Frequently Asked Questions

Anamorphic Rear Adapter
  • 1.1 - When using the rear anamorphic attachment for the cooke zoom lens, would this change all the markings on the focus ring? For example, setting the focus to 10 foot on the lens, would a subject in focus at 10 foot?

    The zoom scale changes: multiply the focal length x2

    The focus scale stays the same if the lens with adapter is properly collimated, so yes, a subject at 10 feet would be sharp with the lens set to 10 feet.

Birdcage
  • 2.1 - Is it possible to use a Sony A7II (or ILCE-7M2) camera with the Birdcage and the BoomBooster. I know it can be used with the A7s, but does it fit the A7II fit or is this camera too big?

    We are working on the new BIRDCAGE A7 II and A7R II.

    THE NEW EDITION OF THE BIRDCAGE A7 II WILL BE AVAILABLE IN SEPTEMBER! The new SONY A7 II SERIES is bigger and fatter.....needs a complete new design. 

    The BoomBooster will be totally compatible between different BIRDCAGE A7 Series.

Evolution 2X Anamorphic Lenses
  • 3.1 - Can you use spherical and anamorphic lens within the same project?

    Absolutely. Most productions usually use spherical lens throughout a project, but you could use an anamorphic lens for a particular wide shot in order to make it look different than the rest. For example, use an anamorphic lens for a dream sequence. Be sure to discuss it with your post production house first.

  • 3.2 - Did you licence the Kowa anamorphic lenses in order to make them?

    We don't make Kowa anamorphic lenses. We designed the Evolution 2X lenses with our own formula, but matching the Kowa anamorphic lenses. We have gone a step further and improved on the mechanics and housing while maintaining the original look.

  • 3.3 - Do you sell the Kowa anamorphic lenses?

    We buy and sell used, selected equipment, but mainly rehouse them and replace broken or damaged elements. However, we do manufacture and sell the next best thing called the Evolution 2X lenses. LINK

  • 3.4 - I've never heard of Kowa anamorphic lenses. What are they?

    Kowa anamorphic primes lenses were produced until the 1970s and four different primes were available: 40mm, 50mm, 75mm, 100mm. They are rare and always in demand which is why we continue to service them. Our new Evolution 2x series of lenses were created in resposce to the demand today.

  • 3.5 - What are Evolution 2X lenses?

    They are anamorphic lenses that are completely new and re-engineered designs of the rare and vintage Kowa anamorphic lenses from the 1970's. They are based on the original optical design with completely new mechanics and sturdy housing and they match the genuine anamorphic look of the originals.

  • 3.6 - What do you mean by 2x?

    The 2x refers to the anamorphic squeeze ratio that the lens is applying to the image. We also offer a 1.5x squeeze ratio in our TECHNOVISION Classic 1.5x lens series.

  • 3.7 - Where are the Evolution 2X series of lenses primarily used?

    They are intended for anamorphic filming but due to their size and light weight, they are also ideal for handheld or camera stabilzed or drone work.

  • 3.8 - Where can I see a demo of one of the new Evolution 2X lenses?

    There are a few places: At a local rental house, at one of our resellers, at a trade show, or by appointment at our Munich office.

  • 3.9 - Why did you add two additional lenses to your Evolution 2X series of lenses and do they also match the original look?

    We discovered through feedback from DOP's that the original focal range was limited, so we engineered two additional focal lengths, a wide-angle 32mm and a telephoto 135mm, which match the geniune look of the original set. 

IMS mounts
  • 4.1 - Are you also working on a Leica M mount for the Arri Amira or Mini?

    The ARRI Amira and Mini cameras will not work with Leica M lenses. The mount interface at these cameras is 24mm. The flange focal distance of Leica M lenses is only 19mm.

  • 4.2 - Can I use the IMS B4 mount together with the FZ adapter ring on a Sony F55 / F5 / F3 ?

    No, mechanically it does not fit the Sony cameras. The IMS B4 mount was designed especially for cameras with IMS interface on camera and a smaller sensor (SI-2K, A-Cam)

  • 4.3 - Do you have a MFT mount for IMS cameras?

    No, the flange focal distance of MFT (Micro 4/3) is almost same as the flange focal distance of our IMS intermediate flange, so we cannot offer this adapter combination.

