Canon Patent For Variable Diffusion Focusing Screen (Update: looks like focus peaking in OVF)

Canon Patent

Thanks Wade for confirming my first thought.

Edit: it looks as if the technology described in the patent provides a sort of focus peaking in the optical viewfinder. Cool.

Egami (translated) spotted a patent filed by Canon for a variable diffusion focusing screen.

The technology in the patent highlights sharp areas and helps to see how much depth of field you have (for instance at larger apertures).

Canon EF-S 10-18mm f/4.5-5.6 IS STM Review (Photography Blog)

Canon EF-S 10-18mm f/4.5-5.6 IS STM

The EF-S 10-18mm f/4.5-5.6 IS STM means one thing first and foremost: a lot of bang for the bucks. Here comes another review, by Photography Blog.

Excerpts from the conclusion:

The in-expensive Canon EF-S 10-18mm f/4.5-5.6 IS STM offers more features and much better image quality that you might expect given its price-point, making it a great ultra-wide-angle addition to a compact, lightweight EOS kit

[…] capable image stabilisation system makes it easier to hand-hold the camera and still get the shot. Auto-focusing is surprisingly quick, and for video shooters the STM motor is appealingly smooth and almost completely quiet, although not fast enough to keep up with fast-moving subjects in Live View/Video mode.

[…[ In summary we can somewhat surprisingly recommend the Canon EF-S 10-18mm f/4.5-5.6 IS STM as a lightweight, portable ultra-wide-angle zoom lens for APS-C DSLR owners that delivers pleasing results for both stills and video

Be sure to check the review, the samples, and all the test that have been done. The EF-S 10-18mm f/4.5-5.6 IS STM sells for $299. More EF-S 10-18mm f/4.5-5.6 IS STM coverage here.

Canon EOS 6D Sales Figures Not Satisfying?

Canon Rumors writes

We’re told that Canon hasn’t been fully satisfied with the sales of the Canon EOS 6D […] We’re told that the next iteration of the camera is likely to move upmarket in features and pricing.

Man, really? I thought a full-frame camera with a sensor having a better high ISO performance than the EOS 5D Mark III (see here too), plus built-in WiFi and GPS, and with a street price often below $1,500, should selling like hotcakes. Curious rumor. Maybe the many 6Ds I see around are faked ones.

Help Canon not getting bankrupt, buy one today! A very good EOS 6D deal by a reliable eBay seller can be found here.
