Render camera is different from the viewport camera I've been trying to make my render camera match the viewport global camera, but I can't find the proper settings. It seems that the viewport camera is different from the standard render camera though they have the same Focal Length (50mm). Moreover, there's no viewport camera's size option.
Viewport camera:

Render camera:

Viewport camera shows more extreme angle and does not distort the image.
Render camera looks more like orthographic.
How can I configure my render camera to match the viewport camera (to get the same render result)?
Thank you for reading my post!
Your camera settings might be off, make sure to in the sidebar under view that you are using the same camera in the view properties and the scene properties. Images to help you find where they are. 

Make sure that the local camera (One you want to use for preview in viewport) has the same name as the one in the scene properties.
