The name comes from the ground glass focusing screen found inside motion picture camera viewfinders. It's where the cinematographer evaluates the image before it reaches the sensor or film gate — the critical point of reference where creative and technical decisions converge. That's what we aim to be for the used equipment market: a clear reference point.
Ground Glass is a curated directory of trusted dealers specializing in used professional cinema equipment. The used cinema gear market is fragmented across dozens of independent dealers, marketplaces, and rental houses — with no single resource bringing them together for working cinematographers and production companies. We curate only vetted, professional dealers — no consumer marketplace listings, no unverified sellers.
Brands we cover: ARRI, RED, Sony CineAlta, Canon Cinema EOS, Blackmagic, Panavision, Aaton, Cooke, Zeiss, Angénieux, Fujinon, Tokina, Leitz, Hawk Anamorphic, Sigma Cine, and more.
Why Use a Directory Instead of Searching Directly?
The used cinema equipment market is fragmented across dozens of specialized dealers, regional rental houses, and international brokers. Ground Glass consolidates these sources into a single directory so that cinematographers and production companies can quickly compare options, find the best deals, and buy from verified professional sources. Every dealer listed has been reviewed for legitimacy, professional standing, and relevance to the high-end cinema market.
Buying Guides
How to Buy a Used ARRI Alexa
The ARRI Alexa lineup remains the gold standard in digital cinematography, and used Alexa cameras represent outstanding value. When shopping for a used ARRI Alexa, Alexa Mini, or Alexa Mini LF, check the sensor hours (available in the camera diagnostics menu), inspect the PL or LPL mount for wear, verify that all accessories (EVF, power cables, media) are included, and confirm the camera runs current firmware. A used ARRI Alexa Mini in good condition is one of the best values in cinema today. Look for dealers offering sensor inspection reports and functional testing — all of the dedicated dealers on Ground Glass provide this level of service.
How to Buy Used RED Cinema Cameras
RED cameras — including the DSMC2, V-Raptor, and Komodo lines — are popular on the used market due to their modular design and ongoing firmware support. When evaluating a used RED camera, check the sensor for hot pixels, verify the OLPF (optical low-pass filter) condition, and confirm the camera is not locked to a rental house or previous owner. Used RED V-Raptor and RED Komodo units are increasingly available as productions upgrade. Ground Glass lists vetted dealers who specialize in used RED cameras and can provide full diagnostic reports before purchase.
Buying Used Cinema Lenses: PL Mount, Cooke, Zeiss & More
Used cinema lenses — particularly Cooke S4, Cooke S7, Zeiss Super Speeds, Zeiss Supreme Primes, and Angénieux zoom lenses — hold their value well and are a smart investment for owner-operators. When buying used PL mount cinema lenses, inspect the lens elements for coating damage, fungus, or haze. Check the iris for oil residue and verify smooth focus and zoom ring operation. Lens collimation should be tested with a projector or chart. Many of the lens specialists listed on Ground Glass offer collimation and CLA (clean, lubricate, adjust) services as part of the sale.
Used Cinema Equipment Price Guide
Pricing for used cinema equipment varies based on condition, included accessories, sensor hours, and market demand. Generally, a used ARRI Alexa Mini trades between $15,000–$25,000 depending on configuration. Used RED V-Raptor bodies range from $12,000–$20,000. Cooke S4 prime sets (6-lens) sell for $18,000–$30,000 used. Zeiss Super Speed sets go for $8,000–$15,000. Prices change frequently — checking multiple dealers on Ground Glass helps you find the best current deal.
