15 Aug Sirui rehouses its 1.33x anamorphic lenses for cinema rigs and adds T-stops
Source: DP Review
Chinese anamorphic lens manufacturer Sirui has introduced a new set of lenses bases on its existing four models. The Sirui MARS lenses are designed to offer better handling for rigged cameras, and come with built-in mod gears for both aperture and focus rings. The apertures have also been reclassified as T-stops and the focus throw of each of the models has been significantly extended to make accurate focus adjustments easier with follow focus equipment.
While the standard 1.33x anamorphic lenses from Sirui come in a range of mounts, the MARS set is offered only for the Micro Four Thirds system – though the company tells me they are considering other mounts for the future. The focal lengths on offer are 24mm, 35mm, 50mm and 75mm, which correlate directly with the existing lenses. To unify the iris though the f/1.8 lenses now are marked T2, and the f/2.8 aperture of the 24mm is now marked as T2.9. Further modifications to the lenses include harmonised filter threads at 67mm (the existing 24mm takes a 72mm filter) and each of the MARS lenses is heavier and longer than its original equivalent.
From the group shot photograph it appears that Sirui has managed to reposition focus and aperture rings so that they all fall in the same place. This will allow lens changes without too much rig adjustment, helped too by the fact that now each lens has its own 1/4in thread mounting
