Re: wide angle adapter lens
The wide angle aspect of video lenses seems to have been overlooked (perhaps disregarded) by the camera makers.
Most rave on about how many times optical and digital ZOOM they have, forgetting entirely that the wide angle end is just as valuable.
A trip through the speccies of most new cameras reveal the widest setting to be around 40 degrees - the same as the unaided eye.
For those familiar with 35mm stills terminology, about a 50mm equivalent.
Yet there are soooooooo many things that can be done with a decent (or half decent) wide angle.
It would be fantastic if they could give us (in 35mm terms) something like a 28 to 200 which was a standard purchase, or as Canon did ten years ago, a 35 to 300mm zoom.
Until then, I guess we will just have to shop around for wide angle converters.
I use a Sony (made by Carl Zeiss) one for my Sony DV handicam. It cost about $120 and is worth its weight in gold. I use this more than the "normal" lens, and get some stunning results. The mount thread is 39mm, and gives me a 28mm equivalent.
When I was growing up with 35mm, I bought some fisheye converters, and they really were cheap and nasty.. proving that you gets what you pays for.
The only caveat with a W/A converter is to be very careful of stray light and dust on the lens, as the depth of field will go from the lens surface to infinity in sunlight, and any dirt will 'flare'.
Have a check of the various ads in the mag and manufacturer websites for the converters. Oh and treat them like they are made of eggshell, as the multi coating on the lenses is very delicate.

I have a DMC-FZ100, DMW-LA5 adapter and an Olympus B-300 HQ 1.7x Tele Converter (instead of a DMW-LT55 - but that's another story). I also bought a DMW-LW55, thinking that I could fit it to DMW-LA5. However, looking at the LA5 Instructions, it says "(As of July 2010)The following types of lenses cannot be attached and used. Vignetting etc. may occur when taking pictures in wide)- Wide conversion lens DMW-LW55- ND filter DMW-LND55- MC protector DMW-LMC55" This is very annoying considering that the LA5 is sold as THE adaptor for DMC-FZ100, DMC-FZ45, DMC-FZ40. So what's the solution? A 52mm to 55mm step up filter ring? Will the wide angle lens be too close? Then there's the Panasonic DMW-LA2(E) It looks shorter than the LA5, but will there still be a vignetting problem? I am still seeking answers.
In this case you'll find that having the wide-angle converter further from the lens will affect the angle of view a little, but the main effect will be vignetting. All you can do is try it and experiment with different aperture settings to minimise the effect. In any case, you'd be better off in every respect by mounting the DMW-LW55 directly to the adapter, and then mounting the adapter onto the filter. To do otherwise will lead to dreadful colour fringing as the adapter and wide angle converter lenses are optically matched and designed to be a particular distance apart.
Most add on lenses are designed to be used at a certain focal length, a zoom should be used (is most effective) when you are completely zoomed out, (really why would you add a zoom lens then not zoom all the way) a wide angle lens should be used with the zoom all the way in (cause your getting the widest angles). As far as quality, you really shouldn't have an issue except you may get black edges depending on how big the end of your lens is. Good luck
There are lenses available to add with an adapter ring. I have the wide angle lens (which I LOVE) and a 2x telephoto lens. The wide angle lens allows me to macro from several feet away. It is an amazing lens. The telephoto lens is something you really need to use with a tripod. But yes, there are lenses you can add to your camera.
The DVC7 has a 43mm filter thread on its lens. Depending on your Bower's thread size, you may need a step-up or step-down adapter ring to fit it to the DVC.
After checking if you have your sizes correct, you need to remove the DVC7's lens hood. After that, it's just a matter of screwing the wide angle lens to the DVC's lens.
Hope this helps!
These screw on the front of the plastic lens adapter and adjust the focal length. On the side of the adapter lenses it will quote the ratio. My wide angle says 0.66x so just multiply the range of focal lengths by this figure and you will see that it adjusts the camera zoom accordingly - making the image wider and probably also increasing the depth of field (what is in focus). Similarly a 1.5 tele will inrease the range of focal lengths to make the lens "longer" eg higher magnification , useful for astro photography - shots of the moon and terrestrial long distance work but detracting from the depth of field, eg the range of distance over which objects are in focus will be reduced.
The wide angle will allow you to come in close and get WIDE objects fully in-frame- hence "wide angle", while the telephoto will give you better overall maginification of the image but will probably increase the MINIMUM focal length - eg you may not be able to focus on objects closer than >2m (instead of ~1).
The screw-on adapter lenses I found were cheap in a Jessops sale use a 52mm thread, while the S5500 provides a 55mm internal thread. I use an appropriate 55mm to 52mm step down ring adapter. There is slight vignetting (shading around the edge of an image) at certain combinations of zoom, but generally these are very useful accessories.
As these are adapter lenses on the front of an already powerful 10x zoom that must be optically compromised at the price of this camera, there maybe some colour fringeing around bright images. If you want a better solution you really need to get a DSLR. Overall a good solution for the price.
That's completely normal for those cheap wide angle add on lenses. There good for a little fun but nothing serious. I bought the lens kit for the Kodak DC3400, probably the exact same lens.
The telephoto in that kit was actually pretty reasonable though.
If you want to add other lenses, either macro, wide angle, telephoto or just filters, they go directly on the adapter. That's why the thread size (62mm) is important because that's the best fit for that adapter. If you get other sizes you can still use them with step rings but that adds to the expense and stepping down can cause vignetting.
