My hobby is photography. My first DSLR camera was Nikon D70. I used Nikon DX 18-200 mm lens on my Nikon D70. Recently I switched to micro thirds camera. My camera now is Olympus OMD EM1 Mark II. I showcase some of my photos in the following photography web sites. Follow the links if you want to see my portfolios.
