The world of compact flashes just got even more interesting with the release of the Godox iM20. If you're familiar with Godox's recent lineup, you'll know they've been focused on producing small yet powerful flashes that complement compact and mirrorless cameras, particularly those without a built-in pop-up flash. The iM20 is the latest addition to this growing range, offering an ultra-compact and lightweight option for photographers on the go.
Unboxing the Godox iM20
Right out of the box, the first thing you'll notice is just how small the iM20 is. Sitting comfortably in the palm of your hand, this flash is designed for minimalism and portability. It comes with a soft pouch, which features subtle Godox branding and a velvet-like material, making it easy to carry and store. Alongside the flash, you'll find a USB Type-A to Type-C charging cable and a user manual.
Design and Build
The Godox iM20 is even smaller than its predecessor, the iM30, making it a fantastic alternative for those looking for an ultra-compact flash. Weighing just 31g and measuring approximately 39x38x29.5mm, it seamlessly blends into the design of smaller cameras like the Sony Alpha series or the Fuji X Series. The hot shoe mount is a single-pin universal connection, meaning it’s compatible with most cameras that feature a standard hot shoe.
Unlike the iM30, which runs on AAA batteries, the iM20 features a built-in lithium-ion battery. This is a huge advantage in terms of both convenience and performance. The 470mAh battery allows for approximately 440 full-power flashes before needing a recharge, and it takes just about an hour and ten minutes to reach full charge.
Performance and Features
While the iM20 may be small, it still provides useful functionality for photographers who need an additional light source in low-light situations. It offers five steps of output control, easily adjustable via the plus and minus buttons on the back. The LED indicator lights up green to show the power level and blinks when recycling. Speaking of recycle times, at full power, it takes around three seconds to be ready for the next shot—while not the fastest, it’s reasonable given the size and intended use of the flash.
This flash is best suited for casual or travel photography rather than high-speed event shooting. Its directional lighting can be useful for close-up portraits, product photography, or adding a bit of fill light in darker environments. If you want to soften the light, a simple DIY diffuser—such as a thin sheet of diffusion material—can be taped over the front.
Comparison with the Godox iM30
For those trying to decide between the iM20 and iM30, here’s a quick comparison:
-
Size: The iM20 is about a third of the size of the iM30, making it even more portable.
-
Battery: The iM20 uses a built-in rechargeable lithium-ion battery, whereas the iM30 requires AAA batteries.
-
Output Control: The iM30 offers more control over output levels and features slave functionality and an optical sensor, while the iM20 keeps things simple.
-
Hot Shoe Design: The iM30 has a locking mechanism, whereas the iM20 has a streamlined slide-in mount.
Final Thoughts
The Godox iM20 is a great addition for photographers who want a discreet and lightweight flash for their mirrorless cameras. It’s easy to use, has a decent battery life, and is perfect for everyday photography where a small pop of light is needed. If you require more control over output and additional features, the iM30 might be the better choice, but for ultra-compact usability, the iM20 is hard to beat.
For those who want a reliable, travel-friendly flash that doesn’t weigh down their camera setup, the Godox iM20 is an excellent choice. Whether you're shooting street photography, casual portraits, or simply need a small light in a pinch, this tiny powerhouse gets the job done effortlessly.
