I have been using Nikon D5200 since last two years, and I never needed any service or maintenance. One of the best product by Nikon at responsible rate.
If you are new to DSLR(professional) photography then this camera will serve at the apex.
The device is tough and wear-tear resistant. The screen can be rotated by 270 degrees as required. The look and aesthetics of the camera is no doubt marvelous. This 24 MP camera helps you capture really sharp and clear photograph. The best feature is that the device has got 39 focus points boosting you with the capacity to capture you images with best focus. You will be provided with 2 years of warranty and cleaning of the image sensor and interiors against the dust particles will be almost free.
It is one of the best camera to invest in especially you are beginner.
