Thypoch’s New Ksana 21mm f/3.5 Lens

credits: Thypoch

Thypoch just added a new ultra-wide, manual-focus lens to its Leica M lineup with the Ksana 21mm f/3.5 ASPH. It covers a full-frame image circle and delivers a 90.6-degree diagonal field of view, which puts it in the usual 21mm rangefinder category. Physically it is relatively small at about 27.3mm long and weighing 131 grams. The lens uses a 39mm filter thread, has a 42mm front diameter, and is offered in both black and silver finishes.

On the optical side, the Ksana uses eight elements in six groups and is rated from f/3.5 to f/22. Thypoch lists a gold coating on the glass to help manage reflections and stray light, which is especially relevant for wide-angle rangefinder lenses where the rear element sits close to the sensor. The nine-blade aperture should give reasonably round highlights when stopped down, though at this focal length depth of field is already fairly deep.

Minimum focusing distance is 0.5 meters measured from the sensor plane, which is about as close as M-mount rangefinder coupling allows. Full-frame coverage also means it works across current Leica M bodies without cropping or vignetting. Pricing is sitting at $550/€480.95.
