What does DC mean on a camera lens?

"DC" stands for Defocus Control. DC allows the photographer to change the distortion characteristics of the lens so the "look" of the out-of-focus elements in the foreground or background can be changed to produce more pleasing photos, particularly portraits.

In respect to this, what does DC mean on a Sigma lens?

Furthermore, what is the difference between Sigma DG and DC?

DC lenses are designed for cameras with an APS-C size sensor and won't cover the entire image area of a 24x36mm (Full Frame) sensor. DG lenses are designed for cameras with a 24x36mm (Full Frame) sensor but will work equally as well on a camera with an APS-C sensor.

IS II lens better than DC III?

What does F 2.8 mean in photography?

An aperture is a lens opening through which light passes on its way to the sensor. It is expressed as a ratio of the focal length (that is what the "f" stands for) and really should be written f1:2.8 instead of just f2. 8. The number is just the size of the aperture compared with the focal length.

What does mm mean on a camera lens?

This refers to the focal length of your lens. 18mm is wide angle, and 55mm is more zoomed. When you zoom your lens in, you're zooming between 18mm and 55mm. The 'mm' stands for millimeter, and this is the distance between your camera's sensor, and the point of convergence in the lens.
