NEX-5N and Wide Angle Lenses Gallery
Carl S. was generous enough to share his gallery of adapted lenses on the Sony NEX-5N. The lenses used were mostly Voigtlander lenses in Leica M mount. There are also Contax G lenses and a Canon 24mm Tilt Shift Lens.
Check out the Carl's NEX gallery which covers lenses from 15mm to 90mm focal lengths on the NEX-5N shooting the same scene. Make sure to look at the high resolution samples.
