SLRgear Review December 5, 2011 by Andrew Alexander. In August 2010, Canon announced the next iteration in its super telephoto primes; the 300mm and 400mm ƒ/2.8 II lenses. The Canon EF-S 15-85mm f/3.5-5.6 IS USM Lens is sharp to the corners even with a wide open aperture. Corner performance is slightly weaker from 50-70mm with a wide open aperture, but still not bad. The EF-S 15-85 shows slight improvement in sharpness when stopped down to f/8, but really, little improvement is needed.

The image of the Canon 20mm f/2.8 USM gets larger as focused more closely. Color Rendition performance top. The color balance of this 20mm f/2.8 matches my other Canon EF lenses. Distortion performance top. This Canon 20/2.8 USM has the usual complex distortion seen in other 20mm ultrawide SLR lenses.

The Canon EF 16-35mm f/2.8L III USM ($2,199) is an upgrade to the EF 16-35mm f/2.8L II USM.It's more expensive—the II version was priced around $1,700—but sports superior optics for better

The falloff of the 16-35mm f/2.8 L improves at f/4, and remains the same at smaller apertures. It has has strong falloff at 16mm at f/2.8. The gray shots are of my Expodisc. This is a deviously tough test which shows even the slightest falloff. Except at 16mm at f/2.8, you'll almost never see this in normal photography. Lenses Compared Here. Let's compare the sharpness of all current Canon ultrawide lenses, which are the Canon 20mm f/2.8 USM introduced in 1992, the 17-40mm f/4 L of 2003, the 16-35mm f/2.8 L II of 2007 and the newest 16-35mm f/4 L IS, introduced in 2014. The biggest difference among ultrawide lenses is how sharp they are in the corners, so I'm Canon. RF 15-35mm F2.8L IS USM. 5.0. (2) Canon's fastest ultra-wide-angle zoom and part of a trinity of essential pro lenses, boasting a Nano USM motor, 5-stops of image stabilisation plus 3 Aspherical and 2 UD elements for stunning sharpness. Shop Now. 1. Wstęp. W lutym 2007 roku, wraz z premierą lustrzanki EOS 1D Mk III, firma Canon zaprezentowała obiektyw EF 16-35 mm f/2.8L II USM. Biorąc pod uwagę, że w tym czasie światło dzienne ujrzała także uszczelniona lampa EX 580 II, premiery te ucieszyły niezmiernie wszystkich fotoreporterów, którzy tym samym dostawali do ręki bardzo 比较明显得缺点主要有3个，第一，0.45M的对焦距离，相对16-35的0.28差距明显，哪怕变焦到35MM，这个对焦距离也够远的。. 第二，虽然这个镜头是 USM马达 ，但毕竟是快30年的对焦技术了，拍照对焦其实还可以，但是 视频对焦 ，会有犹豫，白天的时候可以接受 The distortion characteristic of the Canon EF 16-35mm f/2.8 USM L III is typical for a lens in this class. At 16mm you have to live with a rather strong barrel distortion (3.6%). This eases at 20mm (1.5%) and images are essentially free of distortions at 24mm. At 35mm there's a medium degree of pincushion distortion (1.7%). Measuring 3.3" x 4.1" (83.5 x 103mm) (DxL) and weighing 1.3lb (600g), the Canon EF 16-35mm f/2.8L USM Lens is relatively small and light . Build quality is very high - indicative of its Canon L Series heritage. This is a very nice handling and carrying lens. It is easy to take this lens with you - mounted or in a case.

De Canon EF 16-35mm f/2.8L II USM is de ultragroothoek zoomlens voor professionals met een spiegelreflexcamera met een volformaat sensor. Een constant diafragma van f/2.8 maakt dit objectief zeer geschikt om te werken bij weinig licht en om te spelen met scherptediepte. Toch wordt dit objectief niet alleen op volformaat camera’s gebruikt.
