Pentax K-3 Mark III Monochrome The Pentax K-3 Mark III Monochrome is a digital SLR camera with an APS-C sensor and approximately 25.73 effective megapixels, producing sharp monochrome images rich in gradation. Monochrome-specific CMOS image sensor The specifically designed CMOS image sensor works by reflecting the brightness data captured by each pixel, rather than the usual interpolation process. This allows for more accurate and extra-fine monochromatic expression, producing high-resolution and rich gradation images. The highly sensitive light reproduction also creates a natural bokeh effect on defocussed areas. Professional-level Image Quality With 25.73 effective megapixels, the back-illuminated sensor produces incredibly sharp images with very low levels of noise. When this
