  • deciphering lens codes

    Posted by Bob Woodhead on May 6, 2007 at 1:33 pm

    How DO you interpret the codes on lenses? Thinking of buying a HPX500, and trying to determine which lens to go with. Obviously I could buy the most expensive package & call it a day, but I’d rather be slightly more informed than that. eg; Canon KJ16x7.7B-IRSD HDgc versus Fujinon XA17X7.6BRM-M58B
    Or is this cloaked in the veil of “crew-only” knowledge, like C47’s?
    PS – I’ve looked at the specs, but that’s lilke reading a racing sheet to see which horse is going to win – they ALL “read good”.

    Fujinon and Canon both list their codes on their websites.

    Try this: https://www.usa.canon.com/opd/view/QPFSearch.jsp

    click on “accessories” on the left

    Now, click on “Lens Model Number” on the top right.

    Let me know if this doesn’t work.

    just in case – a Canon KJ16x7.7B-IRSD HDgc is a Hi Def 16 power lens with a 7.7mm starting focal length, it has a built in extender, motorized zoom, manual focus, motorized iris, and a digital drive. It belongs to their new “gc” series.

    Thanks Steve…. should have found that myself I suppose. I just found it hard to believe that a 2x extender is a $4000 difference between the KJ16x7.7B-KRSD HDgc & KJ16x7.7B-IRSD HDgc. But then I looked at the $39,000 models & decided to be happy Canon’s got this new line of “affordable” HD lenses…

    It’s not real easy to find the info sheets. I have told them about it.

    They get it because they can, not because of anything to do with costs, just like Sony.
