Re: Is L glass that good? The market for used Carl Zeiss (Contax) and Leica wide angle lenses
was small and prices were reasonable. Then Canon users "discovered"
that these lenses were vastly superior performers to any of the Canon
wide angle lenses.
The result is that the used market has been set on fire, with prices
rising rapidly. Sales of Contax- and Leica R-to-Canon EF adapters
have soared; rather than being one-off specials these are now in
series production in China.
Online forums where pro users discuss equipment (and that obviously
excludes this newsgroup) are packed with details of how to get
non-Canon lenses to work well on Canon EOS cameras, both film and
digital. There are even workarounds for the Canon EOS 5D, whose
mirror is longer than needed for Canon glass but *just* long enough to
clash with some popular off-brand lenses. What a coincidence! It is
almost as though Canon did it deliberately! (Surely not?!?!?!)
Even Pentax SMC Takumar M42 mount lenses are popular on EOS cameras
and the adapters are widely available. That is because several of
them are optically better performers than the latest Canon glass. I
know that at least one adapter to use the optically even better Pentax
K and KA lenses on EOS bodies is also being developed.
So there is huge interest in using non-Canon glass on EOS bodies. You
probably don't hear much about the subject on this newsgroup because
this newsgroup has long been left behind by other online forums.
