Photographers use diffusion filters to create a softened effect in an image. There is a wide range of filters available, each creating a different degree of diffusion to a shot. One of the best ways to learn when to use a diffusion filter, and how to use one, is to practice with all different types of filters in different environments.
For full-frame shooters, a fixed f/2.8 aperture, 70-200mm zoom is an extremely popular lens for shooting sports, wildlife, reportage, events, weddings as well as portraits, making it a versatile and must-have lens for many pros. The Sony lens promises outstanding resolution, as well as attractive bokeh thanks to its eleven-bladed circular aperture.
The fast f/2 maximum aperture makes it a versatile prime lens for low-light photography. The 35mm focal length facilitates a field of view akin to human vision (excluding peripheral vision), which makes it a nice focal length for capturing scenes with natural perspective; and it’s a popular choice for photographers shooting events, weddings, or environmental portraiture, as well as interiors and architectural photography (if you can get far enough back).
Announced in September 2015, the $1117 Carl Zeiss Milvus 2/35mm ZF.2 Nikon (Milvus 35mm f/2) is an FX-mount Nikon lens designed specifically for full-frame Nikon DSLRs such as the D800E. The fast f/2 maximum aperture makes it a versatile prime lens for much low-light photography. The 35mm focal length facilitates a field of view akin to human vision (excluding peripheral vision), which makes it a nice focal length for capturing scenes with natural perspectives, and it’s a popular choice for photographers shooting events such as weddings or for environmental portraiture, as well as for interior and architectural photography (if you can get back far enough).
The lens features the large f/4 maximum aperture desirable for achieving fast shutter speeds; Sigma’s 4-stop image stabilizer (OS) for shake-free images of relatively static subjects, using shutter speeds as slow as 1/30 of a second; and Sigma’s hypersonic autofocus motor (HSM) for responsive AF performance.
Combined with its wide f/1.2 maximum aperture, the focal length makes it a very versatile all-round prime for low-light photography, portraiture, general use, and creative out-of-focus background bokeh effects. Optical construction utilizes 19 lens elements in 14 groups, including 1 super ED (extra-low dispersion), 2 ED, 3 HR (high refractive), 1E-HR (extra-high refractive), and 1 aspherical, and all with Z-Nano Coating to help reduce flare and ghosting. The lens’s internal focusing system guards against protruding elements during focusing, and autofocus is driven by Olympus’s MSC high-speed autofocus motor.
For our DxOMark lens reviews, we evaluate the performance of interchangeable lenses for cameras equipped with sensors that can capture images in RAW format. In this article, we explain how we test for different criteria in the DxOMark image quality test lab and how the test results translate into sub-scores and the final DxOMark lens score.
