After looking at all the different memory cards I decided to buy a 2pk which I was so thankful the other night when I went threw one card & had another one ready to go. The memory card is fast my images get onto my LCD screen in a blink of an eye. I'm considering buying another pk just to have on hand. The price was good too. I've looked other places & to buy 2 separate cards it would cost my more money. I'm using this with my 5D Mark3

I'm a professional photog shooting lots of fast action. I purchased this bundle last september from B&H, because i've been using previously Lexar's 300x speed cards and i never had any trouble with them. Now these 400x speed cards were fine for few months, then file corruptions started to roll in. Pretty much every time i had between 5-10 corrupted files in a card, no matter if i shot 100 or 400 frames into it. I shoot mainly surfing from water and it really svcks if the money shot in a seq has pink/green/white stripes all over it. Corrupted files also come in pairs most of the times, first one being half destroyed and second completely empty. I've done disk utility's 35 pass erase many times over, but it doesn't help. I shoot with two D3, and since corruption issues begun, i've been using the old 300x cards and all the issues went away.

Lexar media = confidence. I've learned not to trust any other CF media in my pro-body Nikons. Nothing keeps up with the transfer speeds of my D2xs and D4 better (except XQD), and nothing is more reliable. I've never gotten a "bad card" error using Lexar media. Sure it costs more, but how much does losing a card full of images cost you?

I shoot with a Canon 5d Mark II. I get 600 shots with this card shooting RAW. I've used Lexar cards for 7 years and have never had a problem with any of them.

I guess Lexar would be most valuable investment one makes to store the images. The card is a power pack with read and write speed. After using a bunch of them already, I started recommending them to friends. Planning to update my wife's camera to Lexar by Christmas.
B&H is awesome too. I just ordered in time before the deal got over, but B&H closed for holiday season already. I was informed my card would ship after they reopen. They were awesome to ship it earlier and I got it the same week.

This card has got to be great for use in the revolutionary D4 for many reasons. Thus far it has been. Because of my photographic arena, which is ecology here and abroad, I must purchase products that promise superb and long-lasting results. This card is very easy to use and reacts swiftly to any request. I have found nothing that I am unsatisfied with.

I just finished a shoot where 20% of the images were corrupted. I purchased this card in a two pack about 6 months ago and never had a problem until now. Unfortunately I no longer trust them. I've only had two cards go bad in my life and they both have been Lexar. I never thought the brand mattered too much as long as you purchased a higher end card. I no longer believe this to be true. I've owned a lot of San Disc and that's what I'm sticking with.

Lexar has always been reliable for me. When my local camera store sold me Transcend cards (against my better judgment) and they failed on a few different times, also would not reformat at full 16gb capacity only at 7gb capacity, I kicked myself all the way to B&H to buy these cards.
So far so good. Always reliable, I've never had one fail. They reformat at 16gb on my Canon 5dMarkII and are fast. They export to my computer and editing software really fast as well. I'm very happy

Comments about Lexar 16GB CompactFlash Memory Card Professional 400x UDMA - 2 Pack:
Bought this combo pack last year and after my second use in a new canon mark iv one of the cards became corrupt and I was unable to recover about a third of the images even after running several software programs. Did hard reformat and gave it a second shot but same thing. Wrote bad on the card and threw it in a drawer. The other card still works but fails to mount when inserted in a cf reader until it is removed and re-inserted several times. I've only had two CF cards completely corrupt in my career and they were both Lexar. One was a very expensive 1 gig card i bought years ago and this one. This incident solidified my loyalty to SanDisk.

Comments about Lexar 16GB CompactFlash Memory Card Professional 400x UDMA - 2 Pack:
I shoot Canon 7D, 5D II, and 1D III cameras. When I first began using these cards they were great. Periodically I would get an image or two with an unsupported file format but I attributed that to my cameras or not formatting the cards when I should have. Well, now I get the error consistently. I have since had all of my equipment serviced by Canon Professional Services and just shot about 1000 pictures with these cards, 1 in the new Canon 1D X. Over 1/2 of the images were unreadable by my computer. I had to use the recovery program to recover the file format. I am now working to make a claim on the warranty.

I have nothing against the brand or the card itself, but I just bought a 5D Mark II and from what I found, these were going to work great! But I have found several times already that I'm waiting for the camera to 'write'. I've missed some good shots due to the delay. So while I would still recommend the cards, keep in mind they may be too slow for your needs. FYI- I was shooting portait sessions.

As title. The speed is fast enough to buff up the D3, even files like a 32min exposure or enough 64min. Upload speed is around 12mb/s, but the computer and the card reader can factor into that too.
