I am actually shopping for a lense for myvideo camera. I bought the Panasonic PV-GS400 3CCD dv digital video camera. I want a wide angle lense for it. I have been looking at the Canon 7151A002 WD-43 (43mm threads on my camera).

Anyway, it says it is .7x. I'm not sue exactly how wide of an angle that is, as compared to smaller or bigger numbers. I'd really like to see some images showing the difference if anyone knows where to find them (or just explain it to me)

Other than that, maybe someone would have a suggestion for a better wide angle lense than the Canon.

Thanks a lot

For wide angle, the lower the number the better.

I don't know your video camera, but let's take a 35mm lensas anexample.

A 35mm lens with the .7 wide angle converter attached would be 35 x .7 = 24.5mm. Which is seven tenths of the original lens.

With the .5 converter, it would be 35 x .5 = 17.5mm. Five tenths, or a half of the original lens.

Sorry, can't help with the rest of it.

Thanks... so the smaller the number, the more 'fish eye' effect it would have?

You would likely suffer from some barrel distortion but not quite the fish eye effect.

Many wide angle lenses display this phenomenon without the addition of a converter lens, which usually makes it worse.

But this can easily be corrected in most editing applications.

Though i'm not completely sure about video, I would imagine tools would be available to correct this effect if it really bothered you. You might be able to happily live with it yourself.

If possible, try an attachment on your camcorder before you buy.
