1DIII and Sigma WA lenses...

I just bought myself a 1DIII to use as my primary sports-shooting body. I've already got a 7D, which does a great job, but I know the focus-capture speed is better, and the frame rate is higher, and they're pretty reasonable now, plus it operates a lot like the 7D, so no huge learning curve.

Running through my various lenses with the 1DIII, I see that I'm getting vignetting with my Sigma 10-20 and 17-70 lenses. I can pretty much eliminate it by changing the aspect ratio to 4:5, and it doesn't concern me much, as it's normally used with a 70-200L, a 100-400L, or a 100mm prime, but I'd like to know if this is common? The APS-H sensor certainly contributes to the vignetting, but I'm wondering if there's something about the Sigma construction that helps create the vignetting?

Regards!
Don

I experienced pretty severe vignetting with the 10-20 at all focal lengths, something about the design seems to keep the image circle at the same radius. The 8-16 doesn't have this problem and is usable from 11mm.

Thanks, Mike. I might have to investigate the 8-16...

The Tokina 11-16 f2.8 works from 12mm onwards. The Sigma 12-24 works on a FF body, so it would work on the APS-H as well.

Thanks, TeamSpeed. I'll have to do some in-store trials, I suppose. Meanwhile, I'll just change the aspect ratio if it REALLY comes up. I don't do a lot of landscape work, nor wide or UW in general, so I doubt I'll worry about it much.

It is due to the construction of the lenses: they are constructed to project an image to cover an APS-C sized sensor, not the larger APS-H sized sensor. That you are able to use them as much as you are is probably something to be thankful for rather than expectant of.

If you have a 1.4 Teleconverter, you can use the Sigma 10-20mm without any significant
Vignetting. See this thread for examples https://photography-on-the.net …&highlight=sigm​a+10-20+1d

I forgot all about that one, Evan, good suggestion.

I use a Sigma 8-16mm on my 1DMkIII ... from about 12mm and longer, the vignetting is so slight that it does not present a problem. The image below is not edited for vignetting. That's the equivalent of about 15-16mm on a full frame.

You could use 11mm (~14mm) with some minor work on the corners (first image).

thanks, Maxdave! That's another consideration...

I use the 8-16 also. However, mine is a bit of a different case. I was talking to my dad one day about how the attached lens hood gets in the way of the photos and causes more vignetting than necessary. He is a mechanic, not a photographer, and thought it would be a nice surprise to show me he ground down the lens good with his vacuum grinder (preventing metal dust from scratching lens). Honestly, I would have never done it mainly because I doubt I could sell the lens for much now and I have a tendency to swap lenses quite a bit since they hold value buying used.

The results are nice tho. I do not have any real shots, because I portion of my pictures due to a recent HD crash / recall, including my scenery folder. But here are some quick test shots. I'm not saying I recommend doing this, just showing it can be done.

All Handheld.

8mm

Reads 8mm but is more like 8.5mm & f/stop reads f/5.0 wide open not f/4.5

Also, those are with no processing whatsoever. No lens correction at all. I can post more with a tripod showing FoV difference and lens correction if anyone wants. I didn't bother because I imagine no one would be daring enough to try this. I sure wouldn't be.

Matt, I'd be interested to see a picture of the lens with the modifications made.

Here you go. The Top (seen on right) is shorter than bottom. I believe this was done on purpose. The process my dad did was take a photo, grind, repeat. So I think the top needed more than the bottom off, tho it could have just ended up this way by mistake (i.e. he took more off on the top than needed). I also believe the biggest significance was the corners being taken in ( the parts of the hood that were already the shortest).

I'd like to get some black matte paint to touch it up, but haven't look into finding a sigma matching paint.

Clickable for full size if you need close inspection.
