Sigma 10-20mm for Canon 10D - DPChallenge Forums

07/20/2006 10:56:29 AM · #1

Ok, I have a Canon 10D, and I've been laboring over choosing a wide-angle zoom. I think I have settled on the Sigma Zoom Super Wide Angle 10-20mm f/4-5.6 EX DC HSM Autofocus Lens for Canon Digital SLR Cameras.

Good choice?????

It's wider than the tokina 12-24 and cheaper than the canon 10-22 - but it is slower than either. 5.6 at 20mm? The tokina is f4 (a full stop faster) and the canon is 4.5 (2/3 stop faster).

for landscapes it may never matter, but for interior shots it may be a big deal.

Hmmm, I've been considering this one too. The Canon is too pricy, I don't know enough about Tokina to trust them, and the Tamron has even worse apps.

Be interested to know what others think, too.

I have the Tokina 12-24 and use it on my 10D a lot. I love it. I'd go so far as to say it's my favorite lens of all the ones I own. Then again, what do I know. ;)

It won't... if you are using a tripod and your subject(s) are not moving. Otherwise, you will find that it will be difficult to get enough light to expose properly and keep shutter speed up far enough to avoid subject blur.
Flash is problematic with ultra-wides; it takes some work to make them cover such a wide angle.

You are correct, it will not work.

So I read a review of the Tokina lens, and it said it had "CA problems." What is that??

CA is chromatic aberration - shoto a backlit subject, like a winter tree against the sky, and you'll see purple fringing.

The canon 50 1.8 does this as well and no one complains about it.

I have not heard of that on the tokina though.
let me go look at some shots with the 12-24 and i'll see if i see any CA. (i borrowed the lens back in march)

I have had no CA problems with my lens, fwiw.

Well, here is what I will be using it for. I should have mentioned this first. I shoot for a local magazine, and lately we have been doing more and more stories on interior design. I have been shooting in alot of homes and apartments. I use a tripod and longer shutter speeds since I usually have to depend on available lighting.

I need to choose a lens that will serve me well when shooting these.

On the CA front...
here are two shots, one wit CA and one without (F8 and 6.3 respectively), same place, time, etc.

I enlarged the CA issue to 100%, with the entire image as an inset.

As to the OP - since you are using a tripod then speed is not an issue.

Prof, that's not actually CA... it's blooming, and caused by extreme overxposure of the background vs. the foreground. The key is that the fringe is magenta all the way 'round. With CA, you get fringes of complimentary colors on opposite facing edges.
The reason that is important to this discussion is that the blooming is not really a function of the lens. It tends to show up with fast lenses shot wide open in daylight, but that's only because that situation creates a perfect opportunity for the issue to show up.

I have to me more carefull! in a moment of what can only be called madness I popped my 10-22 on the 1dMKIIn! yes, it fits but luckily I realised what I was doing before I tripped the shutter. It will fit but actuation will probably shatter the mirror

Because EF-S lenses are made so that the optics can get closer to the sensor in smaller frame digital cameras. In full frame cameras you might hear a crunch! lol.

I love my sigma. Some days I have a bit of barrel distortion, but nothing I cant fix. Ive never had CA problems.
