This firmware allows compatibility with Canon’s in-camera Lens Aberration Correction function to enable correction matching the optical characteristics of each lens. It also corrects the phenomenon that abnormal images appear or operation errors occur when the function is enabled. This firmware also corrects the phenomenon whereby the continuous shooting speed decreases in certain combinations with some cameras when used with the 14-24mm F2.8 DG HSM | Art for Canon, and the phenomenon whereby the AF speed occasionally becomes unstable when used with the 100-400mm F5-6.3 DG OS HSM | Contemporary for Canon.</p>
<p>For customers who own the SIGMA USB DOCK and applicable products listed below, please update the firmware via SIGMA Optimization Pro. Before updating the firmware using the SIGMA USB DOCK, please ensure to update SIGMA Optimization Pro to Ver. 1.4.1 or later for Windows, and Ver. 1.4.0 or later for Macintosh.</p>

So is there any reasonable way to update without the dock? Like putting update on cd card or hooking lens up to a computer?
I don't think there is....

Have you any close by friends with the dock, or could you talk your local camera store into updating it? It only takes a few seconds to run the update....

most local shops will let you do it at their store if you bought there.

they're not expensive and you might find it dirt cheap on ebay

You just might be able to go into a local camera shop (if you have one relatively convenient to your location - hopefully) and have them hook your lens(es) up to a Sigma Dock and have them run the upgrade for you - it may run you a small fee for such a service. I have no idea really. But may be an option. Or mail to Sigma corp but I would rather spring for the $59USD for the Dock. Especially if I had more than one Sigma lens and/or considering getting any more Sigma lenses.

Sigma and Tamron both were very, very smart to introduce devices to allow owner's to upgrade lenses to future proof them to a certain extent. Which would also help the resale value of the compatible lenses (for the same reason). Sorry, digressed here just a little.

Sorry Don...I hadn't read your post before I responded. GREAT ADVICE by the way. On this note, does the OP'er have any local camera clubs where they could ask a member?

I own 2 Sigma Art lenses and ALWAYS update them. That said, I've NEVER seem any change in performance. And a used dock is like $40 on ebay.

I have a dock, no lens, it went away last Monday. I kept it in the event I find a Sigma lens I want, but that seems unlikely.
