Leica M with Canon Lens

That didn’t change until a
few T-4 mounts appeared in the Leica R mount from Soligor and Vivitar and a bit
later from Tamron with their interchangeable camera mount Adaptall lenses. Most of those all but disappeared from the
market, initially because sales of those mounts were too low to justify further
manufacture and later, when interchangeable camera mount lenses were no longer
manufactured. Today aftermarket lens
manufacturers concentrate on the main camera manufacturers like Nikon and
Canon.
Now that the Leica M is a
valid alternative for the R lenses, and since several manufacturers, including
Novoflex, are making adapters to use lenses from other manufacturers on a
variety of cameras, it is possible to use these lenses also on the Leica
M. That offers a huge choice of
different lenses never before available for the Leica.

But does it make sense to
equip a Leica with a lens from another manufacturer? After all, one of the main reasons for owning
a Leica is the quality and performance of their lenses. I basically agree with that, however, I can
also see that in some instances a lens from another manufacturer might be a
valid choice, especially if we enter cost into the equation. For instance, Besides the Leica 14-50 f/2.8-3.5
Vario Elmarit on my Leica Digilux 3, I also use a 55mm f/3.5 and a 105mm f/4
Micro Nikkor made by Nikon as well as a 200mm f/3.8 and a 400mm f/5.6 Noflexar
made by Novoflex on that camera.
Especially the two Novoflex lenses have proven to be very much equal to
their Leica counterparts as have the two Nikon lenses shown to be excellent
performing lenses.

This brings up the question, which
of these lenses do make sense to put on a Leica camera, especially the Leica M? Price should definitely part of this
consideration. While some large manufacturers
can offer high quality lenses at lower prices, simply because of their high
sales volume, nobody is able to perform any miracles. If the price is too good to be true, it is a
safe assumption that this price is the result of considerable cost cutting
measures.
A manufacturer has quite a
number of means to arrive at lower manufacturing costs. Aspherical lens elements are a good
example. The most costly approach to
making such lens elements is to grind them from a lens blank. This is by far the most costly approach, but
also renders the best quality lens elements to assure the highest possible performance. Another approach which, for instance, is used
by Nikon is to make high precision molds and then mold the softened glass into its
final, aspherical shape. This method
definitely lends itself to larger quantity, mass production. The least expensive approach to aspherical
element production, as used by many of the aftermarket manufacturers, is to
make a standard, spherical element and then add a thin, aspherical surface
section made of acrylic to it. These
acrylic add-ons are also molded. This saves
a lot of cost, but it also is a considerable compromise. This process was initially developed by Zeiss
in Germany. It was, however, rejected
because it could not assure the performance parameters set by Zeiss for their
lenses. The reason is that acrylics are
made of rather large molecules. Due to
their size, they actually scatter the light when it transmits which adversely
affects the performance of the lens.
With other words, not all aspherical elements are created equal. There are a huge number of other cost saving
measures that are being used, all of which ultimately lower the overall performance
potential of the lens.
I came across two of the
worst examples of this a while ago when I was still dabbling in repairing cameras
and lenses for my own use. I was asked
to look at an aftermarket lens made by a well-known manufacturer. The lens did not focus to infinity, even
though there were no outward signs of abuse or that otherwise anything was
wrong. I had no choice than to partially
disassemble the lens. Since not all SLR
and DSLR cameras have the same lens to film plane distance, this has to be
taken into consideration when making an aftermarket lens. Rather than making the lens specifically with
the appropriate measurements, a general lens to film plane distance is
used. Then the rear of the lens has a
threaded section which allows the lens to film plane distance to be changed to accommodate
different cameras. After adjusting the
lens via this threaded section to assure proper infinity focus, these threads
then have to be locked in place. This is
usually done with some set screws.
However, this manufacturer apparently decided that additional costs
could be saved by eliminating the set screws and to use a piece of tape
instead. I am not exaggerating; they
used a thick piece of tape around the entire threaded infinity adjustment. The problem with the lens was that the tape
had partially lost contact which had allowed the adjustment to change.
A while later I had a similar
problem with a video zoom lens from the same maker. This was by no means a cheap lens, it sold
for almost $2,100. Video lenses
routinely come with an infinity adjustment to accommodate different video and
motion picture cameras. Remembering the
problem with the other lens, I quickly concentrated on the infinity adjustment
of this lens. My suspicion was
confirmed. Even this relatively
expensive lens used a piece of tape to “secure” proper infinity focus.
I am not saying that all
aftermarket lenses are made with such extreme cost saving measures, what I am
saying is ‘buyer beware’! The low price
has to be arrived at by some means.
My general advice is to equip
your cameras with lenses made by the camera manufacturer. That way there is the general assurance of
the best possible performance. With
other words, put Leica lenses on a Leica to get the most out of your
investment.

But there are valid
alternatives for the Leica. Some of the
older Nikon and Canon screw mount lenses are still performing quite well, but
just as the older Leica screw mount lenses, they don’t measure up to the
current line of Leica lenses.
More modern alternatives are
offered by Voigtländer and Zeiss. Their
M mount lenses have proven to be excellent performers, relatively close to
their Leica equivalents and considering their cost advantage, they do present a
valid alternative. Other choices exist
from Minolta, the older Leitz-Minolta CL lenses, from Konika, Rollei-Cosina and
SLR Magic.

On the Leica R side, adapters
allow the use of Canon, Nikon and a great variety of other lenses. These would need to be adapted to the Leica R
mount which then allows their use on the Leica M with the Leica R adapter or
with a direct four thirds adapter on the Leica Digilaux 3.
Leica is not at all anymore
as isolated as they used to be in the past.
The camera offers a huge selection of lenses from various manufacturers,
and some of them are very good choices indeed.
What is the pistol grip on the Novoflewx lenses for?
ReplyDeleteIt is part of the Novoflex follow focus system. Prior to autofocus, this was the fastest way of focusing a lens. This was achieved by squeezing the pistol grip. Doing so would shorten the lens extension to the infinity position. Releasing the tension on the grip would allow the lens to focus closer. After some getting used to, this is still a very fast means to focus a lens.
ReplyDeleteI use the Novoflex lenses in conjunction with a mono pod and a shoulder stock. This allows the lens to be held quite steady. Another advantage of the follow focus system is that it has no adverse affect on the ability to hold the lens steady.
Are the Novoflex lenses available for other cameras?
ReplyDeleteNovoflex discontinued the manufacture of their lenses, however, they are readily available on the used market, often at very attractive prices. The lenses were designed to incorporate an interchangeable camera mount system, many of which are still available from Novoflex. These, of course, are also available used. They were made for a huge variety of different cameras. Thus it should be possible to mount Novoflex lenses onto just about any camera. In addition, Novoflex also makes a large variety of adapters, to allow different lenses to be used on different cameras. For instance, they make adapters to use Canon, Nikon and many other lenses on the Leica R cameras, just as they make adapters to use Canon lenses on Nikon cameras or Nikon lenses on Canon cameras etc.
