Night and day. 1 is a push pull zoom, 2 is not. 1 is fairly large, 2 is fairly compact. 1 is a really good lens, 2 is a fantastic lens. They are also different shade of off white. The only things they really have in common are, made by Canon and focal length. I sold my original version so I could buy the new one.
Also, the II ver. has, as part of it's design parameters, the ability to work extremely well with the ver.III extender.
