1.1 Warranty Please read the warranty certificate found in the Quick Guide. Should any problem occur, contact your local dealer (place of purchase) to facilitate a repair. Do not try to repair the camera yourself. An unauthorized attempt to repair the camera terminates the warranty. 1.2 Installation and Activation of Software An Internet connection is needed to activate Capture One.
1.3 Activation An Internet connection is needed to activate and update Capture One. Upon launching of Capture One, an Activation dialog box appears. (On a Windows-based PC the dialog box looks slightly different but the steps are the same). 1. Select Use Capture One DB to activate the Digital Back version of Capture One 7. 2. Click Activate to complete activation. A confirmation screen appears informing you of a successful activation. If you have purchased a license for the Capture One Pro version: 1.
1.4 Screen Calibration Having a properly calibrated monitor is a critical factor when viewing images. Ensure that the digital viewing conditions are as accurate as possible. A quality monitor and calibration tool should help guarantee that displayed images on a screen are precisely rendered. Once a monitor has been calibrated; the color and brightness controls should be locked to prevent inadvertent changes. Hardware-based monitor calibrators are now available at reasonable prices.
2.0 The 645DF+ Camera and Credo Digital Back System The Mamiya Leaf Camera system is created to provide as much flexibility and openness as possible. Follow the instructions below to setup and use your Mamiya Leaf camera system. 2.1 Charging the Batteries for the Credo Digital Back Charge the batteries as soon you unpack the camera system. Although only one battery can be used in the Leaf Credo back at a time, it is recommended to charge both batteries fully before you start.
2.2 Batteries for Camera P M.U Set the shutter release mode selector lever to L (to turn the power off). C S L Use the Mamiya Li-Ion rechargeable battery pack, six AA alkaline or rechargeable AA batteries. (If you are not using your Leaf Credo on a Mamiya 645DF+, skip to page 24.) Li-Ion, NiCd or NiMH batteries should only be used in the camera body if CF04 is set to the specific type of rechargeable battery used.
2.3 Sleep Mode The camera’s power is switched on when the shutter release mode selector is set to S, C or M.UP. In order to prevent the camera’s batteries from discharging, sleep mode is automatically entered if no operations are performed for a specific period of time while the power is ON (with exposure metering status maintained). In sleep mode, operating the shutter button or a function setting button restores power ON status.

4.0 Introduction to the Credo Series Digital Back System Overview The Leaf Credo series digital back is designed to fit on the Mamiya 645DF+ as well as several other brands or models of medium format cameras. The Leaf Credo series include three different models; the Credo 80, 60 and 40 that feature maximum resolutions of 80, 60.5 and 40 high quality megapixels respectively. All of the backs have a dynamic range of 12.5 f-stops. The Leaf Credo backs employ both USB 3.
4.1 Quick Start (shooting untethered) 1. Connect a Leaf Credo digital back to the camera and install the focusing screen if applicable. 2. Charge the battery (see page 12), then insert it into the back and either a Li-Ion rechargeable battery pack or AA batteries into the camera. 3. Insert a CompactFlash card into the Leaf Credo back. 4. Switch on the power to the back and camera and select a drive mode. 5. Choose an exposure mode. 6. Select a focus mode on the camera body and lens if applicable. 7.
4.2 General Hardware Setup Powering up the Leaf Credo back After a Leaf Credo back is connected to a camera body, insert a battery, USB 3.0 or FireWire 800 cable and it automatically turns on. The back is switched on/off by pressing the power button located at the top of the Leaf Credo back. ISO Settings The Credo 80 back has a default ISO range from ISO 35-800. The Credo 60 and Credo 40 have a default ISO range from ISO 50-800.
4.3 Indicator Light Credo series digital backs feature an indicator LED located beside the on/off button. When the Leaf Credo back is in sleep mode, the green LED is illuminated. The LED goes out as soon as the back is activated. In general, if the LED is not illuminated and the back and camera are on, the camera is ready. 4.4 CF Card LED There is an additional red LED indicator located next to the CF card slot (under the cover). It indicates CF card activity.
