Premium Member Bill Totolo Posted November 5, 2007 Premium Member Share Posted November 5, 2007 Can anyone tell me why this lens doesn't require a focus ring? I'm sure it has something to do with being an "objective lens" but I can't find any info in the AC manual or by searching the forums. Thank you Link to comment Share on other sites More sharing options...

Thank you It's in what's called barrel mount or that is to say just the basic lens housing with an aperure control ring. A focusing mount could be added to this or it could be used that way on a set of bellows or whatever. It's f2.0 not f20 Link to comment Share on other sites More sharing options...

It's just an optical group that can have whatever focusing configuration and lens mount you want put on it. Link to comment Share on other sites More sharing options...
