I have both.... As far as IQ...... I think the 70-200 MKII is better than the 135L. As sharp or sharper, better color and contreast in the few direct comparisons I have done (I am not doing anymore). Zooms have arrived. With that said, it can't do f2 and the 135 is much lighter and smaller. This makes the zoom far more usefull in some circumstances, in others, the 135. For me, they are not redundant.
"Zooms have arrived" mine arrives tomorrow!!!!
Thanks Bohdank! I saw your comparison post and helped me decide to get the zoom.
