Alternative books:
Mastering the D500, Rockynook.com
Complete guide to D500, Thom Hogan
David Busch's Guide to D500

The first two are available electronically, not sure about the third.

Hogan's is only electronic.

There are others in an quick Amazon search.

The first two, the authors really use the cameras before the book is published.

In times past, food was not so easy to obtain, and getting it used much more energy in comparison.
Now, jobs are not as movement oriented for many people and higher calorie snack are available.
And that's why I am twice the weight I should be.

I've been losing the same 20 pounds for years, staying within a range that is twice what it should be.

Too bad it didn't have its namesake,
Both are well designed for there purpose.
Beautiful image.

Beautiful car. It may offend a purist, though.
In 1965, Shelby GT350s were only sold as white, with Guardsman Blue top stripes optional.
It was 1966, when other colors were offered.
Hertz cars, about 1,000, got bronze stripes. Non-Hertz cars got white or blue.

I acquired my D500 from KEH, during their Black Friday deal a couple of years ago.

One possibility for you if no one offers.

Mine is not available, sorry.

That's a really nice charging stand!

Regarding the op, USB-C with Power Delivery devices will slowly reduce the need for proprietary chargers.
It will take time to get there, though.

Package theft is a major problem in neighborhoods near me.

The thieves literally follow the delivery trucks and pick up packages after the UPS/FedEx/USPS/Amazon person walks away.

With Covid-19, many delivery companies are no longer enforcing the signature requirements for delivery.

FedEx will hold packages at local Walgreens. That is not always allowed, though.

Amazon also has delivery arrangements with various places, that may be local to you.

UPS will at least hold packages at their facilities.

Definitely options to make use of.

Uniquephoto.com is in Fairfield, NJ.
If you want to stay local.

At the time, there was a backlash, since the older mounts were incompatible with the newer EOS mount.

Had to buy all new lenses if you got a new camera, etc.

Thank you, I always thought "automatic" was not an appropriate word. Yes, that is how Nikon documented the term "AI"

AI - Aperture Indexed. These lenses usually have an aperture ring. They can Manual focus, or AF, or AF-D.

AF - screw drive autofocus
AF-D screw drive autofocus, with distance encoding
AF-S Lens motor autofocus, includes distance encoding
AF-P Lens motor autofocus, but a different type of motor (pulse)

E-type refers to the aperture control, it's electronic, not mechanical and only newer bodies support it.

G lenses do not have an aperture ring

There was a lot of effort to maintain some degree of compatibility from the original F-mount of 1959.
Canon decided to do a clean break from prior mounts when they created the EOS specification.

Which approach is better? Probably like beauty, it's in the eye of the beholder.

That's why I still have a D5300. But I believe the D6 has GPS built in.

Some of the bridge cameras and the water resistant point and shoots also had it.

Sadly Snapbridge linking to phone GPS is now the preferred solution for Nikon.

I didn't get such a cool case with my D500 from KEH.

Luckily I had gotten something before that works. 😅

A 90 day warranty limits their liability so they can offer items at a lower price.

Accounting and Statistics, not only market forces set the price.

In their mind, to offer a full year warranty, they would have to charge more.
