Lens rehousing company IronGlass recently announced their latest project built around the iconic Zeiss Standard Speed cinema lens series. Preserving the look of the donor glass, their modification aims at expanding the lifespan of these classic lenses by providing fluid, modern mechanics. Pre-orders are now open.A major player in lens rehousing based out of Ukraine, IronGlass rose to fame by modifying vintage Soviet optics for cinema use, and we recently had the chance to conduct a hands-on review of the MKII version of their housings. You can check it out here.However, the company has also started to venture into other lens series. Last year, they launched the Carl Zeiss Jena rehousing project, and more recently, they partnered up with Ancient Optics and succeeded in rehousing the Tokina 28-70mm f/2.6-2.8 zoom – a task that many previously considered “impossibile”. Now, it’s Zeiss Standard Speed lenses’ turn. Let’s have a look!IronGlass rehousing for Zeiss Standard Speed lenses.

Originally, these PL mount cinema optics were engineered for use with Arriflex 35mm film cameras, so they still cover Super 35mm sensors in the digital era.Some of the original Zeiss Standard Speed lenses.

The lenses are known for delivering sharp, natural-looking images, beautiful flares, as well as a soft and smooth bokeh. Almost all focal lengths in the MKII iteration of the Standard Speeds are T2.1, with a few exceptions being the 14mm T2, the 60mm T2.9 Macro, and the 180mm T3.IronGlass rehousing for Zeiss Standard Speed lenses.

One of the most significant improvements is the replacement of the original helicoid focus mechanism with a state-of-the-art CAM-based system that should enhance smoothness and precision when pulling focus. Additionally, the original 80mm front outer diameter of lenses ranging from 16 to 180mm will become 95mm.Price and availabilityIronGlass is now taking pre-orders for their Zeiss Standard Speed rehousing, but please keep in mind that you need to provide the donor glass.
