Improved picture quality through mirror lock-up in SLR cameras

High-quality SLR cameras allow you to flip the mirror up before exposure. Disruptive vibrations caused by the mirror reverberating no longer occur in the sensitive exposure period. Any type of vibration or motion during the exposure of the sensor chip or film reduces the picture quality.


Vibration measurements during image recording with a Canon EOS 350D


The image recording sensor is exposed during phases 2 and 3. No motion or vibrations should occur during this period. Any disruption in this stage considerably reduces the picture quality, particularly in the case of pictures in microscopy, macroscopy or astronomy, where the smallest detailed areas must be in focus. A camera with mirror lock-up should definitely be used in these cases.





Camera perspective for a Canon EOS 350 Digital with removed lens:

The mirror is in its original position, flipped down. In this stage, the object can be observed using the viewfinder. The recording sensor or film is protected from the light by the closed focal-plane shutter.





In the stage between phases 1 and 2, the mirror is flipped up. It is no longer possible to see the object through the viewfinder. The sensor is only protected from the ambient light by the focal-plane shutter.




The exposure takes place when the focal-plane shutter is opened in the period between phases 2 and 3. If the lens is removed, it is now possible to look directly at the recording sensor.





At the end of the exposure, the focal-plane shutter closes. The camera mirror is flipped back to its original position. The camera is now ready to take the next picture.







For the best picture quality we recommend using a remote-control release or using a computer to control the digital SLR camera. This is a sure way to avoid pictures being blurred or fuzzy due to camera shakes.
