The control unit
Firstly, the control unit has a great contrast adjustable LCD panel which provides an instant view of your settings. You can choose between green or orange background of the LCD panel.
Using this ring flash, you can of course benefit from the ETTL feature to expose your photos automatically. If you don’t like to use the ETTL mode, you can also switch to the normal manual mode to get full control.
Just beneath the LCD screen, you will find four buttons. With these buttons, you will get some great extra features I will show you right now:
C.Fn-button: With this button you can set up to 12 custom functions (like auto power off, test firing, focusing lamp, etc.) with 27 options. Additionally, you can create 3 individual functions like the brightness of the focusing lamp, contrast of the LCD display or the color of the LCD panel.
+/- – button: In combination with the “Select dial”, you can adjust the flash exposure compensation up to 3 stops in 1/3 stop increments
FEB – button: This abbreviation stands for “Flash Exposure Bracketing”. With it you can make great HDR photos by taking three photos with different light strength
SYNC – button: this is my favorite feature. Actually, SYNC means high-speed synchronization. With this, you can shoot at very high shutter speeds. For with a normal flash, you can shoot usually at shutter speeds of 160 up to 180, depending on the manufacturer. With those shutter speeds, it would be pretty hard to unpossible shooting subjects which are moving fast, e.g. insects. Take a look at the pic below, folks. Here I used the SYNC function and was able to shoot the two insects in the left side and freeze them sharply in the photo.
Control the flash tubes separately with the ratio button
When you press the radio button, you will be able to control the each of the both flash tubes separately which are named tube “A” and tube “B”. This allows you to expose parts of photos where only one side needs to be made brighter. It’s also possible to let both tubes to flash at different individual power.
Using the ratio button you will also see, that there is even a third tube controllable (letter “C” on the display). As the Canon ring flash MR-14EX II has two tubes, it becomes obvious that the “C” stands for a third flash which can be used remotely. With this feature you can not only expose the subject but also make the background brighter when you use a third flash remotely.
Power consumption of the ring flash and recycle time range
The MR-14EX has a full recycle time between 0.1 to 5.5 seconds, depending on how much power is remaining in the capacitor. This leads us to the next great function of this ring flash, the so-called quick flash function. It allows you to fire the flash before the capacitor is completely charged again. The range of the quick flash cycle is about 0.1 to 3.3 seconds.
This Canon ring flash is powered by four AA batteries*. Depending on the light intensity you use during your shoots, you would be able to get between 100 and 700 flashes (used with 1900mAh batteries). Another useful feature is the external power supply which makes the work with this device once more professional.
