The 10 weighs 23.3 oz. with 15mm ER, 6� angle of view and the 8 weighs 22.9 oz. with 19mm ER, 6.3� angle of view. The 8 is not a wide field of view binocular
However, it should be noted that while the Olympus 8x42 has a FOV of 360.7 feet at 1000 yards compared to the Swarovski EL 8.5x42 of 390 feet which is only slightly less, the Olympus 10x42 EXWP1 binoculars exceed by a slight margin the FOV of the Swarovski El 10x42 binoculars (344.3 feet at 1000 yards for the Olympus versus 330 for the Swavorski.) So all in all the Olympus binoculars are in good company even considering that the Swarovski has a magnification of 8.5x versus 8x for the Olympus. Overall, at 1000 yards the FOVs are only slightly different for the two sets of binoculars.
