Canon EF 40mm f/2.8 STM Product Advisory

Canon EF 40mm f/2.8 STM Product Advisory

To Users of the EF40mm f/2.8 STM Interchangeable Lens for Canon Digital SLR Cameras
Thank you for using Canon products.

It has been confirmed that the autofocusing function of the EF40mm f/2.8 STM lens, which was released in June 2012, may not operate correctly.

The details of this phenomenon are described below.

Affected Product
EF40mm f/2.8 STM

Phenomenon|
If pressure is applied to the lens barrel while the lens is mounted to the camera (pressure can be applied even while attaching the lens cap or while carrying the camera with the lens attached in a bag), the autofocusing function of the lens may stop working.

*This phenomenon does not occur during normal shooting.

*This phenomenon does not result in a malfunction of the lens.

Workaround
When the above phenomenon occurs, detach and reattach the lens, or remove and reinsert the camera battery to restore the operations.

Market Support
The firmware to address this phenomenon will be available for download in late August, 2012.

Once this firmware is ready, we will make an announcement on our Web site.

My Canon EOS-1D X Has Arrived!

Finally eh?
My Canon EOS-1D X has finally arrived! I think I actually preordered it before it was announced.

First Impressions?
Not many yet. I have touched this camera countless times at various photography trade shows, so nothing is really new. It is really nice to actually be able to put a card into one of the slots and save some images.

I will be using this camera pretty hard for the next little while and will let you know what I think.

Availability in the United States should come on Thursday or Friday, I’ve confirmed this with B&H.

Canon EF 40mm f/2.8 STM Quick Review

Canon EF 40mm f/2.8 STM Quick Review

From Roger at LensRentals.com
As Roger does, he received the new Canon EF 40mm f/2.8 STM lens and had to immediately put it through the paces.

Roger did some computer aided tests to check the sharpness at MTF 50 and compared it with other higher end Canon zoom lenses, and it turns out the little pancake outperformed them in some areas.

Roger’s Conclusion

Overall, though, I’m extremely impressed. I’d be impressed if a lens this size and price was just decent, but this one is excellent. I might as well go ahead and get in trouble with the business manager: if you think you want this lens, just go ahead and buy it. At this price, unless some of the more thorough reviewers find something I missed on this quick overview, you can’t go wrong.
