Canon Shows Off the Inner Workings of Its Lenses in Cool CES Demos

Unfortunately, what with major changes at the helm and making sure that we hit 2014 running, we weren’t able to make it to Vegas for CES this year. And I say unfortunately because, not only does it mean we’ll have to wait a minute to get hands on with some of the new releases, but it also meant missing cool demonstrations like the ones you see above.

The video was filmed by Stan Horaczek over at Popular Photography and it shows the demos that Canon is currently running on the showroom floor to tempt CES attendees over to its booth. Read more…

But I’m always careful not to stop down too far because I was taught, soon after I picked up a camera, that if you stopped down too far the dreaded diffraction softening would kick in.
