Just about the time for both lenses especially the 50mm 1.2 that on most bodies gives an equivalent of 80mm just the right one for portraits etc.
I wish they could come out with an IS version of Bigma 50-500mm in L series.
Also the price of f/4 70-200mm, if correct as stated, is a bit high IMO as it would make more sense to be close or just under the f/2.8 non IS cousin.
What I am just wondering for not only Canon, but Nikon and VR lenses, is what would their response be toward the very smart approach of Sony in keeping IS / VR inside the body, therefore making any lens IS capable, as put on the new married Sony-body, Minolta-Lens digital SLR, "Alpha A-100 DSLR"
