Best Memory Cards for Ricoh GR IV

The Ricoh GR IV, often hailed as “the ultimate snap shooter”, is the newest addition to Ricoh’s celebrated GR line. Known for its compact body and uncompromising image quality, the GR IV elevates the experience of everyday photography. With a redesigned 28mm-equivalent lens, a 25.7MP BSI CMOS sensor, and improved autofocus paired with Shake Reduction, it’s a powerful tool wrapped in a pocketable form factor. Add to that an upgraded battery, more internal memory, and the GR WORLD app for wireless image transfer and control, and you get a camera that blends tradition with innovation.
But despite these advancements, one technical detail requires careful attention: the GR IV uses a single microSD card slot limited to UHS-I microSD cards. This makes choosing the right memory card essential for ensuring fast buffering, seamless 4K recording, and long-term reliability.
Not all microSD cards are created equal—some prioritize speed, others durability, and some strike the balance of value and performance. In this guide, we’ll walk through the best memory cards for the Ricoh GR IV, breaking down their specifications, performance, and practical applications. Whether you’re a professional street photographer, a content creator, or an adventurous traveler, this list will help you find the perfect match for your shooting style.
