NocPix Nite D70R

[Keith Edmunds]

Its not extra bulk... looking across the internet people get confused by all this a lot. Basically if they used a 70mm lens and F1.2 the lenses would be huge in weight and size. To reduce this, they use higher F stop lens , which maintains the 70mm focal length but reduces overall size and weight, this reduces sensitivity somewhat. Daytime zero difference at nightime and slight difference at night can be negated by using good IR illumination .

Could you tell me the actual, physical diameter of the objective bell please as I think I have been thrown by the '70mm' in the description. Also, the mag ring on the ocular lens looks pretty beefy - measurements on that would be really handy too. Many thanks.
