Oddly enough, dxomark gives the 18-140 a rating of 16 (roughly 32%)
while the 18-300 gets a rating of 19 (roughly 38%).
I have the 18 to 140 and have learned not to use f-stops past f11
because the sharpness plummets.

Or not if you want real, not alternate facts. . .

Past f11, particularly on a DX camera, sharpness decreases noticeably because of diffraction, which affects every lens. (look this up if your are not familiar with the term) In situations where depth of focus is critical, going beyond f11 can be a reasonable tradeoff. Unless your lens is defective (unlikely) there is noting special about the 18-140 in this regard.
It is because diffraction affects this lens so badly that I've decided not to use it past f11.
Yes, I could get more depth of field at f16 or f22, but the loss of sharpness is dramatic.
I am aware that diffraction affects all lenses.
Different strokes for different folks. Rather than ask how others like it, rent one, put it thru it's paces & decide for yourself. One person's trash is anothers treasure. In other words, what another may love, you may not...
My Leica V Lux only has 25-400 (2.8-4) light as a feather and great image quality. Just can't leave the newer 24-70 off my D750 or 70-200 (both 2.8) off the D810. The latter 2 are like building muscles sessions but the image quality of both are worth the pain. Remember the pleasure is forever. Larry
Hi,
Been reading posts for a while and learning quite a bit. One question that has bugging me. Read a lot of posts about "Kit Lenses". My questions are: How does a lens become classified as a kit lens? Are all "Kit Lenses" zoom lenses? Is any lens bundled together with a camera body for sale automatically a Kit Lens? From what I read I get the idea that, in general, "Kit Lenses" are inferior or low quality lenses thrown in with a camera body to make it look like a good deal. Is that an accurate explanation?
Thanks for any info to clear this up for me.
My D7100 only knows my 18-200 VR2 lens. Admittedly, I'm not a pixel-picker, but I like the lens. I have not tried the 18-300 lenses.

I use the 18-300 as my every day lens, no complaints.
BTW: Per the Nikon web site, the TC does not fit this lens.
But Kenko Tele Pro's will.

A lens like the 24-120 f4 has often bundled with either a D750or a D810. It isn't a low quality lens. Same with the 24-85VRII. Most kit lenses are zooms rather than single focal length. The exception would be a 50mmf1.8 as a bundled lens.
I purchased the 18-300mm f/3.5-6.3 about a month ago. I haven't decided as to how well I'm going to like it over all yet but I will say I'm not real impressed so far with image quality at 300mm, shooting birds at approximately thirty to forty feet. I've been trying everything, hand held, monopod, VR, no VR, fast shutter, higher ISO. Gonna try a tripod when the latest storm is over. From what I've read on here I think I'm expecting too much out of it. Not going to name any names but after seeing the photos posted by many of the people on this forum I'm never going to be satisfied with less than tack sharp images again. Thanks a lot people!! 😀 If anyone has any suggestions, I'm all ears.
Oh, by the way- using a 300 mm lens with a tripod should be the FIRST thing you do!
If you're shooting birds, you may want to consider getting a gimbal head for your tripod.
Unfortunately, this lens is incapable of shooting a sharp image at 300 mm no matter what you do.
