OK one last question and i hope you can bear with me.
For both 40D or 5D, in which order would you buy the following lens supposing it's not in your arsenal yet :-
1)EF 35mm f/1.4 L USM
2)EF 50mm f/1.2 L USM
3)EF 85mm f/1.2 L II USM
4)EF 135mm f/2.0 L USM
Bearing in mind the various criteria from the thread so far... i.e Portrait, indoors and outdoors, bokeh ( must be heaps better than the f/4L lenses ) etc etc.
Thanks in advance!
The bokeh for 85/1.2 and 135/2 are great (which I can comment on because I got both of them) but they probably more suited for FF. I would buy 135 first for FF since it is the cheapest in this range.
