Super Wide-angle for CP5700

    I bought the Nikon Fisheye converter lens for my CP5700 and was not really
    overjoyed with the results, mostly because Nikon didn't provide sufficient
    info on its use. After playing around with the thing I've discovered that it
    makes a moderately good super wide-angle lens. If you have one of the things
    try this:

    Select Wide-angle converter from the Lens menu
    Select Macro with the focus button (side of lens mount)
    Zoom all the way in (maximum telephoto)

    Note that if the camera is set for Wide-angle converter it will not zoom
    past a certain point. At this point the original circular image will just
    fill the full image frame as a rectangle. My measurements show this to be
    equivalent to a 17mm lens on a 35mm camera.

    For an even wider view zoom back out to where the macro icon (the yellow
    flower) turns white. Then bump the zoom button the other way until the
    flower just turns yellow again. At this point the circular image will be
    slightly flat on top and bottom. Take these images to Photoshop and create
    and center a 1600 x 1200 pixel fixed size marquee on the image. Then do an
    Image > Crop. If desired, use incremental Image > Image Size (about 10% at a
    time) to get the image back up to 2560 x 1920 pixels. You will lose almost
    no sharpness and will end up with an image equivalent to a 14mm lens.

    I've almost forgiven Nikon for making such a lousey lens.

  2. What were you expecting when you bought the lens? A full frame fisheye
    or a circle one? Why do you consider it lousy? Not sharp? Poor
    resolution? What? If it wasn't what you expected, why didn't you just
    return it for a refund or a credit on another lens?

    Having no previous experience with fisheye lenses I had no idea how sharp
    one would be compared to a conventional lens. Based on the limited user
    "manual" supplied with the lens the sharpness was poor. After some
    conversations with Nikon I learned the correct way to use the lens. Even
    then it was not really sharp, but not so bad I felt like returning it.

    I was well aware that the lens produced a circular image, and use it in that
    mode. The point of my post is that it also serves as a fairly good wide
    angle. In fact, used full frame as I described gives the sharpest images.

    Overall, I don't feel like this lens is typical of Nikon quality.

    It's not just the lens, it's the combination. Coming from a 990/FC-E8, the
    5700/FC-E9 combination is a huge disappointment. Not sharp isn't the issue.
    The full frame image can only be used at the full wide circular position.
    Anything else and the outer quarter of the image is out of focus, not just
    not sharp. Makes the lens a curiosity, not a tool.

    Would you say the FC-E8 on the CP5000 would give better results than the
    FC-E9 on the CP5700 ??

    Thanks !

  6. Have your tried manually setting your f-stop to less than wide open to
    see if that improves the quality of the fisheye images?

    My past experience with any accessory fisheye lens (for film or digital)
    is the quality of the images are poor at best. Basically, it's a toy.
    I have one I bought about 30 years ago, that I've used as a paper
    weight for the past 29.5 years, and it's not good at that: It falls
    over too easily. ;-)

    I can't say from experience. The problem with the FC-E9 would appear to be
    caused due to it's being smaller than the camera lens objective size where
    they couple. The UR-E10 adapter need necks down from the camera to the neck
    of the E9. I don't know offhand if an adapter is required for the 5000/E8
    config. The 990 and E8 required no adapter.

    Overall as a "package" I find the 5700/TC-15/WC-80/FC-9 combination
    substantially lacking compared to my old 990/TC-3/WC-63/FC-8 combo. I don't
    know what the heck the lens designers where thinking with the newer combo.
