Canon 40mm pancake firmware update

[Pinchers of Peril]

So I just received me new 40mm pancake from Adorama. I remember seeing that there was a firmware update for this lens but now I can't find the thread about this. Is there any way to know if my lens has the updated or old firmware? What problems do the new firmware address and how do I update firmware for a lens? I have updated firmware for my camera before, but never for a lens. Thanks in advance.

You need a 2012 or later body. If you just bought it, it's almost certainly updated.

All the production lenses were updated long ago. You can only update them while attached to newer cameras like the 5D MK III, otherwise, they must go to be serviced.

Is the lens giving you a problem?? I didn't bother to have mine updated, it worked fine.

The Canon bulletin is here:

The firmware update is on the canon web site. http://www.usa.canon.com/cusa/consumer/products/cameras/ef_lens_lineup/ef_40mm_f_2_8_stm#DriversAndSoftware

Great, thank you guys for the quick response. The third digit on my serial number is a "3" so I think it is already updated. On an unrelated note, does your pancake lens feel really really tight when you attach it to your camera. I shoot with a 5DIII and I feel quite a bit of resistance when mounting the lens. It functions fine, but I've never had any of my other lenses feel so "tight."

Yeah, my 40mm also has a really tight mount
