Introduction of Pentax 645D

Pentax 645D adopts a large CCD photosensitive element with 40 million effective pixels, with a maximum pixel number of 4,065,438+million and an area of 44 x 33mm, which is 1.7 times that of ordinary 35mm full-frame cameras. The combination of PRIME II imaging engine with high performance and high speed response and 14-bit A/D converter can achieve high-quality image quality with high resolution and clear color. The back of the fuselage uses a large optical viewfinder with 98% field of view and a 3.0-inch LCD screen with 920,000 pixels. Pentax 645D adopts a newly designed high-precision 1 1 wide-area SAFOX IX+ focusing system, with 9 o'clock in the center as the cross focus, to accurately capture the subject. Focus can also choose 5-point or 3-point focusing mode, and AF focusing can choose three modes: automatic/selective/central. TTL full aperture 77 differential volume metering system, multi-zone metering, central button metering and single point metering are adopted. It also has many functions of Pentax: custom image mode, HDR photo shooting function, electronic level, CTE white balance, reflector locking function, copyright information embedding and so on.
