This article covers ProGrade Digital CFexpress Type A モバイルカードリーダー USB-C 3.2 (PGM12)。.

Overview

The ProGrade Digital CFexpress Type A Mobile Card Reader USB-C 3.2 (PGM12) is a compact, single-slot reader designed for professional videographers and photographers who demand fast, reliable offloads in the field. Leveraging a USB 3.2 Gen 2 interface, it delivers transfer speeds up to 10Gb/s (1.25GB/s), dramatically reducing wait times when moving large 4K ProRes files or high-resolution RAW images from CFexpress Type A media. Its ultra-portable form factor and flexible USB-C cable make it easy to integrate into camera rigs, laptop bags, or even connect directly to an iPhone 15 Pro for on-the-go backups. The PGM12 is purpose-built for mobile creators who need to keep shooting without worrying about storage bottlenecks.

Product Info

Release date: 2025 (available on) Price range: Approximately ¥10,000 (as of September 2026) Warranty: 2-year manufacturer warranty In the box: USB-C to USB-C cable (~20 cm), quick-start guide * Market position: High-end professional tier. While competitors like Sony MRW-G2 offer dual-slot flexibility, the PGM12 stands out for its ultra-compact mobile-first design and seamless iPhone integration, making it the top choice for creators who prioritize portability and speed over multi-format support.

Best Use Cases

Cinema videographers: Ideal for Sony FX3, FX6, or A7S III users shooting 4K ProRes RAW. The PGM12 enables rapid card swaps and backups on set, keeping production workflows smooth. iPhone ProRes shooters: If you capture 4K ProRes 120fps on an iPhone 15 Pro, this reader lets you offload massive files directly to the phone or a laptop, freeing up space for more footage. * Traveling photographers: Lightweight and bus-powered, it fits in any camera bag pocket. Use it with a tablet or ultrabook to ingest RAW files at a coffee shop without hunting for a wall outlet.

Things to Consider

The PGM12 is strictly a CFexpress Type A reader. If you also need SD or CFexpress Type B support, consider a multi-slot reader like the Sony MRW-G2 instead. Maximum transfer speed requires a USB 3.2 Gen 2 (10Gbps) host port. Plugging into USB 3.0 (5Gbps) or USB 2.0 will significantly reduce performance. The included cable is only about 20 cm long. For desktop use, you may need a high-quality USB 3.2 Gen 2 extension cable or a powered hub. No SD card slot means you'll need a separate reader for legacy media. This is a trade-off for the compact size. ## FAQ
Q: Can I use this reader with an iPhone 15 Pro? A: Yes. Connect it directly to the iPhone's USB-C port, and the Files app will recognize the CFexpress Type A card. You can copy photos and videos to the phone's internal storage. Note that some RAW video formats may not play back natively on iOS. Q: How do I achieve the full 10Gb/s speed on Windows? A: Ensure your PC has a USB 3.2 Gen 2 (10Gbps) port, typically marked with a 'SS10' or '10Gbps' label. Using a USB 3.0 (5Gbps) port will cap speeds at around 500MB/s. A USB 3.2 Gen 2 expansion card is recommended for older desktops. Q: Can I use a longer USB-C cable? A: Yes, any USB 3.2 Gen 2 certified USB-C cable will work. However, cables longer than 1 meter may introduce signal degradation and reduce speed. Stick to high-quality, 10Gbps-rated cables for best results.
