To the Users of the EF300mm f/2.8L IS II USM, EF400mm f/2.8L IS II USM, EF500mm f/4L IS II USM, and EF600mm f/4L IS II USM Interchangeable Lenses for Canon Digital SLR Cameras

Thank you for using Canon products.

Canon has released a firmware update for EF300mm f/2.8L IS II USM, EF400mm F2.8L IS II USM, EF500mm f/4L IS II USM and EF600mm f/4L IS II USM lenses. This firmware update will be performed by Canon Service Centers. Please contact us using the contact information listed at the bottom of this page.

Firmware changes:
Firmware Version 1.1.1 incorporates the following enhancement:

1. Changes the control algorithm of the focus drive, and enhances the drive’s responsiveness for more precise focus and adjustments. In particular, the new firmware enhances the AI servo AF capability of the lenses to track objects that move irregularly in sports events, such as soccer or rugby.

Affected Products:
Firmware Version 1.1.1 is for lenses with Firmware Version 1.0.0. If the lens’ firmware is already Version 1.1.1, it is not necessary to update the firmware. The serial numbers (10 digits) of the lenses equipped with Firmware Version 1.0.0 are as follows:

EF300mm f/2.8L IS II USM:
The third digit in the serial number is either 0, 1, 2, or 3 (xx0xxxxxxx, xx1xxxxxxx, xx2xxxxxxx, xx3xxxxxxx).

EF400mm f/2.8L IS II USM:
The third digit in the serial number is either 0, 1, 2, or 3 (xx0xxxxxxx, xx1xxxxxxx, xx2xxxxxxx, xx3xxxxxxx).

EF500mm f/4L IS II USM
The third digit in the serial number is 0 (xx0xxxxxxx).

EF600mm f/4L IS II USM
The third digit in the serial number is 0 (xx0xxxxxxx).

Lenses with serial numbers other than those listed above are equipped with Firmware Version 1.1.1 or later.

Good thing that Canon is doing this.
On the other hand.....what is going on with the Quality Assurance at Canon?

I wouldn't necessarily call it a quality assurance issue. Canon has just developed a brand new 61pt AF system and drive in their new pro bodies that has some advanced capabilities not previously used. Seeing as all of these lenses were designed and announced well before the 1D X was even announced, let alone released, its not surprising they have an update to these lenses that would fully support their new AF system.

+1.  At least Canon is willing to update/fix these issues when new technologies/products are introduced.  3rd party manufactuers can also run into these issues as well, but how often would they acknowledge and fix the issue?

You have a point.

How would one update the firmware on those lenses? Via an on-lens USB port?

According to Canon Rumor's original post, you have to take the lenses to a certified Canon Service Center:

This firmware update will be performed by Canon Service Centers. Please contact us using the contact information listed at the bottom of this page.

I would assume they have a special lens mount on a special device that attaches to a computer or other firmware update system. Mount the lens to such a thing, and it could be updated through its standard contacts that drive IS, AF, and allow the camera to control the aperture.

Is the upgrade free?    What about the 1.4xiii and 2.0xiii?  They have processors too...

Canon really needs to find a way for us to update our own lens....  I don't care to have my $10k lens being shipped out for weeks..

Good and yet if after that many delays it seems a bit hard to fathom. Maybe now that it is in tons of real hands at the Olympics they are finally getting proper testing? A bit bizarre.

Am I the only person here that finds it incredible that a LENS has a firmware update!?  I thought they were just a bunch of glass in a tube, but I guess there is more to it than "meets the eye"... 

Bad pun, sorry.

There must be some electronics there to communicate with the camera and activate USM & IS.

No, it's not free. I visited my local Canon service with my lens today and they were not able to download new firmware from Canon servers. New 40mm pancake will probably need update even more.

Are they using a special "machine" to do the lens update, or can you just do it like you would your camera body?

Does anyone know if this update would only benefit the owners of the 1DX.  I have a 5d mark iii and if the firmware update wouldn't add anything for me I would rather not send it in for a few weeks.

Oh, bother. I'd really rather not have to deal with shipping that beast...methinks I'll wait until I sign up for CPS.
