The Single Reflex Lens (SLR) camera uses a mirror to reflect light from the object onto the sensor. The digital SLR differs from the SLR camera in that it uses electronics to do what the SLR camera does manually. Thus, the quality of the images is much better in the DSLR cameras. Here is a list of the things you must consider if you want to buy a DSLR camera.
Check the feel of the camera
The first thing to do is to, in a mild way; bounce the camera in your hand. It must feel easy and well balanced. That is important because you will want to align the camera in a specific manner to get a photograph and if you do not have a good feel, then you will not get good photographs.
Work the controls
Keep the camera lightly balanced and work the controls. These are the Shutter Speed and White Balance for starters. They must have an alien feel when you change them around. Instead, they must feel natural. Check the drive mode and the self-timer to see if they work in a smooth way. Fiddle around with the exposure settings, change the metering and try to work the focus. If they work well, then you have the right model. If not, try another model.
Check the video recording
Even if you are not planning on shooting any videos, you will in time use the video recording function. Most DSLR cameras have full HD 1080p video recording feature. But, there are a few that have only 720p or non-HD recording. Every brand has a different frame rate for recording. The higher frame rates give smoother output.
Confirm the modes available
The DSLR camera will have all standard features such as Action, Portrait, Landscape, and Night modes. A few of the cameras will also have features such as Auto, Guide, and Panorama. The Guide function is especially helpful if one is a beginner. It will walk you through the working of the camera which helps you become an expert in no time at all. But, working your DSLR camera is easy if you use the Auto mode during the initial phases when you are learning about the controls.
Know about sensor size
The quality of the photograph depends on the size of the sensor in the camera. The biggest sensor is the full-frame sensor present that is equivalent to the 35 mm film. The size of the sensor is 36×24 mm. Entry level cameras have a smaller size sensor and crop sensors. The APS-C sensor for all brands except the Canon is 23.6×15.6 mm. The Canon has a smaller sensor at 22.2×14.8 mm. Another common sensor is the Four Thirds that measure 17.3×13 mm. The larger sensors cost more and deliver better pictures.
See the megapixel resolution
The megapixel resolution does matter but not as much as the sensor size. To print clear pictures of standard size, you need at most a resolution of 7 megapixels. Most of the entry level cameras have 12 megapixels or more so you need not worry about this aspect at all.
Now, you know what to look for in your camera. You only need to see that the camera has all the basic features.
