I have had this camera for more than two years. During this time, it has established itself as a reliable tool for taking good pictures. Of course, now the requirements have increased. Therefore: 1. The minimum ISO could be smaller. But for a start, this is excellent) Yes, and for that kind of money you can’t wish otherwise. 2. I plan to switch to full frame. I don't know what to do with cropped lenses. But without the d3100, I would not have understood all this, so I consider the purchase more than successful.
