My Viltrox EF-M2 arrived after a few weeks, finally. First of all, it didn't work with E-M1 (disappointed) but it worked with E-M5 very well as promised. The package was very nice. The box contained two screwdrivers. I was wondering why it came with a small cross type screwdriver at the first place. After the first few test shots, I knew why... Infinity focus was unavailable (off badly). There was a tiny screw on the camera mount side like Metabones'. Unscrewing it a bit and you turn the glass anti-clockwise a few times until you can focus the far objects.
From the test, EF-M2 was very sharp and AF fast with E-M5. I felt bad about I couldn't use it on E-M1. Comparing to Kipon Bav EYES, EF-M2 has a bit better image quality. I didn't touch the infinity focus adjustment screw on Kipon Bav EYES from the first day. It might affect the result (Should I adjust it too?). However, Kipon Bav EYES worked with E-M1 very well and EF-M2 couldn't.
For the price, EF-M2 is a good deal. I hope the future firmware update will fix the E-M1 compatibility issue.
Viltrox EF-M2 Advantage over Kipon Bav EYES:
- A little bit Sharper
- Better mount fitting (both lens and camera end)
- Better contact between lens to the adapter
- Camera knows your correct lens focal length after x0.71 (Correct in body IS)
- Cheaper (USD199 now)
Kipon Bav EYES Advantage over Viltrox EF-M2:
- Works with E-M1
- No need to tune infinity focus. Works right out of package.

Some people said Olympus has lots of good lenses in smaller size and why using Canon lenses. Yes, you are right if you only have m4/3 cameras. However, Olympus's Pro f/1.2 are all over-priced (cost as much as full frame Canon L Primes) and not light weight, too. Pro f/1.2 lenses are not for the people like us who have almost the whole set of Canon L Primes after 11 years of professional career. We prefer to keep using the lenses that can be for work and leisure at the same time. In 2018, it's a fact that m4/3 is still not commonly used in wedding jobs unless it can provide a usable ISO6400 photos. Before that point, I still think Olympus Pro f/1.2 lenses are over-priced.

You will find two screwdrivers inside. The small cross-type one is very important!!!
I test with 24mm f/1.4L and Sigma 35mm f/1.4 ART
The infinity focus was way off. Now it is ok after 20 mins adjustment. AF point at the line "zoom 24-105mm" on i40 flash.
E-M5 + EF-M2 + 24L
1/200s, f/1.8, ISO400
100% pixel
E-M5 + EF-M2 + 24L
100% pixel
Let's compare with Kipon Bav EYES
E-M1 + Kipon Bav EYES + 24L
1/200s, f/1.8, ISO400
100% pixel
E-M1 + Kipon Bav EYES + 24L
100% pixel: Seems like the focus shifted to backward (on the traffic light instead of the hand)
