The EF 40mm f/2.8 STM was announced in June 2012, alongside the EOS 650D (Rebel T4i) SLR and EF-S 18-135mm f/3.5-5.6 IS STM zoom. These two lenses were Canon's first to use a linear stepper motor for focusing, giving rise to the 'STM' designation; this motor type allows silent refocusing during movie recording, and has therefore become widely-used in lenses for mirrorless cameras. This means that in principle the 40mm STM should be well-suited to working with the hybrid AF systems in Canon's recent cameras, including the 650D and its replacement the EOS 700D (Rebel T5i), the EOS M mirrorless model, and the diminutive EOS 100D (Rebel SL1).Read more
