I have a nikon 16-85 lens.is it worth getting the nikkor 12-24 or 10-24 lens? I?

I love shooting landscape… If i should get another lens… Which one would it be? Nikkor 12-24 or nikkor 10-24?

Going down to 12mm wouldnt really be worth it there's not much of a difference, the 10 might be though (haven't had either lens)

If you are oging to be shooting much wide angles, you might need a 10-24. But I have a single 18 to 200 mm lens, and i'm pretty happy with it. Serves my requirements very well and am very happy with it, don't need anything more. But yeah, this varies with person to person and what they fancy

Only you can answer that question.

Here is a link to what those lenses "see"

The 12-24 lens is a constant aperture lens at f/4

Use the Nikon lens simulator to see how much difference 10 vs 16 mm is going to be.

There's one issue though with using the simulator. If you are using a DX camera, just pick DX for both lenses, regardless of whether or not they are DX or FX. Both lenses will look the same on a DX camera whether or not they are DX or FX, and it just leads to confusion when using the simulator.

I have a Tokina 11-16mm lens along with a Nikon 18-200mm. The difference between 11mm and 18mm is pretty significant for landscapes, scenery, or inside buildings. So if you are in that situation, it might be an advantage.

However, realize that the perspective distortion at 10mm is going to be pretty severe, which is another thing the Nikon lens simulator will not show you. You will either have to learn to compose your photos at 10mm to minimize distortion, or use post-processing to fix it.

The above photo is an example of perspective distortion at 11mm (using my Tokina 11-16mm). Notice that on the right side, the people all tend to lean towards the left, while on the left side, they seem to be leaning a bit to the right. Also, the bow of the ship on the right is distorted; it does not have that severe of an angle.

You would not notice this as much with the typical scenery; mountain range, etc. But buildings and people will be noticeable.

This type of distortion is primarily the function of the short focal length, so it would be expected for any 10mm lens. Essentially, the lens is is so wide it is beginning to take on the characteristics of a fisheye lens.

I use a Sigma 10-20mm - fantastic lens that gets me some great landscape shots.
I don't know anything about the relative quality of those lenses so based on focal length alone I would go for the 10-24. There's a noticeable difference between 10 mm and 12mm.
