Excerpt: 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.<br /><br />Not sure if my picture uploads will work so here are a couple links<br />http: //julianalee.com/homes/2014/hopkins_ave_1321/downstairs-living-room-a.jpg<br />http: //julianalee.com/homes/2014/hopkins_ave_1321/downstairs-living-room-b.jpg
Summary: I was instantly interested in this lens after Canon announced it - unfortunately for a shockingly high price. At this time I already owned a different third party 8 mm fisheye prime lens which suited me but which had some flare issues and only provided a semi-circular image on full frame camera sensors. Finally I found an excellent used mint lens copy of this 8-15/4 lens for a more reasonable price online.
Summary: If you have only full frame gear, you'll find the ability to do circular or rectalinear images wonderful, even with its limited true zoom range. And ALWAYS keep that hood in place or you WILL bump into things, at least until you get used to it. Great event lens, especially if you are willing to lie down and look up! Great landscape lens if you are willing to get get very close and really take advantage of its stopped down depth of field.
Excerpt: Since I've started using this lens about two weeks ago, I haven't switched it with my other L lens. I just love using it! It allows lots of creativity of a ultra wide angle lens. It's sharp at almost every f number.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Strong Construction
Summary: When I first got this lens, I thought the use was very limited. Now after 4 months owning this lens, I am loving it. I take it to all my trips and this is my standard lens 80% of the time when I am travelling. Great sharpness and the best thing is that I capture everything I see, I mean EVERYTHING!!
Conclusion: 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!!
Pros: Fast auto-focus, Superior build quality, Super-sharp images
