available for shipping ($ 6 per order) or Free store pick up. if you buy multiple cards for shipping, shipping fee is still $ 6. these sell for $ 60 at B&H, $ 65 on amazon, or sometimes even more elsewhere.

i got these because my Sony A7RII refused to write 4K to my old Samsung SDXC Pro cards, which were not UHS-I U3 rated, even though they are capable of write speed far above U3 spec. these work great. UHS-I specification indicates MINIMUM write speeds rather than maximum. this is essential for 4K video recording to avoid frame drop offs.
