Depth texture seems odd and inaccurate

I'm working with SharpDX. I've worked pretty extensively with OpenGL, and so far my project with DX11 has worked exactly as expected. However, now I'm working on making a depth buffer that I can also bind to a shader. I've got the shader resource view bound, and it appears to be passed in correctly. However, the range that the values are in seems completely wrong. When I use Graphics Debugger and view the image, the entire depth view is between 0.987 and 0.997. This range does change as the camera moves, and yes I do understand that depth is not linear in view space. The issue is that with my near and far frustums being set at 0.1 -> 200.0, the whole scene (even at 10ish meters) is around .99 in depth. The only way I can get any lower values is to have the camera directly intersect a triangle, at which point it still seems to fade to solid white very rapidly. Even if I don't bind the shader resource view, the issue is still there. Here's the code that creates the depth texture:

var depthTexture = new D3D11.Texture2D(renderer.GetDevice(),
    new D3D11.Texture2DDescription()
    {
        Format = SharpDX.DXGI.Format.R32_Typeless,
        ArraySize = 1,
        MipLevels = 1,
        Width = Camera.GetWidth(),
        Height = Camera.GetHeight(),
        SampleDescription = new SharpDX.DXGI.SampleDescription(1, 0),
        Usage = D3D11.ResourceUsage.Default,
        BindFlags = D3D11.BindFlags.DepthStencil | D3D11.BindFlags.ShaderResource,
        CpuAccessFlags = D3D11.CpuAccessFlags.None,
        OptionFlags = D3D11.ResourceOptionFlags.None
    });

Here's the code that creates the depth stencil view:

D3D11.DepthStencilViewDescription depthDesc = new D3D11.DepthStencilViewDescription()
{
    Format = SharpDX.DXGI.Format.D32_Float,
    Dimension = D3D11.DepthStencilViewDimension.Texture2D,
    Flags = D3D11.DepthStencilViewFlags.None,
};

Here's the code that creates the Shader Resource View:

gBufferShaderViews[2] = new D3D11.ShaderResourceView(renderer.GetDevice(), depthTexture, new D3D11.ShaderResourceViewDescription() {
    Format = SharpDX.DXGI.Format.R32_Float,
    Dimension = SharpDX.Direct3D.ShaderResourceViewDimension.Texture2D,
    Texture2D = new D3D11.ShaderResourceViewDescription.Texture2DResource()
    {
        MipLevels = 1,
        MostDetailedMip = 0
    }
});

And in case it's relevant, here's some code that seems related:

viewport = new Viewport(0, 0, Width, Height);
viewport.MaxDepth = 1.0F;
viewport.MinDepth = 0.0F;
d3dDeviceContext.Rasterizer.SetViewport(viewport);

I've tried using R24X8_Typeless / R24_UNorm_X8_Typeless as the format as well, it had the same exact issue, in the exact same range. Is there something I'm missing here? Could it have to do with the projection matrix? I'm using the built-in Matrix.PerspectiveFovLH function that comes with SharpDX, here's the call that builds that:

projection = Matrix.PerspectiveFovLH(fov * 0.0174533F, aspect, zNear, zFar); //The constant is degrees to radians

Ignoring the depth buffer, everything renders fine (including no issues with z-fighting or other depth issues).

Thanks in advance for any help that can be given, if more code is needed just let me know and I'll get it.
