I've been using my only 50mm lens with my D90 when I got it when it was first released. lol I do however rent lenses for gigs. I started doing that because I couldn't decide on which to purchase. Before shooting with my D90 I owned a sweet SLR for years which is why I want to go FX. If I got a D7100 it would feel like a newer camera but I really wouldn't have anything that would excite me. The 51 AF points I saw the advantages of using that on a D300. So for years I forced myself to use just the D90 and 50mm until I was ready to move to my next body. I don't like to do any stitching. I want to capture what I see.
I know the price of the D750 will drop (eventually). If someone is buying their first Nikon, they have lots to chose from. My reasoning for going to the D750 is the same as when I bought my D90. Size and pro-like features. I can easily shoot with the D810 but I like carrying a slightly smaller body.
The D90 with a 50mm 1.8 is a great combo. I use it a lot. I've also come to love the 35mm DX lens with the D90. At first I felt it overexposed a lot compared to the 50mm but once I got used to it and realized how to adjust I love it. I too have come to feel that I'm ready for more than the D7100 brings. It's a nice camera and I like the feel and build of it but I want more low light performance. Stitching does have it's advantages. It lets you get some wider shots from a closer position which can create some interesting perspectives. The widest lens I have at the moment is the 18-300 and it's not at it's best below 35 (maybe even 50). Maybe one day I'll get a true wide angle but nothing below 14mm or 16mm probably.

Before you guys go for the D750 you might want to consider the ligh leak/reflection issue that is now surfacing:

Looks like it's a free D760 a year from now.![]()
Ugh. OK, I guess I'll watch this one for a while. Good thing I have time. I'm sure it will go the route of most of these new device, new problem issues. Maybe some denial at first. Some extremely emotional internet arguments from both sides of the mine's broke / mine's fine camps and then hopefully a resolution.
