The next step is how to test the mirrorcamera when buying, view its lens. As a rule, such devices are equipped with a lens with "rings". They are designed to adjust the focus and zoom. Twist them in different directions - the rings should turn easily and do not make creaking and crunchy sounds. To check the lens, you need good lighting. Turn the lens at different angles: chipped, opacity and scratches can not be seen right away. It is worth looking for as defects in the optical system (for example, condensation accumulated between the lenses), and faults in the mechanics. In particular, during such a check, it is easy to detect damage to the diaphragm blades.


Be sure to check the condition of all connectors,which is equipped with a digital SLR camera. This is the Micro USB connector, and the hole for the memory card, and everyone else. On the damaged connector, you can easily notice cracks. In this case, the contact is unreliable, the card or cable will wobble, drop out.

First of all, it is necessary to check the CCD matrix onthe presence of so-called "stuck" pixels. To do this, take a picture by closing the lens with a light-tight lid. Keep the photo in the highest quality available in the model. Examine the picture on the computer with a large approximation - so you can easily detect the defects of the CCD.

Check the camera for a mirrordefocusing. To do this, remove several items that are at different distances from you, as well as the same object from different distances. For greater accuracy, shoot from any stable surface: so you can get rid of extraneous noise and vibration.

An important test in how to test a mirror camera when buying, will be shooting in low light conditions and macro photography.

In the latter mode, the camera must confidentlypoint to an object deleted by 10-20 cm. If this does not happen, and you know that this mode will be used often enough, you should search for an alternative. Be sure to make sure that the camera focuses well in a room illuminated only by ordinary incandescent lamps.
