In India, Nikon D3100 was launched in 19th August 2010..I got it in 4th Nov 2010 when the model was just new. Somone advised me for the old trusted D80 which was then available at a discounted rate.
But I ventured for the new ...For the last 3 years, I shot in every mode at the dusty rural areas of India. D3100 never failed me. But now I suspect the normal wear and tear is telling upon its performance ..so thinking about D7100..
But I would never forget the contribution of D3100 in my life.
