PENTAX has revealed its exclusive range of digital SLR interchangeable lenses currently under development, at the Photo Imaging Expo 2008 in Tokyo.

Serious photographers will be excited about two new additions to PENTAX's DA* lens range, the SMC PENTAX-DA*55mm and SMC PENTAX-DA*60-250mm. Mirroring the other products in the range, the two lenses boast a supersonic motor which delivers smoother and quieter auto-focusing. The SMC PENTAX-DA*55mm is a uni-focal moderate-telephoto lens offering a focal length equivalent to 84.5mm in the 35mm format and a large F1.4 aperture.

The smc PENTAX-DA*60-250mm is also a telephoto zoom lens covering moderate- to super-telephoto ranges, with focal lengths equivalent to 92mm-383mm in the 35mm format and is suitable for landscapes, action or wildlife photography.

The third lens on display is the smc PENTAX-DA17-70mm which is a standard zoom lens that also provides an SDM system offering super-quiet, extra-smooth auto focus operation and is designed exclusively for PENTAX digital SLR cameras. With a 4.1-times zoom ratio and focal lengths equivalent to 26mm to 107mm in the 35mm format, the camera is perfect for all types of photography.

Both the SMC PENTAX-DA*60-250mm and SMC PENTAX-DA17-70mm are due to be launched this summer. The launch date of the SMC PENTAX-DA*55mm is still to be confirmed.
