(Shades) for Pentacon Six Lenses
Three 250mm lenses are available in the Pentacon Six mount:
A round, slightly-conical hood is supplied with this lens. For storage it slides conveniently over the front of the lens, reversed, though I wrap it and the lens separately to prevent damage through rubbing to either component.
250mm Jupiter or Yupiter
The 250mm Jupiter or Yupiter was normally
supplied with the lens hood and metal cap shown here:
Arsenal filter and shade mounted on the lens.
|For storage with the lens illustrated here, the shade is
reversed and screwed into the front of the filter.
The lens cap then screws onto the back of the shade – a
very neat solution.
Strangely, the lens cap, seen on the left in this image,
cannot be screwed into the front of the lens,
but only onto the back of the inverted lens shade, as it has a "female" thread.
|The manufacturers have achieved an inside
mounting thread within the lens shade by making a ring with
the thread on it. During assembly in the factory, the
ring is screwed to the lens shade with four tiny screws,
just visible in the image on the left. The 1980
Yupiter lens that I bought (not new) only had three of the
screws still in place. The empty hole is arrowed in
After a recently international journey, I got the lens out of its case and found that the other three screws had all come out, something that can happen to a lens from any manufacturer in consequence of vibration, especially in an aircraft, I am told. Fortunately, I was able to retrieve the screws from the case and re-assemble the ring onto the lens shade.
These tiny screws are no doubt standard stock items in a camera factory, but it strikes me that they are far too small for this large lens shade on this heavy lens.
What is more, on occasion when the shade is removed from its stored position, the filter may come away too, screwed deep within it and very difficult to access!
It is clear that the shade for this lens needed re-designing, and that is precisely what happened. Here is the new version, on a lens manufactured in 1991.
The lens shade is mounted on the lens during manufacture. It can be slid backwards for storage, and forwards for use. Here it is in the forward position.

|250mm Telear or
To the right: the f/5.6 ARSAT (It may be possible to read the numerals on the lens name ring, which incorrectly state that this is an f/3.5 lens!)
This lens hood has parallel sides, i.e., it is a simple tube, not a section of a cone. One good consequence of this is that the supplied clip-on lens cap will fit equally well on the lens or the end of the hood. This encourages transporting the lens with the hood permanently in place. How many pictures that would have benefitted from use of a lens hood were taken without it, because the time or inclination to fit it were lacking?
The 300mm Sonnar was normally supplied with
the lens hood shown here:
However, earlier versions of this lens were supplied with a much longer lens hood that had a front diameter of 112mm and its own lens cap. Note that this lens hood has a 95mm rear thread, and is mounted via an 86mm-95mm step-up ring, the same ring as supplied for the Carl Zeiss Jena wide angle lens hood discussed above.
As with the 180mm Sonnar, a clip-on lens cap is used here, as the non-marque UV filter has a narrower outer diameter than the CZ product, resulting in the standard cap falling off.
Two 500mm lenses were designed for the Pentacon Six mount:
Here is the 500mm Arsat APO lens with its integrated, retractable lens hood. For more details concerning this lens, see here.
There are some other 500mm lenses that are occasionally supplied with a Pentacon Six mount, although they were not designed for this format. For details, see here (scroll down).
The 600mm mirror lens is not supplied with a shade, and some versions of the lens do not even have a front thread for accepting filters or hoods. For a detailed discussion of this, see the full description of this lens here.
This lens is supplied with the lens hood screwed to the front of the lens. As the complete assembly fits into the supplied box with the hood in place, there is no reason to remove it. The massive lens cap fits onto the front of the hood. For more details of this lens, start here.
|The Zoom lenses
Two zoom lenses in Pentacon Six mount were made by Schneider-Kreuznach:
This lens was supplied with a lens hood mounted on the lens.
Here the lens hood has been removed to reveal its size. It is in fact extremely shallow – no doubt in order to avoid any danger of vignetting at the wide-angle end. The supplied lens cap fits to the end of the lens hood.
The 75-150mm Variogon with the lens hood in place.
The lens hood is attached to the lens via an adapter ring that increases the diameter from 95mm to 100mm, according to my measurement.
This is the lens that was supplied for many years (with a built-in shutter) for a range of Hasselblad cameras.
The lens hood is mounted onto this lens without the need of an adapter ring.
|For storage, the lens hood is reversed and screwed onto the front of the lens. The lens cap is a press fit to the hood in this position or in the using position. This solution is similar to the one adopted by Arsenal for the older (1980) Jupiter 250mm lens that I have.||
