The original Bausch & Lomb Baltars are vintage cine glass from the 1930s and 40s — used on Citizen Kane, Casablanca, and a long list of black-and-white classics. Zero Optik rehouses them into modern PL-mount cine housings with matched focus gearing and consistent 80mm front diameter, turning a museum-piece lens set into a working modern kit with deliberate vintage character.

This case carries a 4-lens Baltar set in vertical layout. CNC-cut foam profiles each rehoused barrel to the standardized Zero Optik B&L housing dimensions (which are consistent across the Baltar rehouse line). Vertical loading keeps the case footprint compact, which matters for the otherwise heavy 4-lens vintage kit.

Shell is ATA 300 Category 1 with recessed ball-corner latches, pressure-equalization valve, and a soft-grip handle. Foam is closed-cell polyethylene CNC-cut to spec — holds tight tolerance across hundreds of insertion cycles and won't shed particles onto vintage front coatings.

Built in our North Hollywood workshop. Lead time 14–21 business days. For matched cases with additional Baltar focal lengths or a horizontal-load layout, call 818-767-3030 to expand the case spec before fabrication.

Will this fit my setup?

Tell us what you’re protecting and everything that travels with it. We check it against this build’s foam layout and reply with either a confirmation or the change we’d make. No obligation, and it goes to the people who cut the foam.

We reply with a real answer, usually same business day.

My setup is different

Different body, extra accessories, an accessory that has to stay mounted, or dimensions that don’t exist yet. We modify an existing design or engineer a new one.

I need several

Repeatable foam layouts, consistent hardware, replacement foam and reorders against the same drawing. Standard practice for rental houses and studio fleets.
