I bought this lens to enable me to acquire some more creative shots. It ended up being so much more than that. The colors are exceptional, and all of my photos have been clear and crisp with minimal flare. I have used this lens for architectural photos, macros, and outdoors photos. I especially like how with outdoors photos it captures your entire field of view, giving you a shot no other lens can produce. An excellent buy despite it weighing as much as the camera body.

I love this lens. It never disappoints me. The focus is fantastic and the colors are great. A lot of people ask me with an element of curiosity what I use a fisheye lens for (as if it has limited uses) but I think the lens is especially useful for architectural arches, large ceilings and art images. I took this lens backpacking with me through the middle east and found that it consistently produced images that portrayed the enormity of the mosques and palaces I visited, unlike my standard lenses which could never capture the whole room in one frame. This lens has radically changed my photography for the better.

Cons: It's a little heavy.
