  1. A partially transparent mirror seems a lot like the old 1960’s Canon Pellix SLR.

    The light sensitivity was reduced somewhat, and the viewfinder was not as bright as wanted, and it went away quickly. I am always on the lookout for one of these for my collection, but there were few produced, and they are uncommon.

    It seems awfully complex.

  2. Photographer/Videographer on

    It’s clear that Canon is developing a faster AF system for LiveView (they already stated that months ago at Photokina) as well as improving Movie mode, because they know that those features will have Huge future and demand

    LiveView has enormous potential.

    Sometimes is impossible to use the viewfinder, or just much easier to use LiveView.

    Also the information displayed in LiveView can be a lot more than in the Viewfinder.

    Each way to frame and shoot has its own advantages, so they both MUST be available considering the customers have a very wide range of different needs / tasks / jobs

    Thinking that a feature “should not” be included in a DSLR just because “it does not belong to the DSLR world” or one doesn’t use it, it’s a mistake due to having somewhat narrow perspective of other people’s needs, the trends of technology, the demand and the companies’ business.

    This improvement indeed will help a lot the Movie/Video mode in DSLRs, wich is also going to be improved and implemented in future DSLRs, despite some people like it or not.

    (if you don’t like, just don’t use the feature. It’s that simple. And if you don’t want to pay “more”, don’t worry, it won’t make much difference to today’s DSLRs, so the “extra” price won’t show up)

    LOT OF CUSTOMERS, both Amateurs and Professionals (Photographers and Videographers) can get lot of advantages of such implementations, wich will offer a level of quality and features that are not still available under several thousands dollars (and some are even inexistant yet)

    So, GREAT NEWS that Canon is working on it. Hope that Nikon and other companies do the same.

    The more competition, the faster and better systems development.

  3. There are enormous creative possibilites with live-view, but only with an articulating LCD. I’d give up the viewfinder if I could just have a 2.5″ or 2.7″ articulating LCD. When I first got my Nikon 5400 (mail order as nobody in Alaska carried it at the time), I was overwhelmed by the creative power I now had. I could compose and shoot from right at ground level all the way to 12 feet off the ground when I used my monopod. With a standard viewfinder on my XSI, I’m limited to a 2 foot space with my old back and hip where I can reasonably bend down to look through the viewfinder. My “Fix” has been to use an ultrawide (the 10-22 USM) and just point the camera, then fix the composition with cropping. Thank god for megapixels.

    Hey, CANON… don’t let Sony beat you on this one, GIVE ME AN ARTICULATING LCD!!!!!

  4. I like it when Canon innovates. Hopefully, we’ll see more. But I think live view AF needs to go hand in hand with a good OLED screen (to improve visibility in daylight).
