This is one of the very sharpest lenses made by mankind. Its resolution at aperture f/4, 400 lp/mm, corresponds to the maximum resolution theoretically possible at f/4; in other words it represents the calculated 'diffraction limited' performance at this aperture. says La Vida Leica in its review of the lens. To put this in another way: Physics prohibits the construction of a lens with hight resolution power!

Before I walked away to buy it I did read a handful of other reviews, including, ones by Steve Huff and diglloyd. You find my shots taken with Biogon T* 2,8/25 ZM here. Below you find a random sample from my personal favourites.
