With lens detection ON, the menu then pops up an option for manually selecting which focal length you are using. It defaults to 24 mm if you do not make a selection. This is good because you can code a Zeiss 18mm as a WATE and it records 24mm and processes the Raw file just fine. Very handy if you cannot justify paying for the WATE (now over 10,000 here!) The camera cannot detect which focal length you have manually selected in this specific case. You do require the frame-lines actuation as well as the coding. Even though you cannot use the internal finder with the WATE. Actually it activates the 28/90 lines but you can't use them for framing. The frame line actuation is an AND operation with the 6 bit code. I have not handled the earlier Tri-Elmar. I believe that it had a much more complex mechanism and does select the correct internal frame line (28-35-50). 2009/1/23 Frank Filippone <red735i@earthlink.net> > I believe that because of the Tri Elmar, and later WATE, the VF is used to > determine FL to some degree.
