I'm good with that. The grandson in question is only nine, but he's got a pretty good slapshot. Older grandson has one last football season at the HS level, but will probably play college ball somewhere. Younger granddaughter cheeleads and plays soccer, youngest grandson is an engineer, not an athlete, at least at this point. It is sad that the nearest ones are a thousand miles away, the furthest three times that distance. The time is so fleeting.

My wife and I are both pretty avid photographers, and when we started in the DSLR game, by accident, almost four years ago, we decided that we would either have to share a single FF outfit, or try to develop two DX/APS outfits based on our individual needs and preferences (She is retired, and gets to spend a LOT more time with the grands, so we are apart several months a year). We moved from D50 to D3200s, and now I've gone to the D7100. She's got the Sigma 18-300, which she loves, a Nikkon fisheye, a Nikon Macro, a Nikon 35mm 1.8 and 50mm 1.8. I generally carry the Sigma 10-20, Nikon 18-70, Nikon 70-300, and Nikon 50mm 1.8. We both have Neewer flashes, tripods, and other gear, and matching Billingham Large bags to tote it all around. I figure I owe her at least a D7100 upgrade before I buy anything more than a memory card for myself!

It's actually been a lot of fun assembling our kit, and doing it on a budget as well. Now if only I had more time to spend taking pictures with her.

Check out this Nikon link and look at the frame rate info: https://imaging.nikon.com/lineup/dslr/d7100/spec.htm
"Approximate frame advance rate
JPEG and 12-bit NEF (RAW) images recorded with DX (24x16) selected for image area: CL 1 to 6 fps, CH 6 fps
JPEG and 12-bit NEF (RAW) images recorded with 1.3x (18x12) selected for image area: CL 1 to 6 fps, CH 7 fps
14-bit NEF (RAW) images recorded with DX (24x16) selected for image area: CL 1 to 5 fps, CH 5 fps
14-bit NEF (RAW) images recorded with 1.3x (18x12) selected for image area: CL 1 to 6 fps, CH 6 fps"

LOL, use the 1.3 crop mode to get 1 to 6 FPS.

Same specs I have seen, but nowhere does it list the top write speed to the mem card. Here's my thought: a 14 bit lossless compressed raw file is 28.5MB, and the frame rate is 5 fps per the D7100 spec sheet. So, that's 28.5MB / image x 5 images / sec = 142.5MB / sec. My mem card's top end is 95MB / sec and the camera body computer probably can't write at 142.5MB / sec anyway, but that's what I don't know, the true write speed of the camera. What happens is the buffer fills up and the camera slows down until the buffer starts to empty into the mem card. I would really like to know what the top end write speed to the mem card is. If its lower than the 95MB/s of my current mem cards, I'm wasting money. If it's faster, than I would like to buy a faster memory card to get the full performance out of my camera.

Part of my point was indeed people are wasting money with super cards that exceed the camera capabilities.

Check out the San Disk site for their recommendations on cards.

Look at the last link from Nikon and in particular the size of the buffer portion I pointed out. Also,did you find any cards that the camera can write more than the average 70mbs I stated?

Maybe Nikon doesn't want to spell everything out, but it is quite apparent that under certain conditions, including file sizes and other stated criteria, that the supposed 6fps capability is for a second or so.
