The Canon EF 50mm f/1.4
Here you have some of the work of this morning with the lens that my Italian friends has lent to me. It's a very good lens with very good building quality, and also a very good "bokeh". The only bad thing of the lens is that is not very sharp in 1.4, but really works good in 2 an 2.2. Other ways the chromatic aberration can be saw clear in the corners but is not anything that can be fixed with Lightroom.
Enjoy!
