Optical character

The Septon revives a historic Voigtländer name for a 30mm-long pancake standard lens. Its seven-element Orthometar-type design includes one aspherical and one anomalous partial-dispersion element, and at 165g it is one of the lightest full-frame E-mount primes with an f/2 aperture.

The all-metal lens has a 52mm filter thread, a 10-blade aperture and a dome-shaped metal screw-in hood whose outer 52mm thread accepts the same front cap. Electronic contacts pass EXIF data, trigger focus magnification and give the camera distance data for stabilisation.

Reviewer consensus

Early tests find excellent centre sharpness from f/2, well-controlled colour fringing and a rendering with some vintage character; the corners improve on stopping down but do not match the APO-Lanthar lenses. It is judged a sensible balance of image quality and portability rather than a resolution leader.

Out-of-focus highlights can show outlining and the background can turn busy at longer distances. Reviewers see it as a street and travel lens first, where its size matters more than corner performance.

Owner sentiment

Owners are pleased with how small it makes an A7-series body and with the tactile metal rings and hood. Many compare it favourably with cheaper pancake lenses on build and on centre sharpness.

The main reservations are the busy bokeh and the price for an f/2 manual-focus lens. Because the lens is new, long-term feedback is still limited.