  • 4.4 - Do you offer a Sony FZ to Sony E adapter?

    No.

  • 4.5 - Do you offer a Sony-e to Sony-Fz mount adapter?

    No. Our R&D department evaluated this adapter combination and found it is techinically impossible to design this mount adapter.

Lens Rehousing in general
  • 5.1 - How about the coating ?

    1) we check the coating at receipt of the lenses and recommendations will be given

    2) uncoating is possible on request

  • 5.2 - How should I understand your lens service report / recommendation?

    Generally there is a great difference in expectations between an owner of a lens using it himself or a lens available from a rental house. That is what we've learned.

    Report explanation:

    slightly dirty means you can see dirt under good test condition, but the influence of the image will be very little

    dirty means you can see dirt easily and you may have more flair light in the lens and on the image

    oil means oil has gone from the iris mechanic onto the glass which causes for sure more flares. The old oil got dry and made the iris stiff, service is strongly recommended

  • 5.3 - What is the warranty on the rehousing ?

    12 months warratny on mechanical parts by P+S Technik

  • 5.4 - Why are two different minimum aperture values engraved on the rehoused lens?

    On our rehousings we engrave the T- or f/stop value of the original lens as a reference on the bottom (if looked at the lens from the camera) of the aperture ring.

    We re-measure the aperture stops and engrave according to those new effective values. T-stops are engraved with a line and numbers, additional short lines indicate the 1/3 of a stop in between. Deviations from an original T-stop value result from aging of glass and especially from the yellowing of lens elements.

  • 5.5 - Why can the aperture ring move over and further than the smallest/largest T-stop marking on the aperture ring?

    If the aperture ring has overstroke without marking, the aperture can be opened or closed further than the last marking but less than a 1/3 of a stop.

    T-stops are engraved with a line and numbers, additional short lines indicate the 1/3 of a stop in between. Only the last full T-stop do the shematics (https://de.wikipedia.org/wiki/Blendenreihe_(Optik))

  • 5.6 - Will the lenses be colour matched after rehousing or lens service ?

    No, colour matching of the lenses is not possible! 

    We are talking about vintage lenses here and each lens got it's own character over time.

  • 5.7 - Will the serial numbers of the lenses stay the same after the rehousing?

    Yes.

Lens Rehousing of Bausch & Lomb Super Baltars
  • 6.1 - Are the lenses checked for fungus and thoroughly cleaned with fungi-stopping baths before rehousing?

    Here what we have measured as MoD from sensor plane to object:

    18mm: 0,13m

    25mm: 0,18m

    32mm: 0,23m

    40mm: 0,33m

    50mm: 0,4m

    75mm: 0,53m

    100mm: < 0,80m

  • 7.12 - Why are some Cooke Speed Panchro 75mm lenses project a very yellowish picture ?

    The yellow color of the optics visible in particular at most 75 mm Cooke Ser. II / III lenses has its cause in glass type used back then. The glass type includes a share of Thorium and also emits radioactive. This (weak) radiation is detectable with the Geiger counter.

    We have dismantled the optics to identify the corresponding glasses. These glasses are also yellow. It is the front lens and a further lens.

    The type of glass with the Thorium share has historically been replaced by an equivalent other glass type. Whether that was made by the company Cooke in the course of production is not known by us. But we've had lenses with newer serial numbers that already have multi-coating and are not yellow.

  • 7.13 - Will my Panchros have a marco / close focus after the rehousing ?

    Yes, the macro / close focus is included in the rehousing.

    On request rehousing can be done without macro ability.

LensChecker portable projector
  • 10.1 - Can the lens checker with case be used as a carry-on item for travel?

    Yes. The size conforms. However, although it has been designed like a suitcase, you should never pull it along a bumpy surface. The vibrations could affect the integrity of the unit.

  • 10.2 - Does it only work with PL lenses?

    No, it comes standard with a PL mount, but you can add a variety of optional mounts including: BNC-R, C-mount, Canon EF, Canon FD, Leica R, Leica M, Nikon F, Panavision, Sony E-mount*. This is possible because the unit also comes standard with the IMS - Interchangeable Mount System, which is a simple "plug and play" mount. *The Sony E-mount is not plug and play and requires a separate mount.

