The camera needs to know the focal length of the Lens to apply the correct magnitude of anti shake Compensate. You must have had a setting that matched (default?) that matched. If it didn't the anti shake would be even better if you followed instructions. joc

When I did my wee test to see if the anti-shake worked, I just put the camera onto the back of my A600/5.6 and went out and took pictures. I didn't know about inputting the focal length. I have not a clue about what the camera thought was mounted, but the antishake still worked marvelously. I don't know how big a deal inputting focal length will be in the big scheme of things, my guess is not very. For the record, here is the link again. Note, it is two exposures straight out of the camera, so the files are a bit big. http://users.accesscomm.ca/wrobb/temp/antishake/ William Robb -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
