“I've been very happy with the footage. A little post work and it's great. I certainly would not use it as my primary cam but for the use I described, I am happy with the investment.”— AndrewThomasPhoto on Reddit
“Often with the pocket3 it's not even worth the time to shoot in d-log and color grade. Standard is what I typically use and still looks great with a fraction of the editing effort.”— RidexSDS on Reddit
“My major complaint with the OP3 is its difficulty in handling the "blues." I'm not sure if it's a common complaint but I've been finding it hard to deal with the "blues" from all my clips actually.”— kuyand 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

The most-cited downside of the Osmo Pocket 3 is getting good-looking footage takes careful lighting, settings, and grading, and some owners struggle with blues and shadows. 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.