  • 10.3 - I like this unit and would be interested in buying it. Is there an educational course?

    We offer some education in-house and we'd be happy to get you started with your purchase. It's very easy to operate and comes with a user manual.

  • 10.4 - Is there an international unit for sale?

    It's not necessary. It is an international unit with built-in transformer that runs on 12 volt, so all you need is to attach one of the four supplied adaptor plugs into your electrical outlet. The lens checker can also be battery powered.

Lockport
  • 11.1 - Can a LockPort fit different camera models not available on the list ?

    The LockPorts are designed to fit exactly dedicated camera shapes offering maximum strength to mount the HDMI adapters without any play.

  • 11.2 - Can I change the camera battery without dismounting the LockPorts?

    -          ­Yes! LockPort design knows how important a battery change in the middle

    of a shooting will be!

  • 11.3 - Can I change the tilt angle during a shot?

    The system is designed to work with fixed tilt angles. With some experience you
    might also be able to tilt in a shot, but this needs some experience. We've heard
    about DoPs doing this.

  • 11.4 - Can I still use the audio connectors on my camera when the LockPort DUAL is mounted?

    Yes, the audio connectors are accessible when the LockPort DUAL is mounted to the camera.

  • 11.5 - Can I still use the power input socket of the BM Pocket camera when the Lockport Pocket is attached to the camera ?

    The input power socket of the BM Pocket is a fat connector and maybe need to be cut a little on the side to go thru....

    Other customers, on our suggestion, changed the fat power connector with a more professional and compact one to have more room to go in...

    Space and room in the pocket are really tight...

  • 11.6 - Can I upgrade my exisiting LockPort to LockPort DUAL?

    No, the older LockPort models cannot be upgraded to LockPort DUAL.

  • 11.7 - Can I use my LockPort 5 or 7 without a RedRock Micro DSLR baseplate ?

    The LockPort 5 or 7 are designed to work only like an upgrade of the top plate of the RedRock Micro DSLR baseplate.

  • 11.8 - Can I use the LockPort (all models) with my camera battery grip ?

    The LockPort cannot work with a battery grip on any camera

  • 11.9 - Does the LockPort work properly with HDMI external recorders?

    LockPorts adapters and cables work perfectly with external recorders.

  • 11.10 - I bought a Lockport universal for my Canon EOS 5D MK II. Can I use it on a 5D MK 3?

    An UPGRADE KIT for the LPUFK is not available, because it needs a new baseplate and a smaller HDMI connector. The Cannon 5D MK3 is smaller than the old MK2.

    Anyway we can supply all the parts your customer needs in a SPECIAL UPGRADE ORDER for Euro 69,00 list price (P+S price 48,30).

  • 11.11 - Is the Lockport compatible with a vertical or battery handgrip for my DSLR camera?

    The Lockport was originally developped for video recording with DSLR cameras and direct HDMI output.

    So the Lockport concept is not compatible with a vertical or battery handgrip.

    Nethertheless the battery compartment is always accessible with the Lockport or Birdcage port protection attached to your camera.

  • 11.12 - Is the SKATER Mini only meant for table top work?

    The design comes from a table top background. But more and more the SKATER
    Mini is also being used in feature and documentary work, especially on locations
    which are hard to reach. If you have to walk up five flights of stairs it might be
    easier to just take the SKATER, two apple boxes and a board than to bring a dolly
    and tracks up there.

  • 11.13 - Lockport GH4: Why didn't you reverse the hdmi plug in (from the front, beside the lense)? The way you did it makes it impossible to rotate the gh4 screen?

    We tested longly also the FRONT OUTPUT and there is still a interference with the swivel LCD monitor (and still cannot rotate).

    The LockPort GH4 was designed for shooters looking for a 4K output (asking of rear output) for external 4K recorders and using electronic viewfinders.

    I can understand your point of view...but with a swivel monitor and a side HDMI port output - this is not an ideal camera layout.

  • 11.14 - My RedRock Micro DSLR baseplate has monilitic design, can I still mount the LockPort 5 ?

    The early generation of RRM DSLR baseplates did not had the choice to disassemble the top plate which can be now replaced by our dedicated LockPort solution.

