I have the Sigma 18-35 f/1.8 Art . It is basically equal to 27- 50 mm field of view on a full frame Nikon. I use it as the main general lens on my d500. The lens is very well corrected as distortion goes for a 27 or 28 mm lens goes. It may actually be closer to 25.5-26 mm . Sigma lenses for some reason seem just a bit wider than their claimed focal lenght .
But the combination of this lens on the d500 seems like a match made in heaven. This lens with my Nikkor 70-200 can do 70 percent of my work . I also have the Sigma 8-16mm f/4.6-5.6 ultra wide . Which is a phenomenal lens if used with care . But the 18-35 f/1.8 is a great general purpose lens . Then Sigma makes the 50-100mm f/1.8 Art . That would be a great compliment to the 18-35 art . Best of luck

I did not read your full opening statement. My bad! But this Sigma is a great well corrected lens and great for landscape. You could probably get a used one for $600 or less.
An ultra wide is a tough lens to use and not always needed for landscape. I’m not a landscape photographer but have done some.
Each lens focal lenght has its purpose. For landscape a lens that is sharp across the frame and into the corners is usually recommended. One without a lot of distortion is also nice . The Sigma 18-35 art fits this bill just nicely. Read reviews on it . Many of the ultra wide lenses people here have recommended will stretch the corners and are softer in the corners. I’m not steering you away from an ultra wide lens because they have their use. But as one other person said to you they can make the subject look very far away.
In landscape photography a number of focal lenghts are needed. Most of this is dependent upon the scene. The lenses you have will cover all the sensors you want except the ultra wide stuff. But they will do it with a penalty. They are ultra Zooms. These lenses are not optically “premium “ . They have soft corners and distorted images throughout their ranges. Lenses that are very optically corrected are also very expensive. In most cases that is . This Sigma I suggest is not an ultra wide . It is a very well optically corrected lens and is very sharp. This is a good place to start in a landscape lens collection. 18mm apsc or the 27mm field of view is great for including a subject and telling a story. It’s not so wide you loose the subject. Except for far off things . Also this lens has a very close focus. This is great for shooting flowers or including something close up and large in the frame and having a story telling background.
So look up the lenses people have suggested and read many reviews. Decided on what focal lenght or lenghts you may want or need at the moment. Weight the odds before you invest. But you have a lot of these focal lenghts covered. Now if it were me I’d .......
Invest into good glass over super good camera bodies for landscape. Landscape photography doesn’t require the super fast auto focus the d500 has . A good body is nothing without good glass.

I got this lens new last year - pleasantly surprised at the IQ for such a cheap lens - yes plastic but well built and very light.

I recently purchased the Samyang 14 mm Auto Focusing iteration 2 months ago and love it. One of the senior photographers had referred me to it and I bought the newest model that was fully auto-focusing rather than the earlier model which was not. It was about $623.00 as I recall

The manual -focusing version was approximately $443.oo ,a considerable savings if your budget is tight.

Hope this was helpful.

I too have a D500 and a Tamron 1-24, and I'm very pleased with the results.

I have the Nikon 10-20 as referenced previously. If you like I can post or pm you several photos.

I'll second MT Shooters suggestion and add my own to it. I bought an 8mm Rokinon F3.5 (Manual Focus) from B&H for about $280 just for some fun. Found that I do like it, but would not put it up as a great lens. I might also suggest a multi-shot panorama to get wider. Best of luck.

Any feedback on Tamron's 15-30 f2.8?

The Tamron 10-24mm VC ultrawide zoom. Bought one for a trip to Yellowstone and found it to be killer sharp right out of the camera (D500/D7200). Didn't feel like spending twice as much for the Nikon because it's a lens that I don't use much except for landscapes. Tamron really nailed it with this lens!!

The Nikon 10mm-20mm AF-P lens is a very light, very inexpensive lens that gives very good results. It is a DX lens so it will work well with the D500. I bought this lens a while ago and can recommend it.

Allow me show my ignorance by asking what "screw driver focus" is. Thanks.

The older lenses use a screw drive where the lens barrel moves in and out while focusing. The newer lenses use internal focus where the elements move internally to focus.

Sigma 10-20mm. Love this lens.

And the newer lenses have a motor to drive it.
