“I have this camera. Been using it professionally for a year! It's a beast!”— @PaulStrople on YouTube
“Lack of third-party lens support is an instant dealbreaker for me.”— @steviewonderisnotblind5833 on YouTube
“The Viltrox 27mmf1.2 is around that focal length and is quite great.”— ninjagowoo on Reddit
“Viltrox 27mmf1.2 pro. sharpness on par with the new xf23mmf1.4. The only downside is the size and weight(600g), it weighs more than XT5. It is cheaper than original modern primes but offers same quality.”— MYFAILEDMID on Reddit
“I felt 27 (40 equivalent) was not wide enough for indoor/easily framing multiple people, making 23 more versatile + the lens would be much heavier and I knew I would never use it because of that.”— Fino831 on Reddit

Owners point the Canon EOS R6 Mark II at hybrid shooters wanting strong photo and video, and sports and action shooters needing high keeper rates.
Owners point the Viltrox 27mm F1.2 Pro at everyday/street shooters wanting one sharp fast prime as their main walk-around lens, and wedding and event photographers needing a fast aperture, versatile focal length.
The most-cited downside of the Canon EOS R6 Mark II is video stabilization issues: IBIS "jello," and you can't disable IBIS while keeping lens IS. For the Viltrox 27mm F1.2 Pro, it's large and heavy for the system, noticeably bigger and heavier than the camera body and lighter alternatives like the 23mm.
