Question About Camera Shakes and Render Textures

I’m in the process of making a sniper scope. I’m using a widget for the scope and blurring the rest of the background. Because the blur affects the entire screen the scope appears blurry. To fix this I’m using a render texture applied to the inside of the scope widget. I also have a camera shake applied to the player. I have two problems and I can figure either of them out. First, when I zoom in I am lowering the FOV of the render texture to bring the target closer but the zoom is going the wrong direction. Second, the camera shake is only affecting the blurred part and not the render texture. Can someone help me understand what is going on?

I was looking at the render texture in the widget and noticed that the image looks squished. This looks like it has the same proportions at when I aim. This might have something to do with the problem but I’m not sure why it looks like this or how to fix it.
