  1. I've ordered two different rubber rings in hopes that one of them will fit snugly around the lens and hold it firmly in the helicoid. I also ordered some PVC pipe tape, some pipe thread sealant tape, and some shrink tubing...between those three I should be able to secure the helicoid to the anamorphic body. Once the orders arrive I'll put it all together and - if successful - post the results back here. I'm taking a few pictures as I go, hopefully they'll help other folks who want to try this mod. Also, based on the conversation here, my curiosity was piqued about adding wide angle adapters
  2. Rich, sorry to keep pestering you...did you use anything else from the front assembly? The part I outlined above sort of looks like the part from your photo below that I've highlighted. Or is that the rubber o-ring you used: I'm trying to determine what I need for securing the element to the helicoid because there is a lot of open space. Also, by your pictures it looks like you used something like electrician's tape for securing the helicoid to the anamorphic section. Is that correct?
  3. I have banged this sucker up and down with the mallet, including using a dowel to tap the outer metal diameter between the glass and the rim on the back side of the housing. Excessive force with the lens tool has cause me to slip twice. Glass is unharmed, but the surrounding metal now has some scrapes & one of the lens tool blades has deformed slightly. This thing won't unscrew....I'm getting pretty disheartened about the whole thing. What about heat? Is it possible to heat it up in distilled water, to get everything to expand & loosen a little, without causing damage to glass/coat
  4. I think I'm having a similar problem to Tito. I was able to unscrew the front section easily. But I'm unable to unscrew the retaining ring/front element with a lens tool. I rapped all around the rim with a rubber handle repeatedly. I also used a syringe to apply the smallest amount of lubricant around the seam where the retaining ring meets the outer housing (yellow arrow) . Nothing will budge. I don't want to apply too much force to the lens tool for fear of slipping and scratching the glass. Perhaps there's some kind of adhesive or glue that was used during manufacture to lock the fro
  5. Thanks for the info Rich! Just got my helicoid in the mail today. Do you recall what kind (diameter, thickness) of o-ring you used to seat the B&H front element?
  6. Nobody uses cd's anymore.
  7. It is. More info here!
  8. Cool, great article! I definitely want to get a WS13 if I can ever find one
  9. Hi Ricardo and welcome! I am also a relative newcomer and have found a huge amount of info on this site, and people here are great at sharing their experiences. You can take a look at the Anamorphic Lens-o-pedia, which is an aggregation of details about various adapters. Also consider the Anamorphic Shooter's Guide. Tito Ferradans has put together some fantastic info here too. All have adapters have advantages and disadvantages. Anamorphic lenses with more in the 'plus' column and less in the 'minus' column are usually more elusive & expensive. A full frame camera like the NX1 will re
  10. Well, if you had waited more than a couple days, I would have my paycheck, and I would have bought it out from under you But there's no use in getting a 2nd B&H unit until I know I can do the mod on the 1st one. As soon as I get that paycheck I'll be ordering a helicoid of eBay (add a couple weeks for shipment from China) and I should be ready to startmodding in mid August. I'll definitely post back to the forum with the results!
  11. I'd jump on this if I had the funds handy, someone else might want to snap up this B&H Projection Lens for $84: http://www.ebay.com/itm/BELL-HOWELL-2-INCH-F-1-4-ANAMORPHIC-PROJECTION-LENS-DESIGN-921-/131564846539?hash=item1ea1e03dcb
  12. Awesome, thank you Rich (and Nick), this is super helpful !!!
  13. By the way, I have been told by a B&H user that the thread on the rear assembly of this projection lens is a Series 7 thread. I will try to confirm as soon as I have money to start buying some parts...
  14. Hi Rich - Thank you for your response!!! This certainly seems like a more affordable solution than finding a machinist to fabricate a new front element. I made the following diagram to make sure I understand the process: Transfer the glass from the B&H front element to a suitable helicoid (using step/filter rings as needed).The helicoid with the B&H glass then replaces the old front element and is joined to the rear assembly.The old front element is not needed and can be stored in case it's ever required again.Is this correct? If so: Which kind/brand of helicoid did you use (or wou
  15. Inspired by QuickHitRecord's excellent post, and this post here, I just acquired a Bell & Howell anamorphic projection lens like this one in very good condition. Does anyone out there own/use this lens? If so, which taking lenses do you find work best? Are you able to zoom through? I'm hoping to find details on how to modify to the front element to reduce the focus throw, and really any details to get the most out of this lens. Any pointers are greatly appreciated! If I can collect enough info to make modifications safely, I'd like to document the process and post it back to the foru
  16. Will do! I know a guy who casts brass in the area, if his costs are reasonable, I would have several thread sizes made. If enough people were interested I could possibly commission a few batches and sell them for a (modest) profit. If I can relocate the guy I will let you know!
  17. Thanks for posting this Tito, I like the footage! I have the Century 1609 in a Canon Bayonet mount. I've done the step ring hack, but I also acquired a Canon GL1 lens assembly which includes the bayonet. I'm considering making casts of the bayonet (probably in brass) and fixing those casts to step down rings, to live on each of my lenses so each lens can be attached quickly by bayonet, as originally designed. (Though I'm still deciding if it's worth the cost/effort}
  18. Ahh...simple but effective!
  19. Well done!!! What set up did you use for rolling the camera?
  20. Hi QuickHitRecord,

    I read your excellent post about modifying your Bell & Howell into a single-focus unit.  Inspired by what you wrote I have ordered a Bell & Howell in hopes of replicating your modification.  I was hoping that you might be able to provide some additional info on the customization you did.  Particularly details on the 'multi-start thread' front housing you had fabricated in order to reduce the number of rotations required for focusing.  Did the machinist you worked with create any schematic or CAD file?  I am grateful for any/all info you could provide, or just any advice or observations in making & using your B&H lens.  I'd like to document the process it and post it back to the EOSHD forum (provided I can do it successfully). Thank you for your time and consideration!

  21. Thanks Nrubloc, QuickHitRecords had posted pictures in that thread but they are dead links so I wasn't sure. I was really impressed with his footage so I would like to attempt the same modifications.
  22. I am wondering if lens below is the one QuickHitRecord is referring to in this thread: QuickHitRecord posted that thread a year ago, mentioning these lenses are found on eBay for $75-150, but I'm seeing them for $500. I have a line on one in good condition for $250 and I'm wondering if this is a good deal.
  23. Thanks John & dhessel. I will probably stick with a cheap, short-term zoom option for now. The Foton sure is pretty though
  24. Looking a little further, it appears this adapter is probably too small for practical purposes...
