Q1: Are these binoculars considered Night and Day ? The Trooper 10x50 DPS I . Thanks, Hector.

A: These are not a night vision binocular but because of the large objective lens size they work very well in extremely low light situations.

Q2: 1)The picture of DPS I 10x50 seems to be of the pic of 10X50 DPS-R Series, Pls clarify ! 2) How good is the 10x50 for Bird Watching ,How good it is for watching birds in Evening ? 3) Does it have Lens coatings & Ajustable Eye pieces ?

A: the DPS R was discontinued by Olympus and the DPS I is the replacement version they are basically the same binocular with a few optical differences which is why the image looks the same. It is a nice binocular for birdwatching though an 8x40 tends to be better due to the wider field of view. The lenses are fully multi-coated and they have twist up eyecups.

Q3: What material are the prisms made of?

A: Unfortunately, we're not able to provide that info. Olympus does not specify the type of glass or other material used in the Porro prisms of these binoculars.

Q4: I would like to know the weight and the measures of this binocular?

A: Weight of the Olympus 10x50 Troopers is 28.6 ounces; dimensions are 7.2x6.7x2.8 inches.
