"I can use my lenses on an SLR camera SIGMA-D?

SIGMA I have several lenses that I use with my current Pentax SLR. I am looking for the digital world and I want to make sure I can use the lenses that I have with my new camera. Are Sigma lenses compatible with Nikon or Canon D-SLR models?

Since its Sigma lenses are Pentax K-mount lenses that are compatible with the new Pentax digital SLR cameras: K10D, K20D, K200D. A K-mount lens is not compatible with any other lens mount as Canon and Nikon.

Then the Nixon administration and Canon SLR lenses exchange?

Short answer: No. Long answer: Well, little time. Nikon lenses can physically mount on a Canon with an adapter ring. Auto Focus is lost and, in general, confirmation of discussion, but they behave as regular glasses. I do not know an adapter that allows you to do the opposite. The difference in distance between the flange focal Nikon and Canon mount involve the use of corrective lenses while Canon Nikon adapter. Adapters of this type are always expensive and always shabby, and the consensus among photographers seems simply not worth it. I hope this helps!
