Coming early next year, Voigtlander will be giving some new ultra wide-angle lens options to Sony mirrorless photographers. Today they announced plans to release a 10mm f/5.6, 12mm f/5.6, and a 15mm f/4.5 as native Sony E-mount designs in spring 2016.
With the slower apertures and extremely wide focal lengths, these lenses are surely meant to appease architectural and landscape shooters who desire to pack as much of the environment into one frame as possible. The Voigtlander 12mm f/5.6 and 15mm f/4.5 lenses are already available on the market with a Leica M-mount, and previously an adapter would have been required to get it attached to the Sony lineup of mirrorless cameras. It’s not clear yet whether these new E-mount lenses will be fully redesigned and possibly improved for high-resolution full-frame Sony cameras like the a7R or a7RII, or if it will be simply switching out the mount. However, the Voigtlander 10mm f/5.6 has not been available before and so it is much more probable that this lens could be made from scratch to handle higher-resolutions of the full-frame Sony a7 series.
The new lenses will have electronic connections to properly send lens data such as focal length, aperture, and focal distance to the camera body. As manual focus lenses, this is excellent because it will mean focus assist features of the Sony bodies will be enabled.
A growing trend in lenses being released lately seems to be the option to switch on and off aperture stop clicks, and these Voigtlander lenses will be no exception. The selective aperture control benefits filmmakers by making the aperture transitions during filming much more seamless with no visible stepping and no clicking noise.
All three of these Voigtlander E-mount lenses will be available in spring 2016. There’s no mention of pricing for these yet, but for reference the current Voigtlander 15mm f/4.5 M-mount lens retails for $749 and the 12mm f/5.6 M-mount goes for $699.
