Capture subjects that changes moment to moment with Interval shooting/compositing
The shutter will automatically be activated at the set interval and number of shots. This feature is effective for recording subjects that slowly change over time. Interval Merge with multiple exposure is also possible for use with this function. Intervals can be set from 2 seconds to 24 hours, with a maximum of 2,000 shots, for a variety of expressions.
Automatically generates images with a wide HDR (High Dynamic Range)
A single image with a wide dynamic range is created from three images with differing exposures. In addition to adjusting the exposure amplitude*1 according to the scene, because the camera can automatically correct minor changes to the position of the composition between images*2, you can enjoy easy hand-held HDR photography. Also, because the original three images are saved as RAW data, you can use them separately for development as other creations. All three images are saved as a single RAW file, making data management easy.
*1 : Exposure amplitude can only be set when shooting
*2 : Automatic position adjustment may not be possible for large position differences and due to patterns in some subjects.
Select the composite mode according to your expressive intentions with Multi-exposure capability
Set the amount of shots (from 2 to 2,000) and merge them into a single image. Each time the shutter button is pressed, exposure is adjusted and images are merged, and you can check the results in detail on the LCD screen. You can select the composite mode from three options to match your varied expressive intentions.
Creates a composite image with the average exposure. You can easily enjoy multi-exposure photography without adjusting the exposure for each shot
Creates a composite image of the cumulatively added exposure.
Compares each shot, selects the bright sections and merges those selected sections. Because the dark sections are left as-is, this is effective for photographing the moon, fireworks, or illuminated buildings and other objects when you want to highlight the contrast.
Controls the camera using a smartphone with Wireless Live View shooting
The PENTAX 645Z is compatible with FLU cards equipped with a wireless LAN function. Using the browser on a smartphone or tablet device, you can control the camera while checking the Live View display. In addition to touching anywhere on the screen to start AF, you can set the exposure, ISO sensitivity, release, as well as view and save recorded images.
* Compatible cards: FLUCARD FOR PENTAX 16GB O-FC1 (sold separately)
* Smartphones and tablet devices that use iOS or AndroidTM can be used.
Detects and displays tilt with two directions Electronic Level
This function detects camera tilt in the left/right directions, and forward/backward directions and displays information in 0.5° increments. In addition to monitoring images when shooting with the viewfinder, it is possible to display the exposure bar in the viewfinder. You can also display this function when shooting in Live View, helping you adjust the composition and camera tilt at the same time.
Tripod socket for vertical use
In addition to the bottom section of the camera, the sides are also equipped with tripod sockets. Because the optical axis does not change when switching from a horizontal to vertical holding position, you can efficiently continue stable shooting.
High speed transfer of images to a PC
In studios that use digital cameras, each trial shot is viewed on a computer so that lighting and camera settings can be refined. With the new Image Transmitter 2 software, the PENTAX 645Z can be remotely operated using a computer. In addition to importing images to a user-set folder on the computer, exposure settings such as aperture and ISO sensitivity can be set, as well as activating the shutter while viewing the Live View screen for significantly improved studio shooting efficiency.
For easier compositions with Detailed square grid 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.
Display Live View or images on an external monitorHDMI™ output
The PENTAX 645Z is equipped with an HDMI jack. With this, you can connect the camera to a TV or computer monitor to output Live View or recorded images. This jack provides a variety of uses such as checking images with multiple staff at the same time, and viewing slide shows or movies.
*While the camera is connected to an AV device, nothing is displayed on the camera monitor. Also, you cannot adjust the volume on the camera.
Streamline digital archives through 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.
* Only rotate information is recorded.
Ultra high-speed communication with a PC with USB 3.0
The PENTAX 645Z is equipped with a USB3.0 jack. When connected with a compatible computer, high-speed communication that is leaps and bounds beyond USB 2.0 is possible. This feature makes image transfer stress free when shooting with Live View on a computer.
Key/dial operation lock to revent incorrect operation
The PENTAX 645Z is equipped with a key/dial operation lock to prevent mistaken operation of dials and buttons when shooting. In addition to the front/back dials, this feature temporarily deactivates the buttons mainly connected to exposure controls such as exposure compensation and ISO sensitivity. Additionally, the scope of the locking function can be expanded to encompass virtually every button except for the shutter release button.
