While on vacation in Mexico, I've had a chance to test a pre-production "sample" of the new DA* 50-135mm lens. I've posted a few photos to give you a sense of how the lens is likely to perform when production samples become available. All images shot with with K10D in RAW mode at both ISO 200 and 400. Exposure mode was AV with EV compensation as needed. All photos posted here are uncropped and converted with SilkyPix using the "dayight" or "cloudy" setting.
