The lens you have is a large lens, and you may not have noticed this when you purchased it. For optimal results, we recommend using it in conjunction with a small lens. Using it with a small lens like a pancake lens is particularly effective. Wide Compatibility: The Godox iM30 speedlight adopts a single-contact hot shoe design, allowing for plug-and-play use with Canon, Nikon, Sony, and Fujifilm cameras. Power: The Godox iM30 strobe is powered by two AAA batteries (sold separately), which are easy to charge and replace. Note: When used with a large lens or lens hood, the flash position may cause the light to hit the lens barrel.
