Re: Sky, UV, Haze filters?
Although I used a polarizer quite frequently at one time, I now feel that it causes oversaturation and blocky looking colors in many cases. I'll use one for landscapes when the sky is pale or when haze and/or reflections are a problem. But that's about it. I do use yellow and red filters for B/W landscape photography, but I don't do much of that these days. I'm more into portraiture and people pics at the moment.

I photograph near the ocean frequently, so I want to keep the inevitable fog off my lens. I know, intellectually, I understand they can, but I suppose I just never thought of it. I have been testing a new camera and am not yet satified with the prints I'm getting. I've been [silently] blaming the processor. Maybe I should take another roll or two with that filter OFF! Good heads up. Thanks. keith whaley

In other situations, it just adds another piece of glass reducing the efficiency of the lens and contributing to flare. Most filters are not multi coated, and even those that are generally are not up to the standards of pentax SMC lenses. The best filter for most situations is no filter. Paul
Re: Sky, UV, Haze filters?
What about the 81A and 82A filters? I and can't remember when. or what I last used them for. I have a feeling it had something to do with Daylight/Tungsten film or like that! Is there a Filter FAQ on the Web?

Does a polarizing filter eliminate the use of the three? > UV filter is essentially a lens cap. They don't do anything that the glass in the lens already does. Sky and Haze are generally the same thing, and essentially subtract about 50ºK from the colour of the light being transmitted. The idea is that daylight is often too blue, so warming things up a bit is a good thing. You can get stronger filters, such as UVB and UVC that give a stronger effect. I tend to distrust the little buggers, as more glass is bad glass to my way of thinking, but I do have UV-C filters for my longer telephoto lenses, on the off chance that they actually do something useful. Polarizers are a different animal altogether. However, stacking filters is aways a gamble. William Robb This message is from the Pentax-Discuss Mail List.
