    Default Fisheye Lens

    Looking for a 30mm fisheye lens for 30ish.

    Wondering if this would fit my camera?

    FishEye 0.42x Wide Angle Video Camera Lens 37mm 27 30.5 on eBay, also, For Digital SLR, Camera Lenses, Photography (end time 30-Nov-08 19:36:30 GMT)

    If not could somebody post one.

    If it has the right thread size / adaptor I am sure it will be good.

    Dont forget with that lens you will get lots of barrel distortion and you may not be able to use all of the zoom.

    I've been through a few of these things, trying to find one that works well. Just be prepared for a few compromises that may occur:

    It will give barrel distortion by definition.
    It will suffer from Chromatic abberations on the edges.
    It will have sharpness failures on the edges.
    It will vignette, possibly only the corners on 4:3, but entire sides on 16:9
    You will have to run your camera on 'wide', anything above a very short zoom will go to pieces, pointless zooming through W/A converters anyway in most cases.
    Your camera's metering may be confused by it, as the vignetting loses lots of the image, ensure you camera has centre weighted metering, which most do as default tbh.
    It may show up lens misalignment issues, most domestic video cameras are not aligned very well with the CCD chip, so your vignetted image may appear slightly off to one side, which won't become apparent unitl editing.

    Knowing the limits lenses like that can be fun, and may not actually be an issue for what you're filming, might even add to it for all I know, so for 28 quid give it a go.

    I have a .35x wide el cheepo for my film and run camera - I hardly ever take it off as the very wide distorted look goes great with the way I use the camera.

    Yeah I've got this little collection, plus a few others:



    They can be fun as I said, and often for a few seconds in a movie the quality issues are not important. We must remember that film making should be fun!

    Hehe.

    Nah, think back to my intro post here. I'm a fiddler. I like to fiddle with things.

    Once I'm over the video equipment event horizon I'll go and buy some decent stuff :-]. Besides, there isn't enough ink in my keboard for a list.

    Sorry but I don't really want to have to play around, I'd rather like a fisheye that would be fine =/

    But if I get a 30mm it'll be ok?

    If your camera has a 30.5 mm thread then yes, it'll be 'ok', but don't kid yourself that it's going to be as good in clarity as the camera's own lens.

    In addition the lens is actually a 37mm, but uses a supplied step down ring to knock it down to 30.5. With a step down ring the lens is positioned further away from the camerra, and so vignetting is worsened somewhat.

    You keep saying 30mm, check it's 30.5.
