Me, I absolutely love Nikon glass, and like being able to use an old lens from the ’60s or ’70s in my D7000 (like my F/1.2 50mm primary).
The cheep come-with 18-55mm lens is phenomenal, and the 55-200mm featherweight plastic body lens is even better. I snapped a pic of a blue heron framed on the other side of a pond by a ‘V’-trunked tree on an “island” in the middle of the pond. Not only could I see the heron’s eye in the shot (at 100% crop), but I could clearly see his pupil as well.
And that was when I only had a D3000 and the cheapie 55-200mm lens!
That said, I get probably 95% of my shots with my 28-300mm zoomie, and failing that, with my 70-200mm f/2.8 when I need speed, or the aforementioned 18-55mm when I want wider landscapes or macros. Aside from maybe carrying the 18-55 separately, it’s just my camera with the 28-300 in a bag.
And I’m talking about crystal-clear shots of bugs in flight where you can count their nose-hairs.
Funny thing is, on one site where I posted a pic of a dragonfly in flight, some a-hole was “calling me out” for faking the pic, yelling “It’s photoshopped!”, etc.
Ummm, when odos are in-flight, their tuck in their legs like helicopter skids, which is exactly what the pic showed. And just for spite, I posted like 8 more in a series of pix of the little beastie.
So, yeah, for me, I looooove Nikon glass, and the compatibility with even ancient lenses.
And I agree with Ken Rockwell that cameras start to suffer “digital rot” right from when they come off the assembly line, but lenses last forever (except for maintenance once every decade or whatnot). Cameras will get bigger faster sensors, bigger faster processors, etc., that start going antiquated from day 1. But lenses are forever.
