I am still new in bird watching, and so far I mostly used other people binoculars to watch birds. I am aware that for birding it would be best to take some bigger binocular like 10x50, 10x40 or something, but the thing is... whenever I go on some bird-watching field trips, I always have my camera around my neck, and it is already heavy to carry around... so I was thinking about purchasing some small binloculars like 10x25, or 12x25 (that would also be handy to carry around in my backpack every day), but I have no idea are they any good for birding, or I will just waste my money on something like that??
I saw in some local store:
Practica 12x25 S
magnification: 12
lens: 25 mm diameter
eye ring diameter: 2.08 mm
brightness: 4.33
twilight factor: 17.32
angel of view: 3.8°
field of view in 1000 m: 84 m
focusing distance: 6 m to infinity
weight: 225 g
and
Practica 10x25 S
magnification: 10
lens: 25 mm diameter
eye ring diameter: 2.5 mm
brightness: 6.25
twilight factor: 15.81
angel of view: 5.8°
field of view in 1000 m: 96 m
focusing distance: 4.5 m to infinity
weight: 200 g
... but I have no idea what some of these specifications actually mean? So any advice is most welcome. Thanks in advance!
