ABOUT THE LENSES
The sd Quattro H uses SIGMA SA mount. The usable lenses are SIGMA
SA mount interchangeable lenses.
Depending on the release date of the lens, updating the lens firmware
may be required. Updating the camera firmware may also be required.
Please check our website for the latest information of the corresponding
lens.

The SIGMA sd Quattro H incorporates the APS-H sized imager. In order
to take full advantage of the capability of the image sensor, it is
recommended to use DG lenses (for 35mm full size). It is possible to use
DC lenses (for APS-C) in DC Crop Mode, which limits the recording area
of the image sensor for APS-C size.
CAUTION !!
On the mount surface of the lens, there are a number of electrical
contacts. Keep them clean to ensure proper connection. To avoid
damaging them, be sure to place the lens on its front end when it is off
the camera.
