This lens is now also available with Sony E-Mount and while the optical formula is the same as the M-mount version, there are a few advantages when it comes to the handling of the lens. The improved optics came at the cost of increased size and weight, as version III is noticeably bigger than it’s earlier siblings. Therefore around 2015 a third incarnation was released with a completely new optical design for Leica M-Mount. The optical formula of these lenses was the same and they not only struggled with the A7’s and A7r’s sensors but also with Leica’s digital sensors. The first still incorporated a M39 (Leica Thread Mount) while the second one was already equipped with a Leica M-Mount. There have already been three versions of this lens for Leica (or Voigtländer Bessa) cameras. ![]() Sample Images Sony A7s | Voigtländer 15mm 4.5 SWH E | f/11 | full resolution Sony A7s | Voigtländer 15mm 4.5 SWH E | f/4.5 | ISO6400 | 30s | higher resolution Last Update: Review finised (new Sample images, Use for astrophotography and Conclusion added) (05/10/16) As there are three adapted Voigtlander lenses in my basic A7s-kit – see my reviews – I simply had to try this one out!
