Pentacon Six System
Sport-Reflectar 1000mm f/8
mirror lens for
the Pentacon Six
The 1000mm Sport Reflectar, We
note the strong, metal front lens cap!
Pont states (p. 76) that there is only
one serial number known for this lens. Here is a
second one! It has a WE camera adapter mount,
which means that, amongst the vast number of cameras for
which Kilfitt produced mounts, there is one for the
Pentacon Six: the WESI mount. According to Pont
(p. 77), other mounts included:
WEHA – Hasselblad 2000
FUEPE – Pentax 67
WEMA – Mamiya 645
There are of course also
numerous mounts for 35mm cameras, and if a lens has
the WESI mount for the Pentacon Six / Praktisix,
converters from this mount to numerous other cameras,
including the newest mirrorless digital cameras, are
readily available, both new and second-hand.
Zoomar/Kilfitt Sport-Reflectar compared with the
1000mm Carl Zeiss Jena Spiegelobjektiv
Let us first compare tihs Kilfitt lens
with the Carl Zeiss Jena 1000mm mirror lens. The
following photograph and caption is from the article by
Carsten Bobsin in Photo Deal Nr. 76, I/2012 (Januar
Februar März) p. 25. Below the image we translate
5.6/1000 Mirror lens one speaks more of
putting the camera onto the lens rather than
the other way round. So that the 14 kg
heavy lens does not become a piece of real
estate property that cannot be moved, it
is supplied in a large wooden case with two
At 6.6 kg, the Zoomar Reflectar 8/1000 that
was presented to the public in 1970 is
substantially lighter and provides internal
As well as the very-visible difference in
size, we also note that the Kilfitt/Zoomar lens has a
carrying handle, which in practice is extremely
useful. At 14kg, getting the Carl Zeiss Jena lens
onto a tripod is not easy and requires a good
technique. At less than half the weight – and with
the carrying handle – the Kilfitt Sport Reflectar is
easy to handle. Of course, this 1000mm Zoomar has
a maximum aperture of f/8, one stop “slower” (smaller)
than the f/5.6 of the Carl Zeiss Jena 1000mm lens.
However, when shooting pictures of the moon (see here), we found that f/5.6
was almost larger than we needed!
We would also expect slightly more depth of field at f/8
than at f/5.6, not a negligible point with such a long
lens. After all, how often do we take pictures
with an aperture of f/5.6? It is not normally the
aperture that is required to get the best image from a
The 1000mm Zoomar Sport-Reflectar
compared with the 500mm Kilfitt/Zoomar
To give a further indication of the size
of this Kilfitt lens, let us compare it with the Kilfitt
500mm Sport Reflectar, which is reported on here on this website.
Here we can see the focussing lever
of the 500mm mirror lens.
Both of these
lenses have inner focussing, which means that
the length of the lens does not change as one
focusses, in contrast with the Carl Zeiss Jena
Spiegelobjektiv, which has bellows at the back
of the lens to provide focus. Both Zoomar
lenses also have a focussing lever, while the
Zeiss lens has a focussing wheel. See
details of the back of the Zeiss lens here.
the 1000mm Zoomar Sport-Reflectar on a tripod
The 1000mm Zoomar
has a base that is long, wide and strong and is
provided with two tripod sockets, one for ¼" and the
other for 3/8".
I am here using one of my
Arca-Swiss-compatible tripod-mounting plates,
on which more details can be seen here. I
found that if I just used one of the sockets,
the lens could swing on the mounting plate, so
I had a second hole drilled in the plate at
the right distance, so that both sockets on
the lens could be used. As each mounting
bolt has a different diameter, I have two
Allen keys, one for each bolt, visible on the
left in this photograph.
We can here also see the focussing
lever for the lens, which has here been
mounted on a Praktisix camera.
To the right, the lens is mounted on
the Arca-Swiss B1-G ball head, which is on the
Berlebach tripod. I think that in fact
the Benro tripod described here would
have no difficulty supporting this lens
Here one of the
latest Pentacon Sixes, with the added mirror
pre-release mechanism (see here),
has been mounted on the lens. The lens
focussing lever is pointing down at about
50º. The knob on the end of the lever
enables focus to be locked at any point.
(The horizontal knob that is further forward is
part of the locking mechanism on the tripod ball
for the user
photographer’s-eye-view of the lens (minus
camera), we can see further features.
Here the lens has a WESI mount for the
Pentacon Six. Between this mount and the
back of the lens we can see the square corners of
something. This is the filter holder,
for – in true Kilfitt style! – this lens can take
gelatine filters. This is potentially much
more flexible than the filter system on the Carl
Zeiss Jena 1000mm mirror lens, which admittedly
had built-in filters, although these had been
designed in the 1950s at a time when much
photography was in black and white, so the filters
available were UV, ND,
Yellow, Orange, Light Red, Dark Red, the colour
filters all having been chosen to darken the sky
and enhance clouds to varying degrees with
Below the lens we can see the
aluminium (US: aluminum) tripod plate
with its dovetail base.
At the “five o’clock” position we
can clearly see the focussing lever.
If we look at the top of
the handle, we may notice at its front a
circular pointed protrusion in chome
colour and at the back of the handle a
similar raised piece of metal, this time
with a V-shaped notch cut into it.
Line up the raised point at the front of
the handle with the notch at its back, and
you will see exactly where the lens is
pointing! We have here taken this
picture from slightly higher than where
our eye would be in practice, to make the
raised point and the notch easier to see.
With very long lenses, it can
sometimes be very difficult to line up the
lens and even to find the intended
subject, and this makes the task much
In the image to the right we can
see the notch on the handle just below the
chimneys of the house in the distance,
while the raised point at the front of the
handle is lined up with the
chimneys. Once we have reached this
point, we can put our eye to the camera
viewfinder while making fine adjustments
to the angle of the tripod head.
Because of the Covid pandemic
restrictions and the onset of winter in the northern
hemisphere, it is likely to be several months before we
are able to publish the results of tests with this
lens. As always, we will notify visitors via the upgrades page.
