It doesn't seem like there has been much discussion about the D5200 so I thought I might add one (even if no one cares and there is already a D5300
. Personally it seems like the best deal out right now. D7100 performance and I got my refurbished body with 18-55 lens (it was cheaper to get this kit then the body only...I don't really have a use for the 18-55, but it might be a nice beater lens for trips and stuff. If I lost my D5000 and 18-55 I would only be out a couple hundred vs $1500+ for my other lenses) for $440.
Out of the box the D5200 has more buttons. It feels a little different in hand, but it is subtle. The LCD on the back is much larger and better. It has a newer look to it.
Easily distinguishable features. Native ISO 100. The auto focus is much better...it seems quicker and locks fast. I just took some shots around my living room at ISO 1250 and they look plenty usable, while I wouldn't ever use an ISO that high on my D5000. Some extra buttons...shutter type button, live view slide next to shutter release, a dedicated record video button. It seems more advanced then the D5000. The screen is newer looking and laid out different. It has a new interface I guess you could say.
I think one thing I liked more on my D5000 is the flip down screen instead of the sideways flip out on the new D5200. Minor change and I usually leave mine flipped around with the screen exposed anyway, but just noted.
Live view is much quicker to turn on and use. The old live view wasn't very usable. I only used it a couple of times on the D5000 because it was so cumbersome.
24.1 MP vs 12.3. Room to crop. File size is much larger. RAW on the D5200 is 36MB. So you need fairly large memory cards. With a 32 GB card you only get 800 something pictures in RAW only.
So far all I have noticed. I will update this thread as I use my camera more. Just didn't see any love for the camera and it performs on par with the D7100. I think there are lots of people that wonder if they should get the D3XXX cameras vs the D5XXX ones. I think the D5XXX line still has plenty of features to justify the little extra cost. If nothing else the auto focus is worth it. I kept telling myself that I would get the D7XXX line because of the more pro features and here I am again. I think the couple of added buttons do help on the D5200 vs my D5000. I don't really need commander mode for the flashes and I have all AF-S lenses so old lens compatibility isn't a problem. Set my fn button to ISO which is probably my most used thing to change.
