看来28/2.8这颗最小的头大概有重大改进 The Elmarit-M 28 mm f/2.8 ASPH. is the most compact lens in the entire portfolio of Leica M-Lenses. Due to its compact size and low weight, this lens is a particular favourite of street and reportage photographers. In comparison with the earlier model, the new generation lens offers significantly reduced image field curvature, which brings considerably improved imaging performance with high resolution and extremely brilliant resolution of details. The Elmarit-M 28 mm f/2.8 ASPH.is practically distortion free from infinity to its closest focusing distance of 0.7 metres and occludes the view through the viewfinder of Leica M cameras hardly at all.
