LEICA DG VARIO-ELMARIT 50-200mm/F2.8-4.0 ASPH./POWER O.I.S. H-ES50200. I used this lens primarily with my OM-1m2 for bird photography for about six months. While I mainly used the OM 300mm F4, this lens was a secondary option, but its light weight and image quality are undeniably excellent. The lens barrel is slim, making it feel surprisingly light, and the image stabilization on the OM-1m2 is more than sufficient. The exterior shows some signs of use, but since it was used as a secondary lens, it's still in good condition as shown in the photos. I've taken good care of it. If you're interested, please feel free to inquire.
