Simple, Easy, Tough  of POLARIS is reborn with adding new features!
Easy to see in a large color LCD display, and operation has been further improved with using the Cross Key. In addition, it is a next-generation model that enhance the function of flash light measurement, such as Flash Duration Mode, and Flash Ratio Function.

Flash Duration (FD) Mode: <World’s First>
Measuring the duration time of the strobe flash. T0.5: 1/100 1/9000

Flash Ratio Function:
On Flash measuring, ratio of strobe light to overall light quantity is displayed. (in 1% increment)

Flash Duration (FD) Mode
Flash Ratio Function
Auto ISO Mode:
Setting desired Aperture and Shutter Speed find appropriate ISO number.

Contrast Function:
It shows the difference between average value and newly measured value by ΔEV. Useful for checking lighting evenness of backgrounds, and lighting ratio.
