My Sigma is the older 170-500 (not so sharp at the long end) & I have found that f9.5 is needed for acceptable sharpness. I started with the Jack Davis formula: TAv, 1/2000, f8 but soon changed to f9.5. The K7 is ISO challenged being noisy above ISO 800 but, from the K5 onwards, even ISO 6400 should be OK. With the K7 in poor light I drop the shutter speed & hope for the best. As Paul says, exposure compensation in camera or post-processing amounts to the same thing. I agree that photographing distant subjects (which they mostly seem to be!) is counterproductive but still useful for identification.
Yeah, those eagle photos are more souvenirs than anything else. -- Larry Colen [email protected] (postbox on min4est) http://red4est.com/lrc -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
