The Nikon D3100 is an exceptional camera for its class and may be purchased for an amount that is totally acceptable. You get everything that a contemporary entry-level DSLR can offer from the D3100, including a high-quality picture, the ability to shoot FullHD video, and good performance from all of the camera's systems, in addition to a few nice bonuses in the form of convenient controls and a "smart" GUIDE shooting assistant. Has some pros 1) The focusing and metering functions work fairly well for such a basic camera. 2) A nifty shooting aid mode called GUIDE. 3) Superb camera ergonomics and convenient use. 4) Have the capability to record Full HD video in great quality while also having the ability to autofocus while filming. The Nikon D3100 is the first single-lens reflex camera (SLR) that enables the user to disable "blinking." The user can modify the screen refresh rate in the settings to either 50 or 60 Hertz. 1) The screen does not rotate in any direction. 2) Exposure bracketing and white balance bracketing are not options that are available to you. 3) There is no focusing motor present.
