Blog / Learn & Help / Lenses An account of a successful Sigma Lens Day held on 13 February 2020 at VMI Lenses VMI held a Sigma lens day on 13 February 2020 in London. The intention was to show the differences between the Sigma Cine Primes and the new Sigma Classic Primes, which display a lot of character and flare easily. Interestingly, the new Sigma film lenses transfer Cooke/i data and all lens data is captured and can be seen on the display of compatible cameras. We also compared Masterprimes next to the Sigma Cine primes, which compared very favourably and also Cooke Mini S4i and Sigma Cine primes next to Sigma Classic primes using the same camera and iris settings. See video clips at the bottom of this page. Below is a comparison clip of a Sigma Cine Prime compared with a Sigma Classic Prime. Both are 50mm and Full-Frame image size. Both are at matched T2.8 shot on Canon C500 Mk II cameras. It is clear to see how clean the Sigma Cine prime is, even when a spot light is shined directly into the lens, in contrast to the Sigma Classic Prime which flares easily. Below is a comparison clip of a Cooke Mini S4 uncoated lens vs Sigma Classic Prime. Both are 50mm and cropped to S-35 image size. Both are at matched T2.8. As in the above example, the Classic Prime flares very easily. Both shots were made with the Canon C500 Mk II cameras in default configuration at matched settings and matched image sizes at VMI, London on 13 February 2020. Related articles New generation of Auto Focus lenses now available with E and EF Mounts Lenses Auto Focus is here to stay and whilst this is not a panacea to force all focus-pullers to retrain, the increased adoption of Full Frame (which necessarily makes focussing more critical than S-35 or APSC formats) and the enhanced development of the technology, makes this functionality more useful and as a result, we are noticing an increased interest in it. What real world Cinematographers think about using Infiniprobe lenses Cinematography, Lenses The Digital Cinema Society presents an exploration of Micro/Macro cinematography with three DPs including Bill Bennett, ASC, James Mathers, and Cameron Cannon. The trio photograph a variety of shots in order to evaluate these exceptional lenses and also share their insights in behind-the-scenes coverage. Some S-35 zooms already cover FF (you just didn’t know this!) Lenses This is an extremely brief article to help to explain a lesser-known but extremely valuable tip. In summary, film zooms designed to cover S-35 sensors, will also cover Full Frame as well IF used with a 1.5x extender and this is built into several zoom lenses already, such as the Canon Cabrio zooms.
