    Re: Power Focus Mode (500mm & 600mm f/4L II USM)



    Thanks Jan! I guess I wasn't too far off. But I'm wondering know why they introduced it first in the long range lenses. Like HDNitehawk said, it's expensive enough as it is [*-)]


    I feel there might be a bigger market for shorter lenses with videographers, but then again maybe they're trying to wedge into Sports videography...?

    Sports, races, wildlife, maybe even video the family 100 yards away with a 500mm or if your a peeping tom you can transition from one window to the next with your 500mm fairly smoothly (that was a joke, not advice for peeping toms) ..but its going to need to be fairly quick on the long lenses. Just being smooth is worthless if its to slow.

    Sheesh, Canon is being such an enabler [:P]


    I'd imagine it'd be fairly quick, considering 500mm would cover such vast distance. I'm thinking the slower of the 2 speed settings is more for smaller changes in distance (maybe matter of couple meters).


    Hopefully the improvements in image quality of the lens will justify this addition. Otherwise I'd imagine lots and lots of angry people []

    I got the free lens book when I joined CPS and it has a chapter that has all the charts and tells you how to read them.


    If you go to Canon's website and look at the 500mm chart. If the IQ for the new 500mm is like the charts promise, the new 500mm will be the sharpest highest IQ in Canons L lineup. The 600mm will not be far behind.


    From what the charts show. The lens may be very usable with the 2x at 1000mm.
