Canon 28mm 1.8, Sigma 30mm 1.4 or canon 24mm 2.8?

I'm very, very happy with my Canon 28 f1.8. It's been fan-freaking-tastic.

Sigma 30mm 1.4 all your life! If you get a good copy it is wonderful ! I love mine!

I've had VERY bad experience with a 3rd party lense, and pretty much am very reluctant to trust Sigma and Tamron, since iv seen them crumble for no reason.

but also herd the contrary where they do get a "good copy" and they produce amazing results.

But im happy with my 28mm f1.8 USM

Sigma 30mm.

It's a great lens. Yes it does have its faults with quality control, but Sigma has been great fixing these problems if you choose to send it in if you're under warranty.

If it weren't for Sigma and their focus issues I'd say Sigma all the way. But that's not the case...

My Sigma 30mm was pretty much perfect right out of the box. I haven't had time to use it much since buying my 5D, but want to give it some time on my 40D soon.

Thats the thing though, an awful lot of people end up haivng to recalibrate there sigma's because of focusing issues

Still not sure what id go for though...

I have the same choice to make. I'm currently going more for the Sigma 30 1.4 due to the slightly faster aperture and reports that it is quite a bit sharper than the Canon 28 1.8 wide open, which is where I plan to use it most.

I used to own a Canon 28mm f/1.8 and it was a great great lens on my 40d. I have since traded it away in my pursuit of a 24-70mmL.

I have recently purchased a used Sigma 30mm f/1.4 (in transit) and hope it lives up/bypasses my past experience from my old 28mm f/1.8.

We will see

I feel the 3rd party lenses get a much worse reputation then they deserve. People are way more likely to come complain about something than come praise something that works as it should.

love my sig 30 1.4

I had a sigma 30mm and it was pretty great. I bought it used, so it was tested already and I lucked out and ended up with a good one. Now, on my 5Dii I have the Canon 28 1.8 and love it. It's AF is really great, right up there with the 85 1.8 and 100 2.0, as is the build quality. Color is slightly lacking contrast wide open, but much better by 2.8. Great lens and I like that it focuses closer than the Sigma.

i have the sigma 30mm and its on my 50D 95% of the time.. its fairly sharp wide open, but really shines at f/2.0.. focus is fast and spot on..

sorry to resurrect the old thread, but I want to hear more opinions between Sigma 30mm 1.4 and Canon's 28mm 1.8. Fast autofocus is important to me, especially in low light, I know both feature HSM and USM, but for Canon's 28mm is it Ring Autofocus USM or Micro Autofocus USM (like 50mm F/1.4 which is not as fast as true Ring Autofocus USM)? I have a Tamron 17-50 (Promaster rebadged) which is very very good, but I am trying to see if I can find something even better at the same price range with better low light performance and separation. For my typical low light shots, the range of 28-35mm crop or 50mm full frame would be ideal. I am gonna use it on T1i