  • 11.15 - What happens with a LockPort mounted on my camera without the cable connected ?

    -          ­With a LockPort mounted and no cable connected, the camera  works exactly like when is without it.  Full functionality!

  • 11.16 - What’s the difference between normal LockPorts and the “Z” edition ?

    LockPort “Z” series are designed for Zacuto Z-Finder users! It has as a special flat rear design to offer full mounting compability with the Z-Finder. Also you will find a small locking plate in the box to add strength to the Z-Finder mount.

  • 11.17 - When using the Lockport Pocket with my Blackmagic Pocket camera, how can I power the camera? Is the battery case or the power input port accessible?

    The battery case is accessible while the LockPort Pocket is attached. The 12V power port is blocked by the LockPort HDMI adapter.

  • 11.18 - Where can I find the LockPort 5/LockPort 7 mounting instructions ?

    In the LockPort section of our LockCircle website you can see a 9 step banner showing how to mount the LockPort 5 / 7 step by step!

PrimeCircle lenses
  • 12.1 - Could you tell if those Prime Circle lenses cover full frame 24x36mm?

    Yes, they cover full frame 24x36mm.

    All PrimeCircle lenses are based on high class Carl Zeiss still photography lenses.

PS-Zoom 18-35
  • 13.1 - Does the autofocus via the ef mount still work?

    No, the PS-Zoom 18-35 is a completely mechanical zoom lens.

  • 13.2 - Does the PS-Zoom 18-35 cover the 6K RED Dragon sensor?

    Yes, but with a limited zoom range. The PS-Zoom 18-35 covers 6K RED Dragon from focal length 21mm.

  • 13.3 - Is a Panavision lens mount available for the PS-Zoom lenses?

    No.

  • 13.4 - Is the lens your design or a rehoused Sigma 18-35mm?

    Yes, the PS-Zoom 18-35 is based on the Sigma 18-35, the mechanical design original by P+S Technik.
    We designed a high-quality, reliable housing with a professional cam-driven focus mechanism around this fast lens.

Skater Mini
  • 14.1 - Can I change the tilt angle during a shot?

    The system is designed to work with fixed tilt angles. With some experience you
    might also be able to tilt in a shot, but this needs some experience. We've heard
    about DoPs doing this.

  • 14.2 - Can you tell me the torque rating on SKATER Motor?

    The torque rating of the SKATER motor is 17 mNm.

  • 14.3 - Does the SKATER Mini replace a dolly?

    No, the idea is to use it whenever it is faster and more efficient. In most
    productions the SKATER Mini is required as well as a dolly and will be used for a
    few shots only. For fast removal of your camera head from a dolly, crane or tripod
    we have integrated a dovetail into the SKATER Mini, so you can easily make
    those changes without losing time on changing the sliding plates.

  • 14.4 - How precise is the repeatabilty of the SKATER Mini?

    If all wheel directions are precisely aligned, the SKATER is very precise. We
    recommend to always use calculated values for all scales, as they are much more
    accurate. Use the supplied rotation table or, even better, get a free download of
    the Rotation Calculator (available in Palm versions or as an Excel file,
    www.pstechnik.de). It will give you proper results.
    In any case it can be useful to mark the start and end point of a move with a
    marker. If there is a slight offset after a couple of takes, you can still re-position the
    SKATER according to the marks. Those marks will also help the camera assistent
    doing the focussing

  • 14.5 - Is the SKATER Mini only meant for table top work?

    The design comes from a table top background. But more and more the SKATER
    Mini is also being used in feature and documentary work, especially on locations
    which are hard to reach. If you have to walk up five flights of stairs it might be
    easier to just take the SKATER, two apple boxes and a board than to bring a dolly
    and tracks up there.

  • 14.6 - The object I'm filming is too high or too low, how can I adjust the lens height?

    One way is to change the vertical position of the object or the tracking surface. If
    the lens should be just a bit higher, change to the +/-30° rocker, which will
    increase camera height about 2 cm or 0.8 inch. If you need to go a bit lower, loose
    the sliding plate and the integrated dovetail and mount the camera directly onto
    the rocker.
    Another elegant way is the use of a straight borescope (see above) as it allows
    you to adjust a lens height by changing the tilt angle of a camera.

