This could as well be posted on another forum such as Leica but probably fits best here on Zeiss because of one of the questions below to do with poor light, a Zeiss speciality what with AK prisms in many last generation and some current generation models.
It was pointed out to me in various messages that it is best to set dioptre over a range such as 50-100 yards. Befere being told that I was setting it at much closer range, for instance as close as 10 yards. My thinking was that close focus is more intolerant of slight error so setting it on a close target would ensure better pinpoint accuracy. Out of interest why is this flawed?
The other thing I wondered about dioptre was whether the difference between my (our?) two eyes varied depending on light levels. Since different receptors - if that is the right technical term - are at play in daylight compared with in darkness, do low light and night time viewing affect the dioptre setting?
Thank you,
Tom
