the Nikon D5300 is a completely successful camera and my personal high lights include:
the ease of use (even for beginners)
the perfectly functioning automatic programs, because there are some good "helpers" and "effects"
the possibility of very easy and fast to influence everything at all times and even manually
the good quality of the camera, with all the functions that the "photographer's heart" required
Ingenious Live View mode and also very good video performance
extremely fast autofocus and image stabilizer when DX lens from Nikon
the good blend define his own settings of the camera in their own menu and use whenever you need it
TIP: super solution for ISO setting is the ISO Auto, you can limit with a maximum-value such as 3200 ISO, so the pictures are really good, and show little noise. The Nikon controls then the Auto ISO values, yet does not shoot on goal. As a photographer, I will take care of just about sharpness, or time. Aperture depends whether I'm shooting with M, A or S mode.
Cool is also a built-in image editing program that I can use directly in the camera for rapid development if I want to edit RAW images immediately. JPEG and RAW at the same time, the camera anyway but that is now so standard in this price range.
Conclusion: learn and develop perfect camera for DSLR, offers everything your heart desires is very fast and makes great photos. The handling is very simple and logical set up after some time. The camera really fun and is also easily.
To the future even higher demands enough to do, I'm going to also buy a fast lens, which I see on the Nikon D5300, so this camera and hidden in her services can be fully exploited.
Here I think of the new Sigma 18-35mm F1.8 DC HSM lens type and the Sigma 50-150mm F2.8 EX DC OS HSM.
