kid in 2040: "whats a RAW file, daddy?" :)

There is your problem: Learn how to cook!
(Re:What to do, camera-wise: Larger sensors are more fun!) My favourite toy is a 5x7" :) - camera that is....I'm in love.....

"because things like this keep the camera people in business."
- Uphill battle that. 43% decrease in DSLR AND compact camera sales across the board last year, thanks largely to e.g. smart-phones (which reflects the trend to ease-of-use and technical non-commitment of the average owner - i.e. most cameras have become overkill).
[Personally, I haven't bought gear (let alone new gear) since 2009, nor do I see an urgent need to re-evaluate that.]

- Photographed sea-ice from underneath by putting my tripod and camera upside down under it. 4s exposures...
- Built a 5x7" underwater camera and started to lug that about to get a different shot (not that daredevily I guess, just a technical effort).
- "Trespassed" a fair few times as well, I think....

I kept a rough tab on my purchases and sales until recently via a spreadsheet, when I got bored with the exercise and saw the generally positive trend. I have owned way over 100 lenses and close to 100 cameras, but have been out-of-pocket less than $4000 over the last 20 years. Reason: Nearly nothing I bought was ever new gear and I usually traded well. Not getting paranoid about "upgrading" helps; I just buy stuff in kits and sell what doesn't work for me, or is in excess of needs.
Now I have three 35mm cameras, one DSLR with a few lenses, three cheap medium format cameras and one large format camera, also with a few cheapish lenses. Am going to cut down further to one 35mm camera and one medium format camera (keeping the DSLR and LF). Less seems more.

I had a lens for Nikon until recently: A 65mm f0.75 Astro Tachon ... Mount diameter obviously wasn't the problem. :)
(filter size 95mm). It only fitted my F2 with the prism off though.

Got a mint Vivitar 200mm f3.5, M42: 40$ plus 30$ shipping from the UK. Built-in hood; filter size 62mm, runs smooth and like new.

'Love that reply, Winterrose :) Hey, I used to live around Hope Island; loved the place!
I'm personally not brand loyal; nothing wrong with Canons etc. either of course.
Back to the question: Personally, I'd be over the DX/FX swapping game; but then I play with too many other formats anyway (DX to 5x7"). Running about with only one system seems easier to me.

Not sure what you want this for; not counting excess pixels one hopes. Sensational photos have been taken for the last 100 years.

Schneideritis is not delamination, as earlier suggested (I just read that, sorry :)), either. Delamination would indeed have been more serious.

Well, to be fair, the 28-300 is a really nice walk-around lens, but is not particularly good at isolating the subject from the background.
Personally, for an FX Nikon and good flexibility, getting a 17-35 (or 16-35), a 50 (1.8/1.4/1.2...whatever) and the 70-200/2.8 is a great set to have and so many pros use that as their standard kit. If you do a lot of portrait work; augment that with a fast 85, and/or, say, a 135/2 DC. However, these lenses only shine, if you know what you're doing. Most people have far nicer gear than their skills will do justice these days, but then pros appreciate that, too: At least that keeps the prices down.

Good point.... RAW vs jpeg "discussions" aside, I am somewhat comforted by the fact that I occasionally still shoot (e.g. 5x7" ) on film. Many of those images, taken over the last 13 years, are favourites of mine; those images can still be printed in the next century, by whatever method and medium then available. But I am not intending to open the dumb digital vs. analogue discussion. Just sayin'; I use both and find saving digital files in more than one format the obvious and easy answer.

...unless you want to isolate your subject.

Well, I better suggest to Dave Burnett that he stop using his Holga then, LOL.

Pre-AI lenses won't mount. ALL other non-mirror lock-up F-mount Nikkors will be fine on the D7000 (bar those dumb Pronea IX-lenses). One of the nicest DX cameras out there.
