3 4. FEA TURES A V AILABLE WITH QTTL (D, Dw , Dw-R SERIES) ADAPTERS Quantum’s QTTL ® adapters provide a dedicated link between Qflash 5d-R series and popular digital and film cameras. W ireless multiple ratio TTL - with Dw-R series Adapters & FreeXWires, remote Qflashes can be set to ratios of the camera’s TTL metering system.
4 5.2 Reflectors and Bare Bulb Reflectors are secured by the locking ring near the base of the reflector . Rotate the ring in the directions shown in the diagram to loosen or tighten the reflectors. When inserting a reflector , first slowly rotate it until the notch in the reflector “drops” fully into head of the Qflash.
5 5.4 Bracket Mounting Qflash mounts with a 1/4-20 standard tripod thread to brack- ets, light stands, and tripods. Many brackets are made especially for Qflash by popular bracket manufacturers. Quantum has two optional brackets, models QF70US and QF70E.
6 6. BASIC NA VIGA TION This Section explains how to maneuver your way around the Qflash 5d-R V ery Important T ips For consistent exposures with your digital camera and Qflash.
7 7. COMMON FEA TURES 7.1 Flash Ready The Flash Ready indicator will blink while Qflash is recycling. It will stop blinking once the flash is ready to fire again, and the speaker will beep. If flash readiness is supported by the camera, then an LED or flash sym- bol will appear in the viewfinder when the flash is ready .
8 7.5 Auto Focus Assist The D/Dw/Dw-R series QTTL Adapters will project a beam whenever the camera is having difficulty focusing due to low light conditions. A local Qflash must be connected for this feature. T urn the auto focus assist switch of the QTTL Adapter to on ( ).
9 (optional Bare Bulb Enhancers QF62Bs and QF62Bg) and TELE (for optional QF63B T ele photo reflector). The reflectors must be repositioned manually . Notes: When using QF62B s/g the manual parameters are accurate only for an open area. In medium and small rooms the very widely dispersed light will bounce off nearby walls and increase exposure.
10 8.2.2 Manual mode Qflash Compensation This procedure will calibrate Qflash to an incident light flash meter you use and trust. Note that only incident light measure- ments are reliable for manual exposure settings. 1. Place the Qflash 10 feet from the incident light flash meter facing Qflash.
11 5. Fire Qflash. Push the the Option ■ button, until the compensation dis play appears. 6. Use the Set G and Up J button to increase light output (if flash meter reads less than F 8.0), or the Down L button to decrease light output (if flash meter reads more than F 8.
12 9. MANUAL MODE OPERA TION The camera exposure may be set to any mode, and Qflash will emit the fixed amount of light shown on its display . 9.1 Manual Mode with sync only connection Power , F/number , ISO are all user adjustable. The Set G button will cycle through them in that order .
13 9.2 Manual mode with QTTL adapter connection With a QTTL adapter the camera controls the f/# and ISO shown on the display - you cannot change it on Qflash. The camera also selects its shut- ter speed consistent with flash exposure. The camera exposure may be set to manual, aperture or shutter priority .
14 Reminder: If the distance to the subject changes (you move in for a head shot, or move out for a full length) you must change the flash distance readout by changing the power setting. 10. AUT OMA TIC MODE OPERA TION The preferred setup for Auto Mode is to connect Qflash to a camera with a QTTL (D, Dw , or Dw-R series) Adapter .
10.2 Auto mode exposure indications There are three types of exposure indications. The display will blink either OK, Over , or Undr . The display will also indicate how much over or under the last exposure was, from +3 stops to -3 stops. If an arrow appears then the exposure error is more than 3 stops (for example -3 ).
16 Error messages will appear if you choose a fill ratio which is out of range of the flash. The error indications are: “OUT OF RANGE - DECREASE FILL OR F#” For example, the camera is set to F16 and QTTL fill flash is set to +2 stops. Either decrease the f/# on the camera or decrease the fill flash ratio on the QTTL adapter .
17 10.5 Setting the Sensor Limit: Press Option ■ button to bring up this menu. Push Set G once. The sen- sor limit will blink. Use Up J / Down L buttons to change the sensor limit.
