Fourteen elements in 8 groups. Seven aperture blades. The 43mm filter thread. At 235g the lens is moderate. Minimum focus distance of 0.23m (0.25× magnification).

The EF-M 32mm f/1.4 STM is Canon's fastest prime for the EOS M system: f/1.4 at the 51mm equivalent perspective covers the standard normal field of view with shallow depth-of-field and low-light capability. The STM motor enables quiet AF for video recording on EOS M bodies with Dual Pixel AF. The 43mm filter thread is smaller than typical 50mm primes, keeping the lens compact.
On the used market the Canon EF-M 32mm f/1.4 STM is available at Canon EOS M fast prime pricing. Condition checks: STM AF response, 43mm front element for marks. APS-C only (EF-M). Compatible with all Canon EOS M EF-M mount bodies.
