Nikon XQD 64GB High-Speed Memory Card for Professional Photography & 4K Video - Compatible with Nikon D5, D850, Z Series Cameras - Perfect for Sports, Wildlife & Action Shots

Bought for backup in my Nikon and very happy. Its fast and a very neat format. Not a popular format but I can see why Nikon thought it might be its chunky well made and easier to carry and use than a normal CF card so should be far more popular but the price does not support mass take up of this medium which seems a shame its otherwise perfect.I haven't had these cards for long, and I rotate them out so not a ton of use, but less than year later and I'm getting red X marks in some spots where there should be photos when reviewing on the back. Not sure if this is a common problem? It's only happened with one of my cards so far. A little disappointed that I can't use this anymore for work with how expensive they are.Bought the wrong card for my camera. Can't return or trade for the right one.So far the product has worked fine.Received what I paid for.Great productFirst time using. Not sureI needed a bigger memory card as I was shooting in 4K and the 32 GB card that came with the Nikon Z6 was filling up quite fast. The card works well and transfer speeds are as claimed. First time noticing a Nikon XQD card, but it worked without a hitch.Fast as expected. Camera processing gone fast but best part is transferring images to laptop...it is super fast now...La transferencia de de datos en mucho más rápida que con una tarjeta SD. Funciona muy bienVery fast ..reliable ..durableGood quality and reliable.Good delivery by Amazon
