Leica rangefinder cameras used
to be relatively awkward for close-up photography. The rangefinder focusing is not well suited
for this task by itself and always requires special close-up accessories. Over
the years Leica has produced a relatively large variety of them, the most
versatile of which arguablt were the Visoflex housings which essentially
converted the rangefinder camera to a single lens relflex (SLR) camera. But they were bulky and added a lot of
weight.
It wasn’t until the
introduction of the Leica M 240 that esy close-up photography could be done
with a Leica rangefinder camera. The
live view of the CMOS sensor allowed real time observation of the image, either
on the camera screen or with the electronic viewfinder ot electronic
Visoflex. Of course even here some
accessories are needed to overcome the limited close focus abilities of the
lenses.
In order to focus any lens
closer than what the standard focusing mount of the lens allows, it has to be
mover further from the film or sensor plane.
The simplest means to do so is with extension tubes which usually come
in different lengths to allow for a variety of minimum focusing distances.
Novoflex offers a rather
versatrile extension tube system with their LEM/VIS II extension tube set for
the Leica M. It greatly enhances the
versatility of the camera. The entire
set has the same length as the Leitz Visoflex II and III. Subsequently, it can eliminate the use of the
Visoflex units when using any of the so-called Visoflex lenses on the Leica
M. Instead either live view or the
auxiliary electronic Visoflex finder can be used for viewing and focusing. In addition, the extension tubes in various
combinations can be used to achieve close focusing with any Leica lens. The set consists of five separate sections,
the lens mount, the camera mount and three extension rings that can be used in
various combinations to achieve a variety of close-up ranges with Leica and
other M mount lenses.
For even greater versatility this extension tube set can be used in conjunction with the Leica Bellows II. This bellows was meant to be used with the Visoflex I or II. It allowed infinity focus with any of the so called Leica Visoflex lenses, but offered very close focusing without the need for any other accessories. Since the Novoflex LEM/VIS II set is designed to replace the Visoflex housing, the use of the Leica Bellows II offers the same versatility without the need of the Visoflex. Using standard Leica lenses will offer a great variety of close-up ranges, making the Novoflex a LEM/VIS II a welcome addition to the Leica M system of anyone interested in the world of close-up photography.
For example, the Leitz Telyt
560mm f/6.8 will focus to infinity when mounted on the Visoflex I or II. Replacing either Visoflex with the Novoflex LEM/VIS
II extension tube set will allow for the same use on the Leica M240. This would also be the case in the above setup
which added the Leica Bellows II for a much greater close focusing range.
This is a photograph taken with the above system. Replacing the Visoflex II with the
Novoflex extension tube set would render exactly the same result.

How does Novoflex compare to Leica in terms of quality?
ReplyDeleteVery favorable. Of all the aftermarket accessories on the market available for Leica, Novoflex is by far the best. It's another case of "you get what you pay for."
DeleteWhat if you use this set with the Visoflex in place?
ReplyDeleteYou would end up with the ability to focus closer than normal with any of the Visoflex lenses and greater close up capabilities with all the other Leica M mount lenses. With standard Leica M lenses, the Visoflex II or III alone would allow you to focus as close as with the complete Novoflex set. Adding the Novoflex set in its various combinations subsequently would allow you to focus substantially closer.
DeleteWouldn't a bellows from Leica or Novoflex be more practical for its ability of infinitely variable extensions alone? It would eliminate the necessity of plumbing around with the different extension tubes.
ReplyDeleteYou are basically correct. However, the bellows are definitely bulkier and less portable that the extension tube set.
DeleteWouldn't a lens made for close up photography have rendered better results than using a 560mm?
ReplyDeleteOf course. Any lens is optimized for its primary use, thus the 560 Telyt is optimized for use at relatively long distances. However, in this instance I wasn't about to get any closer to the hornets than necessary. As it was, even at the approximately 20 foot distance it wasn't exactly a comfortable working environment. Those hornets were very aggressive.
DeleteIt would have never occurred to me to do close up photography with such a long lens.
ReplyDeleteMe neither. I guess this is an example of necessity being the mother of invention.
DeleteI understand that this set is made for use on the Leica M, but would it also work on the Leica M-AF? ;-)
ReplyDeleteDefinitely. That would be the only camera that offers autofocus with extension tubes. :)
DeleteWhat's a Leica M-AF?
DeleteThe article on this blog, "SENSATIONAL AUTOFOCUS LEICA M-AF," has a full description of the camera.
DeleteInteresting. Any idea at all when it might be available?
DeletePlease allow me to refer you to the publishing date of the Leica M-AF article.
DeleteI should have known.
