It s vastly improved image quality and superb contrast make it a worthy upgrade if you have the extra cash to upgrade or are buying a 16 35mm for the first time. This canon ef 20 35mm f 2 8 l was canon s first professional wide angle zoom. It was announced at the 27th of august 2015 and is available since october same year.
The 50mm focal length when used with a 35mm film or full frame sensor has.
Canon ef 16 35mm f 2 8 l ii usm lens. The ef 50mm lenses are a group of normal prime lenses made by canon that share the same focal length these lenses are based on the classic double gauss lens with the f 1 8 being a standard six element double gauss with an air gap and powers between element 2 and 3 and its faster cousins adding additional elements. The canon ef 16 35mm f 2 8l iii series lens is the successor to the ef 16 35mm f 2 8l ii series lens. It has been specifically designed for improved edge to edge image quality that will meet the strict requirements of professional and high end amateur photographers. The ef 35mm f 1 4l ii usm is a successor of the ef 35mm f 1 4l usm.
The canon ef 24 70mm f 2 8l ii usm lens is the sharper lens of this group even at f 2 8 vs. Featuring a series of specialized elements this lens utilizes a trio of aspherical elements and two ultra low dispersion glass elements to control a variety of aberrations for high sharpness and clarity. The ii series has soft corners and exhibits way too much vignetting imho at 16mm. Covering a useful wide angle focal length range the ef 16 35mm f 4l is usm is a canon l series lens distinguished by its constant f 4 maximum aperture sophisticated optical design and use of image stabilization to realize sharp imagery.
These two lenses perform more similarly at f 5 6 and at f 8 where their results are nearly comparable. It has been specifically designed for improved edge to edge image quality that will meet the strict requirements of professional and high end amateur photographers. Note that the canon ef 24 70mm f 4l is usm lens exhibits some focus shift. Two ultra low dispersion elements are used to greatly reduce color fringing and chromatic aberrations throughout the zoom range for high clarity and color.
Canon was trying to take the professional market away from nikon with their new eos. The ef 16 35mm f 2 8l ii usm is a high performance water resistant and ultra wide angle canon l series lens. The 16 35 f 2 8l iii is similar to the zeiss 15mm f 2 8 classic lens and the canon ef 24mm f 1 4l ii usm lens at f 1 4 in this regard but among the strongest vignetting lenses available. Again the results are similar at f 11.
The canon ef 20 35mm f 2 8 l is optically as good as today s newest canon 16 35mm f 2 8l ii and canon 17 40mm f 4l but smaller better made and much less expensive to buy used. If the all wavelengths of light in the visible spectrum refracted identically a lens designer s job would be a lot easier.
