...is LOOONG, but I WILL make it work! I got the 135L a few weeks ago, my first L lens. Finally had a chance to use it for portrait work today (went apple picking with the family, convinced my kids to pose for me for a while). HOLY SMOKES, the 135L is a portrait monster! Tack sharp, super rich colors, and the most creamy bokeh. Wow. After 15 minutes I understood why the 135 has the reputation it does.
I am already used to making the 85 1.8 work on my 50D for outdoor portraits b/c I am such a fan of it. And I know from past experience that even the 85 can be too long for much indoor portrait work. But for now, I am going to just get used to standing a half a block away from people because I will make the 135 work!
Thanks to all those who offer opinions and samples on here...they definitely guided my purchase and I could not be happier with my first L lens purchase!
