What kind of lens is this

[meansizzler]

I have a sanyo xacti camera and it has a sort of lense which isnot as tall as a standard one and screws off

Is it a poor quality lens?

What does the lens filter do?

Does a 1.6x telephoto lens increase the zoom magnification by 1.6?, i.e 10 x appears to be 16 x zoom?

How does the lens affect video recording? i.e if I set the camera to record at 720P will the image look distorted when played back if using a wide angle lens

Where can you buy from in uk?

Hi there,

Full details of these types of lenses can be found on the Sanyo website. They are all good quality Sanyo lenses designed to fit and work with your current camcorder.

The Sanyo VCP-L06WU is simply a wide angle lens that converts the current lens into 0.6x magification. i.e 38 - 380mm into a 23-228mm lens (35mm equivalent).

Likewise the VCP-LO7WU also offer a wide angle conversion, though not as much, it offer 0.7 magnification so this would convert your lens into a 27-266mm lens.

Both will be good quality, although expect some barrel distortion and a slight drop off in sharpness particularly at the edges of the view.

The 49mm lens adaptor, I believe is a simple hollow adapter that allows a lens to fit compatible with 49mm size filter thread.

Does a 1.6x telephoto lens increase the zoom magnification by 1.6?, i.e 10 x appears to be 16 x zoom? Yes, correct.

How does the lens affect video recording? i.e if I set the camera to record at 720P will the image look distorted when played back if using a wide angle lens. The resolution you set doesn't matter, but expect some barrel distortion with a wide angle lens.

Hope this helps

I take it DSLR's don't suffer barrel distortion?

the lenses on D-SLRs can still have distortion although the amount depends on the lens you choose - for any lens, no matter what camera it sits on, generally you will find that the larger the zoom range the more distortion you can expect as it becomes harder to correct, but cost will play a role too - cheap lenses may have higher distortion than more expensive ones... but the reverse can be true as well! A prime lens (a lens with no zoom) will often have practially no distortion as it is much easier to correct.
