Imagine this creepy picture: you bought a DSLR camera, and the photos from it come out blurry. But if you look closely, the camera is focused, just not at all on the object you were aiming at. If the focus has "crawled" further than the object back to the background, then your diagnosis is back focus. This is not fatal and can be fixed.
Instructions
Step 1
Take your camera to a certified service center. But this can not always be done quickly - far away or once. Yes, and it costs a lot of money to repair and adjust photographic equipment, but if this is not a problem, this option will be the most suitable for beginners.
Step 2
Perform mechanical camera alignment. Most DSLR cameras have one or two eccentrics under the mirror to align the AF plane. If you move them, the field of focus will change. The difficulty of the operation is that it turns out to turn ah only at a small angle, because the walls interfere. To intercept, you will need different keys bent at different angles. You will also need a small mirror to photograph / remember the original position of the eccentric so that you can put everything back if necessary.
Step 3
Attach the front lens to the pivot slots with three screws. When rotating, the lens goes down a little or rises up. This is the essence of the adjustment. Carefully peel off the decorative ring to access the screws. This can be done by gently prying it off with the needle. Rotate the lens and re-tighten the screws lightly. If you turn the lens counterclockwise, the screws should be unscrewed a little more, then that the frame will rise.
Step 4
If you cannot eliminate back focus mechanically, then when shooting from two to three meters, transfer your body weight to your front leg. Bring it slightly forward and focus. Without releasing the shutter button, regain your body weight and press the “shutter” all the way. The camera will move 20-30 cm back. Which will be enough to compensate for the average back focus error.
Step 5
Keep in mind that all attempts to manually adjust the focus yourself will void your free warranty service, so you do this at your own risk.
