Paul Daly Posted April 30, 2020 Share Posted April 30, 2020 Planning to shoot with a Bolex RX5 and Angenieux 5.9mm setup, however I am aware that the Angenieux will be soft if I were to shoot wide open due to the camera body being the reflex version. Am I right in thinking that I'll have no focus issues past f.8? Link to comment Share on other sites More sharing options...
Todd Pinder Posted May 3, 2020 Share Posted May 3, 2020 From f3.5 and up should fix any focus issues Link to comment Share on other sites More sharing options...
Ben Ericson Posted May 3, 2020 Share Posted May 3, 2020 (edited) I have been reading about this a lot over the last week. I had always just assumed that because the fisheyes were vintage, that they were soft wide open. I have learned to work around it. This is the best, most straight forward article I have found on the subject. http://cinetinker.blogspot.com/2014/12/rx-vs-non-rx-lenses.html I've shot quite a bit with the Century 3.5mm and the Century 5.7mm. I recently bought another Century 5.7mm that covers Super 16mm. I This edit below has a lot with the 5.9mm and a few shots with the 3.5mm. I am fairly certain the last few shots in the video, starting at around 2:25, were shot at F4 - 5.6. https://vimeo.com/268666200 In my experience, the best fast wide lens is the Kern 10mm 1.6 RX. Here is a few examples of the Century 5.9mm. The first frame is F11 on 50d. I believe this second frame is F2.8 or F3.5. I didn't use the footage because it was so soft. The difference is obviously night and day. F11 I think this was 3.5... Could have been 2.8. Edited May 3, 2020 by Ben Ericson Link to comment Share on other sites More sharing options...
Nicholas Kovats Posted May 7, 2020 Share Posted May 7, 2020 (edited) Great work, Ben. I have shot alot of footage with my Bolex UltraPan8 2.8 R8 camera and Angenieux 5.9mm Retrofocus lens. Checkout my winter ice bike film where I pushed V3 200T 2 stops (800 ASA) in the lab. The resulting footage was not color-corrected in post regarding the rink (sodium?) lighting. I shot wide open at T2.0/2.8. I think the Angenieux 5.9mm held up. No stabilization. I was skating with my Bolex and chasing cyclists. I would like to have this footage re-scanned at higher resolution and bit depth to bring out even more detail as the original scan was a 3.5 K image sequence 8-bit jpeg.

Paul Daly Posted May 10, 2020 Author Share Posted May 10, 2020 Thanks for all your help, and great work on show too! I've been extra safe on recent shoots and not gone below f/8, fingers crossed all will be well. Link to comment Share on other sites More sharing options...
Patrick M P Donnelly Posted August 9, 2021 Share Posted August 9, 2021 Kowa make machine vision lenses, no, don't laugh yet, designated for 1 inch digital sensors. 4.7mm and 6mm. The latter covers Panasonic GH4 in video 16:9 mode completely, a crop factor of c. 2.3~2.4 to 135 format. S16 is c.2.7 crop. So should cover S16 as well. Not too expensive, in used condition. $400 or so.https://www.youtube.com/watch?v=ZNZsPUBJABAhttps://www.youtube.com/watch?v=LkM5Sjj2dzI&t=152shttps://www.youtube.com/watch?v=gki1pdaihZYhttps://www.youtube.com/watch?v=M0mka9uumkkhttps://vimeo.com/103893379 https://www.youtube.com/watch?v=eEh42ahsEWMhttps://www.youtube.com/watch?v=xlxwwH8IPrM&t=81shttps://www.youtube.com/watch?v=BySiqe9nAeI The 4.7mm is unknown as to cover but should do nearly as well. Pricey.... 1,300+ new. Ergonomics are awful, and contrast is modern. 100 lpmm and very low distortion. Link to comment Share on other sites More sharing options...
