Not feeling the groove with the trusty ol’ Objective Lens Cap or those Bikini Covers? Don’t see the fuss about extra armor for your device?
Well guess what? There is an third option!
So, if you’re ready to jazz up your lens protection game and add a touch of style to your device, this option could be your ticket to optic awesomeness!
Should I Make A Hole In My Cap?
Let’s begin by addressing the reason why – If the ambient lighting is excessively bright, causing your device’s autogain to automatically lower the brightness, simply flip on the cover. Modifying the cover with a strategically placed hole, will effectively expand the focus range without compromising performance.
FYI: Turned off tubes can get damaged during day-time when the lens is not fully covered.
If you wish to make a hole, here are some recommendations:
A .223-.250″ hole is ideal for general-purpose work, It will re-focus down to 2-3 ft. (just use a 5.56 round to punch a hole through the cap)
If you want better than that, for reading maps and so forth, you need to go down further, to .125″ (0.3 cm) or below.
For day use, I’d use nothing larger than a pinhole, like .015″ max. (0.04cm
