“It does have some faults (short battery life, no IBIS, single card slot), but it is a powerhouse in a small package. I've been nothing but impressed with its performance using the RF50mm F1.8 STM "nifty fifty" lens”— brielkate on Reddit
“Ich habe mit meiner Canon EOS R8 schon mehr als brauchbare Bilder Nachts im Licht einer Straßenlaterne gemacht (allerdings auch mit f1.4). Und dem Autofokus reicht sogar Mondlicht zum Fokussieren aus.”— Gentlemansuchti on Reddit
“I was at a christening today and brought my Canon EOS R8 which proceeded to crap itself and not work for the majority of the day, so… I do not recommend that.”— Opspin on Reddit
“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
Real owners lean toward the Canon EOS R8: 82% of 67 owners recommend it, vs 71% of 42 for the Viltrox 27mm F1.2 Pro.
Owners point the Canon EOS R8 at hobbyists wanting full-frame image quality in a compact, lightweight body, and beginners upgrading from crop-sensor or older DSLRs like the 5D/6D.
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 R8 is no in-body image stabilization (IBIS), which several owners call the single biggest reason to hesitate or to consider the R6 II instead, even though most say lens/digital stabilization compensates well enough. 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.
