It seems to me that a better question would be to ask the type of photography the photographer does. I am a sports photographer and use the Nikon 70-200 F2.8 and Nikon 300mm F-2 outdoors (football, soccer) and a Nikon 24 -70mm 2.8 in doors (basketball, VB)

My LR catalog shows 2720 images in 2020. The metadata panel shows 1902 images for which lens data are available. Of those, most of them are from the 24-70, which is what I would have guessed. Second is the 70-200, which would also have been my guess for second.

The difference between 2720 and 1902 probably represents a lot of shots my wife's daughter and her partner sent of their trips. They were primarily taken with an iPhone and some of them came through social media with EXIF data stripped off. A number of the images are scanned.

Another tool that may be of interest to some is ExposurePlot. It can take a folder, analyze all the EXIF data in files found in that folder (and subfolders, if checked) and plot a histogram of focal length, ISO, aperture, and shutter speed. If you have money in your pocket and think you need a new lens, this will show you which focal lengths you use most and may help in the decision.

The ISO plot is interesting. My DSLRs are rarely set below 400, but there are many images represented below that, down to ISO 20 (which none of my DSLRs has available). Probably from the iPhones. Also none of my lenses goes below f/2.8, yet there are apertures down to f/1.8. f/8 is pretty well represented, so I've been there.

With my Sony 6500 apsc, I use the Sony 70-350mmG and the 16-55mmG most frequently, primarily for landscapes, moonscapes, and occasional wildlife photos. I like travel photography also, but haven't gone anywhere out of the country since November of 2019, pre-Covid. Hoping to travel again within a year.

Not true. Lightroom lets you process your photos much like a traditional photo process. It is pretty easy and very intutive.

I would be cautious about "trading up". I have an 18-105 DX, and it has been my most used lens by far since I got it in 2009. In 2019 I bought a used 18-200mm DX and got rid of it within a couple of months. It just was too soft, overly heavy, and not truly 200mm at close range. I cannot speak for the 18-300, but I would suggest not getting rid of the 18-105 until you have done a side-by-side comparison and are sure it really is an upgrade.

I did buy a used 18-140 DX from mpb.com, in part because it was a great price, and to have as a backup. I can see no difference in the quality of the images when doing side-by-side comparisons. That said, I have no intention of letting go of my 18-105 which has served me well for over ten years.

My Nikon 200-500 is permanently affixed to my Nikon D810 for winter birding opportunities. The D750 has the Sigma 14-24 art ready for aurora possibilities. Other lenses are handily available should the need arise. Thankfully just opening the window and shooting from inside works for our minus temperatures.
