The others cited, to my inderstanding did and do not differentiate between stated (as marked) and actual (as tested) focal length of each individual lens vs. lens model. More than several lens companies have produces a lens (and maked it as such) in the 50 to 55mm range. Hopefully this clears up what I was stating. Brian Levy, J.D. Toronto, Ont. dlevy@worldy.com
