Best SD memory cards for Sony a7R IV mirrorless camera. Here is the guide for you to get the top recommended & fastest SD cards for Sony a7R IV.
The new Sony a7R IV mirrorless camera has two memory card slots that both support the ultra-fast UHS-II SD cards. This will allow you to maintain great speeds while still recording backup to a second card, and you should spend a little more money to get a UHS-II card if you want the fastest possible results. Featuring a 61MP Full-Frame Exmor R BSI CMOS Sensor and enhanced BIONZ X image processor, the Sony a7R IV can offer impressively high-resolution stills and video while minimizing noise, improving speed, and achieving a wide 15-stop dynamic range. In addition, the Sony a7R IV enables internal UHD 4K30p video recording with a wide 14-stop dynamic range, and it avails fast continuous shooting at up to 10 fps at full resolution with full-time AF/AE.
Simply put, the Sony a7R IV (Amazon, B&H, Adorama) is an ideal mirrorless camera for enthusiasts, hobbyists and professionals alike. So, in order to get the best out of the Sony a7R IV camera, some fast enough and reliable SD memory cards are your best choice. Since the Sony a7R IV takes UHS-II memory cards in both slots, we recommend using dual UHS-II memory cards.
