SDXC card question for 7D mkii

I see that B&H has the cards on sale.

Do you think these would be sufficient for use in my 7D mkii? I never shoot video. When using high speed continuous mode, I have it set at 8FPS but seldom ever shoot over 5 frames in a burst. I have it set to save both the highest resolution RAW and JPEG files at the same time. I would think these cards would be fine but thought I'd ask.
Thanks.

Let the manual be your guide...page 5

I know,technically the card is accepted, I'm just wondering if the read and write speeds would be sufficient as there are much faster cards available but I don't want to spend extra money if it'll be of no advantage for my shooting style.

The very best (read that as fast) of the SDXC cards almost does as well as the very best of the CF cards. A comparison, with specific cards and readers, can be found at http://www.nine-volt.com …aster-youll-be-surprised/.

Hi,

I went through the same thing earlier this year after getting my 7DmkII, and I have to second all the responses pointing you in the direction of careful research. That's exactly what I had to do, for just like you, I wanted to make absolutely sure of a scenario I didn't anticipate needing the maximum speed for (i.e.: shooting lots of video).

In the meantime, I just used a card that was provided at that time with my new 7DmkII that I purchased from Canon directly. (the promo included a free SECOND battery, AND an SanDisk Ultra 32GB SDHC I card. It was a Class 10 with a write speed of "just" 30MB/s). The one you have in question is the same model, but writes at up to 80MB/s . . . much faster write speed.

1. I had zero problems with write speed, and I shoot a lot of bird images . . . then again, the 7DmkII doesn't have a huge buffer so eventually it will slow down and crawl, so the faster the better, IMHO.

2. Now if you were shooting a bunch of video too? Sure, go with the expensive cards rated U3 for writing the Ultra speed information faster like you need in video.

AFTER MY RESEARCH, WHAT I ENDED UP BUYING . . .

The following card received the very top rating in one exhaustive report of various cards, so I bought it. I will probably buy another one two.

SanDisk Extreme Pro 95MB/s SCHC 1, U3 Class 10. Best of all, it holds a whopping 128GB of image files. Frankly, you can never have too much file size when you are in the field! Too many times in the past I've had to manually go through and delete images when my camera card got full. It is like having a car with a 300 gallon gas tank. Those cards have dropped down to less than $80 now on the link you provided. A lot of money, but they've come down a lot since I bought mine.

Yes, it does give that extra performance when shooting video. The 7DmkII is a wonderful video camera with lots of capability, but ya gotta have the fast cards for the new high def video to do best. Why not get what you need . . . if it is in your budget of course.


TWO OTHERS TO PONDER . . .
1. Immediately below the one you are looking at now is the same high performance card I own, performance-wise AND it has TWICE the file size as the one you mentioned, at $24.95 It is the 32GB SanDisk Extreme Pro 95MB/s SCHC 1, U3 Class 10 . . . a great, high performance card which will hold a decent amount of images, especially since you are shooting RAW + JPG! You'll fill up a 16GB card pretty fast shooting at a high fps.

2. Also to consider, the SanDisk 32GB Extreme UHS-I U3 SDHC Memory Card (Class 10). It has the same basic performance of the Extreme Pro, thus a good choice if you shoot some video . . . and I bet you will!

Hope this helps!

Thanks for the info. everyone. I did end up ordering the cards I posted above. The price is great and since I don't shoot video I'm sure these will work just fine. Hairyjames, these are a 64gb card, not the 16gb like you had mentioned.

Now I need to buy a card reader that accepts these cards. Not real impressed with the reviews for the Sandisk model. Anybody have any recommendations?

Just a headup, Sandisk Ultra SD does NOT write at 30MB/s. that is "transfer speed", usually referred to read speed. Sandisk Ultra, as of Jan 2016 production, write at about 10-12MB/s. It is not meant to be high performance card. It is the minimum spec card to meet Class10.

Incorrect statement.

Sandisk Extreme grade can write at about 45MB/s for sequential data. Extreme pro card can write at 95MB/s. So no, they are not the same at all. In fact, 32GB Extreme use MLC(2bit/cell) nand. 32GB extreme pro use SLC (1bit/cell). More than then speed differences, SLC is a lot more reliable.

Having that said, most people don't need the speed of 95MB/s in camera, not the reliability of SLC for SD card. So I do think Extreme line represent the best compromised between cost and performance.

I use this for my SD cards.

Cheap, fast, and I have had zero issues.

I originally used some older cards I had lying around (Lexar Pro 400X SD and Sandisk Ultra CF) and was not impressed with either. I then followed their recommendations for both SD & CF cards in the above link and and very impressed with the performance of both.
