guide trusted dealers Carl Zeiss Milvus 2/35 ZF.2 Nikon lens review: Affordable quality


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). read more

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.

Canon TS-E 24mm 1:3.5 L II review

PMA 2009 was a show distinctly light on noteworthy announcements, but one of the most technically interesting developments may well have slipped under the radar of many enthusiast photographers. Canon introduced two new perspective control lenses to its TS-E (‘Tilt and Shift for EOS’) range, in the shape of the TS-E 24mm F3.5 L II and the TS-E 17mm F4L. But while the latter quite naturally grabbed the limelight as the widest-angle perspective control optic ever made for an SLR system, both feature a significant improvement over existing mainstream designs. read more
