About the famous Yellow Dot. Some Aero Ektars you see have a mysterious and apparently cult-inducing Yellow Dot on the lens shade. The origin and meaning of the Yellow Dot has been much discussed on several websites and in forums, but as far as I know the real meaning of the dot, if any, is not known. I have had three Aero Ektar lenses in here, with and without dots, and I can say that as far as I can tell, there is not any difference between dotted and not, none at all, except at least a hundred dollar premium on ebay for those lucky enough to be marked that way. Keep in mind that thousands of these lenses were produced and are very common, and although the auction prices have risen to the $300 level recently, good examples can be bought for less, if you shop around.
If you get an Aero Ektar, I recommend you visit this site for an excellent mount and shade. I have both!
The Aero Ektar is the poor sister in a sense to the much more expensive and luxurious Schneider Xenotar 150mm f2.8 lens, which can be fitted, at even greater cost, to a Compur No. 2 or Copal No. 3 shutter, for those unfortunates who are stuck with mere Linhofs. I have that lens on our primary test camera, here.
The Xenotar is cool, but not a very great lens unless you need f2.8, and they are way too expensive on ebay. The Aero Ektar and its war surplus connotation is appealing, and the extra inch of focal length and f2.5 aperture make it very good for those who want selective focus.
