Here's a link that might help explain. http://www.bigbinoculars.com/nozooms.htm
I have tried a zoom also and they are junk. I would like to see one made with only one eyepiece that zoomed. You could always close one eye when zooming, but at least you might have a zoom capability that would be better than trying to zoom both eyes.?

Reduce field of view compared to normal/fixed bin.
Increased weight.
Excessive magnification (usually) meaning a small exit pupil

For birding the magnification depends a bit on habitat but 7x to 10x works well.
hello everybody,i have recieved binoculars,its great bins,clear and sharp images. only problem is that its out of collimation if u zoom it at 15x power....a little bit not too much as u can see double images....its ok at 12x zoom.its really new as shown pics.will use as 7x power lol...i m satisfied and will keep it and some day will have 20x fixed zoom bins....insaAllah.....thank you all....

This reminds me that I have a Japanese made 20-135x27mm fully coated optics binocular. It doesn't have a tripod mount option. Unable to find online so it must be "rare" :flyaway:
