We are happy with the lens. The description was accurate and it works just fine. If are looking to buy a lens, canon doesn't dissapoint.

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

great lens, just got it today and haven't put it down for a second. I am still wondering how to shoot in the circular fisheye mode that is shown in the second sample image section, would really like to know--why i bought the lens!!

Fast auto-focus; Superior build quality; Super-sharp images

Here's (another) update after having used this lens for almost 2 1/2 years. This is one lens I always try to take with me just in case an opportunity presents itself. I have examples of this lens on a FF here:http://www.pbase.com/pegsam/fisheyeShooting at 8 mm is pretty straightforward and it does...

More versatile than I originally imagined

Lovely lens with lots of creative uses

Very sharp

Hood design

Consistent Output; Durable

The other day, I went out on a photo shoot to exercise my new Canon EF 8-15mm f/4L Fisheye USM lens. This lens produces circular 180o fisheye images with full-frame cameras at 8mm, and diagonal 180o fisheye images at 15mm.

Купила внепланово, хотя интересовалась давно: курс евро рос, мои небольшие рублевые сбережения таяли на глазах. Вот и купила. Пробовала на всем подряд: на интерьерах квартиры, на виде из окон. Очень нравилось всё, что получалось. Отличная цветопередача, красивый рисунок.

It's a very nice product

Everything

Nothing

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
