1 2 3QuickGuide to Macro SpeedliteMR-14EX and MT-24EXThis QuickGuide reviews how to use either of Canon’stwo Macro Speedlites: the MR-14EX and MT-24EX. Theprimary difference is between them is that the MR-14EXhas two circular flash tubes permanently mounted oppositeeach other onto the Flash Ring, while the MT-24EX hastwo removable and adjustable flash heads that snap intominiature flash shoes.Control Layout1. LCD ILLUMINATOR/C.Fn – LCD illuminator/CustomFunction button2. MODE – Flash mode button. Toggles between ETTL/TTL and M (manual) flash mode.3. + : Increase button. Increases flash exposurecompensation. Press SEL/SET first.4. − : Decrease button. Applies “minus” flash exposurecompensation. Press SEL/SET first.5. SEL/SET – Select/Set button. For selecting andsetting features and functions.6. LAMP – Focusing lamp button7. ◄ - Left arrow button. Increases power to left flashtube (A) relative to right (B).8. ►- Right arrow button. Increases power to right flashtube (B) relative to left (A).9. RATIO – Flash ratio button. Cycles ratio between OFF,A:B, and A:B C. When A is displayed in Manual flashmode, the flash output displayed (1/1 thru 1/64) isfor flash tube A. When B is displayed in Manual flashmode, the flash output displayed is for flash tube B.10. CH - Channel button. Selects flash channel (1 – 4)when unit is in wireless slave mode.11. PILOT – Pilot lamp and test fire button12. Flash Exposure Confirmation lamp13. Power switch –Turns power on and off. SE positionenables “Save Energy” mode, which automaticallypowers down the flash after 90 seconds of inactivity.To cancel SE mode, press the PILOT button.Attaching/Detaching the Flash RingThe Flash Ring attaches directly to the following lenses:• EF 50mm f/2.5 Compact Macro• EF 100mm f/2.8 Macro USM• EF 100mm f/2.8 Macro (now discontinued)• MP-E 65mm f/2.8 1-5xThe EF 100mm f/2.8L IS Macro requires Macro LiteAdapter 67C. The EF 180mm f/3.5L Macro requiresMacro Lite Adapter 72C (each sold separately). MacroLite adapters are available in sizes 52mm, 58mm, 67mmand 72mm.To attach the Flash Ring, press in on the releasebutton(s) while placing the ring onto the lens. When thering is in place, let go of the button(s). Make sure thering is firmly attached. To detach the ring, reverse theprocedure.Selecting camera exposure modeSet your camera to whatever exposure mode you prefer:P, Av, Tv, or M. Choose Manual mode when you wantsmall apertures for maximum depth-of-field combinedwith a fast shutter speed to help minimize blur andseparate the subject from the background. (Light fallsoff more rapidly at short distances, therefore the closerthe flash is to the subject, the darker the backgroundexposure will be unless you either increase the shutterspeed/ambient light exposure or light the backgroundseparately.)E-TTL OPERATIONBasic E-TTL Auto operationWhen the flash unit is set to E-TTL it will automaticallyemit a brief pre-flash prior to the actual flash exposure.Based on the pre-flash measurement, it will then adjustthe flash duration to provide proper exposure basedon a combination of flash-to-subject distance, subjectreflectivity, aperture, shutter speed, and ISO. This appliesto all camera exposure modes, including Manual. Pressthe MODE button to toggle between E-TTL and M. Theflash is in E-TTL mode when ETTL appears in the upperleft corner of the LCD.To operate the flash in E-TTL mode:1. Turn the power switch to ON or SE.2. Set the camera to the ISO and exposure mode ofyour choice. If the camera is set to Auto ISO, the ISOsetting will vary as follows:Tv or Av or P or CA or Full Auto: The camera willautomatically set the ISO speed at 400 (or 800 onRebel T3).Av Fill-in Flash: If the pre-flash detects over-exposure at ISO 400 (or 800), the camera will reducethe ISO to as low as 100.P or CA or Full Auto & bounce flash: If the pre-flash detects under-exposure at ISO 400 (or 800),the camera will increase the ISO speed to as high as1600.3. Focus and release the shutter.4. If there was enough light for a correct exposurethe green Flash Exposure Confirmation Lamp willilluminate for 3 seconds. If not, the lamp will notilluminate.E-TTL Flash Ratio ControlBecause the MR-14EX and MT-24EX have two flash tubes(A and B) you have the option of firing A and B at equaloutput (1:1), firing A and B at an unequal ratio (1:2, 1:4, 2:1,etc.), or firing either A or B independently.Equal output1. Press the RATIO button once. The ratio display willappear.2. Confirm that the ratio indicator is in the center, below1:1. If not, press either the ◄ or ► arrow as neededto move the bar back to the center.A:B ratio1. Press the RATIO button once. The ratio display willappear.2. Press the ◄ arrow toward flash A (left) to increaseits power. Press the ► arrow to increase power offlash B (right). Each press will increase the ratio by ahalf-stop. An A:B ratio of 2:1 indicates that flash A willoutput twice as much light (one stop) as B. A ratio of4:1 indicates four times as much (two stops). A ratio of8:1 indicates eight times as much (3 stops).
