The Croatian website fot-o-grafiti has published a review (in English) of the new Olympus ZUIKO DIGITAL ED 35-100mm lens, which has a constant aperture of f/2 throughout its range.

“Because of its range and speed, it is uniquely suited for creating shallow depth of field at the portrait range; head shots are its specialty, and it really lives up to the task. Bokeh is nothing short of fantastic; as good as anything I ever saw. The DoF characteristic is such that you can get the entire face sharp, and have rapid decomposition of background. When you shoot near to the minimum focusing distance, after 20cm or so everything melts away into uniform blur. Fashion photographers will love this one, especially for its clarity, delicate contrast and color, fantastic sharpness - and did I say bokeh? If it sounds as if we’re drooling, it’s because we are. This one is as good as it is heavy.”

Thanks to Zoltán for letting me know!
