Blog / Resources / 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.
