"This is absolutely a first rate lens that is second to none when it comes to quality! I have not taken it off the camera since I got it. I have wanted this lens since Sony announced it over two years ago. Unlike most anything else, I've waited, primarily due to the price. I actually thought about picking up the 28-75 2.8 when it came out, but after looking at one in a store, decided I just didn't want to comprimise on this one. I finally took the plunge and am kicking myself for waiting so long."
