| The 28 mm f/2.0 SUMMICRON-M ASPH. is the
high-speed addition to the 28 mm f/2.8 ELMARIT-M. Its
strengths become especially obvious in poor lighting,
such as at dusk or in poorly lit interiors where the lens
aperture has to be opened as wide as possible to take
an atmospheric free-hand shot without using a flash. In
order to retain the out-standing performance of the 28
mm f/2.8 ELMARIT-M even at higher speed, the constructive
effort for the 28 mm f/2.0 SUMMI-CRON-M ASPH. had to be
increased considerably. Thanks to a sophisticated optical
formula, in which special types of glass and an aspherical
surface were used, the Leica designers succeeded in surpassing
the excellent performance of the 28 mm f/2.8 ELMARIT-M.
And, although the 28 mm f/2.0 SUMMICRON-M ASPH. is one
f-stop faster than the 28 mm f/2.8 ELMARIT-M, the dimensions
and the weight are almost identical. |
