Huss -- great shot!
You cannot go wrong with trying out the Canon 50/1.4 -- it is cheap enough that you can buy, try, and re-sell if you don't like it. The minimum focusing is drawback if you like 0.7m, as well as its often-highly-dampened focusing (but probably many of these 50s need a good re-lubing). I find that the 50/1.4 is a high-performing lens that probably was as good as it got in the early 1960s at that speed. At f/2, it is stunning -- as the photo aboves shows.
