Panasonic/Leica's compact wide prime — same as ID 1009, possible duplicate of the 15mm f/1.7.
The Leica DG Summilux 15mm f/1.7 ASPH. is the Panasonic-made Leica-certified compact wide prime for Micro Four Thirds providing 30mm equivalent at f/1.7. The Summilux designation indicates Leica's optical quality certification.
Optically very good — Leica Summilux certified with sharp results from f/2.5 and pleasant rendering at f/1.7. The 30mm equivalent provides a slightly-wide-of-normal perspective excellent for street and environmental photography on MFT cameras.
Micro Four Thirds mount with 46mm filter thread at just 115g — incredibly compact for any interchangeable lens. No weather sealing on the original version. Minimum focus distance 20cm. Available in black and silver finishes.
Available used at budget to mid-range prices — excellent value for Leica-certified optics. The Olympus 17mm f/1.8 is at a slightly different focal length. A charming and compact wide prime that pairs beautifully with small MFT bodies.
