49mm Uv Filter
- UV filters are individual compounds or mixtures to prevent ultraviolet (UV) light from coming through. UV filters are used in sunscreens to protect skin or in photography to reduce haziness or fogginess created by ultraviolet light.
- This is an Ultra Violet absorbing filter that helps overcome the abundance of blue in outdoor photographs. Not really necessary in digital photography as the camera's white balance system adjusts for the colour temperature of the scene.
- This coating is a filter for the harmful UV radiation. The coating is either put on the lens or is imbedded into the lens to protect your eyes for the harmful effect of the sun’s UV radiation.

ISO6400 test shot
Taken to demonstrate K20D high ISO capability
taken as RAW and PP done on the PC in an effort to maximize image quality
Lens is SMC Pentax-M 35/2.0 f=5.6
This photo was posted as part of a discussion about certain compact cameras alleged ultra-high-ISO capabilities.
Please note that this picture was taken with a rather good APS-C sensor (23.5X15.6mm compared to 5.3X4 to 7.6X5.7mm used in compacts) and an old but very sharp prime lens. Also note that most compacts does not record RAW files and in-camera processing is usually inferior to that done on the PC.
