6dm2 lens compatibility

[Maggieleigh44]

Hello,

I just purchased the 6DM2 and want to know if the Sigma DG 150-500 (2008) 1:5-6:3 APO HSM is compatibile.  I previously used it on my crop body, but don't want to try it on my full frame without knowing if it's compatible.  I found a couple of websites that say it is compatible.  Just confirming to be on the safe side.

Thanks

How often would you be able to update any lens?  How often have you heard of Canon releasing new firmware for lenses?

I am not sure whether all Canon lenses can even accept firmware updates.

Up until a week ago I'd never heard of it. Then Mike Sowsun explained that some recent Canon cameras have the ability to perform firmware updates on Canon lenses. Which raises, I guess you'd have to admit, the possibility that Canon might actually release updated firmware.

The question isn't silly. If Canon makes changes to its cameras that confuse 3rd-party lenses (which seems to happen with some regularity), isn't it likely that sooner or later such a change will also confuse older Canon lenses?

If only there were an announcement section on this board where you caould see which lenses have firmware updates! Then you could look and see that Canon just released updates to 3 EF-M lenses.

I have never heard of a firmware update for an "L" lens.  Doesn't mean there isn't any but I never heard of any.  Since CPS knows what lenses I have and I receive regular emails from Canon, it would be nice if some notification was made.

The EF 24-105mm f/4L IS II USM just recently had a firmware update.   I think it is the only L lens to ever have a user installed update available.

It was posted in the "Announcements" area of theis forum:  New Firmware: EF 24-105mm f/4L IS II USM

Here is a direct link to the Canon USA support page:  EF24-105mm f/4L IS II USM Firmware Version 2.0.0 [Windows]

Changes in firmware: Firmware Version 2.0.0 incorporates the following enhancement: Support for the "panning" scene mode with the EOS M5/EOS M6 has been added. The Panning scene mode reduces subject blurring and blurs the background when the lens is mounted to the EOS M5/EOS M6. The EF-EOS M Mount Adapter is required to use
this lens with the EOS M5 and EOS M6.

Doesn't help me because I don't have that lens or any mirrorless cameras.  But now that you brought it to my attention I think I do remember seeing that.
