What Cinema Lense for a Canon C100

With any cine camera you are going to want a wide lens, a normal lens, and a short telephoto lens. For a Super35 format camera like your C100 this translates to a...

Are Rokinon Primes Right For You?

I also have a C100 and i would personally recommend getting the Sigma Art 18-35mm f/1.8

Although it's not a cine lens, it's just so versatile of a lens. I use it all the time.

At $799, it's not cheap, but it's like having two prime lenses in one, and that will save you money in the long run.

You can do a majority of your work with just this one lens.

After that, if you are looking to get an additional lens, I'd recommend either a Rokinon 50mm T1.5 or a Rokinon 85mm T1.5

I just bought Rokinons 35mm and 85mm and compared with Canon's L equivalents: 35mm and 85mm Mk2.

I dropped a screenshot showing how the 85mm's compare -- I cant tell the difference:

I shoot only with two focal lengths: 85mm for majority of time, and some establishing shots on 35mm.

Now, Canon' duo: $2.5k used on Craigslist. Rokinon's new: $1.1k. So, selling my Canon glass & metabones adapter. Rokinon's e-mounts will probably see me through the next 5 years!

The 24-105 f/4L is a champion on this camera. Also - bang for the buck - Ef-s lenses put out surprisingly great images on the C100 as well. I've shot with the Ef-s 17-55 f/2.8, 15-85 F/4-5.6, and 18-135 f/4-5.6 and would recommend any of those. I do a lot of small/mid sized indoor event shooting and so these different zoom focal lengths have been really helpful. And even though a lot of these lenses aren't that fast, the ISO on the C100 can go bonkers high and still churn out beautiful and usable images.

I'd second Ian, too. The Sigma art zooms are fast enough to be two in ones. The new 50-100 and the 18-35 f/1.8's seem like a solid, competitive price.

Now this post is from a while ago and you've probably got your new kit put together, but those are my two cents!
