Leica just announced the availability
of the Leica R-Adapter L which finally offers a good alternative to use the
Leica R lenses on the Leica SL as well as the Leica T. Today we learn about another new use for the
Leica R lenses.
More and more film makers
have discovered the creative properties and the high quality of many older
lenses. To allow these optical top
performers to maintain their excellence when subjected to the mechanical
requirements of film production, the Firm of P+S Technik in Munich is offering
a rehousing program where the optical components are transferred to a new lens
barrel.
The optical components of these
older photographic lenses are used in a housing, which allows an optimal
interaction with the motorized focusing and aperture control units when
filming. In addition, P + S Technik has
also launched a program for lenses with floating elements. The diaphragm mechanism of all lenses has also
been improved.

Leica R lenses are now
incorporated in the SL case of P + S with a front diameter of 110 mm. The invention of "Floating
Elements" was a big, important step in the history of optical design. This
technique has been transferred from zoom lenses to fixed focal length lenses to
correct chromatic aberrations during focusing over the entire field of the
focusing range.
In a classic lens design,
the entire optical system is moved back or forth to corerwect focusing at the
image plane. In a floating lens element
system two or more lens elements are moved simultaneously and independently from
each other.

Often these older lenses
are described as being softer and less contrasty than their modern counterparts,
but when compared to most vintage lenses, these examples are sharper and
display noticeably higher contrast levels.
Obviously this is only a
relatively small market, but the very fact that the Leica R lenses are part of
this rehousing program by P+S Technik further underlines the incredible
performance levels these lenses are capable of.
