Re: Color codes on lenses?
Some of the wide angle lenses have a setting to where if you line up the color coded f stop with the same color coded distance mark, you get the assurance that everything from (something like) 3 feet or so to infinity will be in focus. I think it was a feature to allow manual focus lenses to be "left alone" and the photographer would be reasonable assured most of his photos would be in focus.

Re: Color codes on lenses?
AFAIK, that is Pentax's method of showing you which F-stop is the minimum recommended for a hyperfocal setting. Other manufacturers do that too (My Olympus XA has a similar color difference at f8).

Is this the marking for the best apperature, in Pentax's mind, for the given lens? Do the colored markings vary with different lenses, or are all the f8's this color? Stupid question I know, just curious...
Color codes on lenses?
I have recently acquired a few SMC primes and noticed that the f8 setting is colored in orange. Also, there is a similiar color of orange marked on one of the distance settings. Is this some kind of hyper-focal setting? Is this the marking for the best apperature, in Pentax's mind, for the given lens? Do the colored markings vary with different lenses, or are all the f8's this color? Stupid question I know, just curious... __ Do you Yahoo!? Yahoo!
