Developed as the third generation of the renowned "Super Field Camera" series, the 645NII incorporates all the outstanding features of its predecessor, the PENTAX 645N, while incorporating several features designed to further improve performance, maneuverability and user convenience. With all these exciting features, the 645NII is expected to be a favorite of uncompromising professionals and advanced amateurs, both out in the field and in the studio.
The 645NII incorporates the PENTAX-developed SAFOX IV phase-matching autofocus system to ensure accurate focusing not only on subjects with vertical orientation but also on those with horizontal orientation - even under such poor lighting conditions as EV-1.
The 645NII incorporates a "Dual Six-Segment" multi-pattern metering system. Two sensors positioned at both sides of the viewfinder measure the subject's lighting condition in two different areas: the wide sensor covers the entire image field, while the narrow sensor monitors the light reaching the central area of the image field. As a result, the 645NII can measure the subject's lighting condition with exceptional accuracy and efficiency. In addition to the Dual Six-Segment metering, the 645NII also offers the pinpoint "Spot Metering" and conventional "Center-Weighted Metering" modes.
The 645NII's four distinctive exposure modes allow the user to react effortlessly and efficiently to every situation and create the desired visual effect with ease: "Programmed AE" for adjustment-free shooting; "Aperture-Priority AE" to emphasize the depth of field; "Shutter-Priority AE" for sports and action photography; and "Metered Manual" for maximum control over exposure settings.
A built-in motor drive advances the film at the speed of 2.0 frames per second. Thanks to the high-precision pulse-count film transport mechanism, the spacing between frames is identical and the number of frames which can be taken from one roll of film has been increased from the 645 (16 frames from 120 film and 33 frames from 220 film). This motor drive also offers two film advance modes: "Single Advance" to advance one frame for each shutter release and "Consecutive Advance" to successively advance the film as long as the shutter release button is depressed. In addition, the motor drive automatically loads the film and advances it to the first frame, and winds the film into the film holder to avoid accidental exposure during film changes.