18 10.7 Using the Sensor Limit The flash Sensor Limit function essentially cuts down on the distance that Qflash attempts to illuminate. See the examples shown below . Open field The subject is located 15 feet from the camera. The background is an open field in a park.
19 TTL Mode TTL mode may be used when the camera exposure is set to manual, aper- ture or shutter priority , or program mode, and Qflash is connected to the camera with a compatible QF series Adapter . The camera will determine flash exposure. The listing for compatible QF series TTL adapters is avail- able from your dealer , or at www .
20 12. STROBOSCOPIC MODE OPERA TION The Program mode allows you to store your favorite settings and set-ups and then quickly recall them just by pressing the Up J / Down L buttons. Program up to 8 Qflash set-ups of Manual, Auto, or TTL operation, includ- ing settings for all parameters.
21 Y our Qflash is factory preset with several Programs (which you are free to change). T o view them, press Mode I , then Up J / Down L until you see the Program mode displayed, like above. After the “P” stops blinking, press the Up J / Down L buttons to switch to the next higher , or lower program number .
22 14.1 QTTLw - Wireless TTL mode QTTLw mode gives exposure control of all Qflashes to your camera’s pre- flash evaluative TTL metering system. Both Local (on-camera) and Remote Qflashes will produce the same exposure. The Fill ratio can be adjusted on the QTTL adapter (or on the camera, if available).
14.2.2 A Local, on-camera flash is required Press Mode I , then Up J / Down L until “QTTLwR” appears in the dis- play . Y ou have the ability to turn Remote flash Group R1 or R2, ON / OFF , and the ability to set offset ratios for these groups. Note: “QTTLwR” will appear after the QTTL adapter has established communication with the camera.
24 14.3 Wireless Auto Fill Wireless Auto Fill mode has several useful features. It can add light ratio capability to non-TTL cameras. With digital cameras Auto Fill mode can decrease the delay between shutter release and image capture, compared to the camera system’s TTL control.
25 14.4 Wireless Control Mode Wireless Control mode can achieve the most control over wireless Remote Qflashes. From the camera position you can change the modes, settings, as well as the fill ratios, of Wireless Groups R1 and R2. Wireless Control mode has the disadvantage, however , of being slower to react than QTTLwR mode.
26 14.4.2 Set up the Remote Qflash Groups Any number of Remote Qflashes may be used. Set each the Mode of each Remote to either Wireless Group R1 or R2, or Linked to Local, using the Mode I and Up J / Down L controls on each Remote Qflash. The displays on the Remote Qflashes will update when the word SEND appears on the Local Qflash.
27 14.5 A vailable Modes and Features of Qflash Wireless Operation In addition to the setups described in Section 14.1, 14.2 and 14.3, other combination of modes are possible for Local and Remote Qlfashes. In the table below , pay particular attention to the models of FreeXWires and QTTL adapters required to achieve the results in the chart.
28 For independent Qflash operation the Qflashes must be in Manual, Auto (Auto Fill), or Strobo. If any one of the Qflashes is in TTL, QTTL, or Wireless, the Qflashes will no longer behave independently . Example of independent Qflash operation 14.6 SYNC only setup By employing this type of setup each Qflash operates independently of the others.
29 15. WIRED CONTROL MODE Qflash’s Wired Control Mode is a versatile tool for precise lighting control. One Qflash is designated as the “Control”, and from its panel the photog- rapher can change the modes or settings on one or two “Remote” Qflashes.
30 The displays of the two Remote Qflashes will automatically change to R1 and R2. 15.2 Select the Mode and settings for all flashes Always select the settings you desire for the Control Qflash first. Those settings determine the choices you have for the Remotes.
31 16. TYPICAL LIGHTING SITUA TIONS This section covers some typical lighting situations that photographers find themselves in. Here is how Qflash can help. 16.1 Portrait Setting up a 3:1 portrait ratio (or any other ratio) has always been time consuming.
32 16.2 Wireless lighting ratios made easy When using multiple lights to light a subject it’s very easy to set up a light- ing ratio between the Main and Fill lights.
