Canon 50 1.4 / Sigma 50mm 1.4 / Canon 50mm 1.2L comparison

Previously I posted a thread on my frustations with the 50 1.2L. Now that I sold it to buy a 85 and 35L I am missing that lens a lot. I wish I had the budget for that lens again.

Sean Reid has published a review comparing the 50 1.4 by Sigma, the 50 1.4 and the 50 1.2L by Canon. I find his review in line with my experiences wih the 50 1.2L. Based on his review and after my time, a month now, with the 35L and 85L I would really like my 50L back. Using the other Canon primes I see more clearly how to judge the 50L. Before I only had the 135L.

For Sean Reid you have to register on his site and pay a small amount to be able to read his reviews. I did so a while ago and have enjoyed reading his reviews a lot.
