I can't afford the Sigma 85 f1.4, it's a little out of my range. I'm sitting in the $500.00 dollar range for a lens. So, I need to stay within my means, as I only spend the money I make from photo shoots on camera stuff, keeps me in line. The Sigma 30 F1.4 is out of the question, as I do plan to upgrade to FF by the end of the year and I don't want to invest in APS-C lenses. I already have the 15-85 which I'll sell with the 60D when the time comes.
So, it seems that both lenses are good choices but maybe the 50 is a little better from what I'm reading. I guess I can mount the 70-200 F4L IS is I need the 85mm range.
Thanks for all the feedback! Unless I see any other reason to not get the 50 or if you think their is something that might work better than either of the 2 lenses I mentioned, I'll order the 50mm 1.4 next week.
