$977.00
Olympus 17mm f/1.2 PRO: the 34mm equivalent built for MFT shooters who work fast.
At 34mm equivalent, this lens sits in that useful middle ground between a wide-angle and a standard prime, wide enough for environmental portraits and street work, tight enough to isolate a subject against a scene. The f/1.2 maximum aperture gives you real low-light latitude without stacking ISO, and the nine-blade aperture produces smooth, gradual falloff when you're working with shallow depth of field at close range. Minimum focusing distance is 20 cm, so tight detail work is on the table as well.
The optical formula runs 15 elements in 11 groups, combining extra-low dispersion elements, aspherical elements, high refractive index glass, and an Advanced ED-DSA element that keeps physical size down without trading away correction quality. The result is strong control over both chromatic and spherical aberrations, and Z Coating Nano on individual elements keeps flare and ghosting in check when shooting toward light sources. The autofocus is quiet and fast, which matters in documentary and event work where audible AF draw would pull attention.
Splash-proof and dust-proof metal construction means this lens travels as confidently as the OM System bodies it pairs with. At 390 g and 87 mm long, it carries well on a full day of shooting, a legitimate pro-grade prime that earns its place in the bag on optical merit alone.
Who It's For
Street and documentary photographers working in mixed or low light will appreciate the f/1.2 aperture for available-light shooting without leaning on high ISO. Portrait shooters gain shallow depth-of-field control with natural rendering at the 34mm equivalent field of view. Event photographers benefit from the quiet, fast autofocus in situations where discretion matters. Travel shooters who need weather-sealed gear and a compact profile can run this lens through rain and dust with confidence, given the splash-proof and dust-proof metal construction.

FAQ
- What's the real-world equivalent focal length for MFT bodies?
- 34mm - the standard field of view for environmental portraits and street work. Olympus crops sensor is 2x, so 17mm becomes 34mm equivalent.
- How close can you focus with this lens?
- 20 cm (7.87 inches) minimum focusing distance. That's tight enough for detail work and extreme close-ups without adding extension tubes.
- Does the f/1.2 aperture actually deliver in low light?
- Yes. You're working 2 stops faster than an f/2.8 prime, which means you're holding shutter speed without stacking ISO in rooms where most lenses would demand 3200+.
- What does the nine-blade aperture do for bokeh?
- Produces smooth, gradual falloff when you're shooting wide open or near wide open. More blades mean rounder aperture shape and less nervous bokeh ball edges.
- Why is the ED-DSA element worth the markup?
- It handles spherical aberration correction without adding physical bulk. This lens is 87mm long while delivering f/1.2 performance on a 17mm focal length - that's a real engineering trade-off in your favor.
- Is autofocus quiet enough for video and events?
- Fast and quiet by design. Olympus engineered this specifically for documentary and event work where AF noise would be picked up on audio.
- What does splash-proof and dust-proof actually mean here?
- Metal construction with sealed seams. Not full weather-sealing like Canon or Sony pro lenses, but solid enough for spray, light rain, and dusty environments without worry.
