The 18-140mm is a DX lens. If your shooting on FX sensor the sensor is wider and you will pick up the inside of the lens. However, I would have expected the camera to go into DX mode.
Has anyone mentioned the Nikon 18-140mm is a DX lens, and that you're shooting with an FX body?
And that to keep that from happening in the future, you need to put your camera body in "DX Crop Mode"?

ok, another question. this morning i saw that the format was set to DX crop and not knowing any better changed it to FX (thinking well, it's an FX format camera). this resulted in the vignetting crap. however, i took a bunch of pictures yesterday with the format already and unknowingly set to DX crop and there was no vignetting so that solves that issue. however, with my 5100, i used a large image size which resulted in images with a size of 4928x3264. using the DX crop yesterday, i also set the size to large but those images came out with a size of 3968x2640. so why the discrepancy in size? the crop seems to create smaller images than a DX camera would.
hmm, done ridiculing now? like i'm not gonna buy the 750 because my current lenses are DX format? and i didn't buy them because they were DX, i bought them because i liked the focal length or the macro capability. they just happened to be DX. and stop with the legwork stuff too. i don't read every thread on here nor do i want to. right now i'm more interested in learning my new camera than i am in worrying about the lenses. just came across a situation that i'll bet is pretty normal for people who just made a huge upgrade in equipment.A good chunk of what you are experiencing is explained here http://nikonites.com/tutorials/20377-fx-vs-dx-uncomplicating-math.html#axzz3Noj172wV
You've got a great Full Frame camera, but your lenses are a bunch of DX glass (the 50mm is your only full framed lens). If you didn't realize the implications of this before you laid down the money for your D750 then your lack of legwork (and that's what it has to be because this is talked about all the time) led you to buy a camera that can't effectively use most of your lenses. Yes, there's a DX mode, but all that does is remove 55% of your pixels, turning your wonderful 24MP camera into a $2200 11MP DX camera. It does not take your DX lens and magically expand it to cover the FX sensor, it takes your FX sensor and tells the outside edges to take a break while the center does all the work.
Time for new glass. Until then, stick the 50mm on there and shoot.

thank you.. at least some people can be tactful on here.If you go from DX to FX, this problem is one that many face. I luckily bought most of my lenses with FX already in mind but some I had to upgrade later on. I tried to use some DX lenses for a while but DX mode on the D750 simply does not satisfy long and losing the lower end of the zoom lens wasn't a great option either.
To fully use the D750 you'll be forced to go FX with all lenses but since that costs money, it's not something we all can instantly replace. Until then, make the best of what you got.
