The first of the Pentax bayonet lenses were not given a letter designation, they are commonly refered to as "K" lenses after the mount type. (As opposed to M42 screw mount)If you have a good imagination the one long and two short flanges on the mount form the letter K if connected by lines. ;-/ The "M" series was next and was known for being lighter and smaller than their predecessors. Then came the "A" or "KA" lenses, these have the A setting and contacts to allow them to work in "Program" mode on cameras so equipped, such as the Super Program and on up to the ist D/DS. Then came the "KAF" and "KAF2" which added autofocus. These are given the "F", "FA" and "FAJ" letters. FAJ's have no aperture ring and aperture must be set on the camera. Now we have the "DA" lenses with a smaller image circle to match the the APS size sensor in the ist D and ist DS. They are KAF2 mount. The neat thing is all K mount lenses are "Backward Compatible". (Except for the DA and FAJ) And more letters to follow...(We all hope!) ;-) Don > -----Original Message----- > From: Jack Davis [mailto:[EMAIL PROTECTED] > Sent: Friday, November 26, 2004 8:29 PM > To: [EMAIL PROTECTED] > Subject: What series lens do I have? > > > Among those lens series' referenced on this list, is > one designated as "K".
