I finally got my hands on a 12-60mm. I found a killer deal on craiglist I couldn't resist. It was almost half of retail and in mint condition with a UV filter included. It doesn't look as though it has ever been used. I ordered a Cokin ring to fit it so I can use my ND grad. So far I really like the extra focal length at both ends. As far as focus. Yes it is fast. Faster than my 14-54mm? If so I can't tell it is by much. It certainly performs better in low light. The weather here has been cold, rainy and gloomy so I haven't gotten out with it yet. As soon as that weather clears I hope to get out some. If you haven't looked on craigslist you should. I have seen some really sweet deals on some gear.
