Can someone advise me on the difference between 60mm and 80mm scopes.
I appreciate the size and weight difference and that a lower magnification lense wold be required for a 60mm but what difference is there in the optics under normal viewing conditions?
I notice when out birdwatching that 60m seems to be the preferred
I am initially considering the Opticron HR66 GA ED and the Kowa TSN821M as they are in my price range.
Any help on the lense sizes would be greatfully received.
