But that, of course, will reduce the resolution to only 5MP ... :-) Note that the A20 has this mysterious feature called 'blur reduction', which cuts the resolution down by a factor of two. From the very limited description in the press release this doesn't appear to be all that different from the current Fuji super sensor; for each site there will be two pixel values recorded - one for the shadows, and one for the highlights. Pentax are spinning it differently, with the emphasis on being able to use a high iso (to avoid blur) while not burning out the highlights. It's also a little different in implementation - the Pentax sensor appears to be dynamically re- configurable, while the Fuji sensor has dedicated sensor sites for each purpose (of two different sizes). I'm not convinced this will help that much with avoiding the nasty quantisation effects that you get in the shadows on digital images; while a digital sensor at ISO 1600 is better than equivalent film in the brighter parts of an image, it's still pretty unpleasant in the shadows. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
