Canon’s 50mm f/1.8 II – The Nifty-Fifty
Canon may announce a new 50mm f/1.8 STM lens very soon, according to Canon Rumors:
We’re told production of the Canon EF 50mm f/1.8 STM has commenced and we can expect an announcement in late March or early April with availability coming soon after.
I rate the rumour CW3.
The “Nine Key Attributes of Reputation” used by FORTUNE Magazine for their ranking
Canon’s press release of yesterday, when they told us the company is among Fortune Magazine’s most admired companies of 2015 turned out to be based on some misunderstanding of the involved figures.
DIY Photography posted a lengthy article where they point out why the “prestigious accolade” Canon put in the title of the press release isn’t so prestigious after all. First and foremost, Canon got it wrong with the nine key attributes Fortune used to rank companies (and so did I for that matter). Canon writes:
Canon received its highest ranks in innovation, social responsibility and long-term investment value.
Well, it’s exactly the opposite. The nine key attributes are listed in the picture on top. A higher number means a lower ranking. Canon didn’t receive the highest ranks for innovation, social responsibility and long-term investment value, but for Quality of products/services, Financial soundness, and Global competitiveness. Oops.
There are more critical issues in DIY Photography’s post. For instance they stress that
[…] the “World’s Most Admired Companies” list is actually the “World’s Most Admired Companies By Other Companies” list. Client satisfaction or feedback from the general public was not calculated into the scores
While I do not agree with all of the reasoning in the original post (it is still a good thing that Canon tops for the quality of their products), I recommend you have a look at DIY Photography to get the entire story.
Chief Executive Fujio Mitarai said his company had the funds and willingness for more acquisitions this year after a planned 23.6 billion Swedish crown ($2.8 billion) takeover of network video surveillance leader Axis AB (AXIS.ST).
Mitarai has been leading efforts to find higher-growth businesses to complement Canon’s imaging expertise, and help the Japanese company expand beyond a camera market under attack from smartphones sporting competitive image-capturing capabilities.
Canon’s offer for Axis represented a premium of nearly 50 percent to the stock price before the announcement, a price some analysts said was high enough to ward off rival bids.
“If you buy a cheap company, you need to spend on drastic restructuring,” Mitarai told Reuters in an interview on Tuesday. “I only buy good companies, even if they’re expensive.”

I and others on the web have been told that Canon may announce a new 35mm “L” lens later this year, possibly before Fall 2015. While we do not have any specs or other information, I was told that some prototypes are already out in the wild undergoing testing. I strongly suppose this will be a f/1.4 lens, also because we had some patents filed by Canon pointing in this direction (1 | 2).
