LENS USABILITY

Although this Flash is designed specifically for Macro lenses (MACRO 50mm F2.8 EX DG, MACRO 105mm F2.8 EX DG, etc.) it is also possible to use it with other lens types, however please pay attention to the following points.

Front part or other parts of some lenses rotate while focusing, and also attaching the ring flash to such

lenses would affect focusing mechanism of your camera, possibly resulting in malfunction. Please use Manual Focus only with such lenses.

Ø55mm, and Ø58mm filter MacroFlash Adapters are bundled with your flashgun. If you want to attach your flashgun to a lens which has a different filter size then please purchase separately a MacroFlash Adapter.Only Ø62mm, Ø72mm, Ø77mm macroflash adapters are available.

Depending on the lens’ focal length or the distance to subject or another reason, it is possible that your image might be affected by vignetting. Please take some test shoots first to be sure that your setting is not causing vignetting.

CAMERA MODELS AND FUNCTIONS

Although this Flash unit has been equipped with numerous functions, depending on the camera model being used some functions may have some limitations. Please confirm the type camera you have from the list below. Please refer to explanations of each function through the instruction manual; If no model information is specified, it means that this function of flash can be used with all type of EOS cameras.

A type camera

E-TTL, E-TTL II compatible cameras

B type camera

All other EOS cameras except those listed above

ABOUT THE BATTERY

This flash unit uses four “AA” type Alkaline dry cell batteries or Ni-Cad, Ni-MH, rechargeable batteries. Manganese batteries can also be used but as they have a shorter life than Alkaline batteries, we do not recommend using them. Please replace batteries if it takes more than 30seconds to light the Ready Lamp.

To assure proper electrical contact, clean the battery terminals before installing the batteries

NiCad batteries do not have standardized contacts. If you use NiCad batteries, please confirm that the battery contacts touch the battery compartment properly.

To prevent battery explosion, leakage or overheating, use four new AA batteries of the same type and brand. Do not mix the type or new and used batteries.

Do not disassemble or short-circuit batteries, or expose them fire or water; they may explode. Also, do not recharge the batteries other than Ni-Cd rechargeable batteries.

When the flash will not be used for an extended period of time, remove the batteries from the flash, to avoid the possibility of damage from leakage.

Battery performance decreases at low temperatures. Keep batteries insulated when using the flash in cold weather. As with any flash, it is recommended you carry spare batteries when on a long trip, or when photographing outdoors in cold weather.
