"Can anyone please help me (a newbie) understand the need of a wide angle and telephoto lense adapter, what kinds are avaiable, will I get more use out of wide as apposed to Telephoto e.t.c, and a good price range Australia or Singapore for my (model JVC GR-DVL510 10x Optical Hyper Zoom
500x Digital Hyper Zoom
Any Advice would be great

i love shooting with wide angle lenses... video and stills. you can get real close to things but still have a wide field of view so you get exaggerated perspective.

if you don't feel like you need one then i guess you don't. why do you ask?

Well I do not really know if I need one, If it does make the outcome more interesting then it would probbly be worth getting one. I recently went to the states for a holiday and it would have came in handy when filming the Grand Canyon.
Does vegas need to be configured different when capturing/rendering/recording back to tape at the moment I just choose PAL DV

the outcome CAN be more interesting depending on the imagination of the one who uses it. the Wide angle is definitely more fun than a Telephoto (to me anyway)

using a different lens will not affect the way you capture or record back to tape. where do people get such crazy ideas?

oh well... have fun.

Lenses come in different focal lengths and angles, or angle(s) of acceptance. Picture yourself standing in the corner of a room. If you have a lens with an angle of acceptance of 90 degrees or better, you can, in theory, capture all four walls and half of the ceiling and floor of the room in your shot. This perspective makes everything seem smaller, almost like looking through binoculars backwards, and gives the shot distance. Extremely wide lenses can produce distortion of edges and straight lines in your image as fisheye lenses do.

If your angle of acceptance is narrow(er)say 45 degrees or less, as in telephoto lenses, from the same corner, you would see less of the room in your shot, probably one wall or one corner, but this perspective will bring objects closer to you with more detail.

There are also trade offs when using inexpensive lens adapters. Since they are big pieces of glass, they need light, and if not precisely ground can distort your images.

FWIW

I love using a wide angle lens inorder to get indoor shots. It allows me to see the full room.

A telephoto is a MUST if you plan on using any zoom at all beyond the "optical zoom" capabilities of your camera. Your camera apparently has a "500x digital hyper zoom". My guess is that if you actually use that much digital zoom, it will look pretty crappy because it is a digital zoom, not an optical zoom. A digital zoom gets worse the farther in you zoom it. My camera has a 10x optical zoom, and then a 120x digital zoom. When I zoom between 10x and 120x, it is using digital interpolation to create the image, which becomes more noticable the farther you zoom. From normal to 10x it looks great, because it is an optical zoom (i.e. it is done with the lens). From 10x to about 20x, it looks ok, but if I take that image and then zoom in even more using VV3 pan/crop track motion, it suffers. From 20x out, forget it. Now, if I need more than the 10x optical my camera has, I just screw on a zoom lens, and it looks much better than the digital zoom did.

Go as you feel it, havana01. Go with your NEEDS, not with what others say you need...
YOU do the shooting, YOU decide what you need. Like other people said, a wide angle will help you for shooting inside tiny rooms, etc..
The perspective is also enhanced with wide angle lenses; and I think it is as important as the fact it covers a wide angle of what you see. Depth of field, that's what I'm talking about. Find something on the subject, you won't regret to go through this "theory"...
My recommandation would be: read books about photo, the lenses AND "cinematographic language"; from then, you will definetly see what you need for your shootings. A close shot of somebody's face is not the same as a medium shot; you "are with the guy" in one situation, you're "looking at him" in the other, for example...the examples are numerous and it's where the fun is when you shoot and edit.
And, like the other guy said earlier, don't rely on any "digital" zoom; it is crap.
What you'll record, you'll be stuck with it for the whole editing. You can correct to a certain extent but, like they say: "sh*t in = sh*t out...".
Most important: HAVE FUN !!!!!!!!!!!!!!!

A couple of points to add:

The advantages of a wide-angle lens are many.
* More of the image will be in focus at one time, i.e., solid depth of field, even with a wide aperture.
* More of the environment will be in the shot...thus the name wide angle.
* Wide-angle lenses typically gather more light, so you get less digital "grain."
* The wide-angle distortion can be used to your advantage in an artistic way, particularly if you have your camera at a severe tilt up or down.

The advantages of a telephoto, beyond the obvious increase of the reach of the camera, are not as obvious.

* When you do a long shot using telephoto, you lose the sense of perspective to some extent, "flattening" the image. When you have an interesting background behind your subject, it become difficult to tell how far behind the subject it is. You can get some WILD and nonintuitive effects this way.
* When you have an interesting background and an interesting foreground, you can "sandwich" the subject between them. The foreground object will usually end up blurred, so you can use it to frame the subject. Watch "X-Files" and you will see that the head and upper shoulder of someone in the foreground is often used to from the face of whoever is talking. This is almost certainly done with a moderately long telephoto shot.
* Be sure to use a solid tripod for telephoto shots. Drap or attach a camera bag or sandbag on the tripod to give it extra good stability.

As others have suggested, take a look at some photography books which outline these principles, and...play!

Thank you all for your help, and my appologies for posting a hardware question on a VV3 App forum.

A wide-angle lens is great for hand-holding a camera, since the shaking will not be apparent. You can even walk with the camera (carefully) and get usable video.

Wide-angles are especially useful indoors, where you can't back up to frame a wide shot. Outdoors, you need to avoid lens flare (bright reflections on the lens surface) and prevent auto-focusing on the dust particles that reside on the front surface of the lens (use a wide aperture setting, with an 8x neutral density filter to cut the bright sunlight; and use manual focus, if you have it). You may want to invest in a very good wide-angle, and a telephoto of lesser quality.

Good shooting!

Consider the depth of field factor. Wide angle lenses increase the depth of field while telephoto lenses reduce the depth of field.

Also, using high power telephoto lenses require a very sturdy/stable platform and a weighted or shock mounted camera tripod. Any minor bumps or vibrations are greatly increased using a long lens.
