    I wish I could be of more help, but I've seen the tide bring in several models of this projector display, all looking like a paint bucket. In terms of covering wider lenses with this bad boy, it seems that if you can't get it done with this, you're probably asking for too much (in which case the school of thought seems to be to just go spherical anyway, since you'd be losing most of the characteristics of anamorphics). As for mounting, I'm sure that if there's a will, there's a way, even if you have to ghetto-rig it until the inspiration for something more stable materializes. Best of luck--I'm particularly interested in the edge performance. And to hell with how silly it looks mounted to a prosumer cam--only the captured image matters!

    I am 3d printing out sizer rings for it so i can mount it to my rails. cant wait to see how it performs, especially at the corners! The flares that I got with it from hand holding were the best I have ever seen.

  2. I made a purchase on Ebay recently for an anamorphic lens. This is the one I purchased.

    It's the exact same version as THIS lens: https://www.ebay.com/itm/ISCO-Anamorphic-Video-Attachment-III-IIIL-1-33x-Lens-3-Widescreen-w-CineSlide-/182674289586?hash=item2a883c73b2:g:Bb8AAOSw9N1VkDQo

     

    I bought it for 1500$. I need to know a bit more about it. I can't find all that much info on it. The best I can tell, its the iscorama 1.33x MkII or III, and that it is a single focus anamorphic.

    Its rear filter thread is 112mm in size, and the front size is MASSIVE. I got it so i can use it with my wider lenses. I can use my 35mm full frame lens without any vignetting, and am planning to make a housing for it so I can mount it on my rails.

     

    Does anyone have some info on it?

    @Tito Ferradans, I heard you mention this lens in one of your videos. Any info?

    I should have mentioned more that I was referring to Full frame performance of these focus solutions...which will always reveal the worse edge artefacts at wider apertures. You will most likely find a suitable taking lens for your APSC camera by experimenting (unfortunately like every single FM owner had to do). The FM seemed to be optimised for smaller than s35 sensor, so Brian's mention of pupil size makes good sense to also consider experimenting with lenses that have a smaller pupil diameter.  

     

    So much to learn. I did not know about this pupil thingy but I had my beliefs that the wider the front element the more the vertical hazing.

    Forget shooting anything wider than f4 on any taking lens and expect to get no glow/smear/hazing highlight aberrations on the FM - or most of the other vari-diopter solutions out there. It is all due the single element design of these diopters - it is simply the optical limits of single element design/ coatings and the glass index used.

     

    Its not about the max aperature. its about stopping down. higher aperture lenses tend to be sharper  at comparable F-stops to other, less light sensitive lenses. Also, besides the aforementioned issues, my zeiss 50mm was suitably sharp for me all the way open at f1.8 with no vertical hazing.

  5. Hey everybody. Haven't been on here in a while since I can't remember my old login credentials (People may remember me as Danson Delta-40). At any, I have a favor to ask.

    I need a specific taking lens that fits a whole bunch of criteria. Here's the rundown:

     

    • The FM Module creates a vertical "hazing" with certain lenses. I need a lens that does not do this.
    • 50mm-85mm
    • f1.8
    • Can fit on my canon 7D with EF adapter.
    • Have LOW barrel distortion
    • Adapter CAN'T have its own lens for allowing infinity focus.

    I have gone through three lenses thus far, and none have fit my criteria

    Nifty Fifty is too light and plasticy, plus for me it created that vertical haloing.

    Zeiss 50mm zebra m42 was good, but its barrel distortion is too high, and although sharp all the way open at f1.8, the flaring would bounce light around and I could actually see a green cast of the iris blades if it wasn't completely open.

    Canon 50mm F1.4 FD would be great, but no matter what adapter I use, it cant do infinite focus with FM module, is waaaaaay too soft because of that, and its the SSC version (Super Spectral Coating) so not so flarey goodness.

     

    Anyone know lenses that fits these conditions? Bonus if it's under 200 :D

     

    EDIT: heres a screen from a video I took with the FM module and the canon 50mm F1.4 FD SSC lens.50mm FD.jpg
