I use this lens both on a crop camera the Canon 60D and the full frame at a Canon 6D. On full frame rich without sunshade 3-4 images for a spherical panorama which accelerates the workflow tremendously. The image quality is very good for this price. But should be dimmed to a minimum aperture of 8 for right-sharp images. I use this lens mainly to a photobooth for celebrations and weddings. That means I make once the aperture and change them all evening ideally not once. For Part photos with great depth of field of this lens is ideal. I set the focus to 0.8m and at f 8 all the action in front of Booth is sharp. Due to the fisheye effect, this is in this Anwenungsfall definitely more fun lens but this is certainly desired. The manual iris adjustment does not bother me personally. At the Photo Booth I even point and finished the aperture and focus distance. Even with other applications, such as panoramas, the setting is quick and not troublesome. At the Canon lens displays a panel of F00. Who but with the manual adjustment has no problems should also quickly cope with this lens. Who does not have a full-frame camera and do not want to so quickly jump on one is well advised with the version I of Walimex with the rigid sun visor.
