I'm fine with a 50 the size of the new 35/1.8.

My only requirement is that it has to be sharp as h#ll.


Sharp as h#ll, and no extreme vignetting please. Oh, and perfect round bokeh circles across the frame at f/2.0 or f/2.2 please without pronounced outer lining. I bit like the Samyang 85mm f/1.2 XP would be nice. Oh, and no fringing of course. 3 stops of IS is enough. Canon can skip the other 5 if that will make a smaller design possible. And i don't need a macro feature at 50mm too, so if skipping that too to make it more compact it's fine by me.

I think it should actually be a little bit bigger than the 35mm. Not too big of course, but it should be big enough to meet the other requirements, you know.....

+1 Keep vignetting to a minimum since I’ll be using this as a general purpose lens and not just for portraits, plus this’ll help to keep the bokeh balls round!  

But reducing the fringing (c/a) with the inevitable aspherics is surely going to give us some onion ring bokeh, esp at this level of lens.

IS would be nice, but I’d get by with IBIS (R5).  However IS will be welcome for use on the lower tier bodies (at least for the time being).

Lastly, 1:2 macro would be very handy at this F/L (for me).
