Canon EF-M 22 mm f/ 2 STM Lens

• Very compact and light
• Bright f/2.0
• Handy 22mm focal length for general usage
• 7 rounded aperture blades
• Fulltime manual focus
• Metal lens mount
• Front element doe not rotates during focusing

Weaknesses:

• A bit slow focus speed stepping motor compared to existing USM variants
• Uncommon 43mm filter diameter
• Small and expensive lens hood
• No optical image stabilization
• Not weather sealed, front element simply moves out/in during focusing operation

Comments:

This is in my opinion a must have fixed lens that everybody should have for their Canon EOS-M cameras.

This 22mm covers about the same visual field of an fullframe 35mm lens. Its fast f/2 aperture helps in low light condition or for providing some amount of background blur.

The only dranwback is the relativly slow stepping motor that moves the focusing the internals. Not a problem in most situations but I prefer the quick USM variants.

The image quality this small prime delivers is very good for the prize.

Very Sharp lens (best ef-m family)

Slow and noisy focus
