FAST <20mm lenses for Canon EF mount?

[Stephen Pruitt]

Hi all. . .

We're constantly in need of fast glass for our films, but our widest current fast lens is the 24mm f1.4L. Are there any under f2.0 EF-mount wide-angle lenses (wider than 24mm, at least) that really hold up well wide-open in 4K?

Thanks.

i was considering sigma, they have some around 24-20 at 1.8-1.4. i like sigma alternatives. i am a fan of their 10-20 3.5 and had their 12-24 4.5-4.6, it was just bit a tad too slow for video, but good for photos.

I should probably try that Sigma, but the reports are so darn uneven. A lot of people say it is too soft to use wide open.

[James McLellan]

From the sample I looked at it was a non starter. No need to try it. Almost as bad as the 18-55 kit lens for sharpness.

This is the lens that confuses me:

Why not something similar for 1.6 crop/4k? Can someone explain what the deal is here?

For whatever reason 20mm and 18mm primes became unpopular in "stills" world during the 80s and 90s. However I adore both lengths on FF35, even though they are pretty wide. Sigma is the fastest still 20mm lens at f/1.8. There's an Olympus 21mm f/2 that's older and considered very compact for what it is and it can be adapted to EF very easily. Other than that it's Canon and Nikon with 20mm f/2.8 and Nikon also has a 18mm f/2.8 as well. Canon is going to expand their Cinema Primes at some point and add a wider lens and longer lens at both ends, but we could be waiting a while. I like faster primes and this has also been sort of a point of frustration for me.

In cinematography PL 18mm is a pretty standard length and their are a few options out there ranging wildly in price. But that's PL and not really EF. I'm putting dough together to get some sort of PL package. RPP are up there on my list as they are pretty much the best bang for the buck.

[Stephen Pruitt]

Yeah, but the trouble with those RPP is that they are all really slow for our purposes. I can't tell you how often we have to shoot at f1.2, f1.4, etc.

I'd really like that Sigma 20 f1.4 if it were sharp, but, as noted above, it's probably a non-starter on that score wide-open.

Thanks guys.

Whoa, James. . . that does look like a nice lens. Can a 4/3rds lens be fitted to a Canon EF mount and actually cover 4K? It if was sharp and would fit, I'd buy it yesterday.

[Mark Pedersen]

You are fighting physics/cost to create wide lenses faster than 2.8.

We are, indeed, Mark. But I'd be more than happy to pay a "reasonable" amount for a fast f1.4 20mm Canon L-series lens.
