    It's done! Really happy with it especially when compared to the Sankor 16-S I had a couple years ago. It's pretty heavy but not too bad. The RAFCamera clamps are absolutely perfect and excellent quality. The posted shot was literally me running out into the alley and snapping a shot on auto. Thanks for everyone's help on this!

    Here is some crappy test footage I've made using my B&H mod.  The first test uses a 14mm helicoid, with the original polyurethane/prototype housing:
     
     
    The second test uses a 30mm helicoid (which allows focus down to about 8-9 inches) and a custom-fit aluminum housing that replaces the polyurethane:
     
    All footage was shot using my beloved silver Helios-44.  Except for a few underexposed shots where I boosted the brightness, all footage is straight out of the camera & unaltered (I'm far too new at this to attempt color grading, anyways).

    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 forum in case anyone else may find it useful.

    Thanks for the update Nick!  Bummer that the Helder didn't work out, but it opens the door for experimentation with other glass element to perhaps get a sharper, wider field of view.  Keep on tinkering!
    Thanks!  Would love to see pics of your setup once you get your collar back from the machinist!
    I am extremely pleased with my final product, and will be making it available for purchase to those that are interested :-)

    Unfortunately, the helder ended up being a bust. While I loved the added width, corner sharpness was awful, extending ridiculously too far into the middle of the frame. It would be useable for close ups, but I wanted it for landscape : /. Your aluminum ring looks great @Bold! Again, I am still waiting on mine....
    In other news, I was able to get infinity focus with the original optics. I will post images once I'm home.
    I also found that the Helder adapter can be used as a range finder, it's optics are strong enough! Could be a viable solution for smaller anamorphics to avoid those corners, just gotta house them in a helicoid. Now if I could only crack open this Sony adapter...I am still so impressed by the quality of the glass in that thing....

    It indeed looks like either part of an optical printer or reconfigured to or from print duplication use. Seen this lens being re-sold 2 or 3 times from different sellers without much time between auctions - which raises alarm bells as to its real practicality for filmmaking use (and where is footage of it at infinity and variable stops?). No doubt the optics are going to be top notch but I'd want to be assured that its focus can hit infinity with that aperture inside (causing added space between optics), since I would presume that lens was always intended for closeup duplication use, as part of a specific optical printer or telecine machine. I suspect that the variable aperture inside the lens is not going to make the image much sharper when coupled with a taking lens, but rather cut the light transmission to the taking lens and dramatically increase vignette.
    In a nutshell, if it was the wonder lens that it is supposed to be, where is example footage of it resolving infinity focus and its results when stopping down with its internal aperture?
    EDIT: Found an expired eBay auction that sold for $250 that confirms my hunch...
    "This is is multiple lens assembly that was used at Deluxe Film Laboratories in Hollywood for 35mm anamorphic conversion to flat formats for theatrical trailers.  It should not be confused with camera or projector lenses.  Printing lenses are ulta sharp intermediate lenses designed to resolve 35mm camera original high resolution color negative without distortion.   The assembly consists consists of three separate lenses, each of which may be separated for individual use:
    Isco Lens VII - Base Lens
    Isco Anamophis Printing Lense 2x with Manual IRIS Ring (Like F-Stop)
    Isco Lens III - Output Lens
     


    I highly doubt the Isco printing lens can hit infinity without stopping it down to a crazy small aperture. You can see from the original configuration that it is basically used for near-macro focus distances, as part of an optical conversion chain. If it could indeed be used for filmmaking use, I would be interested to hear how on earth you would achieve infinity focus. 
    I think the current seller on eBay is a member of this forum @Hunterj11
    perhaps they can shine some light on this lens?

    The cheapest you can go with good quality is with buying either :
    - an Isco Ultra-Star (the golden or red version) you should be able to find some around $200 (got mine for a lot less)
    - a Sankor 16D (or similar : Singer 16-D, Elmoscope I)
    You'll get a dual focus system with great optical performance (Isco is super sharp but doesn't flare, 16D is not that sharp at wide apertures, but it does flare)
    Either way, you should pay more than 200€ for that anamorphic adapter.
    You'll then need to find an adapter to be able to use it. Go grab a Redstan clamp, Rapido Clamp (or a vid-atlantic clamp if you're really down on money) usually between $50 and $100
    So, No, you don't need to spend thousands to get decent quality. You just need to spend wisely. (Of course there are better anamorphic lenses out there, but as you are just dipping toes, there's no rush !)
    Be careful, by tipping a toe, you are entering the madness of anamorphics. Once you bought one adapter, there is now coming back. This is a point of no return !!! :D

    Bold reacted to Bioskop.Inc in Transcoding anamorphic footage   
    What I do, with FCPX, is create a timeline with the desired stretch format (2048x858 - 2k 2.39:1) & then stretch the footage - as i'm shooting on 16:9, the edges do fall outside the timeline's borders. It all depends on what your NLE will let you do - some might not let you make custom timeline sizes & then you'll just have to adjust the height of anamorphic footage, so you end up with black bars on the top/bottom.
    If you still have to transcode your footage to an editable format, then yes, your best option is to do the stretch/squeeze then.
    I stick to Cinema DCP standards:

    @Bold you're machinist is a lot faster than mine, excited for the pictures.
    I've made a huge (at least I think so) discovery in terms of getting wider with this lens...
    My Helder .45x wide angle adapter arrived and my camera came back from repair and I got right to testing it out. As it turns out (and so I feared) the Helder is not .45x like the Sony is .7x, but more relative to the Sony more like .8x––so the Sony is actually wider. Not too upset with my $20 let down, I took the adapter off and noticed it was two pieces, a macro element and a wide element. In a fit of curiosity, I removed the front focal element of the B&H from my helicoid and replaced it with the wide angle part of the Helder. What do you know, it worked! Not only did it work, it seems to allow better infinity and a serious added wideness to the taking lens, as well as bringing close focus down to around 5 inches. On top of the added wideness of the 2x anamorphic, there seems to be an around .7x wideness added by the Helder element. Even better, it appears to eradicate the infinity focus issue, as well as bring my close focus down to ~4 inches!
    Some test video with a Canon FD 50mm f/1.4 (Take note of how wide it appears) on BMMCC (s16):

    I love the closeup on the eyes!
    In regards to the WA adapter, tests on my modded B&H produced poor results.  I believe this is because the helicoid sets the WA adapter too far from the front element of the B&H.
    I've decided to bite the bullet, and engage a machinist to create an aluminum part to replace my polyurethane.  We reviewed all the pieces my mod to ensure that this new part will fit properly in my custom support bracket. I should have a final product in a few weeks.

    Cheers. It was a quick test with Magic Lantern x5 crop mode with diopters on a regular anamorphic setup...I could have gone way closer, if I used a different taking lens (and will do in my next test).
    So to answer the question, it was a bit of both - closeup ability, with an effective sensor crop of the full frame by using ML crop mode. The subject of these stills was a 3inch diameter glass ball with shower gel/glitter and other liquids poured over it - and let to run down the surface to diffract and sparkle at different depths. It was an experiment to see how easy it is to create ambient light / fluid effects.

    Ive got lots of old enlarger lenses I've put into Chinese helicoids that work really great for macro work...extreamly sharp and extreamly cheap, so I'll probably dig those out soon for a better test.
