Mark, from your last posting on this thread: I have a 135 WF Ektar f:6.3 too. From what I can measure, it takes something close to a 54mm filter (?). Is the Series 7 to 52mm adapter you mention in your posting a screw-on or push-on?
I'm a little confused by anything 'Series-to-XXmm' that is screw-on. Isn't 'Series 7' actually a range of diameters?
I also have the same filter adapter issue with a 210mm Ektar f:6.3. It seems like that lens takes something more like a 42mm filter (?) which I guess is a Series 6.
thanks for any advice...
