn't see much love here for the 24-70 which was my go to lens for fs7 with metabones speedbooster (FF). Not perfect on s35 but I assume it works well with dpaf?

Most of the people I know have the 24-70 in their kit. I think it is the perfect lens for shooting people. Maybe it is just too boring to mention.
 
Really liking 35mm F2 IS! Fast autofocus, pleasant bokeh and pretty quiet for the most part. Will have to do more tests, but so far it seems perfect companion for C200
 
One of my favourite lenses (on my Sony FS5, via various Metabones adaptors, or C100 DPAF). Manual focus ring is decent and smooth too.
 
How has everyone's expierience been with the autofocus on the Sigma 18-35 1.8 Art Lens & the Sigma 50-100 1.8 Art Lens?

I used the 18-35 on a studio shoot a few weeks ago with a lens that I'm 99.9% sure has not had it's firmware updated and the facial recognition box tracked perfectly on our talent during a very slow dolly in, but when I watched the footage I'd say about 25% of the move was soft focus - it seemed even though the camera was moving so slowly that the autofocus was lagging behind. This was probably at a f/2 or f/2.8.

I think if I was confident that both lenses would hold auto focus well at f/2, I'd buy both in a heartbeat and make them my go-to studio/interview lenses.
 
I have the Sigma 18-35 1.8 with its latest firmware. I can't speak to tracking a dolly shot but I shot some interviews on C200 with that lens this past weekend and it held it's own very well. I think the focus was probably slower than a native Canon lens but it felt like a more natural focus pull.

I would definitely rent one and make sure it has the latest firmware before pulling the trigger but I've been very happy with all my Sigma Art lenses on the C200.

I've seen some very nicely shot footage with the 18-35mm 1.8, great lens in the right hands.
 
I rented an 18-35 for a bit to play with and will likely just buy one. It's a great little lens. I was using it on a C300 Mk II, but I'd imagine it'll work the same on the C200. AF isn't as "snappy" as a Canon lens (especially STM) but it does the job.

I'd love to be able to stop carrying 28mm and 35mm primes and have a wider starting point. It'll get a lot of use on both my C200 and 5D Mark IV in 4K mode.
 
I just picked up the 70-200ll F4 for use on my C300Mk2. This lens is much lighter than the 2.8 version and can be used hand held with the camera in striupped down more - hand grip no rig- very easily. The DPAF in combo with this less is really fast and virtually silent . The lens is tack sharp and now I find myself questioning why I own the 2.8 70-200.
 
It all depends on what you shoot and how you shoot it. I've actually been having some fun with my cheapo EF-S 10-18 4.5-5.6 STM IS. It's a cheap lens but the wideness of the FOV at around 12mm let's you get some interesting shots, good for handheld without a gimbal or for shooting in tight confines. It's not particularly sharp but usable and it's pretty slow but it's clean and the images look pleasant with good light levels.
