Just aquired a 150mm Sironar-N MC. Are the shift limits identical to the current model? Read some contradictory comments on this topic.

According to the list published on Kerry's website (http://www.thalmann.com/largeformat/agevs.htm) the lens was manufactured between 1980 and 1984.

Martin, Perhaps take the specifications from Armin, and perform some field tests? Remember, you can peek through the open corners of groundglass to visually check for vignetting. Do this free test before you use valuable film. Looks like great coverage for 4x5! PS: I checked: looks like 40.59mm vertical, 35.63 horizontal - data courtesy of my friend Mike Davis. A very useful lens IMHO.

Those specification are at infinity at f22.

Thx for your comments. The values provided by Armin are identical to the ones of the current Apo-Sironar-N.

As the lens is multicoated I assume that the overall performance is not that bad too.
