Chris wants to bust the myth of the camera bag accessories and the sun filter. Chris says that sun filters will usually limit the visual spectrum and doesn't really do much for the image other than cut out ultraviolet and infrared light. Those were very valuable and improved your pictures when shooting with film. But when you shoot digital, it just doesn't apply, since IR and UV filters are already built into your camera. So it's counterproductive to buy them.
The glass filter will also distort the image and some of the light will get reflected away. So don't bother with the filters. The filter may protect your lens elements from breaking, but you really need to get a good one that also has a protective coating. The other myth is the camera bag, which Chris says is usually too small to be of any good.
