Even while the EOS R system and the RF mount have been well received, this is not Canon’s first foray into the mirrorless camera industry.
This distinction belongs to the EOS M system, however it appears (as expected) that the company is continuing to phase out the RF mount in favor of the RF mount for its cameras and lenses.
Canon already announced that it will discontinue production of the EF-M 55-200mm f/4.5-6.3 IS and the EF-M 18-150mm f/3.5-6.3 IS STM lenses. This isn’t surprising given that both of these lenses have RF mount near-direct equivalents in the form of the RF-S 18-150mm f/3.5-6.3 IS STM and the RF-S 55-210mm f/5-7.1 IS STM.
Only five EF-M lenses remain, none of which are longer than 45 millimeters:
- EF-M 11-22mm f/4-5.6 IS STM
- EF-M 15-45mm f/3.5-6.3 IS STM
- EF-M 22mm f/2 STM
- EF-M 28mm f/3.5 IS STM
- EF-M 32mm f/1.4 STM
Canon has not released a new EOS M camera since late 2020, implying that the company is ceasing production of the system while also developing the RF-S mount as a potential successor. Having said that, the majority of the business’s APS-C mirrorless cameras and lenses have received favorable feedback, and it looks that the company is committed to expanding this product line.
