  1. Mark, if you search through the site you'll probably find more info here than you can digest in a day or two. i'm sure you'll

    get the answers you want from the collected wisdom here in photo,net.

  2. Wing Shing Camera Co in Mongkok, Kowloon gives you the best deal in town. The salesmen

    there don't speak English that well though. Anyway, this lens is so popular that it frequently

    runs out of stock. You may get it elsewhere (eg the camera stores in Tsimshatsui) if you're

    willing to pay a premium.

  3. "I'm curious for what applications the 10mpix vs 6mpix difference will make a real

    difference? It must make a difference, because the digital SLR companies are locked in a

    megapixel race it seems."

     

    As far as I understand, pixel count, expressed as megapixels, is just the multiplication

    product of the number of horizontal and the vertical pixels. Your RD-1 has a 6.1

    megapixel APS C-size CCD sensor with 3,008 (horizontal) x 2,000 pixels (vertical), and

    should be able to give you decent 16ᄀᄄ x 20ᄀᄄ prints.

     

    In fact, a 10MP camera only have 40% more linear resolution than that of a 5MP camera.

    And this kind of difference is almost invisible to most, if not all, people. For any visible

    improvement in resolution, you need at least a doubling of linear resolution. This means

    you need to quadruple your megapixels to get any visible results.

     

    I believe the ᄀᆬmegapixel warᄀᆭ is pretty much a marketing war that could quickly replace the

    ᄀᆬmegahertz warᄀᆭ. I just bought my Casio EX-Z850 (8.1MB) the day EX-Z1000 (10MB) was

    released, with a bargain of course.

     

    So, to answer your question Frederick, the difference between a 6MB and a 10MB, when

    you blow up to 16" x 20", should be minimal, if at all visible.
