I believe the DA should work as an "A" lens in A position and SuperProgram should be able to control it. At least my SuperA does (but only with genuine Pentax lenses, I had no luck with Sigma). You can choose Tv mode on the camera and control the aperture value indirectly by forcing the shutter value.Jarda Houdekhttp://www.pentaxfriends.eunoreply@blogger.comtag:blogger.com,1999:blog-34648316.post-48149020606437497342009-09-23T03:04:38.724-07:002009-09-23T03:04:38.724-07:00Thanks for the comment. I would not know until I shot a roll of film in trying out. It seems the lens may meter wide open as others have told me. In the viewfinder, I don't see the obvious vignetting as seen in putting a Pentax DA 18-55mm f/3.5-5.6 on a film body such as Pentax P-Z1 when I tried it before without film loaded.Hin Manhttp://www.blogger.com/profile/11542007867767875530noreply@blogger.comtag:blogger.com,1999:blog-34648316.post-20297092819644955692009-09-22T12:00:59.204-07:002009-09-22T12:00:59.204-07:00I love mine SuperProgram, but I'm using it with smc-M 20mm f4 lens. Too bad that A vesion of 20mm was only made with f2.8. What is the frame coverage of the DA21?Anonymousnoreply@blogger.com
