Per Msmoto, How about someone starting a discussion on a specific lens/body as desired and let the newcomers drop info here as related to their introduction to the Forum.
For everyday use I really like my 18-140 on either of the two cropped bodies I have. The D7200 and D5300. Some days the articulating back of the D5300 really helps by keeping me upright instead of lying on the ground. Such was today as I need to purchase something wider than my current widest Sigma 35mm A for the D810. For these two cropped sensor bodies I normally carry the 18-140mm on one and a 70-200mm f4 on the other. All I believe is missing is the Nikon 200-500mm for what I like to do.
