Can a DT lens be used on full-frame digital camera?

    DT lenses can only be used with certain restrictions on full-frame digital cameras. These types of lenses are specifically designed for use with digital cameras that have an APS-C size image sensor; APS-C image sensors are smaller than the image sensors in full-frame digital cameras.

    When a DT lens is attached to a full-frame digital camera, the entire surface of the image sensor cannot be used.

    For mounting a DT lens on an E-mount camera, a lens mount adapter is required (LA-EA-series).

    The camera will only use part of the image sensor that is equivalent in size to an APS-C sensor.  The image size is automatically set to that of the APS-C size setting. Also, although it will not show up in the recorded images, vignetting will be seen in the viewfinder of the DSLR-A900/DSLR-A850 when shooting wide-angle pictures. In addition, exposure accuracy is not guaranteed with DT lenses in certain shooting situations when using the DSLR-A900/DSLR-A850.


    NOTE: This is an example of vignetting as seen in an optical viewfinder .
