How to increase zoom power for sony dcr sr82?

I just bought the sony dcr sr82……this is my first time owning a camcorder so I dont have anything to compare and contrast it to…but just going by what I have here, I was wondering if this is as good as it gets?

the camcorder has a zoom setting where I can set it up to 2000x…so I took the camcorder outside for a test..I started to zoom in ..and well it does do some zooming but at about 3/4 of the way in things started getting extremely blurry…

and I thought, is this the way its supposed to be? What would be the purpose of allowing the camcorder to zoom that much in while the whole thing becomes so blurry? So I was just wondering if theres something else I could do to make it better? I set the focus all the way up to infinity so..at maximum, zooming in still gets blurry at 3/4 of the way…

There is “optical” zoom and there is “digital” zoom. Optical zoom is the lens actually zooming. Digital zoom is the camera taking a guess at what the picture would look like if you could zoom further. I don’t know why they even bother to put digital zoom on cameras – it almost universally looks horrible and blurry like you describe. The more you digitially zoom, the more guesswork it has to do, the worse it looks.

What you can do to increase your zoom is to buy and add on lens. Typically these lenses are like 52mm, so you may need to buy an adaptor (for my Sony MVC-CD500 I had to get a 46mm to 52mm adaptor). Unfortunately these don’t zoom a lot, like 2X (maybe the ones they make today are better), but 2X is better than nothing. You can also buy wide angle lenses (less zoom, mine is 0.48X), ‘fish eye’ lenses, etc.

My advice would be to stick to optical zoom. You might even want to (if you can) disable digital zoom altogether, so that you don’t accidentially select it.

What are the Side Effects Associated With Zoom Teeth Whitening?

Whiter teeth in a short period of time: this is the promise of zoom teeth whitening. Though there are plenty of teeth bleaching agents available for home use as part of kits sold in the supermarkets, teeth whitening under the close supervision of a professional is often the wisest and most effective solution of all. What is zoom teeth whitening? We are talking about a medical procedure that uses laser technology to lighten the mild or serious discoloration of the dentin and enamel. On an evaluation scale for testing zoom teeth whitening, parameters indicate an eight-shade whiter enamel after undergoing the procedure.

The zoom teeth whitening procedure should not be longer than an hour; yet, previously to the intervention as such, the dentist will inform you whether there are other steps to be taken or not before the bleaching as such. For instance, professional cleaning of the dental structure is required before the use of the zoom teeth whitening technique; this usually takes around a quarter of an hour, while the rest of the procedure, the bleaching as such last for around 45 minutes on the whole. Before using the zoom teeth whitening system, it is good to get some info on the way things go during the intervention.

Before the laser light is applied to the teeth, they’ll be treated with a hydrogen peroxide gel that is broken under the light impact allowing oxygen to enter the enamel. The structure of the tooth remains untouched during the zoom teeth whitening, as the gel only acts on the discolored dentin portions. In terms of comfort, patients usually don’t feel a thing while undergoing the zoom teeth whitening process, and they are encouraged to focus on other things like a TV or some music in order to make time pass more pleasantly, till the bleaching procedure is over.

In terms of side effects associated with the zoom teeth whitening, mild tingling and sensitivity to the treatment may appear, since the laser light generates a small amount of heat. Such minor discomforts could be prevented if you use anti-sensitivity toothpaste prior to the treatment. Once you’ve seen the great advantages of zoom teeth whitening you’ll definitely worry about how to maintain the brightness of your smile. Using a fluoride paste, flossing and brushing the teeth at least twice a day are the first precaution measures to be taken; these are actually the same that ensure a good health condition in the mouth.
