Does the job well
2010-01-27Just what I needed. Protects my Canon EF 50mm 1.8 II lens. No noticeable change in image quality. Gives protection and piece of mind. Well built. Cheap.

Cheap Protection for your Lens
2009-12-28This is a cheap way to protect a relatively expensive investment - your lens. Buy this and keep it on all the time, that way if you scratch this, you don't damage the lens. On non L lenses it has the added benefit of helping to keep dust out of the lens.

Works well
2009-10-15I bought this primarily to protect the glass on my lense. I have not done a comparison of shooting in the same situation with and without it.
I can happily say that it does a great job of protecting my lense, has a quality feel to it and does not distort my pictures.
I would buy again!

Good, but not the best quality
2009-04-18The filter was good for the price, but don't expect it to be perfect. The glass is a little loose. Other from that, it's fine.

Avoid this seller
2009-01-16Not only did this seller wait two weeks to ship my item (Ordered Dec 31st, shipped January 12, 2009) they sent me a used and stained filter. I had to clean the heck out of it for it to even look OK. Never again. Seller ignored all e-mails.

Why You Should Use A Mini DV Camcorder
Introduction
The mini DV camcorder has many advantages to offer its users. If you enjoy your digital video camera you will also enjoy this. The mini DV camcorder is easier to take with you than the regular sized cameras such as the hi definition camcorder, or the hi-Res camcorder. The size of this camcorder is one of its big advantages. The features this camcorder can offer are also great. Some cameras offer more features than others, so make sure that the camera has the features you want.

Generally when design, performance and technological improvements are made on electronic products there is a reduction in size as well to make them more compact.
For example the early day radios were built in large cabinets and required radio vacuum tubes. Eventually, transistor radios were constructed and were more portable. Today, a radio can be as small as a wristwatch.

Camera basics: shutter-speed, aperture and ISO
In this article, I’ll introduce you to the basic elements that you can use to control exposure in your shooting. If you have a digital SLR, there will be a way to set all of these controls on your camera, but since they differ between manufacturers and models, you’ll need to refer to your camera’s manual to find out exactly how to change them.
All cameras, whether an ancient film camera, or a more modern digital, work in pretty much the same way. Photographs are taken by letting light fall onto a light-sensitive medium, which records the image. Traditionally, this has been film, but more recently, it tends to be a digital sensor. The more light that falls onto the film or sensor, the lighter the image.
Put simply, a camera consists of a light-tight box that stores a light-sensitive device (either a film or a digital sensor), a lens that magnifies and focuses the image onto that light-sensitive device through a hole in the box (called the aperture) , and a shutter that opens ...
