This is, without any stretch, the best glass in its class, the brightest star in the entire line of lenses for Sony. And yes, perhaps the best portrait lens on the market. I had experience with the Canon 135 2/0L and I can say that it surpasses it in the most important thing - in the final perception of the picture, and surpasses it convincingly. But it is inferior to "Elka" in practicality for professional use and in autofocus speed. The difference in their price, I think, is justified. A must have lens for all Sony portrait photographers. And in itself one of the most convincing arguments for the transition to this system.
