When I have made a shot it takes several seconds before the camera are ready for a new shot. There is a green light flashing. I have an idea of it could be some automatic noise reduction the camera made. I do not know if it is right and if it is - where can I shot this option off
Thanks for your quick reply - but I am afraid this not solve my problem I have "Long Exposure" turned off. Anyway - I have as a new user go through the manual to learn the camera. But thanks for your answer anyway
I would say that it has to be something about the writing speed from the buffer to the SD card. It also could be that the camera is processing the image. Try to shoot jpeg with lowest quality. If this still happens then it is something about the SD card.
The Green Memory Activity light flashing occurs when writing to the card. If transfers are taking several seconds, even when the buffer is empty, it means the card is really slow in accepting data. The D7100's 24mpx files are very large and demand fast cards, it is moving a lot of data compared to the lower resolution cameras.
Get at least one fast card to test it with. Be aware that some discounted cards are not what the label claims, counterfeit cards, where much less valuable slower cards are relabeled to sell for $20-50 more. A 6-10mpx camera would never notice a Class 4 card labeled as a Class 10 but that would cause your camera to slow to a crawl. Stan St Petersburg Russia

You are right Franklin43 - I am also learning new every day. But you see, when I bought the two cards together with the camera, I bought it from a proffesionel camera shop. An the clerk told me that these cards were some of the best ! Morale : Do not trust on the sellers - or what !
The shop (shoppe) that I purchase my equipment from is run by pros that also teach classes on various types of photography. They show you how to use your purchase and test it to make sure it works well before you leave. If you prefer not to "test" your purchase there they have a 15 day return policy. What amazes me is that they match legitimate on line prices. I have dealt with the top on-line sellers in the past and have never had a problem. The only "misrepresentation" I encountered was on a "great" card buy from a seller that I did not know and an on-line bate and switch company.
The cost and time of sending the cards back...I just used them in my wife's point and shoot. The camera equipment; I caught the "misrepresentation" in time, after a few telephone calls to Visa, the conman and checking with the fraud division of the State of California...I got a full refund from closeoutdigital.com. I would not, under any circumstances, buy anything from Closeout Digital.
Now; it is either my local store, eBay or the "good" on-line sellers. If, in fact, you did get a mislabeled card the seller should be willing to exchange it for the correct one and deal with whom ever sold it to them. If it is just to "slow" and you relied on their advice, they should also be willing to make the exchange. If not, I would never deal with them again.
I think the lesson learned has nothing to do with the general honesty or lack of knowledge of any particular store retailer than it does with consumers (that's us) learning about the rated write speed of a specific SD or CF card being considered. As Stan mentioned, a 24mp DX camera writes big NEF files to the card, so it makes sense that an SD card rated for 45MB per second write speed is usually the minimum that should be considered. Slightely slower cards (e.g., 30MB per second write speed) can also work well as long as they're in the faster class of cards.
Also . . . stop listening to retailers and anecdotal information about what SD cards work best. Instead, go to the SanDisk, Lexar and Integral web sites and read their ratings. Go to the Rob Galbraith card comparison database (which is still relatively current) to compare various brands and models of cards and to get an objective reading of the differences between different classes and types of cards.
For what it's worth, since moving up to the D7100 and D800, I use only SanDisk Extreme Pro SD and CF cards. Best speed and reliability for the money, IMO. No write delays or waits of any significance - at least nothing that stops my photography.
Do not buy top-rated, name brand SD cards from online discounters because the chance that you'll end up receiving an order of counterfeit cards is too high. Unusually low pricing for a top-rated SanDisk or Lexar SD card usually means counterfeit. There is no secret sauce that only online discounters possess which can allow them, magically, to undersell Berger Bros or B&H or Henry's or Vistek or Adorama or Jessops (or any other recognized major retailer) on real, fast, top-rated SanDisk or Lexar SD cards. Believing otherwise is, I think, a mistake. It's the crazy/screwball retail season in Canada and the U.S. right now - U.S. Thanksgiving, Black Friday shopping, Christmas retail season, blah, blah, blah. Consumers be warned!
I can understand your concern. I have been into digital photography for 10 years and Nikon equipement for about 8 years. I have learned to use the little green light you mention to avoid losing my shots!
Since I started using my D7100 in August, I had to get used to that little green light going out before doing anything else with the camera like turning it off. I missed a couple of shots by turning it off too soon before the green light went out.
I am using SanDisk 16GB Extreme Pro SDHC, UHS-1 45 B/s cards for still shots. These are fast, reliable cards that are usually recommended for video. Even they need time to finish processing the 24MB files that our D7100s make in NEF format.
So there is probably nothing wrong with your D7100.
It wont double it because the JPEGs are substantially smaller than the RAW files, but it will slow things down some compared to shooting just RAW. It doesn't seem to matter whether you write the JPEGs to card 1 or to card 2 as far as speed is concerned.
Things will slow down even more if you shoot RAW with card 2 set to "Backup".
