I ordered a D7000 right off the bat. It does not come with any SD cards (I believe).

For shooting video, which SD cards would be best? Size and speed?

Does brand matter?

I don't personally see differences in brand, however be real careful who you buy from on places like eBay. It's fairly common place to find cheapo Class 4 cards rebranded as expensive Sandisk Extreme cards.

On Newegg, I see a Patriot 64gb SDXC Class 10 card for $326. Two of these should be nice for video.

Sandisk extreme is good.

We do not know the write speed of the D7000 is yet so all is a guess. The D90 worked as well on Class 6 as Class 10 and brand did not make much difference other than cost. Speed might be more of an issue for the D7000 since the whole processing chain is faster.
If stills are primarily used, small or moderate card capacity is safer from losing irreplaceable images. The common practice of using big cards and loading lots of photos on them is a disaster waiting to happen. The cards fail, and they consume a little of their life span every time they are recorded to. Having 32 gig of a wedding fail would be a career impacting event, while losing one of a dozen 2 gig or half dozen 4 gig cards would be survivable. Good class 6 4gig cards are less than $10 now and being so small, having a dozen would hardly be noticed. For video, larger cards might be useful but with the same warning. Scenes ought to be kept on separate media before post production assembly.

If you are planning to shoot video, I would plan on at least 16 GB cards - and consider a 32 GB card. While Class 6 might work, I would only consider Class 10. They have been on the market for some time and there is little benefit of the Class 6 card other than price.

The big question is around the impact of SD write speed on extended camera high speed shooting. The camera produces 16.2 MB files and allows up to 6 fps. That implies processing and writing 74 MB per second to either the buffer or a memory card. With video, the largest frame size is around 2 MB, but it shoots 24 fps. That implies processing and writing 48 MB per second. Of course, both of these numbers are before compression.

The Sandisk website indicates the camera will use both Extreme and Ultra. They further recommend sizes up to 64GB in the Ultra and 32 GB in the Extreme.
http://pct1.sandisk.com/ProductList.aspx?DeviceID=16546

At this point we don't know the amount of compression in the video. The spec is H.264/MPEG-4 Advanced Video Coding. But the spec does indicate a maximum of 20 minutes of video - which is equivalent to a 32 gb card and 28 mb per second at the largest size frame, so that implies around 50% compression. If you are using a slower card (15 mb per sec), you probably will not be able to shoot for extended periods of time at the largest sized image quality.

Bottom line - my calculation is to record video at the maximum file size without filling the buffer, you need the 30 MB per second write speed of the Extreme card.

With other cards, you need to be careful about the specs. Many cards have fast read speeds but write speeds are slower. I tend to stick with Sandisk or Lexar, use large cards (16 GB), and will likely go with the Sandisk Extreme for my D7000 because of the faster write speed.

I went with a SanDisk Extreme 8GB for card one and a SanDisk Class 6 32GB for card two ... the write on the Extreme is amazing. since mine is just a hobby, I can move the best shots to the larger card and just capture on card one ... doing both Fine and Raw.

I went ahead and purchased an 8g SanDisk Extremme III for $79 this afternoon at Best Buy. Since I had a 12% coupon which by the way the offer ends tomorrow, the final cost including tax was $75. All you have to do is show him your cellular and the give them the following code #1158603 and they will honor it. I bought my D7000 kit this afternoon and they applied the 12% discount.

When I picked up my D7000 yesterday at Best Buy, I also picked up a class 10 SanDisk Extreme SDHC, 4 GB card. It will hold 271 photos on the best quality JPEG setting with 16 MP selected.

FYI - perhaps use that as a bit of a benchmark as to card size. Had I known that, ... I may have opted for an 8 GB card. Although, as many have pointed out, that's fewer photos to lose if the card is compromised somehow.

Check out Transcend's 16gb Class 10 cards for roughly $32 from Amazon.

I got one, just to test out, and it's faster (using benchmarking software) than a Sandisk Extreme Class 10. And it's much less expensive.

This past week I ordered a Transcend 16GB class 10 card and a Transcend 8GB Class 10 card from B&H. The 16GB was $25.99 and the 8GB was $17.13 (Free shipping). I'm going on vacation next week and since I don't really ever shoot raw, I plan to keep the 16GB in there all the time as a backup and will use the 8GB to download that days pictures to my ipad at the end of each day. This way I'll have 2 backups.

I was reading the comments on various class 10 16 gb cards on Newegg. So, I decided to try an unscientific experiment with the new Kingston 16 gb card I recently purchased for the D7K.

I set the camera to manual and the lens to manual. Set the burst to 6 fps. I also set the ISO to 3200, to get a high shutter speed, and went out in the back yard where I focused on the fence.

I set the burst to 6 but used single shots and pushed as fast as I could. The camera would fire about 5-6 shots in rapid succession then stop shooting, while writing to the SD. This happened over and over till I just about filled the cards. I used a 16gb shooting RAW in slot one and a 8 gb card set to shoot jpg in slot 2.

I then took the card out of the second slot and shot only RAW. I got about the same results. Five to six quick shots then you have to wait five to ten seconds to get another one or two shots in before refilling the buffer.

This is adequate for me since I rarely shoot that fast (unless it is my 3 yr old grandson). However, a sports photographer or BIF shooter might need a better (read faster) card? I noticed that many of the reviewers on Newegg criticized the off brand cards for not being as fast as older smaller cards from a major brand name.

I hope this helps someone.
