New Canon 5D Mark III with 24-105mm f/4L IS USM AF Lens


The new Canon 5D Mark III is the updated version of a camera that became not only a go-to full frame DSLR for professional photographers and serious enthusiasts, but also a surprisingly capable, affordable and relatively tiny HD video camera for cutting-edge video productions. Cinematographers, even those operating at the level of episodic television, were suddenly able to capture gorgeous 1920 x 1080 video by employing the shallow depth of field and the broad choice of lenses that a large-sensor DSLR camera can offer. This Mark III version addresses some of the few shortcomings of the Mark II and offers a long list of other welcome enhancements, from the larger viewfinder to the updated internal cleaning system.

A revamped AF system has 61 points of autofocus, helping the 5D Mark III perform better in many situations, including low light. On that note, the DSLR now features wider ISO sensitivity of 100-25600 in normal mode. The new DIGIC 5+ image processor bolsters shooting speed, write time, noise reduction and more. Video recording is also improved: There’s a new I-frame-only mode for lighter compression. Longer clip recording times are possible, too.

I bought my Canon 5D Mark III last August (body only) and a Tamron 24-70 2.8 lens. My photos information register a different lens - sigma 24-70.... instead of the Tamron. Could you please advise me on this. Is there something wrong with the Camera or the lens?


It's a great camera, I'm seriously considering buying one myself... but there is one little issue with the video. He states that with the EF mount, it will use any lens that fits any other Canon DSLR camera. Not true. It only uses EF-series lenses. If you're upgrading to full-frame from a crop sensor camera, NONE of your EF-S series lenses will work with this camera. It's EF only. EF lenses will work on any EOS system camera, but EF-S lenses will only work on 1.6x crop cameras (Rebels, xxD series, and the 7D). They will not work on full frame or 1.3x crop cameras like the 5D series, or 1D/1Ds/1Dx series cameras.
As far as the light leak "issue". It's been addressed, for anyone reading this now... and was never really an issue for 99% of users. It only caused a slight metering error when the LCD is on during very long exposures such as astrophotography. It only affected a small number of units from the first batch of cameras, as well. None of the current models have this problem.

Did Canon repair the troubble between display and fotometer (light leak)?


Canon has  issued an advisory for customers to registor their cameras and check for updates. They will also inspect a camera for any customer who feels their camera is not working correctly.

Canon has announced the batches that have the problem. However, the fixing process is not clear yet. I have decided to return my camera and wait for a replacement.


I found this short video to be both informitive and easy to understand.  I for one will be upgrading from my present Canon 5D MK II, to the MK III. The new features are what I have been waiting for.

Thank you for a very informative video on The new Canon EOS 5D MK III.