  • 14.7 - What kind of surface do I need?

    Just about any one will do. Make sure the board, platform, table or floor has a
    plain surface. If you have a solid surface but it has dents, just place a thin plain
    panel on top. Sometimes it’s only necessary to track a couple of inches to achieve
    the desired shot, so often the tracking surface doesn’t have to be extremly big.
    Also keep in mind that the wider your shot is, the less critical is the surface. If you
    are on a wide lens you might even get away with small dents or a slight
    uneveness on the surface.

  • 14.8 - Where can I find the Skater Mini rotation calculator application?

    Although the Skater Mini rotation calculator is no longer available as an application for smartphones, you still have the possibility to use the rotation calculator as an Excel sheet. You'll find it in the download section of our homepage (https://www.pstechnik.de/support/downloads/). The excel sheet is called "Skater_RotationCalculator1.01.xls".

Skater Scope
  • 15.1 - Can I use the SKATER Scope with anamorphic lenses?

    Yes.

    The anamorphic format is produced by the anamorphic front lens and the SKATER Scope basically "only" transport to image to the sensor. 

    Please keep in mind that some anamorphic lenses are heavy and might need additional support when used on the SKATER Scope.

  • 15.2 - What is the depth of field produced by the SKATER Scope?

    The depth of field in the image depends on the lens attached to the front of the SKATER Scope and the sensor size.

  • 15.3 - What is the lens speed of the SKATER Scope?

    The measured max. speed is 5.6.

    The aperture setting of the lens in front of the scope does only influence the light going through the system once the aperture settting is > 5.6

T-Rex Superscope
  • 16.1 - Dimensions of the T-Rex Superscope?

    The length of the T-Rex is

    from mount (camera side) to the rotation joint approx. 610mm

    from the rotation joint to the lens mount approx. 110mm

TECHNOVISION 1.5X Anamorphic Lens Series
  • 17.1 - How accurate are the focus markings on this lens and does it change depending on Super35mm or FullFrame?

    The focus marks are custom tailored to each lens and are very accurate. The accuracy of the focus markings are not affected whether you are shooting Super35mm or FullFrame (36 x 24mm).

  • 17.2 - Is a Panavision lens mount available for the TECHNOVISION Classic 1.5x lenses?

    No, only PL-mount.

  • 17.3 - What do you mean by 1.5x with this lens?

    The 1.5x refers to the anamorphic squeeze ratio and this factor is ideal for Full Frame and larger Formats. We also offer an 2x squeeze factor in our Evolution 2x lens series.

  • 17.4 - What does the CLASSIC mean?

    We use the term Classic, which refers to the classic anamorphic design principle of having a front anamorphic cylindrical element.

  • 17.5 - When someone says your lens is futureproof, what do you mean?

    In terms of the market for ever larger camera sensors, the TECHNOVISION Classic 1.5x lens series has a relatively large image circle meaning it will cover most full frame camera sensors throughout most of its focal range. In terms of the most common sensor used today - Super35mm - the TECHNOVISION Classic 1.5x lens easily covers the sensor at all focal ranges with no vignetting - and is designed for use with emerging larger sensors.

  • 17.6 - Which diopters and extenders can I use when working with TECHNOVISION Classic 1.5X Anamorphics?

    When shooting with TECHNOVISION Classic 1.5X Anamorphics we recommend using ARRI/Zeiss Master Diopters or Schneider Diopters to work at a closer focus distance. If you want to extend the original focal length we recommend using an extender like the PLx2 VV from IB/E OPTICS.

Xpander Lens
  • 19.1 - Could this Xpander Lens 21% give you the ability to use the Canon Super16 8-64 zoom on a red in 4k?

    No, the current version of the Xpander Lens is designed for the use with 35mm and better Super35 format cine lenses.

  • 19.2 - What is the difference between version 1.15 and 1.21 ?

    Basically the expansion factor and the resulting light loss is the difference.

    Version 1,15
    Image expansion factor: 15 % larger (nominal)
    Focal Length: X 1.15
    Light loss: 1/3 to ½ stop

    Version 1,21
    Image expansion factor: 21 % larger (nominal)
    Focal length 1.21
    Light Loss 1/2 to 2/3 stop
