Zeiss has teamed up with Fellowes Brands to announce an intriguing new product line at CES. The duo utilizes Fellowes Brands pedigree of smartphone photography technology and Zeiss’ wealth of lens manufacturing history to bring an iPhone lens trio. Pictured is the existing Exolens accessory mount by Fellowes Brands. It provides a solid platform to mount an additional iPhone lens, as well as a 1.4″ thread on the bottom for further mounting. Zeiss have provided the optics to make up 3 new lenses for the iPhone 6; a wide, tele, and macro zoom lens. “The first three lenses – wide-angle, telephoto and macro – are scheduled to be launched in late Q2 2016. The wide-angle and telephoto lenses offer excellent image performance with outstanding edge-to-edge contrast. The macro lens features a zoom function – unique for accessory lenses of this type – for flexible image composition. The new lenses can be used on the Apple® iPhone® with customized mounting brackets.” All lenses utilize Zeiss’ trademark T* coating for anti-reflection. It also “minimizes reflections at the glass-to-air surfaces and improves the transmission of light.” The Zeiss Mutar Exo-Lens Wide is a 0.6x lens adaptor that will increase your iPhone field of view by 40%. The Zeiss Mutar Exo-Lens Tele is a 2.0x lens adaptor that will double your iPhone field of view. The Zeiss Vario-Proxar Exo-Lens Macro is interesting: “It is currently also the only accessory lens for mobile phones to offer a continuous zoom function, permitting the full-frame capture of objects with diameters of between three and twelve centimeters. An optionally attachable and semi-transparent diffuser serves as a spacer, allowing light to shine evenly on the object to be photographed and enabling convenient focusing, even with a short object distance and shallow depth of field.” The iPhone lens trio for the 6/6 Plus will look to ship Q2 this year. Here are some images Zeiss released taken with the set of iPhone lens, check here for more.Read more

Samyang has broadened its line up with release of a new lens. The Samyang 135mm f/2.0 is manual focus only and currently stands as the longest available none reflex mirror by the many-name brand. The full name of the lens is the Samyang 135mm f/2.0 ED UMC, ED stating use of a low dispersion lens and UMC an acronym of Ultra Multi Coating, which is applied to some of the 11 lenses in 7 groups construction. The Samyang 135mm has a typical specification for a fixed focal length prime, with perhaps a few upgrades when comparing to the Canon 135mm f/2.0 L. The aperture diaphragm is constructed of 9 rounded blades versus Canons 8, it has a larger 77mm front diameter, but 90g heavier at 830g. The most notable difference between the Samyang 135mm and Canon counterpart is perhaps the minimum focus distance, at 0.8m and 0.91 respectively. Samyang lenses are known to be affordable, and the 135mm f/2.0 is no exception, at $549 it currently sits nearly half the price of the Canon 135mm f/2.0 L. This is largely down to auto focus; as with all Samyang lenses the 135mm f/2.0 is manual focus only. The lens will be available in a whole host of mounts, Canon EF, Nikon AE, Pentax K, Sony A & E, Samsung NX, Fuji X, Micro 4/3s and even Canon M. If, like all standard Samyang lenses, expect the aperture ring to be clicked with a likely future cine version with de-clicked aperture and permanently geared focus ring. I’d also expect this lens to pop under other many-brand banners, including Rokinon and Bower. A 135mm prime can often become overlooked, it’s not one you’d find in the average filmmaker/photographers kit bag. This is mainly down to the fact that the popular 70-200 covers this focal range, and the staple macro lens competes closely with a 100mm fixed focal length. The 135mm prime has its uses however, it offers an extra stop at f/2.0 compared to f/2.8 that you’d find on a 70-200mm zoom or 100mm macro; that makes a huge difference. That’s not to mention the amount of light you lose through a zoom or macro; a t-stop rating of these versus a 135mm would surprise many I’m sure.Read more
