LFL - Lens & Filter Library
Richard William Preisner posted a topic in Lenses & Lens AccessoriesHi all, I just wanted to share a new online library that I've been working on with my focus puller to share our lens and filter tests with other filmmakers, cinematographers, directors, camera crews etc. It's called the LFL - Lens & Filter Library and is available at rwpreisner.com/lfl So far there are over 80 lens and filter tests with many more to come in the next few months. It's currently in the early stages of development and I'm looking for feedback to see how useful people find it to be and what improvements they would like to see. I'm also looking to see how useful the choice of tests are to those that use the library. It's available to be saved as a quick shortcut on IOS & Android devices so can essentially function as an App on Ipad and Android as well as the videos being available in 4k for viewing on larger monitors. It's appeared a couple of times in the BSC magazine news and they have been supportive. You can read their short article about it here Have a look and it'd be great to know your thoughts!
Sony Scl-p - Experiences?
Simon Bentin posted a topic in Lenses & Lens AccessoriesHello dear community, Due to an upcoming project, I was looking to purchase an additional cine lens. In my search for something affordable, I came across the Sony Scl-p series. So the ones that were originally built for the F3, F5 and F55 cameras. However, I can hardly find any info on the lenses. Neither test reports nor comparable. Therefore, the question if someone has experience with the lenses and knows if they are any good. Thanks in advance.
Hi all, I thought you might like to know all about the new and VERY rare LEITZ PRIMES from Leica/Leitz! They're spherical cine lenses and produce incredible, vintage-like rainbow flares. Leitz claim the Leitz Primes are ‘the best of the best’. As Shift 4 are the only UK rental company stocking this state-of-the-art lens set, they invited some of the UK’s most talented Cinematographers, DoPs, Focus Pullers and Camera Operators to a lens test and also shot a short film to investigate the Leitz claim. Then they wrote an article all about them. Read the full article here - it includes downloadable 6K RAW files, which I thought you might be interested in so you can make your own assessment on them! Suitable for high-end productions, you may have already seen the Leitz Primes in action. Seamus McGarvey BSC ASC ISC shot Cyrano (2021), awarding him a nomination at the BSC Awards for Best Cinematography in a Theatrical Feature; Balazs Bolygo BSC HSC used them on the Netflix series Anatomy of a Scandal (2022) and Tony Miller BSC shot the highly anticipated Mr. Malcolm’s List (2022) with the Leitz Primes, which is coming to screens in July 2022. The Leitz Primes are full frame, fast and spherical lenses, designed from the ground up and are very different to other Leitz lenses. Shift 4 have a set of 12 focal lengths available (ranging from 18mm-180mm) and sought to offer the community a varied and professional review of their capabilities. Get your RAW footage HERE!
Questions about camera and lens testing
Andrew Plaza posted a topic in General DiscussionHey all - was looking to get some insight as to what other DPs like to test for when given the opportunity to test cameras and lenses for picture. Even as far as to what tools you might recommend using to help the testing process like a light meter, etc. For this purpose let's assume the test is for digital camera bodies. I'll soon have access to a RED V-Raptor 8K for testing and my personal Fuji X-T4. Two completely different camera bodies but for myself I really want to compare the dynamic range and how far I can push them in the post-room when comparing the two. I'd like to place them in high contrast lighting situations - anyone have any insight here as to what they like to do/use? Is there anything else you would test for? I'll also have access to a set of IronGlass lenses - rehoused vintage soviet lenses. Anything in particular you test for or even a high-level/general idea of your mindset going into a lens test? Testing for how images look like wide open versus closed down, flaring, etc. Any insight here would also be greatly appreciated. Links to other videos or tests would be welcomed too. Thank you all.
Lens test due to change in camera
Mathew Collins posted a topic in Lenses & Lens AccessoriesHi, 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.
Lens test: Ang
Lewis Martin Soucy posted a topic in Lenses & Lens AccessoriesHi, 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
