How to adjust the focus of Rollei 3.5e if it is not accurate

The camera is out of focus, which is often said to be out of focus. Then you must first determine whether it is the camera body or the lens: 1. If the camera is out of focus no matter what lens you change, then you can be sure that it is the camera body that is out of focus. This must be Go to the after-sales service station and have it debugged by professionals. 2. If some lenses are out of focus while others are not, then it is likely that the lens is out of focus (generally the lens from a subsidiary factory has a higher probability of being out of focus). The following method can be used to test: use the center point to focus, and the shooting distance is two meters. Go to the Internet and print out a target drawing for testing out-of-focus, put on a tripod and take a few pictures to try. The focus is indeed out of focus, and the direction and distance of out-of-focus are fixed and the distance is very small, so you can adjust it when shooting (for example Run forward and use the ears as the focus point when taking portraits; run backward and use the tip of the nose as the focus point, etc.). Most high-end digital SLRs have focus fine-tuning to solve this problem. If the focusing distance and direction are irregular, you also need to go to the maintenance station for debugging. 3. If the lens of the sub-factory is out of focus, you can go to the after-sales service of the brand for free debugging. 4. Some low-end fixed-focus heads (including original ones) occasionally lose focus when the aperture is fully opened. This can usually be solved by shrinking the aperture by one stop.
