Thanks for the replies so far, and please keep 'em coming. My test unit has a string of blobs near the center (most people seem to report them "near the center" for what it's worth). They are noticeable at f/8 and smaller when photographing a blank surface; I suspect in real photographs (with plenty of detail) they should *maybe* be noticeable at f/11 and onwards. I rarely photograph at such apertures, but I can imagine people shooting landscapes would be annoyed to find these blobs in their blue skies. Then again, a blob in a blue sky is easy to clone out. Then again, again, we'd all prefer not to have to clone out blobs as part of our postprocessing. —M. \/\/o/\/\ --> http://WorldOfMiserere.com http://EnticingTheLight.com A Quest for Photographic Enlightenment -- 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.
