Hi, I was working as a camera assistant for one movie. We used Redone-MX and Carl Zeiss CP.2 lenses for almost 90% of the movie. Later there was a fault in the power chord of the camera and we started using Red Epic-MX. Before using Epic, The focus puller tested the lenses with RedEpic. He measured the distance from the lens mount to a subject by holding the tape near to lens mount. That was 10ft. There he tested each lenses on Epic. Following are the focus mark for each lenses 15mm - No issues 21mm - Focus at 8ft 35mm - No issues 50mm - Focus at 9.6ft 85mm- Focus at 9.9ft 135mm- Focus at 9ft I have few questions. 1. What is point on the camera to hold the tape? 2. In above case, is the subject distance measurement correct? 3. Is this testing is necessary while changing the camera? Is it due to the change in flange focal distance? 4. What are the other tests required while changing the camera? 5. Is there any specific charts available for tests? Please share your inputs.
Hi, here's a quick lens test I made with a new lens I just got. I bought a used Angénieux 70-210mm f/3.5 with a Leica R mount which I adapted on my Red Epic via a Novoflex Lens Mount Adapter - Leica "R" Lens to Canon EOS Body. It's a great lens, handmade, very well built, made in France in the early 80's. My Epic was set to 800 ASA, RC 8:1, 5K Widescreen, Redgamma 3 and no filters. Everything was shot indoor daylight on a hazy (sometimes slightly bright) sunday afternoon. I ran my footage through Redcine X Pro only to export screenshots. I didn't grade anything and didn't alter the footage in any way. I shot every scene framed as accurately as possible to make the comparison easier. As you can see, the Angénieux is much warmer and soft than the Canon. I really like it. Here it is: The first interesting factor is that the lens is 770g lighter, almost half the weight an size on the Canon (although my Canon is Cinemoded), making it really nice for run and gun handheld style shooting. I plan giving it a Cinemod by Duclos, like I did with my Canon lenses. But in my opinion, the true advantage of these old school pre auto focus era lenses, is that the focus ring stops so you can really shoot cine style, with proper focus marks. I know my 1st AC will love it... And the really good news is that it holds focus AND aperture throughout the zoom! http://farm8.staticflickr.com/7293/11782705064_4c5b3d8768_o.jpg And here's a little bonus with some live footage at the end... :) [video=vimeo;83443840] Here's some original 80's coverage and reviews in french (you can understand some interesting detailed technical specs i'm sure even if you don't speak french!): http://farm3.staticflickr.com/2842/11811579956_88c30a38d3_o.jpg http://farm4.staticflickr.com/3712/11811247304_4ce7b9a9bf_o.jpg http://farm6.staticflickr.com/5527/11810832605_c3afeb0915_o.jpg http://farm4.staticflickr.com/3784/11811247974_c4d310c26c_o.jpg
