Every day on the shelves we see an increasing variety of camera models. If this is your first time buying a camera, you need to know the basic specifications to check upon purchase. The test we offer is suitable for any digital or SLR camera. The purpose of this test is to ensure the quality of the products offered.
Instructions
Step 1
First you need to check the shutter lag. In order to immediately determine the list of cameras, ask the sales assistant to check the shutter lag. All you need is to set the maximum quality of shooting on the camera, as well as enable all possible functions. Next, take a picture of any object, if the screen went out for more than one second, then this is a clear sign that this camera is not suitable for you.
Step 2
To make sure that all the pixels on the sensor are working correctly, ask the consultant to take a photo in the dark with the flash off. If there are "cold" or "hot" pixels on the matrix, then looking at the resulting image, you will see colored dots. Do not trust the seller if he claims that it is a speck of dust. After all, dust particles have blurred edges when shooting. Check the entire photo carefully, if everything is in order, then you can proceed to the next step.
Step 3
When using magnification, the scale should change smoothly, without jerking. The main thing is that you do not hear any extraneous noise.
Step 4
The lens works fine when the blur in the image gradually increases from the center to the edges of the photo. Therefore, you need to evaluate all corners of the frame at the same time or in pairs. For the test, you can take a photo of a piece of text. If there are significant differences in focus, then the lens is not properly adjusted.
