What is the specification of the shutter? Electronically controlled vertical-run focal-plane shutter.
Speed range (Auto) 1/4000~30 sec
Speed range (Manual) 1/4000~30 sec (1/2 EV steps or 1/3 EV steps), Bulb.
What is the feature of 86,000 pixel light measuring sensor? This sensor can measure color too and also, it can be measured in low light condition as -1EV.(with 55mm, F2.8 lens)
What is difference between Multi pattern WB and previous AWB The previous WB had done processing on the entire screen, but the Multi-Pattern Auto WB, which divides the screen into small sections and applies the optimal white balance to each.This function resolves the color temperature differences due to differing light sources, shadow, and sunlight, and provides stable color reproduction that looks similar to the way scenes appear to the naked eyes.
How many Auto focusing point does 645Z has? Total 27 points and 25 points of them have vertical and horizontal line sensors and it will exercise high ability of Auto focusing for every objects.
How many AF points that corresponded to F2.8 sensor? Three AF points at center of screen have F2.8 beam line sensor. When F2.8 lens is used, it will be exercised high accurate focusing.
Can Live View function be used with 645Z? Yes, this model is equipped with the Live View function which can be used for accurate focus checking on a magnified display (max. 16x). In addition to Contrast AF which obtains extremely accurate focusing, you can set Focus Peaking and Face Detect AF. Because effects such as Custom Image and white balance are reflected on the screen, you can expand your range of expression.
Can Shake Reduction function be used with 645D? Not in this camera body. It can be used with corresponded lenses.
What is the specification of the viewfinder? *Field of view: Approx: 98%.
*Magnification: Approx 0.85x (75mmF2.8 ∞)
*Diopter adjustment: approx -3.5~+2.0m-1.
*Eye relief: Approx 21mm.(From the view windows),
*Interchangeable focusing screen. (Common with 645D) There are 3 kinds of screens.
1) The AF frame matte focusing screen DF-80(Standard)
2) The Cross-lined matte focusing screen DG-80
3) The Golden Mean Matte focusing screen DK-80
What is the specification of the LCD monitor? Coupled with a 3.2 inch, approximately 1.037 million dot, large, high-definition, wide viewing angle panel, this feature makes it possible to shoot at low angles and high angles while looking at the Live View display from a more comfortable position. It also features an air gapless construction that suppresses internal reflections. Reinforced glass with AR coating is used for superb visibility, protection from scratches, durability, and is crush resistant..Brightness Color and saturation adjustable
How much is the range of angle for LCD monitor It can moved 35°in a downward direction and 125°upward direction.
What is the new square grids display? Two types of new square grids with a narrower vertical/horizontal line pitch(width) are now available, making it easier to capture images that you plan to merge later, and to make recording usage more efficient. Because the grid pattern is tighter than previous versions, it is easier to match the positions of the main subject image and the image for merging. It is also possible to select 16 zones, the golden ratio, and scale display. Because grid colors can be selected from transparent white or transparent black, visibility is guaranteed, as well.
What is the 180° rotating display/recording? This feature is useful when making copies of images. Normally, when setting materials to shoot at the correct position from the photographer’s point of view, the recorded image is rotated 180° as seen in the right figure. Simply rotate 180° to record the rotate information of the correct position. Because Live View and HDMI output is also rotated 180° and displayed, it is easy to operate while viewing on a computer or TV screen.

* The default setting is [Natural].
What is Dynamic Range (D-Range)? Dynamic range is the ratio that indicates the light level expressed by the CCD sensor pixels from bright areas to dark areas. The larger it is, the better the whole range from dark to bright areas will appear in the picture. By expanding the dynamic range, you can expand the light level expressed by the CCD sensor pixels, making it more difficult for an overexposed area to occur in the image.
What is [Slow shutter Speed NR]? When shooting with a long exposure for extremely dark scene such as night scene or starry sky, image noise (Thermal noise) may become noticeable by produce heat of CCD sensor.
[Slow shutter Speed NR] function can reduce such image noise.
Noise Reduction function can be set ON or OFF in [19.Slow shutter speed NR] in the custom menu.
1: ON:
