DJI 15mm f1.7 (clones of the Leica 15mm f1.7 with lighter build and possibly different lens coating) From Lens Authority in excellent condition. This is where Lens Rentals sells their excess stuff, so it's an ex-rental. But you can add a 2 year warranty for $9 if you are worried. two copies available at time of posting at only $244. DJI 15mm f/1.7 ASPH Micro 4/3 Lens - LensAuthority I just sold my Leica 15mm f1.7 for $380 used in one day, so this seems like a good deal!