4.5 Tethered and Untethered Operations Untethered: A Leaf Credo series back can be operated as a fully portable battery powered unit. Image files are shot and transferred to a CompactFlash card which is inserted in the CF card slot on the left side of the camera back. Tethered: Remember to always keep a battery in the Leaf Credo back even when shooting tethered to a computer via a FireWire connection.
Tethered Operations Continued The display on a Leaf Credo series back can be either be turned off while shooting tethered or set to display the images while they are shot, just as if shooting untethered. It is also possible to enlarge a section of an image on the Credo screen to help check focus of the current and upcoming captures. A Leaf Credo back defaults to its untethered mode when the FireWire 800 or USB 3.0 cable is removed in its Auto Storage setting.
4.6 CompactFlash Card Usage It is important to follow a few simple guidelines to help avoid loss of data when working with CompactFlash cards, card readers and digital cameras. Mamiya Leaf recommends that you test-drive all new CompactFlash cards with your Leaf Credo back. By performing an initial test to verify that the capture files are stored properly on the card and can be accessed on a computer you avoid unpleasant surprises on location or when you return from a job.
4.7 Secure Storage System (3S) You can always be sure that your data is safe when working with memory cards in a Leaf Credo back. The Mamiya Leaf Secure Storage System (3S) provides the industry’s safest memory card handling. The 3S technology automatically checks your card’s file structure every time it is inserted into the Leaf Credo back. If the Check Disk function finds an error, it prevents usage of the card until it is corrected or the card is formatted.
4.8 Formatting your Memory Card Most CompactFlash cards are preformatted and ready for use in the Leaf Credo backs. However, Mamiya Leaf recommends that all cards be formatted in the Leaf Credo back to ensure their optimum performance. Memory card formatting is done in either FAT 16 or FAT 32 depending on card size. (Leaf Credo backs support CompactFlash cards formatted in both FAT 16 and FAT 32.
5.0 Navigating the Credo User Interface and Menu System Home Screen The Credo Home screen is the first view that you see as soon as the back is switched on.

1 16.2 Viewfinder Masking The image area of the Hasselblad H1/H2 cameras is 56 x 41.5 mm. A viewfinder mask is only needed for the smaller size of the Credo 40 CCD that measures 44 x 33 mm. Viewfinder masking is not necessary for Credo 80 and Credo 60 models as their light sensitive CCD measures 53.9 x 40.4 mm. Insert a Viewfinder Mask 1. Dismount the prism/waist-level finder. 2. Place the viewfinder mask on the focusing screen. 2 3 3. Re-mount the viewfinder focus screen.
16.3 More Details: Hasselblad H Series Camera Display The Hasselblad H1/H2 incorporates a screen that displays information about the camera set-up. It shows the aperture value, AF mode, shutter speed etc. The Hasselblad H1/H2 also displays some Leaf Credo back information on this screen. For example, error messages including Digital back storage media is full are displayed on the screen if the CompactFlash card being used by the Credo back is full to capacity.
Viewfinder Information The viewfinder information bar is located below the image area within the viewfinder display. It displays the camera’s exposure mode and values etc. It also includes a counter with the number of captures remaining on the storage media (see top bar circled left). ‘99’ is the maximum number displayed. ‘99’ continues to be displayed if there are more than that remaining on a CompactFlash card. An ‘E’ indicates that the storage media is full.
Flash Lead Connection A flash cable is always connected to the Hasselblad H1/H2 camera body. The flash sync cable must not be connected to the camera back when used on a Hasselblad H1/H2. The flash sync connector on the Leaf Credo back is only intended for use with a large format adapter. 16.4 Cables Shipped with Leaf Credo back for Hasselblad H No cables are required to use the Leaf Credo back with a Hasselblad H1/H2.
17.0 Leaf Credo back for Contax 645 The Leaf Credo (Contax mount) digital back is designed specifically for the Contax 645 camera.

Place the bottom of the Leaf Credo back in the locking mechanism. 2.
17.2 Viewfinder Masking The image area of the Contax 645 camera is 56 x 41.5 mm. A focusing screen is only needed for the smaller size of the Credo 40 CCD that measures 44 x 33 mm. Changing viewfinders is not necessary for Credo 80 and Credo 60 models as their light sensitive CCD measures 53.9 x 40.4 mm. Installing the Focusing Screen To remove the original focusing screen: 1. Remove the Contax viewfinder. 2.
