Thanks Robert,
that was what I was thinking....since my camera body was one of the first ones out, it is my understanding that the 135 was the first lens designed and there was some problems with that lens, so the 100 was issued...I have never seen a 135. I obtained the 100 and it works fine on my older body, I was under the impression than the camera would not focus correctly with this lens, but it does, so maybe if i get the 135 it will also focus but i will need to adjust my composition in relation the frame? In any case through the view finder you do see all and more of the image....
have you used the 135? It is the only lens for the camera that I do not have...myabe that is what is bugging me!
thanks
