You can still see the size difference with the hood onHood's on though. Need to see it without the hood to judge the size, and then there's the weight.
I suppose the interest in f1.2 over the f1.4 will depend on the quality of the bokeh?
It's lighter than the Canon and nikon equivalents.The 85mm's not light at 905g, although I don't know how it compares to other lenses of this type.
