hello.. ^_^
why when I try to focus my binocular clockwise, the "super-sharp" focus image is easier to obtain than when I turn it anti-clockwise?
so, when I focus from far to close (anti-clockwise rotation in focus knob)..I over turn it then back a little clockwise rotation to get the most sharp image..
is it the eyes? because nothing wrong with the image or diopter setting...just realized it..
do you ever had the same experience? ^_^
for your kind help, many thanks before...
best regards
Galih
I think it´s easier to be precise while pushing with your index finger, than when pulling with it. I devised an insane test after reading your post. Draw a series of lines on a page, each line 1mm apart. Place the page on a table. Put a small coin on top, at one end of your series of lines. Pick a line, and push the coin to it with one smooth movement. Now try from the other end, this time pulling the coin with your index finger (the direction will depend on whether you´re left or right handed). I think you´ll find my amazing discovery is true. Do I get a Nobel Prize?
Sancho,
It could at least be an exhibition sport in the 2012 games. Start developing a look and an attitude to go with your skills.
Galih,
One expert, a Mr. J. W. Seyfried, author of "Choosing, Using, and Repairing Binoculars", insists that from near to far is indeed "the correct" way to focus.
The rationale, I believe, is that in going that way, as you approach focus, you eye's natural instinct will engage a focused view, although not a comfortable one, when the virtual image is too close, and follow it as the focus continues adjustment to a comfortable sharp setting at or near its own distance of muscular relaxation. With some experience, the user will stop at the correct place.
If focus is approached the other way however, the eye cannot possibly focus on the image beyond its own personal "infinity", or relaxed state. So the eye sits there kind of confused, not knowing where to focus, and suddenly the virtual image arrives at the eye's "infinity". If the eye does not happen to be focused exactly there when this occurs, and it is likely that it will not, as it will be searching for the view and focusing somewhat randomly in an effort to get the view, then of course the user will continue focusing while the image becomes too close for good and comfortable focus, while the eye figures out what is happening. Then, you have to go back.
So if the last bird you looked at was at a great distance, you have to tell the next close bird to wait, while you focus too close first, then outward, like Seyfried says to do.
At age 59, my eyes have lost so much focus accomodation that the whole bit is pretty much lost on me. My eye just sits there like a paralyzed dummy waiting for something it can see, and doesn't seem to go out of its way to focus too close, or do anything at all. So direction doesn't seem to matter at all to me. Maybe you are young, and still have some focusing ability, and if so it serves you right if it makes your life harder.
