Nikon also makes a very solid 28-300 lens. Ken Rockwell who has a very good site (https://www.kenrockwell.com/tech/00-new-today.htm) covers a wide variety of numerous Nikon lenses as well as camera bodies. Here is his link for the 18-300. Sites like www.mpb.com, www.keh.com or https://usedphotopro.com/ offer great savings on numerous Nikon lenses & grade the lenses from 1-10 with 10 being highest or LN (like new) to "seen better days" and offer return policies on anything they sell

I had a D90 for many years and primarily used for traveling. I ended up using just one lens most of the time. As stated above, Nikon makes a 18-300 DX lens and it isn't perfect, but it met my budget needs and tooks 100s of wonderful photos; no regrets, only memories...

I have a Tamron 18-400 I posted a while back that didn’t sell. I’ll be posting it again soon along with a Tamron 90mm macro.

Be careful about getting a lens that is too large for the camera body (test: would you be able to take a one handed photograph?). I have a D5500 and do not like using it with the 70-300mm lens.
I do not try to shoot one handed photographs with a long lens, but I DO pick the camera-lens combo up via a hold on just the camera when I am preparing to shoot.

On my D90 I use the 70-300mm lens 😎

If you want a prime lens, buy a prime lens. Zooms are great today, but you really have to be at the highest end of highest-end zooms to get a zoom that rivals a prime.

A 28-300 has worked well for me dating back to the introduction of the D90.

When I was using a D90, I found the 18-105 kit lens to be an excellent lens. I've made 20x30 posters from pictures taken with that lens with excellent results. I wish I had it back. Ken Nagel

I have the 18-105 on my D90. I also have several other Nikon lenses that will auto focus on the D90 but the 18-105 and the 24-120 f4 are the two that are most used on the D90. The 18-105 is noticeably lighter than the 24-120. I still like the D90 for travel, camping, canoeing etc. It's lighter and smaller than my D500. It's also worth a lot less should some kind of mid-hap were to occur.

I use the old Nikkor 18-135 3.5-5.6 on one of my D90s and the old Nikkor 24-120 3.5-5.6 on the other. Both produce excellent images. Both are non-vr.

The OP's tittle is a bit misleading. When he said he wanted a zoom as a prime he meant a general purpose all around zoom lens. He didn't mean a fixed focal lenght lens.

Im not much on WA so anything from say 24-40 on the short end and at least 200 on the long end, 300 better. I think that 35-300 would do me fine as an everyday lens, for example if that gave me normal lens quality. You know, the quality or near quality of a good 50 or 55mm lens. I use a Canon 70-200 a lot. Some length, good quality and reasnably close to 55 on the short end. Harry

This is confusing...

..."zoom lens to use as prime"...

You may not be aware:

- a zoom lens is one that has a range of focal lengths... such as 18-55mm, 17-70mm, 70-200mm, 70-300mm, etc.

- a prime lens has only a single focal length... such as 24mm, 50mm, 85mm, 200mm or 300mm.

Do you have any lens at all with the 90D? If so, what lens is on it?

You mention "300"... which suggests a telephoto lens. Some people also conflate "zoom" and "telephoto". Telephoto is a lens that can make distant subjects appear closer. A zoom is a lens with variable focal lengths, which may or may not be "telephoto". Some zoom lenses focal length range includes wide, normal (or standard) and telephoto focal lengths, all in one. Others zooms have ranges that are just ultra wide to wide, or wide to normal, or normal to telephoto, or telephoto to telephoto.

On a D90 any focal length longer than 30 or 35mm is "telephoto" (whether it's a zoom lens or not).

With all Nikon cameras there are some possible lens compatibility issues. The D90 only has a few limitations. According the Ken Rockwell: "The D90 works perfectly with all traditional AF, AF-I, AF-D and AF-S lenses. AF-P Stepper (Pulse) autofocus motor lenses are useless on this camera because they can't even be focused manually."

Here is more description of the D90 at Rockwell's site: https://www.kenrockwell.com/nikon/d90.htm

Nikon has the 28-300 but I would avoid such a high ratio zoom.
