It features a crucial light intensity ratio control (8:1 to 1:8) between the two semi-circular flash tubes, allowing you to create subtle modeling and shadow effects, and includes conversion adapters for specific Canon macro lenses.
Achieve professional-level macro and close-up images with the Canon Macro Ring Light MR-14EX II. This unit attaches directly to the front of the lens, providing essential, shadow-free illumination needed for small subjects like insects, flowers, or product details.
The MR-14EX II features two distinct, adjustable flash tubes (left and right), allowing you to vary the light intensity ratio between them. This control is vital for adding depth and dimension to tiny subjects, moving beyond simple flat lighting.
The unit supports advanced functions like High-Speed Sync for high shutter speeds and Modeling Illumination (using the camera’s depth-of-field preview button) to preview where the light and shadows will fall. It also functions as an optical communication wireless master, capable of controlling up to 3 groups of compatible Canon slave speedlites for complex macro lighting setups. The rental includes the necessary 67 millimeter and 72 millimeter conversion adapters for popular Canon macro lenses.

A ring light provides light that encircles the lens, resulting in virtually shadow-free, flat illumination on the subject, which is essential in macro photography to reveal fine texture and detail. A standard speedlite (or bare flash) produces directional light, creating noticeable shadows.
The adapters are necessary to attach the ring light unit to the filter threads of compatible macro lenses. The rental includes the 67 millimeter adapter (for lenses like the EF100mm F2 point 8L Macro IS USM) and the 72 millimeter adapter (for the EF180mm F3 point 5L Macro USM).
While shadowless light is often desired, sometimes a small degree of dimension is needed. The ratio control allows you to make the light from one side of the ring brighter than the other (up to 8:1 difference). This creates subtle modeling, helping to reveal texture and give depth to your macro subject.
Yes, the MR-14EX II has a built-in optical communication wireless master function. This means it can be used to control other compatible Canon slave speedlites (like the 600EX II-RT or 430EX III-RT) that are placed off-camera, allowing you to incorporate background or accent lighting into your macro setup.
The rental notice advises that operation with non-Canon macro lenses is not guaranteed. While physically attaching the flash requires matching the filter thread size (using a compatible adapter, if needed), full electronic compatibility with E-TTL II/E-TTL is generally best ensured by using Canon’s macro lenses.
