Frequently Asked Questions
What microSD card format does the Ricoh GR IV use?
If you’re upgrading from a GR III, your existing SD cards will not fit in the GR IV. Ricoh has switched from full-size SD cards to the smaller microSD format. The camera supports microSD, microSDHC, and microSDXC cards with UHS-I compatibility. Based on the published specification, the size limit (max. capacity) on the microSD card should be 2TB, though cards up to 1TB are currently the practical maximum available from major manufacturers.
Do I need a fast memory card for the GR IV?
The Ricoh GR IV doesn’t need a particularly fast memory card. Ricoh officially recommends Speed Class 6 or higher for video recording. However, V30/U3 cards (30MB/s minimum sustained write speed) provide more reliable performance and are widely available at reasonable prices. There’s no need to purchase V60, V90, or high-end UHS-II cards—the camera won’t benefit from their additional speed. Because cameras interface with memory cards in specific ways, once you have a card that meets the camera’s requirements, you don’t get extra benefit by using cards with higher performance specs.
What capacity should I choose for the GR IV?
Probably the sweet spot for the GR IV, in terms of practicality and price, is around the 128GB to 512GB range, but there’s no problem going higher or lower than that. The GR IV has an internal memory of 53 GB. This provides sufficient space for approx. 3,498 JPEG images, for example. Consider your shooting style: street photographers might prefer 128-256GB for portability, while travel photographers may want 512GB or larger for extended trips without frequent file transfers.
Can I use the internal storage without a memory card?
The Ricoh GR IV Digital Camera does not support recording images to the internal storage and a memory card simultaneously. If a memory card is inserted in the camera, photos will be recorded to the card, and if there isn’t a card, photos will be recorded to the internal storage. Additionally, Ricoh has massively increased the amount of internal storage; while the GR III had around 2GB built-in, the GR IV has 53GB, which, for many users, may be enough to obviate a separate memory card.
Should I format the memory card in the camera?
Best practice is always to format memory cards in the camera where you’ll use them. This ensures the card has the correct filesystem, folder structure, and any database files the camera expects. If you insert an unformatted memory card, you’ll see an error message that “Card is not formatted” when you turn the camera on. Press the Menu button to proceed with formatting. The camera assigns the volume label “RICOH GR” to the memory card during formatting. Always backup important data before formatting, as this process will erase all existing files on the card.
Final Verdict
The Ricoh GR IV’s microSD requirement opens up excellent value opportunities compared to full-size SD cards. Professional photographers should invest in the SanDisk Extreme Pro for ultimate reliability, while enthusiasts will find the Lexar Professional 1066x offers exceptional performance per dollar. Budget-conscious users can confidently choose the Samsung EVO Select without sacrificing essential functionality. Remember, the GR IV’s UHS-I interface means expensive UHS-II cards offer no benefit—focus on proven reliability and appropriate capacity for your shooting style.
