OM System M.Zuiko PRO V335260BW000 25mm
The 19-element optical design with three ED elements and a bright f/1.2 aperture delivers exceptional sharpness and smooth bokeh from a 50mm equivalent field of view. Its weather-sealed, 410g build and manual focus clutch provide a tactile, all-condition shooting experience rare in the Micro Four Thirds system. This lens is best for portrait photographers who need shallow depth-of-field control and reliable autofocus in a compact, rugged package.
Snapshot
The 30-Second Version
The OM System 25mm f/1.2 PRO delivers stunning sharpness and some of the best bokeh in the MFT world. It's a weather-sealed tank built for portrait perfection, not travel snaps. If you can stomach the price and the lack of stabilization, this is a top-tier prime.

The proof
Performance
Sharpness is the star of the show here. It's exceptional from f/1.2 through f/5.6, which puts it in the top tier of our optical rankings. The bokeh is a real standout too, sitting near the absolute best in our database thanks to that bright aperture and a 9-blade diaphragm. Autofocus is solid and reliable, though not the fastest we've ever tested, landing right in the middle of the pack. The lack of built-in stabilization is a bit of a letdown, so you'll want a body with good IBIS to really get the most out of it in low light.

vs Competition
Stacked against the competition, this lens is in a weird spot. The Sigma 16-300mm and Tamron 18-300mm are superzooms that prioritize versatility over sheer image quality, so they're not even playing the same game. The Canon RF 28-70mm f/2.8 is a fantastic zoom, but it can't touch this OM System's f/1.2 light gathering or bokeh. If you need a one-lens-does-all solution, look elsewhere. If you want the best possible portrait rendering and low-light performance on MFT, this prime smokes those zooms.

Price
Value & Pricing
Pricing is all over the map, with a spread from $1,300 to a frankly absurd $285,200 across vendors, so definitely shop around. For the realistic ~$1,300 price point, you're paying a premium for that f/1.2 aperture and pro-level weather sealing. It's an investment, but if you shoot portraits or events on Micro Four Thirds, the image quality justifies the cost. This is a lens you buy once and keep for a decade.

Overview
This is the lens that makes Micro Four Thirds owners feel like they're cheating. The OM System 25mm f/1.2 PRO is a 50mm equivalent prime that opens up to a ridiculously bright f/1.2, and it's sharp right from that max aperture. We're talking about a piece of glass built to shrug off rain, dust, and freezing temps, all while delivering some of the creamiest bokeh we've seen on the system.
Common Questions
Q: Is this the same lens as the old Olympus 25mm f/1.2 PRO?
Yes, it's identical optically and mechanically. The manufacturer officially rebranded from Olympus to OM System, so the lens just got a new nameplate.
Q: Does this lens work well for video?
It can produce beautiful footage with that shallow depth of field, but the lack of optical stabilization means you'll need a camera with strong in-body stabilization or a gimbal for smooth handheld shots.
Who Should Skip This
Travel and street photographers should probably pass. The 410g weight and lack of stabilization make it less ideal for quick, on-the-go shooting, and the 50mm equivalent field of view can feel tight in tight spaces. If you need a compact, versatile walkaround lens, this isn't it.
Verdict
This is a specialist's lens, and it knows it. Portrait photographers and anyone who craves shallow depth of field on Micro Four Thirds will be in heaven. The sharpness and bokeh are genuinely best-in-class, and the weather sealing means you can chase that golden hour light through a drizzle without a second thought. It's not for video run-and-gun or casual vacation snaps, but for making images with a distinct, professional look, it's a knockout.
