Sigma Primes?

[Terry VerHaar]

I was wondering if anyone has used - and would, or would not, recommend - the Sigma primes as an alternative to Canon L glass. Specifically wondering about the 50 and the 85. Normally I'd assume that because they are so inexpensive they couldn't possibly be competitive, but the Tokina 11-16 has blown that theory. :-)

Thanks for any input.

many of them are competitive, even for the price - the question is - is the electronic aperture supported on RED's list? where does one find that list anyway, I know I've seen it.

www.fredmiranda.com is a great place to find comparative glass reviews for still glass, in terms of comparing sharpness, color rendering, etc. also a good place to buy used glass in great shape - it's one of those glass junky sites where people buy to try and then sell.

The 85mm f/1.4 is pretty nice. I like the images off the Canon 85mm f/1.2L a bit more though. It's just a better piece of glass. More contrast, pleasing out of focus effect, a bit sharper, etc.. Hate the fly by wire design though.

I have no experience with the Sigma 50mm. But I do own and like the 50mm f/1.2 a lot. Pairs well with the 24mm f/1.4L, 35mm f/1.4L, and 85mm f/1.2L.

I'd be curious to see how the Sigma 30mm f/1.4 holds up. Haven't had the chance to use one yet. Might give the Sigma 20mm f/1.8 another shot too.

i would like to try 20mm 1.8 vs 24mm 1.4 there is huge price difference between these.Andrew Walker was using 20mm 1.8 on red one

The Sigma 50mm 1.4 was better than the Canon 1.4 when I tested (Wide open and to about f4)... linted to a sample of 1 each so YMMV...

that said I did try a wide Sigma ( 24mm 1.8???) and it was dreadfull... bought the Canon 24mm f1.4 mrk2 instead and it is ok (not great but ok). May just have been a bad sample...

Phil - Thanks for the input. Not sure what you mean by "fly by wire design."

Meryem - Good point about the AF support. Have to look that up.

EDIT: According to this post by Jarred, they are supported:

yes they are supported Terry.there is a huge lens list by Red that is supported on canon mounts but cant find it right now.

The list is in this thread - Canons on the first post, Sigma later. There may be another where they are all listed but I didn't find that one just now.

I have the sigma 20mm 1.8. Worse piece of glass I own...I wish I would have bought a different sigma prime before I bought this because i have a foul taste in my mouth for sigma now. The more you close off aperture the more foggy the image looks, all clarity is lost... When wide open, what is in focus is pretty clear, but areas outside of focus are...foggy looking....not just blurry, but foggy...very unappealing.

I have to agree with the 20mm 1.8 sigma....it's pretty bad....almost unusable at certain f-stops...
