Question: Anyone use the 64GB memory cards?  Any issues?  I use the 32GB cards with my D7000...
Document: How about 64 of those "really AWESOME"  (when they came out) 1gb cards?! I can't even get my head around putting 2ea 64GB cards in there...but I COULD - but thats just nuts...even if 2ea 32GB isn't?
I got two 32GB cards which is still a ton of memory.I will try to get out to a local lake tomorrow and take some herp and bird pics and post the results.First impressions, I really see a ton of potential in this camera and I am excited to see what it can do. Especially when my other lenses come in. By the way, the other lenses are the 85mm micro and the 55-300mm.
Almost all where usable though (most viewers wouldn't even notice).- easy access and control of settings through menus, buttons and programable buttons you can choose functions for (sadly you cant apply ANY function but you have a choice of some). Nikon has always done well here.- SD card memory 2 SLOTS!? SO LONG compact flash...I disliked you for such a long time! And now I've got 2ea 32GB cards...its like carrying a whole film store's worth of film.
When I take three shots in a row, it takes eight seconds for the first image to show up on the screen. This takes less than a second on my old 12Mp D90 or my friends D7000 -- same memory cards (all class 10), same lenses, same everything else. Since I usually check the back of the camera to see if the shot turned out, this extra wait time is a deal-killer.
I do expect to buy another battery at some point for times when I might be taking a couple thousand shots over a weekend.Memory Card:I enjoy being able to put two SD cards in here and plan to always use them in the backup mode (in case one should sheet the bed). VERY IMPORTANT, BIG DEAL HERE:  The memory you put in is very important. From my D5100 I had a fewTranscend 16 GB Class 6 SDHC Flash Memory Card TS16GSDHC6E.
I feel like a boss when I use it. A boss that laughs at your Canon 5D or Nikon 3100!It's got 2 SD slots! Dual SD-cards mean that I can shoot and shoot and shoot and shoot... and never need another SD card. 2 64GB SD cards loaded? This might indicate why I have a mild drinking problem. Have you ever sat through post processing on 3,479 f***ing photos???
You can also shot a 3 frame bracket shot if you want also. The DOF is also much easy to use than on the D7000. The D7100 is just a better camera and much easier to use, keep the D7000 as the back up camera. Given these two camera you are ready to take on the journey of taking much better picture, where ever to want to shot. I strongly recommend the purchase of this camera to anyone that wants to improve their pictures and the experience of taking pictures.
Nikon's 24 mp DX format CMOS sensor in the D7100 avoids the use of a low pass filter and thus improves sharpness (with proper technique) with "usable" (subjective term I rarely shoot beyond ISO 200) ISO to 6400 with perceptible noise issues beginning to develop around ISO 1600. There are significant improvements to focusing and speed processing through the use of a 51 point focus system and Expeed 3 processing (2016-pixel RGB evaluative sensor)- a significant improvement over the D7000 (many reported focusing speed issues).
Item description clearly states that this camera will be shipped with a FREE camera bag and 32GB SDHC card. Neither were included in my shipment. Will return the camera on Monday when the shipping store opens.Direct quote from product description. "Purchase this camera and receive a free 32 GB memory card and bag, and save hundreds on select Nikon lenses and speedlights. "Amazon replied within a couple of hours and compensated for the missing items with a refund.
I was looking to upgrade from my D70 and this is the perfect upgrade. I did need to get new memory cards but the lenses and flash that fit the D70 fir the D7100. It takes unbelievably crisp pictures...wonderful camera, easy to operate.
Answer: Keep in mind if you use a large memory card and something (gulp) happens to it (like losing it, damaging it, having it stolen, etc.) your data is ... gone.  For this reason, consider using smaller cards and store them relatively quickly.  One of my memory cards turned up missing after a shakedown at an airport in India and all I can say is I'm glad I had another one with half my photos.
