The Manfrotto Professional SD UHS-II (V90) Professional-Grade SDXC Memory Cards combine industrial strength and reliability with unparalleled performance. Designed to excel in DSLRs and advanced camcorders that require faster speeds for demanding shooting modes, the Professional SD cards safely store more without maxing out the camera’s buffer. Tougher than tough: Professional memory cards are designed to be the strongest memory cards on the market. The SD cards utilize a solid moulded design where the ‘brains’ of the card are completely sealed inside and protected, making them 3 times stronger than a regular SD card and able to withstand over 20kg of impact! Waterproof & Dustproof: SD Professional cards utilize a sealed & moulded design for protection against water damage and foreign debris, and can be fully submerged for up to 72 hours! Built for Extreme Temperatures: Whether you’re shooting in desert heat, the sub zero arctic, or you leave your memory card in a hot car, you can shoot with the assurance that Manfrotto Professional Memory Cards are built to withstand these temperature variations. SD cards are rated for temperature ranges from -25°C to 85°C.
