As with the higher specification FASTCAM SA1 and SA5 models in this series, the FASTCAM SA4 camera utilizes the same CMOS sensor with a 20µm pixel delivering an ISO light sensitivity of 10,000 (monochrome) and 4,000 (color), both measured to the published ISO 12232 Ssat standard.

Maintaining a square aspect ratio of 1024 x 1024 pixels for frame rates up to 3,600fps is extremely useful when the system is coupled to a microscope, borescope or when observing events such as combustion through optical access windows.

With the benefit of variable region on interest (ROI) to match the aspect ratio of the subject, the FASTCAM SA4 can capture images at a maximum frame rate of 500,000fps and a one microsecond exposure eliminates motion blur.

Lenses designed for both FX (35mm full frame) and also DX (APS-C digital SLR) formats are fully compatible with the FASTCAM SA-4, SA1 and SA5 at full image resolution and these cameras are supplied with both C-mount and Nikon F mount lens adapters. The Nikon adaptor is compatible with new “G” type lenses that do not have a manual iris/aperture ring. An optional Canon EF lens mount permits control of the lens aperture and focus through our Photron FASTCAM Viewer (PFV) camera control software.

The FASTCAM SA4, SA1 and SA5 all connect easily to your laptop through the Gigabit Ethernet port, provide both dual composite video and HD-SDI BNC outputs and can be operated using the optional LCD keypad.
