High-brightness in a small package
RZ21K is the number one compact and lightweight projector in the high-brightness class and it has the smallest footprint of any 20,000lm projector. At just 49kg, it’s also extremely lightweight and easy to handle, making it perfect for rental or stage use. The RZ21K is almost the same size as the DZ21K2 and will fit in the same frame.
Incredible colours
If you’re looking for vivid colour and unbelievable brightness, the RZ21K delivers. It combines 3-Chip DLP™ imaging with SOLID SHINE Laser Phosphor technology to give stunning image quality. Solid-state laser light sources and specially engineered heat-resistant phosphor wheels work together with three discrete DLP™ modules (R/G/B) for high brightness, true colour accuracy, and high contrast in large venues: ideal for exhibitions, show and other large events. The RZ21K is compatible with the latest colour space standards so you can be sure it will reproduce images accurately.
Project from any angle

The RZ21K is compatible with all of our existing 3-Chip DLP lenses including our ET-D75LE95 ultra-short throw lens to make it easy to install, even in tight spaces like galleries and exhibitions. Thanks to SOLID SHINE Laser technology, the projector can handle 360-degree installation through any axis: it can be mounted at whatever angle you like without distorting the picture.
Failsafe design means the show will go on
The RZ21K uses 3-Chip DLP™ for high-quality, high-brightness projection and colour uniformity that lasts forever. The RZ21K’s mounting structure has a rigid design to prevent external vibration affecting the image.
What’s more, it’s completely dust resistant: the laser modules are hermetically sealed so dust can’t get in and the projector has a very efficient filter-less design – a world first. Plus the New Durable Dust-proof Optical System means you’ll get stable projection even in dusty environments. The Dust-proof Optical System and high-performance cooling system combine to give you 20,000 hours of maintenance-free use (in light source output normal mode).
More of what you know and love
With the DZ21, Panasonic created a reference model for large venue and rental projectors. The RZ21K builds on the DZ21’s heritage to give you improved performance along with the inputs and menu layout you’re familiar with. It works perfectly with the DZ21 and DZ21K2 thanks to Mix&Match feature. And thanks to our patent-pending Contrast Synch technology, the RZ21K offers dynamic contrast with high contrast of 20,000:1 even when used in multi-projection applications.
