    Plastic melting point is 170C

    Oh I'm not saying it will melt, simply saying that over time the plastic components will experience a loss in overall structural stability.  I had a cheap ASUS laptop that had a mostly plastic exterior and could have fried an egg, and the first part to go structurally was the section closest to the CPU.

    Hold your horses, there is no point in buying a new taking lens if you are not sure which element of the equation is responsible for the abovementioned issue. 

    Just like Julien said, set your Cinelux to infinity (I highly recommend doing this outside) or slightly closer and then, slowly, focus your Nikkor. Don't pay attention to focus distance marks, just look for the sharpest image possible. 

    But, to be honest, I'm not really sure why are you so keen on achieving the infinity focus if you don't plan on getting a single focus solution soon. Does any of your shots require this? 

     

    PS: There are some cheaper solutions, like FVD-16A (550$), which is one of the best on the market, or some Russian focusers going for around 300$.

    Thanks for the kind words, and for the recommendation for the FVD (I'm going to look into that as it's more in my price range).  Any advise on setting the Cinelux to infinity?  I'm assuming I turn the hex screw marked 'focus' on the lens itself?

    I have several front housings with Cinelux, Kowa 16h, Hypergonar and Dyaliscope 16
    And four taking lenses housings : Jupiter 9, Helios, Contax 50 and 85.
    and a rectilux to focus them.

    I just switch back and forth between those, creating different looks, from very clean to vintage fest depending on my mood or what I am planning to shoot. I used the Hypergonar / Helios combination on a TV series last year for close ups that I matched with Panavision glasses, worked pretty well but I felt stuck with the vintage look (figured out later that my Helios was a lemon). That's why I went for the "choose your look" route since then with different options.

    I know. I am sick.

    Julien, do you have any taking lens recommendations for my infinity focus issue?

    Thanks!

    IMO, this lens should work with 100mm to complete avoid vignetting.  And since it is not easy to use as dual focus, focus ring is needed.  FM(Focus Module) was design for it.   

    BTW, 16H/8Z/ELMOSCOPE II are perfect for 85mm without vignetting.

    Thanks for the input.  Unfortunately, I do not have a spare $1k to spend on FM's adapter, although it looks like it would be perfect....

    I am pretty sure your infinity issues are related to your taking lens rather than your cinelux. Sometimes the infinity mark on the taking lens isn't very precise and you have to fiddle with your focus ring to find the exact spot. From my experience with the cinelux, there is no problem reaching infinity as long as the two lenses are perfectly synced.

    As for its sharpness, from my own experience, the cinelux is tack sharp from 1.4 aperture (never tried below) as long as the two lenses are once again perfectly aligned and synced.

    Thanks for your input!  My taking lens is an 85mm Nikkor.  I shoot with a Nikon d750.  Do you have better recommendations?  On my full frame, I am worried about vignetting with anything wider than 85mm....thanks again.


  6. Hello everyone,

    I want to start off by saying that I am a hobbyist when it comes to anamorphic filmmaking, so please forgive my lack of expertise when it comes to questions.

    I have been wanting to get into anamorphic film-making for a while, and I recently purchased a Schneider Kreuznach Cinelux 2x Anamorphic projector lens off of Craigslist.  Research seemed to point to this not being a great lens to adapt due to focusing challenges, but for $150, the price was too good to pass up.  I have successfully adapted the lens to work with my DSLR, see example below:

    A couple of things you may notice about the demo clip:

    • I purposely shot at f/2.8 with a ring light to test blooming and flair.  Flair is absent; you will see some organic blooming around the edges.  This blooming disappears at f/5.6.
    • I also shot at f/2.8 to test center sharpness.  Center sharpness at f/2.8 is very good (YouTube compression does not do this justice).  Center sharpness at f/5.6 is incredibly good.  Edge sharpness is not great, but also not too distracting IMHO.

    Now on to my difficulty (of which I am really hoping someone here has guidance):

    • I am really struggling with infinity focus.  The lens is tack sharp at 6'-7'.  I have four levels of magnification with diopters, so close focus is also not an issue.  However, when I attempt infinity, the lens refuses to settle on focus.  The lens itself comes with a 'focus' and a 'lock' hex bolt on the front of the lens which I am able to turn.  When I do this, I can feel the element moving inside the lens, but focus is still imperfect.  Please don't criticize me too much for this, but there is a big caveat here- tests for 'infinity' have thusfar been indoors; I have yet to test true infinity focus outdoors with this lens (it's winter here), and I am still planning on running tests in that environment (with updates), but before I do so, does anyone have any practical guidance for me?

    Thanks in advance for your guidance.


  7. Can I get people's take on this one?  It looks good abiet overexposed....

    The music video footage is pristine. But was it shot in APS-C or full frame mode?

    If full frame from 46MP, then I am amazed. It's flawless. Not a hint of aliasing and even better than the D850.

    Same question for the guy who posted the N-LOG clip for download in ProRes format. Was that full frame or APS-C?

    What settings Jeff?

    What are your thoughts on this one Andrew?


  8. Yeah, just wanted to point out that the image looks much better in Lightroom.  Uploading it to the boards somehow cooled it down way to much and threw chroma noise into the skin.  Not sure what happened.  At any rate, I'm still impressed.....


  9. Hello everyone.  I just purchase my first anamorphic lens, and I need help with the best base lens for the job.  First here is my gear:

    - Schneider Kreuznach 2x anamorphic lens

    - VidAtlantic adaptor

    -Diopter

    -Nikon d750

    Notice I havent included a base lens.  Since the d750 shoots in fx or dx modes, I am torn between a 50mm lens purchase vs a 85mm lens purchase.  Furthermore, whenever I see these anamorphic setups, the base lens always seems to be an older model (I.e. manual focus and aperture control).  Is there any reason the newest models couldn't be used?

    Thanks in advance for your assistance.  P.S. I will be doing photography as well as film with this setup.
