9mm f/1.7 prime that closes to 3.74 inches
The Leica DG Summilux designation on this 9mm carries real optical weight. Panasonic loaded the 12-element, 9-group formula with two aspherical elements, two ED elements, and one ultra-high refractive index element to keep aberrations controlled at f/1.7 across a field that, on Micro Four Thirds, translates to an 18mm equivalent angle of view. That is genuinely wide, and the 7-blade circular diaphragm holds up its end of the bargain in out-of-focus rendering.
The half-macro capability is the detail that separates this lens from typical wide-angle primes. A minimum focusing distance of 3.74 inches and 0.25x maximum magnification means you can fill the frame with a flower, a coin, or a plate of food without stepping back to set up a macro kit. Internal focus keeps the barrel length fixed throughout, which matters when you are working close and do not want the front element drifting toward your subject. The micromotor-driven autofocus runs near-silent, and the lens supports micro-step aperture control for smooth, stepless exposure transitions during video recording.
At 130 grams and 52mm long, this lens disappears into a kit bag. Weather sealing rounds out the package for a fast, sealed, close-focusing wide prime that does not ask you to compromise reach, light gathering, or weather readiness.
Who It's For
Travel and street photographers working Micro Four Thirds bodies get a fast f/1.7 aperture that handles low-light alleys and evening markets without a tripod. Food and product shooters benefit directly from the 3.74-inch minimum focus distance, which brings small subjects into serious close-up range without a dedicated macro lens. Environmental portrait and documentary filmmakers will rely on the near-silent autofocus and micro-step aperture control to keep footage clean through changing exposures. Landscape photographers shooting from a weather-sealed body can count on the sealed construction when conditions shift.

FAQ
- What's the 35mm equivalent focal length?
- 18mm. The 9mm native focal length on Micro Four Thirds translates to an 18mm angle of view on full frame, giving you genuine wide-angle coverage without the bulk of a larger mount system.
- Can you actually use this for macro work?
- Yes, within limits. The 0.25x maximum magnification and 3.74-inch minimum focus distance let you frame small subjects-flowers, coins, food-without a dedicated macro lens, but it's half-macro, not true 1:1 reproduction.
- How does autofocus perform during video?
- The micromotor AF is near-silent and pairs with micro-step aperture control for stepless exposure transitions, making it designed-in for smooth video work without audio interference.
- Is the lens weather sealed?
- Yes. It has full weather sealing, so it handles dust and moisture the same way you'd expect from a professional optic on this platform.
- What's the optical design doing to hold f/1.7 wide open?
- Two aspherical elements, two ED elements, and one ultra-high refractive index element keep aberrations in check across the 12-element, 9-group formula. The circular 7-blade diaphragm handles out-of-focus rendering at wide apertures.
- Does internal focus matter for a wide prime?
- Yes. The barrel stays fixed during focusing, which prevents the front element from drifting toward your subject when working close. It also keeps autofocus fast and silent.
- How much does it weigh and how does it pack?
- 130 grams and 52mm long. It's small enough that it adds almost nothing to a kit bag, making it practical for travel and street work where lens swaps matter.
