These are my favorite binoculars of the ones I own, but it took me a while to get used to them.
Whenever you increase the power of a pair of binoculars it reduces the field of view. That makes It a lot more difficult to learn to find things that you want to see.
I purchased these because at the time they were the smallest and lightest binoculars of this power that were available. And I had a lot of confidence in the Pentax name. I have not been disappointed.
Although there a number of mini-binoculars that are available for hikers that are smaller and lighter, I don’t know of any with this power magnification, which I refuse to give up.
As with any binoculars the first number 12, is the magfification. The second number 24, is the size of the light gathering openings in millimeters. The field of view of these at 1000 yards is 262 feet. (This is a 5 degree field) These cannot focus on anything closer than about 12 feet.
The way I finally learned to find things is to carefully observe a visual “pathway” to my intended target. For example, to see a bird I note with the naked eye what the base of the tree looks like, the characteristics of the fork I want, and some possible way to tell how far out to look. Then by “sweeping” my view through the binoculars along that visual path I can usually find what I’m looking for pretty quickly.
These have been quite wonderful to check distant road signs, or to hunt for trail markers, as well as wildlife observation. At 10.2 ounces, they are a little more weight than I wish when backpacking, but we seem to use them on every trip, so I just can’t give them up.
The specifics- they are Uni-barrel, center focusing. The lenses are multi-coated. You can spread the body for easy eye width adjustment. There is a diopter adjustment (the small button at the top of the view that shows the eyepieces). You depress it once and it pops out. Then you can adjust the diopters to your own eyes, and pop it back in. This is supposed to make it so that they don’t get knocked out of adjustment easily. In reality, it gets bumped and popped out all the time. I can’t tell by looking at the picture of the current version of this model if they’ve fixed this issue or not.
There is a thin nylon neck strap that is adjustable, and the binoculars balance well on the strap. The carrying case is nylon and vinyl. You can close it around the binoculars with the strap still on for carrying around the neck, or there is a belt loop on the back of the case.
I see that the current version of this model is only 9 ounces, but the cost has gone up to $149.00.
If you want high power binoculars without a great deal of bulk, you can’t go wrong with Pentax.
