The Celestron Nature DX ED 12x50s are compact and portable, but some high-end glass makes these binoculars a serious step-up option.
Roof prism binoculars like the Nature DX ED 12x50 exist because they're more compact and easy to travel with than porro prism binoculars, and not because they transmit more light. They don't — which is why the phase-coated BaK-4 glass roof prisms and the ED make a big difference.
ED glass works really well. Its 4.8-degree field of view constitutes an incredible close-up when viewing objects in the distance, with a trip to see some motor racing heralding bright and sharp views even in the distance. That applies to dusk, though it's at night that we were most impressed by the Nature DX ED 12x50.
The Nature DX ED 12x50s' 2m/6.5ft close focus was most helpful in our backyard, where we could observe wood pigeons and sparrows from close range. The views are always bright with plenty of contrast.
