EF-M 32mm f/1.4 STM is a Five Star-lens!

I was about to pull the trigger on the EF-M 32mm f/1.4. As I was doing researched on the 32mm lens, I came across a lot of information about a speed booster from Viltrox being paired with the EF 50mm f/1.8 lens. On paper, it sounds like the speed booster/50mm combo should yield the same results as the native EF-M 32mm f/1.4. Is that actually the case or is this a prime example (pun intended) of "you get what you pay for"? The speed booster/EF lens combo is currently priced out at $281 vs the $480 price tag of the 32mm.

The Speedbooster has poor optical qualities and other technical issues in relation to vignetting/falloff and noticable image softening.  Sticking one on your EOS M50 will likely prove problematic and the image quality with be affected dramatically in a negative way.  Viltrox make some really cheap products and there's a reason why they're so affordable. I bought a couple of their tele-extender tubes and the build quality was/is rubbish.  Some members have already tried a speedbooster (I think it was a Viltrox) and were very unimpressed with the resulting images.

Canon recently lodged a patent for their own speed-booster so it's possible we may possibly see one in the near future.  But it will probably be for EF lenses to enable them a native view on the smaller APS-C sensor.  Using one with an EF-M lens would likely produce strong aberration and extreme vignetting.

You can search for past subjects (ie Speedboosters) on the forums or feel free to start a thread and ask members who have used a Speedbooster what their experiences were.  The EOS M forum is a great place to start.
