Nope. Aliasing is possible whenever the (spatial) frequency of the image is higher than that of the sensor. The interesting thing is that with 24 megapixels in an APS-C sensor you probably won't need an anti-aliasing filter in all but the most extreme cases (the absolute highest quality glass (at its optimum aperture), tripod mounting, mirror lock-up, high shutter speed). The Nikon D800 is notorious for demanding only top-shelf lenses and the pixel density of a 24MP APS-C sensor is even higher. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
