“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
