Being owned by a commercial entity appears to do well to a well known source of Canon rumors. Here is another one in a row of recent rumors.

Rumor has it that the Canon might announced a new lens along with the rumored Canon EOS R50, the Canon RF-S 22mm f/2 STM.

The optical design of the Canon RF-S 22mm f/2 STM is said to be almost the same as the Canon EF-M 22mm f/2 STM. Indeed, this might be a port from the EF-M mount to the RF mount. No specifications leaked so far but if the optical design is similar to the EF-M 22mm, then these might (more or less) apply:

  • Moderate Wide-Angle Lens
  • Bright f/2 Lens Aperture
  • Exceptional Low-Light Performance
  • One Aspheric Lens Element
  • Built-In Stepping Motor
  • Smooth & Continuous AF
  • Seven Blade Circular Aperture
  • Short Minimum Focusing Distance of 5.9″

Stay tuned for more.

Canon EF-M 22mm f/2 STM review, it’s a no-brainer (photozone)

Well known lens testing site Photozone reviewed the Canon EF-M 22mm f/2 STM pancake lens.

Canon did a good job once more. The Canon EF-M 22mm f/2 STM may be a tiny lens but it is an impressive performer nonetheless. The center quality is great throughout the relevant aperture range and the borders are also very impressive. There’s some softness in the image corners at large apertures though and this is somewhat emphasized by a bit of field curvature. Stopping down lifts the corner performance significantly. […] Image distortions are negligible and lateral CAs are well controlled. In critical scenes you may spot some purple fringing at f/2 but that’s rather normal for a such a large aperture lens. On the downside the vignetting is on the high side even when stopped down. The bokeh is Okay for a moderate wide-angle lens but you will notice some smearing effects in difficult scenes. Read the review.

The EF-M 22mm f/2 STM is a razor-sharp lens, and the one of the two interesting lenses for the EOS M system (the other one is the EF-M 11-22mm f/4-5.6 IS STM). At $160 it’s definitely a no-brainer. It’s my prefered lens on the EOS M3. Canon Watch’s EOS M3 review is here.

Unfortunately for us, Canon managed to release just four lenses for the EOS M system. However, there is a rumor suggesting Canon may soon announce a score of new EF-M lenses.

Excellent deal at Amazon UK. The Canon EOS M with the supersharp EF-M 22mm f/2 STM pancake lens on sale for £206.51 (white only). Another very good deal is the EOS M kit with the EF-M 18-55mm IS STM lens and the Speedlite 90EX, on sale for £221.10 (silver). All EOS M kits on sale at Amazon UK are listed here.

I have the EOS M (and all lenses, plus adapter) and I love it. You get DSLR performance in a small and lightweight camera. The EOS M with the 22mm pancake lens is a no brainer, a kit you can always carry in your pocket.
