I started learning photography in 2013 with a Nikon V1 mirrorless system camera. I've collected a nice set of lenses and I bought a second V1 body. When my daughter started learning photography, she took over most of my Nikon lenses and bodies, and then I had a chance to build another camera system. Right on time Sony announced A7 and just before 2013 Christmas, I bought my A7 with the FE 28-70 kit lens. Since then I've bought a number of old manual focus lenses: Canon FD (24mm/f1.4L, 85mm/f1.2L, 80-200mm/f4L), Nikon AIS (180mm/f2.8), Minolta MD (16mm/f2.8 fisheye, 20mm/f2.8, 28mm/f2, 35-70mm/f3.5 macro), Olympus OM (50mm/f1.8, 55mm/f1.2, 200mm/f4), Olympus PEN (150mm/f4) lenses. I have the Sony 10-18mm/f4 lens, which works quite nicely on the A7.
