Hi Satsuki! Good to see you. (virtually speaking)

Hi Nelson. Or Maybe try shooting from another boat? You could set yourself up on a Kayak with a high hat, then shoot boat to boat. If it needs a rigged feel I'm sure you could rig the two boats together with speedrail and let the peddle boat pull the operator in the Kayak.

Good advice on the acetone. Another trick to try is pushing a soldering iron against the screw head. The heat can loosen up the locktite, If you damaged the screw head and can't get it out, the next thing to do is try and drill it out. Use a drill press and move slow. I also recommend having a shop vac suck up all the metal dust it creates as you go. This is a last resort option, but can work.

Hi Gregg, Thanks for watching the video. I did the tests with tin foil, but I wanted a lens with variable focal lengths. If I simply put tin foil over the mount I'd be locked into approximately 50mm. My lens allowed me to have focal length options and quickly change them out. You probably experienced sharper images with stills by using smaller aperture sizes. Even with the camera cranked up to 6400ISO, I couldn't use my smallest aperture options. Perhaps with a camera that has 3 or 4 more stops of sensitivity you'd get those crisper pictures.

Hi All, Thought that the lens forum would be an interesting place to share a music video I recently shot on a custom machined pinhole lens- I machined the lens to have variable focal lengths (25mm, 50mm and 85mm) with an integrated rotating aperture plate. We shot in wide screen with an 18fps time base. Thanks for checking it out. pinthumb.pdf

Still available.

Still for sale.

Hi all. Moved on to a new set of primes and am selling the remaining two lenses from my Nikon set- Nikon 28mm Series E f2.8 = $150 Nikon 35mm f2 = $300 Lenses are in good condition. Both have de-clicked apertures, delrin fitted 32-pitch gears, 80mm fronts and 80mm push-on front caps. (The 28mm has a tiny cleaning mark/scratch that has been on there since I bought it and has never shown itself on an image in any way what so ever.) These lenses can be fitted with a Canon to Nikon adapter and be used on Canon cameras and mounts. I am based in San Francisco and can show them in person if anyone local would like to test them out. Feel free to send me an email if you have any questions- film@jasonjoseffer.com

You might consider having them disassembled and take them to a machine shop to have the paint removed and it to be anodized black,

Hi. Not exactly sure where you are shooting in Africa, but I can offer some advice based on my doc experience in Haiti. Haiti is a hot/humid country which created many over-heating problems for the 7D. I ended up wrapping the camera in white plastic and later keeping it shaded during interviews via an umbrella. The umbrella was a huge help. Of course, a set of ND's and Pola is very useful/necessary. Hope that helps. -jason

Not a "documentary" in the classic sense, but none the less a fabulous piece of documentary filmmaking is This American Life TV series episode John Smith. I was blown away!

Anyone here know which filter(s) were used by Edward Lachman (ASC) in Erin Brockovich? Looks like he may have used a Tobacco or Chocolate filter. Anyone know? Thanks.

Hey guys. I am looking for suggestions on how to simulate a breath. For example, it is cold outside and you can see your own breath. I know I need to backlight it. But how do I artificially create that effect? (fogger inhailed by talent?) Any advice would be a great help.
