- the program for reading exif-files
The Nikon and Pentax all information about how many times the camera clicked the shutter, is stored in a special exif file. To view it, it is sufficient to find a program that can read such files and to decrypt them. It is not difficult, suitable, for example, Opanda EXIF or ShowExif, there are other applications. They are all small and simple. The program will need to open the image that was shot on the camera last. In the properties displayed by the app, will the parameter "Total Number of Shutter Releases", in front of which is indicated the numeric value is the mileage of the camera.
Manufacturers Canon have not decided exactly whether they support the exif format, so about some cameras you can find out the whole story with the meta-files, and some not. If the camera whose mileage you are interested in does not have the capability to know the number of shots, you have two options. First – inspect the camera. Most likely, if it was actively used, on appearance it will be noticeable. Or you can give the camera to the service center, there will be able to determine the age of the camera, this method is more reliable and more accurate.
If we are talking about the Olympus camera, in this case, the approach is quite tricky. If you do not know, never it is impossible to guess how verified have camera run. You will need to make several steps. First turn on the camera. Then open the card cover memory. Then simultaneously press two buttons, first "play" (in some models 'menu'), the second "ok". Then take turns to press buttons up, down, left, right. Press the shutter button, and then up again. This procedure will allow you to learn about how many pictures she clicked off the camera.
If the professional camera, the normal mileage is about 150 thousand personnel. For Amateur cameras limit – about 50 thousand photos.
If you buy a used camera, it is also important to know what conditions were made for photos. If filmed mostly in the Studio, and the lifetime of the shutter is much more.
Advice 2: How to know the mileage of the camera
Intuitively, the mileage is the degree of deterioration of the camera. Cars it is measured in kilometers. The cameras – the number of shutter clicks. Shutter any camera has its own resources and will eventually wear out. Cameras have easier mileage less than professional. How to know the mileage on your camera? Consider the case of two fotoseventos: Nikon and Canon.
All meta-data about images stored in encrypted form. To view them, just by looking in the document properties, it is impossible. You will have to use special software. And for each manufacturer's cameras to look for its program.
Let's start with Nikon. To view meta-data, you can use the program ShowExif. It weighs less than 1Mb and requires no installation, what is very convenient. Just run the program. In the left window, specify the path to the folder with the latest photos. In the middle - will appear in the photos themselves. Select the last one. In the right window will show all the meta data about the picture. Among them, almost at the end look for the line "Total Number of Shutter Releases". The figure in this row is the number of the last shutter. If it says 50, it means your mileage is 50 frames. If written 23824, then the shutter of your camera clicked just enough time.
As for Canon, everything is complicated. Most people recommend with cameras of this brand to contact the service center. They argue that the only way you can determine the mileage of the camera. However, there is a chance to learn meta-data and samostoyatelno using the program EOS Info. The program's interface is almost the same as ShowExif. However, it should be borne in mind that the program can read data only on certain Canon cameras. There is also a chance to get meta-data through ShowExif. Sometimes it works. Apparently, it is difficult to come to a specific conclusion. And you better do with the camera to go to service center and get accurate data on mileage of your camera.
