photokina Special Coverage; Rangefinder Cameras: The Golden Age Is Upon Us
There are also two new lenses, both of which can be used on film as well as
digital bodies. These are a 16-18-21mm f/4
TRI-ELMAR (21-24-28mm equivalent) and a 28mm f/2.8 (38mm equivalent) aspheric
“standard” lens. The former is truly astonishing, though also very
expensive; it means that with just the two TRI-ELMARs, the Leica photographer
can now have six focal lengths, 16-90mm.
Like all new M-fit lenses, the new TRI-ELMAR and 28mm f/2.8 ASPH are supplied
with 6-bit bar coding on the lens mount. This transfers metadata and also allows
native software to “tweak” the image to correct vignetting (more
of a problem with older lenses designed for film) and possibly introduce other
improvements. Many older lenses can be retrofitted with the bar coding; the
advantage in doing so will vary from lens to lens.
In other words, this is the wide angle Bessa par excellence. The downside
is that the extremely small viewfinder magnification, about 0.52x, gives a correspondingly
short effective rangefinder base, under 20mm. This is not really adequate to
focus the 50mm f/1.5 at full aperture and at short distances, though it’s
fine with the 50mm f/2.5. Likewise, although the 75mm f/2.5 and 90mm f/3.5 couple
perfectly adequately, focusing below (say) 3 meters/10 ft is marginal at full
aperture.

This
would appear to be a new golden age for rangefinder users. There are now three
major systems (Leica, Voigtländer, and Zeiss) and two minor (Epson and
Rollei). All use the same cross-compatible lens mount, for which an extensive
and excellent range of lenses is available, and all compete with one another,
albeit at different price points. Who could have imagined this even a decade
ago?
