We present the characteristics and the performance of the new CCD camera system, SNUCAM- II (Seoul National University CAMera system II) that was installed on the Lee Sang Gak Telescope (LSGT) at the Siding Spring Observatory in 2016. SNUCAM-II consists of a deep depletion chip covering a wide wavelength from 0.3 μm to 1.1 μm with high sensitivity (QE at > 80% over 0.4 to 0.9 μm). It is equipped with the SDSS ugriz lters and 13 medium band width (50 nm) lters, enabling us to study spectral energy distributions (SEDs) of diverse objects from extragalactic sources to solar system objects. On LSGT, SNUCAM-II offers 15.7  15.7 arcmin eld-of-view (FOV) at a pixel scale of 0.92 arcsec and a limiting magnitude of g = 19.91 AB mag and z=18.20 AB mag at 5σ with 180 sec exposure time for point source detection.
