As title states, I'm having problems with infinity focus on my 18mm Cooke Speed Panchro f1.7 (Arri-S mount, no rehoused) on my RED DRAGON 6K (WEAPON), and there could be a number of factors in play I was hoping someone could shed a light on the most likely issue. The "symptom" (or issue) I'm facing is when turned to infinity, the image is currently out of focus (it's not soft like focusing past infinity, it's actually out of focus - not totally so, but it seems to be focused on a plane before infinity). There are a few things in play here which I will state below (which I think any of which could be causing the issue). (1) I have a RafCamera Arri-S to Arri PL adapter fit on. I'm not new to this adapter, and I'm using 2 of these for my Cooke Speed Panchro 32mm and Cooke Kinetal 50mm respectively on RED GEMINI and RED KOMODO and they work okay, no issue at all. They focus fine to infinity, and focus ring is smooth. However, with this newest lens and adapter I got, without the adapter on, the focus turns quite fine as well; once the adapter is on, the focus ring is noticeably a little bit more resistant to turning (but still turn-able with a follow focus unit). (2) The 18mm CSP seems mechanically different to my existing 32mm CSP and 50mm Cooke Kinetal. The 18mm I noticed has 2 rings, one for focus, one for aperture. The 32mm CSP and 50mm Kinetal does not have a seperate ring for Aperture, and aperture is adjusted by turning the front of the lens. (I'm not sure if this is even a factor, I'm simply stating an observation). (3) My RED DRAGON 6K has a Low Light Optimized OLPF (filter) fit on. I just took over this unit, and it comes with Low Light Optimized OLPF - I'm in the midst of getting the Skin Tone Highlight OLPF instead (because I don't shoot Low Light), and I've kinda read that Low Light generally can affect infinity focus, though again, I'm not sure if it actually causes inifnity focus to go off this much. (4) I'm not sure if my RED DRAGON 6K has had its backfocus adjusted. The backfocus may have been adjusted for the previous lenses it housed, but I'm not sure and I can't really check because the seller was a production house that has clocked over 3.3K hours on the unit, and they've used it with other cameras for multiple productions and shoots - they don't really remember if they did adjust the backfocus on the unit. Although, does backfocus affect infinity focus? That one, I'm not sure. (5) My RED DRAGON 6K uses the older Titanium PL Mount. I'm not sure if this is even a consideration, but it simply is an observation against my RED GEMINI which uses the (newer) Magnesium PL Mount - as far as I know, the difference between the two PL mounts is only in terms of make and weight, but I'm not sure. I'm not looking for the one solution at this stage, but I was hoping to save some time hopefully if I could get help and eyes from more experienced shooters on what might be the most likely culprit as to what's happening here. Thanks in advance!

Thanks in advance for sharing your experience with me. I'm going to be DP on a friend's shortfilm and they want to use the Red Scarlet W with a Dragon sensor. I'm excited about that because I have never used a RED camera, but I have some questions, specially since I won't have acces to the camera pretty much till the shooting day. How do you expose for this camera? I know it sounds like a dumb question but I'm really asking, where do you put your 18% gray? and how's your experience with your technique? I like using my light meter to set exposure, but now with a variety of cameras available and manufacturers putting 18% gray wherever they want it's complicated. Here is my point: I have an Ursa Mini 4.6k and it's a great camera. I tested the camera using an 18% gray card and some other tests and I determined that in order to get proper exposure without correcting in post I have to overexpose the camera by almost two stops. I set ISO 800 on the camera and ISO 250 on my light meter, and I get what I consider proper exposure. There is a video where Shane Hurbult tests the camera and he gets pretty much the same results. I guess it was sort of embarrasing for Blackmagic to say their camera is rated at ISO 250 so they said it's a ISO 800 camera like REd and Alexas, but by doing that they are forcing people to under expose a camera that doesn't have tolerance to underexposure. It's a great camera, if you expose it properly and that is not at ISO 800. I know they are trying to protect the highlights, so their camera looks good, but I know how to take care of my dynamic range and I rather take it to the limits taking my own decisions. Is there something similar with RED cameras? How do you expose for RED specially with a light meter? Do you over expose or underexpose for some reason? Do you get more noise if you underexpose it? How far would you take ISO and still get a decent image? I'm not lazy, I did read the manual, but knowing that manufacturers play games with specs I rather have some info from people who have experience using the camera or I may say the sensor. Thanks in advance for your help.
