Tried today to take a picture through a binocular with my mobile phone.
There seems to be some mismatch in optics. The edges blur out probably because the binocular lenses are optimized to project onto a curved retina, while the cellular phone has a flat sensor?
Also, there is some heavy “blue” fringing. Is that out of focus artifacts or the mobile photo sensor?
The binocular is a 16x50, so I wonder if there is a sweatspot with a light diameter of (50/16 =) 3,125mm, slightly just outside the lens?
If I try with a piece of paper, I get a sharp circle of light probably 5mm outside of supporting rubber-rings. I probably get better images if I manage to place the mobile camera sensor at that position…?
I really did try to find an optimal distance. But I have to conclude, the human eye is an amazing thing,
I wish I had five arms or hands, I cannot compete with the human eye and the adoption to a regular binocular optics without the arms of an octopuses…
If I pick up a binocular I can surely see sharp images with the human eye, while doing the same with a mobile device… and taking photos… I can see blurred images. I’m sorry it is impossible to take sharp images…
The threshold seems to far exceed my human capability to position a mobile camera a few millimeters away from a binocular lense. Maybe Im just weak?
