  1. Does anyone have image grabs of frames that show the supposed streak that happens in the S16 space when the mirrors are not adjusted? Image grabs that show the scratch marks in S16 space when the magazine is not modified? I'm converting my SRII to Ultra-16 to avoid costs of Super-16 conversion, but want to double-check if I can't just go all the way and do the S16 conversion, then just crop around the streaked/scratched parts (if by chance they tend to happen only on corners?). My camera has already been modified to use M42 mount 35mm lenses, so realigning the lens shouldn't be necessary, and I can frame by eye without a realigned viewfinder, so the only concern is scratches/streaks on the film.
  2. I'm looking for an ND filter that goes behind the lens (so it doesn't darken the viewfinder) on a CP-16R. I see the little slot for the lenses, and I've read of people referring to them in the forums, but I can't find them when I search online to purchase. Do they have a specific name? Are they a universal size / interchangeable among camera models? The guy at my local vintage/used camera store sort of knew about them but said he didn't remember what they were called.
  3. Yea the first time I watched it on my phone and couldn't really notice it, but on a computer screen it's visible. This is also an SD scan, so if I can see it here it would be even worse in a 2K scan (the format I would telecine the final product in)
  4. Hi Jay, Thanks for your reply. The only thing is that you can see the flicker through the entire test, even in the shots indoors. In all the different lighting schemes, the flicker is the same, I think it's just more noticeable in the overexposed shot. And the flicker is in the center of the frame, not the edges, like I'm led to believe the CP-16R with bow tie shutter causes.
  5. Hi, not sure what forum this belongs in. I did a very short camera test for my CP-16R. I have a CP-16A which I've shot with and never had problems, but I bought this R model to use prime lenses on it instead of the standard angenieux. I have the bow-tie or butterfly model that is infamous for light streaks in the upper right corner, so I was testing for that. It doesn't look like I got any of the streaks people associate with this model (maybe I didn't have bright enough subject matter in the upper corners?) but... there is a subtle (but constant) flicker in the center of the frame. It looks like what might happen when you take your eye away from the viewfinder, but a camera operator of mine made that mistake once last year and I since then I always make sure to keep my eye firm against the viewfinder. Wondering if it could be because I shot at 12FPS (to save film stock and development/telecine $$)? I did forget to tell the lab that I shot in the slower frame rate. Could that affect the way they telecined it and caused flicker during telecine that aren't on my negative? I remember when I tried to DIY telecine some Super 8 footage at home by removing my DSLR's lens and projecting straight onto the sensor, the image was great but I ended up with white streaks and flicker every 4-6 frames, and I guessed it was because the projector was old and I couldn't get an exact frame rate out of it (adjusting the frame rate knob would worsen or better the light streaks). Or is it more likely a light leak somewhere? If it's a light leak could I solve this problem by enclosing the camera in a dark bag during filming (which could also act as a second sound blimp anyways)? I'm going to run another camera test before I start principle fotography, but wanted some advice on what to try and change for the second test. Here is a link to the video of the test: https://vimeo.com/226261458 Any help/input is appreciated. -Omar Lopex ana-film.com
  6. I had an adaptor machined to fit a set of 35mm super takumar lenses (28mm, 35mm, 135mm, M42 thread) onto the CP mount of a CP-16R. I have used these lenses before with a K3 with no problems. I have the CP-16R model with a bow tie shutter and have just recently become aware of the smearing problem they are notorious for. -will the coating on the super taks help avoid the smearing? -will stopping down to F8 and smaller help avoid smears? (I will be shooting on vision 50d and 250d, using mostly natural light but also some 1ks for indoors) Any advice in how to avoid smearing, and any precautions I might not be aware of in using these m42 primes on the camera, would be greatly appreciated.
