As far as being able to hold 15x binoculars steady - you need to try it for yourself. I can and have used them in certain situations as my sole binocular, but most are not able to hold 15x binoculars steady enough to use them practically in the field. 12x is too much for some people. It’s an individual thing and must be tried before committing. 15x binoculars are also heavy. The weight to me helps to keep them steady, but it also will tire you out quicker if your holding them unsupported and the shakes will get real bad then.
I run Swarovski 15x, but have looked through Meopta 15x binoculars before and found them to be nearly the equal to my Swarovski for much less money.
