I did consider that because it is priced at a point where I could afford to get it really soon, definitely much sooner than I would be able to get the 6D or the D800. However, I REALLY want a full-frame camera. I like that the D7100 is 24 megapixels, though. The fact that the D800 is so high (a staggering 36 megapixels) is a bit bothersome because it means I'll need way more storage, with respect to both the SD cards I will use and HDD space on my computer. I do have a 3TB External HDD, so maybe the latter won't be too bad.
It has a FX mode. tho of course not actually true FX. also, the IQ is fantastic, that's the difference. you can always use a wider lens. for instance - a 35mm DX is about 50mm FX.
All those pixels don't mean much unless you're doing HUGE prints.
When you shoot RAW you just capture data so you can sharpen, pull details out of shadows, etc.
all storage is temporary so it doesn't matter how much space you have; you can delete from your computer after you burn to at least 3 discs. you also should copy disc regularly.
jpeg is a lossy format so doing that will degrade the files over time but most people can't tell
Another concern of mine is the buffering on the D800. I've seen videos where after a quick burst of continuous shooting it can take the D800 up to 2 1/2 minutes to buffer, rendering the camera useless for that time. So if the perfect shot comes along while in this state, then I will miss it. That sucks for events where things are happening rather quickly (like parties or clubs), which are places where I like to get a lot of candid shots, so people are moving around a lot, rather than posing.
nah. if you're shooting 14 RAW there is a buffer slow down but nowhere near 21/2 minutes. where'd that come from? shoot RAW 12 and you'll be fine.
use a fast lens and you'll get all the candid shots you want.
