I am writing from the position of an experienced amateur, a little engaged in commerce. The camera cannot be sold! So I carry it as a spare for commercial shootings and for any extreme and travel for slaughter. I've been carrying for a long time. A very strange product from Nikon. Very popular and very strange. Not the best matrix, strange operation of automation, dangling buttons. d5100 is now a drop more expensive and much better. Nevertheless, the d3100 never failed, there was not a single glitch, it allows you to remove everything that a SLR can remove. If it were not for the peculiar, slightly dirty color reproduction and incorrect skintones, I would even love him. And so I want to sell. But it's not for sale! For 4 months the ad has been hanging at a low price. Not a single call! No one!
