In contrast to normal external flashes which consisting as a single part, the ring flash consists of two parts. The first part is the control unit which you put on the top of the camera by sliding it into the flash hot shoe, and fixing it with a lever. The second part is the flash unit which you need to clip onto the end of the macro lens (or any other lens). Some lenses (like Canon’s 100mm Macro Lens* or the 180mm lens) require adapters, because the lenses have different diameters.
These two parts are connected together with a coiled cord.
The flash part
The flash itself consists of two flash units which can be controlled separately (if needed). A great feature are the two assist lamps on the flash. Turning them on, you would be able to enlighten the subject for 20 seconds for focusing purposes. After 20 seconds the lights turn automatically off.
The control unit of the Canon ring flash
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.
I introduced to you the main functions and features of the Canon Macro Ring Lite MR-14EX II. Below you will find a list with more functions and advantages this device will provide you
With the Canon ring flash MR-14EX II you will get a professional and excellent product. But here I say the same I said in my article about the Canon 100mm macro lens: if you an absolute beginner, you maybe should by a cheaper ring flash (e.g. from Yongnuo), as Canon’s one has it’s price. Of course, if money plays a minor role, you will not be disappointed by purchasing this ring flash with a lot of useful functions. The picture quality is great (presumed, you know how to use this gear), the high-sync function makes you addicted to shooting pics of insects, and the exposure bracketing will provide you a chance to make great HDR photos.
