In search for compact yet powerful binoculars

I am on the market to purchase binoculars. My requirements are:
- Waterproof
- Soft and smooth zoom and focus function, "one-finger operable" so to speak :)

So the following list might be helpful if you are looking for binoculars too. I was choosing from these models:

- Barska 12-60x70 Escape, advertized as better than “Barska 12-60x70 Gladiator”

- Celestron 20-100x70 SkyMaster

Celestron 25-125x80 SkyMaster

- Vivitar 20-100x70 HD Zoom

- Sunagor 20-100x50 Mega Zoom, Sunagor 30-160x70 Mega Zoom

- Sunagor 15-70x27 Maxima, Sunagor 25-110x30 Super Zoom
http://www.sunagor.com/acatalog/pocket-zoom-binoculars.html



And, the winner iiiiis: Sunagor 25-110x30 Super Zoom. Compact size and super-zoom won the prize. Probably its shitty quality on the far end of zoom, but I wont make award winning pictures through it anyway
