General Questions A dealer tells me that he buys special "Pro" or "Gold Series" type lenses directly from the Sigma factory, and that they are better and more expensive than the Sigma lenses, which other dealers are selling.

Yes, as long as the lens in the requested mount has been released by Sigma as a product. Does the serial number change after the mount conversion? The serial number will remain the same as the original lens. Each mount has an OS and non-OS version, how will each scenario be handled?

How can I request this service? How long after my lens purchase can I consider the Mount Conversion Service?

DC lenses have an image circle that covers APS-C size image sensors, therefore they are not for use on digital cameras having image sensors larger than APS-C size or on 35 mm or APS film cameras, as vignetting will occur.

To find the 35mm camera equivalent focal length, multiply the DC lens focal length by the "crop factor" digital multiplier of the brand of DSLR camera on which the lens will be used. Remarkable image rendition is achieved by comprehensive correction of aberrations and distortions. See for yourself. Page: 1 2 3 4 Next. Zoom Prime Only Zoom Only. Blog Spotlight. Nov 9,
