The new Canon EF 8-15mm f/4L Fisheye USM is a world-wide popular accessory. Leveraging on its unique focal length range, the EF 8-15mm f/4L USM, it has become the world's widest fisheye zoom lens.

Dual circular and diagonal fisheye options on full-frame cameras; Impressive image quality; Fabulous L-series build quality and ring-type USM autofocus

Absence of circular/diagonal versatility on APS-C and APS-H cameras; Fisheye distortion effect is minimized at 15mm on an APS-C camera; Quite expensive for a fisheye lens

There are plenty of inexpensive fish-eye lenses out there, including the Lensbaby Circular Fisheye and the Samyang 12mm F2.8 ED AS NC Fish-eye . But there aren't a lot of zoom designs (Pentax and Tokina both sell a 10-17mm fish-eye for APS-C SLRs), and none other that switch from a fully circular...

Unique, zooming fish-eye design; Full circular image at wide angle; Full-frame compatibility; L-series construction

Hood must be removed for full circular effect; Expensive

There are plenty of inexpensive fish-eye lenses out there, including the Lensbaby Circular Fisheye ($361.66 at Amazon) and the Samyang 12mm F2.8 ED AS NC Fish-eye ($349.00 at Amazon) . But there aren't a lot of zoom designs (Pentax and Tokina both sell a 10-17mm fish-eye for APS-C SLRs), and none other that switch from a fully circular field of view to a more traditional fish-eye look as the Canon EF 8-15mm f/4L Fisheye USM ($1,249) can. It also includes autofocus, compatibility with full-frame cameras, and the build quality and weather-sealing that you expect from an L-series lens. The cost may be a turnoff for photographers in the market for what is an occasional-use, special effect lens, but there's no arguing with the quality of the product. DesignThe 8-15mm f/4L Fisheye USM ($1,249.00 at Amazon)  is sized similarly to other ultra-wide zooms. It measures 3.7 by 3.1 inches (HD) and weighs in at 1.2 pounds. The front element is bulbous, and there's no thread to accommodate lens...

The Canon EF 8-15mm f/4L Fisheye USM is a unique lens that can capture a circular image or zoom-in for a more traditional fish-eye look, but you'll pay a lot for it.

Unique, zooming fish-eye design; Full circular image at wide angle; Full-frame compatibility; L-series construction

Hood must be removed for full circular effect; Expensive

The fisheye camera lens was originally developed so that the whole sky could be captured in one single image to help meteorologists study cloud formations. However, the extravagant 180-degree angle of view soon found favour with photographers.

Handling and features Performance Verdict Specification This unique lens offers two lenses in one for full frame camera users. At 8mm it provides a circular fisheye image, with a 180 degree field of view in all directions.

Excellent sharpness; in the centre of the image area; Superb build; Unique zoom design effectively gives full-frame users two lenses in one; Useful for owners of multiple Canon camera formats

Expensive; No way to lock the lens at either end of the focal range; High CA levels towards edges of the picture area

Although cheaper, lighter lenses are now designed purely for these smaller sensors, professional lenses are still designed for full-frame use. It is rare, however, that both formats are considered, as it is difficult to satisfy both from one lens without overly inflating the cost or sacrificing the...

Pros: Strong Construction, Creative, Fast / accurate auto-focus, Durable Cons: Other thoughts: Great image quality, good for architecture and city photography.

I wanted to find an ultra-wide lens for taking pictures of small rooms. The 14mm is awesome but sometimes not wide enough. Setting this 8-15mm at about 12mm then clicking the de-fish button in Photoshop gives ultra-wide.Not sure if my picture uploads will work so here are a couple linkshttp:...
