Re: I want to know the FOV of Leitz variable eyepiece。20mm? 22mm? 25mm?
sorry,I meant FN(field number),not FOV(field of view)
i had understood that the FN of leitz veriable eyepiece is also variable? But i suspect its Fn<= 20mm at its 10x.So leitz variable eyepiece is not a supper wide FOV eyepiece.
