SUMMARY
Thypoch's Ksana 21mm f/3.5 Asph is an ultra-light, compact manual lens designed with a vintage aesthetic. It boasts impressive all-metal build quality and a small form factor, weighing only 131g. However, its extremely slim design can make mounting and unmounting difficult, potentially impacting the durability of the internal helicoid over time. The lens offers a 90.6° field of view and focuses down to 0.5m, with a tactile click at 0.7m for rangefinder users.