17.3 More Details: Contax 645 Exposure Modes The Contax 645 manual (M) and semi-auto exposure modes (Av, Tv) are fully supported by the Leaf Credo back. Please note that Bulb is only supported on Contax/Leaf Credo back when used in conjunction with the Live View function. Go to Chapter 19 (from page 142) for more information about Live View. Check the relevant Contax 645 manual for more information on exposure modes.
TTL flash Using TTL flash with the Contax 645 camera and Leaf Credo back results in a two f-stop overexposure. When using TTL flash, the exposure compensation on the flash unit must be set to –2 f-stops. This overexposure happens because the CCD element reflects light differently than film and this cannot be communicated to the Contax. Image Orientation The CCD in the Leaf Credo back is positioned in a landscape orientation.
17.5 Cables Shipped with Leaf Credo back for the Contax 645 (Gold package only) Part# 50300143 Multi-connector to Lens sync (for use with large format in 2-shot mode) Part# 50300144 This cable is available as a separate purchase only. From multi-connector to mini jack female (to adapt older large format wake-up cables or older Kapture Group 1-shot adapter cables to connect to the multiport).
18.0 Leaf Credo Back on View Cameras The Leaf Credo back is compatible with most technical view cameras and large format cameras via camera interface adapters. The Leaf Credo back supports most mechanical shutters and some electronic shutters from Horseman, Schneider and other manufacturers. Sleeping Architecture The Sleeping Architecture was developed to help produce noise free exposures without the use of active cooling of the CCD.
18.1 Using the 2-shot Release The Leaf Credo back can be used with mechanical shutters that can be fired twice within four seconds. The first release of the shutter activates the digital back; the second release is for the exposure. If the time limit of four seconds is exceeded, the camera gives a warning ‘beep’ followed by a 2-shot error warning that is displayed on the LCD screen.
18.3 Shutter Latency Settings for Technical Camera Adapters Technical camera adapters for the Leaf Credo back can be used with both normal and zero shutter latency. Select the Normal latency setting if the Leaf Credo back is used on a camera with a 2-shot release. Please note: The Zero shutter latency setting increases the power consumption of the Leaf Credo back, as it is always prepared for exposure.
19.0 Live View The Live View function is intended for use when a camera is mounted on a tripod and the subject is stationary. Live View is ideal for use with technical view cameras in a studio environment or for architectural photography, where you would ordinarily have to rely on an external viewfinder or a separate focusing glass/sliding adapter. The Live View function enables you to compose an image directly on the high resolution display of the Credo digital back.
19.1 Starting Live View 1. Live View is accessed from the Camera Settings menu (circled left). The Camera Settings menu is always visible on the Home screen. Tap the Home soft button in the upper left corner of the back to reveal the Home screen if it is hidden. 2. Select Live View from the menu (circled left). 3. When Live View is activated, ensure that a Live View white balance is applied.
19.2 White Balance 1. After selecting the White Balance Picker, tap the screen to select a neutral area to calibrate the Live View. 2. If a precise white point is difficult to achieve in full screen view, slide a finger on the right side of the screen to zoom into a part of the image that you want to use as white reference. Exit the White Balance mode by deselecting the picker in the Dynamic menu. Alternatively, the Home soft button on the Leaf Credo back to return to the Home screen.
19.4 Zoom Zoom into the Live View by sliding a finger up in the left side of the screen. Double tap on the image to bring up a 100% view. If a zoom is already applied, double tap the screen to return to a full image view. 19.5 Grid 1. Go to the Dynamic menu and select the Grid icon (circled left) to apply a default grid. Press and hold the Grid icon to select one of a selection of other grid options to apply to the live view. 19.
19.7 Accessories Live View is easily overexposed due to the high sensitivity of the Credo CCD sensor and its large size. It is sometimes necessary to take steps to prevent overexposure by either stopping down the aperture or by using a neutral density filter (ND filter). ND filters are widely available, and it is even possible to get variable ND filters, that can prove invaluable when working in changeable outdoor ambient light.
