Hello Forum,

 

I am new to photography but willing to learn. I have several questions/discussions I would like to start.

 

For now, let me pose this question:

 

What is the difference between a telescope and a telephoto optical system? Both are used to get enlarged images of a scene.

 

I know a telescope is an afocal system when it is used to view distant object but is not afocal when viewing nearby objects.

 

Telephoto lenses provide an enlarged image and a narrow field of view.

 

Thanks,

Kavan
