Park Benches -- NEX-5 & Enna Werk Lithagon 35mm f3.5. Click for larger.
While cleaning out the lenses for my annual yard sale, I unearthed three more Exaktar lenses that went missing since the last time I used them on the Canon Rebel T2i: Enna Lithagon 35mm f3.5, Lithangon 35mm f4.5, Carl Zeiss Jena Sonnar 135mm f4. Tried out the Lithagon 35mm f3.5 and found that it seems to perform slightly better than on the T2i, but it's nothing really exciting. Never really did like the Enna lenses. To me, they are like the cheap third party Japanese lenses. They do make pictures, but the optical quality is just so so.
