Nikkor AF-S DX 35mm

Does the Nikkor AF-S DX 35mm remain the same angle of view on a crop sensor camera that is 35mm view? Does it apply to other DX lens also?

A 35mm lens is always a 35mm lens: the field of view depends on the sensor it is used on.

DX just designates that it is designed to work on a crop sensor camera. That just means it will only project an image circle large enough to cover the crop-size sensor.

If you take a 35mm f/2 (an FX lens) and a 35mm f/1.8 DX and place both on the same crop-sensor body, you'll get the exact same thing. However, placing a 35mm f/1.8 DX lens on a DX body and a 35mm f/2 lens on an FX body will give a vastly different image. To get the same image, you have to have either of these:

35mm on DX -> ~50mm on FX
24mm on DX -> ~35mm on FX.

The trick is that you cant really use a DX lens on an FX body (you either get very dark corners (totally black or the body automatically crops to the DX size).

If i understand if I used a Nikkor AF-S DX 35mm 1.8 on a DX body crop sensor, I would get the same view of field of 35mm lens.

No: you'll get the equivalent of a 50mm lens on a full-frame body.

WHenever youre using a DX body, regardless of lens, you have to multiple the focal length by x1.5.

Crop factor for Nikon DX Camera = 1.5.
Just time the crop factor with the focal length = 1.5 X 35mm = 52.5mm focal length on Dx camera.

Crop factor for some Canon Dx Camera = 1.6
==> Equivalent focal length = 1.6 X 35mm = 56mm

Crop factor for some Nikon J1 Camera = 2.7
==> Equivalent focal length = 2.7 X 3.5mm = 94.5mm.

To get 35mm , I use some cheap converter..

I still stugging to buy either nissin i622 markII vs YN465..
