Does what it's supposed to do

Lexar cards are supremely high quality cards. This card is super high speed, and writes fast. Can't ask for more than that.

Awesome solid card!


from Northern CA  -  Professional

Awesome solid card! Love Lexar, however do not have a strong preference between SanDisk or Lexar, Both are fine for me.


Perfect no issues


from Northern CA  -  Professional

Love using 64 GB card. Pretty much entire wedding fits in one card. Oh yes I do use 2 cards when I shoot 1SD card and backup CF card. No issues so far, very solid

does not work with Nikon D4


from seattle, wa  -  Hobbyist/Enthusiast

The card does not work with my Nikon D4


FINALLY, an easier way to shoot!


from Austin, TX  -  Professional

This is the best purchase I've made in a long time! Instead of fumbling with a handful of smaller cards, now I can just shoot to dual slot CF cards that are backing each other up. Seemingly fast enough for a fast paced wedding day!


fast reliable and sturdy


from NY, NY  -  Hobbyist/Enthusiast

I already own 5 of these cards and have used them in Asia, Central America and home. They have never failed me, wrote fast and withstood abuse. I will buy more.


Great Product at the Right Capacity


from San Francisco  -  Professional

I shoot many weddings in large, RAW format. The 32Gb capacity CF cards were nice but had to be replaced to get through a long day. With multiple cameras, that only complicated the problem exponentially. The 64Gb card is the right capacity and the download speed from the card to the computer is faster. Just what I needed.


Buffer beaters!


from NYC Metro Area  -  Professional

I have bought SanDisk for years, but had to try the Lexar 1000x cards when they came out. For buffer-clogging work, these monster cards are not only huge, but fast! No issues in-camera, and no hiccups dumping to the computer. Really, is there anything else you can reasonably ask of a CF card?


Fast and reliable


from Wisconsin  -  Professional

I've tried several brands of CF cards over the years, but find Lexar to be the best in reliability. I shoot a lot of all day weddings with a Nikon D800 and D700, so I need something that is not only fast, but that I can trust.

Questions about this item:

Shopper  Why Did You Choose This?
DONALD H  I just bought a super-fast camera, D800, I didn't want to cut corners on half-fast memory. I just tested this card in my new D800 that came this afternoon and I can say for certain that it is much faster writing/reading than my 600X card. I only costs a little bit more when you buy it, but when you use it every day like I do, it pays for itself in time saved in a big way. Don't worry about the couple extra dollars. Buy this card and don't look back. I love mine.
Shopper  Will this card work on a Canon 1 d Mark 11?
PHIL S  According to Lexar it should work. See this webpage: lexar(dotcom)/support/cf-professional-faqs#faq-4 Use .com instead of what I wrote above to get to the site. Adorama doesn't allow referral to webpages.
