I think its a bit hard to tell at this size.

Those are obviously very nice. Lens calibrated?, PP altered?

Hi! I'm new but I've been stalking this thread for a while and I really appreciate the reviews and pictures everyone has shared.

About a month ago, I bought the Canon 50mm 1.4 for my Canon T4i (cropped sensor). I use the T4i for a lot of video. I knew that 50mm would be like 85mm on my camera, but I didn't think that would be an issue.

It was.

So I researched the 30mm option and found this thread extremely useful. I'm returning my Canon 50mm and getting the Sigma 30mm 1.4 Art.

I just found the video review from searching YouTube (external link). I joined the forums to share what I found helpful, too.

Welcome. Enjoy your new lens. I have the previous version of the Sigma 30mm and love it. The new version is reportedly much better! A 30mm lens on a crop body is the closest thing to a single focal length general purpose lens. Your 50mm would serve that same purpose on a FF body.

1dmk2, so no MA or calibration. Not much pp as I don't know PS. Import into LR, mostly defaults.

Nice pics, bobbyz. The "old" Sigma 30 1.4 was pretty good in the center as your photos show - but it went downhill fast towards the edges. This is where the 30mm 1.4 Art should be improved - and if you believe Lenstip it is improved, esp. when stopped own to 2.0 or 2.8.

We need a few landscape type photos with in focus details edge to edge to check this out. I'd volunteer except my lens is at Sigma being calibrated. :(

You have the new A lens? Did you test first or send it right to calibration?

Here's another wide open SOOC with 60D, with just the light in the room. Can someone tell me if this looks good? Can you tell from this if I would gain anything from having it calibrated?

I have the old lens, and it is a somewhat soft at the edges at f/1.4. Its improves significantly as you stop down, although it's never quite as sharp as in the center. While I generally agree with your statement, saying "it went downhill fast towards the edges" makes the lens sound much worse than it is.

OK so which f1.4 is not soft on the edges. Not sure what you guys shoot at f1.4 and need to look at edges.:)

We're on the same page here. I was just commenting that the previous Sigma f/1.4 wasn't as bad as his comment suggested.

Sorry, didn't mean to offend ... but I thought that the edge performance of the old Sigma 30 1.4 was the main complaint about the lens. (See review at photozone as an example.) That said, in the majority of pictures above the edge performance is irrelevant, and the results are excellent.

From the MTF charts published by Sigma and early test data from lenstip, edge performance of the new 30mm 1.4 Art is improved - not as good as the full frame 35mm 1.4, but improved. But if you are creating photos like the CK bottle or portraits above you may never be able to tell the difference.

Actually, the Sigma 35mm 1.4 is pretty amazing in that the edges are quite good even wide open. But like you said, will I ever be shooting landscapes at 1.4? My sources say no. :)
