Excerpt: If you are looking for a sharp ultra wife angle lens for specialty shots, then look no further. This is a great lens whether you are shooting in tight spaces, want to show a large vista, or get a little creative with the fish eye. Highly recommended!
Excerpt: I have no gripes about the lens, itself, as I enjoy using it. My only complaint is about the lens cap. It is extremely poorly designed and it will fall off when least expected. How Canon has not been able to come up with a better design is beyond me.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight
Cons: Lens Cap Easily Falls Off, Poorly Designed Lens Cap
Excerpt: As has been mentioned many time before, the flimsy lens cap is the only negative of this fine lens. I would have given it a 5 star rating but considering that the front element protrudes in front of the lens barrel, having a good lens cap is essential, in order to protect it from scratchs which because of the extreme depth of field of this lens would be apparent in any photograph taken with this product.
Pros: Consistent Output, Easily Interchangeable, Exceptional Angle Of View, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: I use this lens mostly for landscapes and de-fish them in CS6, which works excellent and provides wonderful wide angle landscape scenes full of vibrant colors.The lens is light and focuses quickly.My only complain is the loose fitting lens cover. For a lens that has so much exposed glass, Canon did a poor job of securly protecting the glass (also, this is why I only gave the product 4 stars, as the glass needs much better protection from the lens cap slipping off way too...
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
Excerpt: I've had it for about two weeks and I've found doing anything below 14mm (which is when you start getting the black rounded corners) to be awkward. Maybe I'm not as creative as I hoped. Perhaps a fixed 15mm fisheye is all I need. I'm still not sure. Except for the flaky lens cap, I have nothing technically bad to say about the lens. My problem lies with my own capabilities with a fisheye.
Summary: I'm using this on a crop sensor, so I don't get the round center picture with black borders effect. I only get four black corners at the widest focal distance which is undesirable. That's where the limiter switch comes in handy; it stops me from turning the zoom ring below 10mm past which point heavy vignetting will start to occur. So far I found this lens very sharp and fast, and bokeh is nice and soft at f/4. This lens, like all fisheye lenses, is a novelty lens.
Excerpt: I got this as part of the Google Trusted Photographer program (360x180 panoramas). It was either this or the Sigma 8mm Fisheye. These are already such limited-use lenses, so I just went for the one with more features. Take note: the lens cap attaches only to the lens hood. Some say it's a loose connection, but it seems fine to me.
Pros: Comes With Lens Pouch, Fun, Google Tip Certified, Google Trusted Photograph, Gtp, Sealed, Solid Construction
