Three lenses have been announced in the new DT series, which are compatible with Dynax digital SLR cameras that feature an APS-C CCD.

Covered in a special coating to reduce the effects of flare, each lens is designed specifically for use with a digital camera .They feature a round aperture that creates smooth gradations, which are designed to enhance a defocused image. Each lens includes a distance encoder that works out the distance to the subject, and an advanced distance integration (ADI) calculates optimum flash settings.
