Sigma 8-16mm on 80D? Anyone?

I have a Sigma 12-24 II that is just wonderful on my 6D. I am currently down-sizing gear and this lens is the last thing keeping me in full frame. The thought is to trade/sell it for a Sigma 8-16mm lens. The problem? My 12-24 II just refuses to focus accurately or consistently on my 80D. Yes, I've tried MFA, twice. Total fail. In another thread, someone suggested the 12-24 may be old enough that Sigma has not re-vamped its AF for the newer 80D. The 8-16 is even older. I am afraid it won't focus on my 80D. As expected, 80D/12-24 works in LiveView, but I don't want to be committed to that.

Does anyone use the Sigma 8-16mm on an 80D? Does it focus properly? I am especially concerned at and/or close to MFD. Also taking suggestions for an alternative lens. Thanks.

EDIT:
I've managed to find a bunch of nice photos made with the 80D/8-16. No mention of focus with any of them. Perhaps I need to consider the possibility of LiveView.

Do you need the 8mm difference from 10mm? Because there isn’t much else wider apart from fisheye type options.

8mm is just a bit wider on apsc than 12mm on FF. I like and use the 12mm end of my 12-24 on the 6D.

I'm not sure what you are referring to with 10mm. As close as I can get to 10mm is my Tokina 11-20mm. There is a huge difference between 8mm and 11mm on apsc. Roughly the same a 12mm to 17mm on FF.

I just sold the Sigma 15mm FE and Rokinon 12mm FE because I like the rectilinear projection of the Sigma 12-24 much better. The 15mm FE is about as wide as the Sigma at 12mm.

Sadly, I can't help regarding the sigma, but my Canon 10-22 has proven itself to be one of my all time favorite lenses. I know you were asking about the Sigma, just throwing more option out there.

Not that is specifically addresses a focusing issue, but do you have the latest firmware (1.02)? Even if you do, it might also be worthwhile to reflash the firmware. There are more and more cases in the forums of strange issues being taken care of by a reflash.

You can download it at https://www.usa.canon.​com ...subtab=downloads-firmware (external link).

Just checked. I do have 1.02 installed. The focus issue with the 12-24 on the 80D is just about irrelevant. It isn't wide enough. Besides, I've already got the Tokina 11-20, which does focus, but again, isn't wide enough.

I'm looking for confirmation that PDAF works with the 80D/8-16 combo.

I am not sure how there can really be a focusing issue with this lens, as everything would be in focus. The DOF of such wide angles, even on APS-C, is huge, and it would be difficult to do anything to adjust focusing, even AFMA wouldn't add anything to the equation really.

True... enough. Most of my stuff with lenses this wide is f/5.6-8, and focused at 3'. 2' to infinity looks good like that. I used a Rokinon 12mm FE with good effect like that. Problem is that from time to time, I like to use the lens wide open, focused at or near MFD. I get by with LiveView, I suppose, but I'm not used to it. PDAF that works would be handy.

I am primarily concerned because the 80D cannot focus the 12-24II. The 8-16 is older. Legitimate concern?

I guess my point is that it really doesn’t matter how well the focusing is, if you need 8mm wide on crop, you really only have one option in the 8-16 especially if you want rectilinear.

Well said. I hadn't thought of that. It is the only option.

My SL2 has no issues with the 8-16. I am not sure whether that helps you though. :) I don't think the 7D2 has any issues either.

EDIT: Nope, works on all 3 of the cameras.

Thanks. Helpful. SL2 is newer than 80D. Should be fine.

what exactly is your issue with the 12-24mm on the 80D? does it not even achieve focus, or is the focus just off?

i've never heard of any issues with the 8-16mm, works fine on my 70D...but i've also never really heard of any issues with the 12-24mm either...so maybe it's just your lens?

Lens is perfect on 6d. Erratic on 80d. Mfa does not help.

Works on the 5d4 as well, but as a 16mm prime...
