The main reason why you will stop down this lens, is not for getting a higher resolution, but to play with the background blur and the depth of field. The sharpness of the Canon 35mm f/2 lens is high all the way from f/2 to f/11. In the field test of this lens on a Canon 650D, we sometimes achieved a gain of 4 stops, when we compared the sharpness of the images visually. Our test results show that with IS, a hand held shot image at a shutter speed of 1/6 second is, thanks to the image stabilization, as sharp as an image shot without IS and a shutter speed of 1/50 second. The optical IS offers a 4-stop advantage according to Canon. The Canon 35mm IS lens offers instead intelligent panning: the panning IS mode automatically switches on, when needed. There is no switch for panning (horizontal IS only). The Canon 35mm 2 IS lens has two switches: AF/MF and IS on/off. If you already have a Canon lens and often use the lens hood, there’s good news: The new lens caps are also available separately. This allows the lens cap to be replaced while using a lens hood. This lens cap has a grip in the middle, instead of at the side. New Canon lens capįrom January 2013, all Canon EF lenses come with a redesigned Mark II lens cap. Because this lens has a USM motor, you can at any time overrule the AF and use the focus ring to focus manually, without first having the switch the AF off. But what about apertures larger than f/11?. You can see that at aperture 22 anything between 2 meters and infinity is in focus. There is also a depth of field scale engraved onto the lens, but it is of limited use. The lens has a window where you can read the distance where the lens is in focus. Still it is one and a half times as heavy as the Canon f/2 version from 1990, which does not feature built-in IS. The lens body is made of high quality plastic, which limits the weight to 300 grams. The Canon 35mm f/2 IS lens is very well built.
Even though the image was shot well after midnight, with a shutter speed of 1/4 second and without the use of a tripod. The built-in image stabilization is effective: The above image is still sharp, thanks to the image stabilization and the excellent signal/noise ratio of the Canon 6D at 6400 ISO.
