“Did some shooting with my X-T5 in kyoto and it was pissing rain. Between shooting I kept it tucked under my arm and surprisingly didnt have any issues afterwards! I was pleasantly surprised!!”— Idontworkhere67 on Reddit
“it performed really good and even though it was pretty cold out the battery was quite good”— Severe_Cranberry5657 on Reddit
“I got a Fuji xt5 and it was 1. Noticably heavy and the grip inadequate to make handling nice. 2. The autofocus was comically bad. I returned it and got an OM-1”— Tak_Galaman 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 rate these about evenly: 74% of 77 X-T5 owners recommend it, vs 71% of 42 for the Viltrox 27mm F1.2 Pro.
Owners point the X-T5 at travel and everyday shooters who want one capable body, and photographers who like dedicated dials and a tilting screen.
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 X-T5 is autofocus falls behind Sony, Canon, and Nikon for fast subjects, and some owners miss shots. 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.
