Sigma DC lenses for Four Thirds DSLRs

Sigma’s range of DC lenses are designed for DSLRs with smaller 'cropped-frame' sensors, such as Four Thirds models. DC lens optics are only corrected for use on these bodies and are not compatible with larger format models.

Like all lenses, you’ll still need to take your DSLR’s field reduction factor into account. Models complying with the Four Thirds standard have a reduction factor of two times. So the general-purpose DC 18-50mm lens will deliver a field of view equivalent to a 36-100mm.
