While searching for specs suitable for bird watching, I arrived at the specs of 8x25. If you use the almighty 6x30-B+, you can fully enjoy observing nature such as wild birds. Also, for beginners in bird watching and those who photograph wild birds, a 5x21-A5 lens with a wide field of view is a very convenient tool. However, as you enjoy more serious observation, you may find yourself wanting a little more magnification. In fact, 8x binoculars are probably the most used for bird watching. Considering the Hinode lineup, it might be 8x42-D1, but... 8x42 is a common spec, and many people still consider 8x42 to be the standard for bird watching and nature observation. However, in fields such as bird watching events, the most common spec is 8x32, which has a 4mm pupil diameter. If you're not that concerned about it, 8x32 will probably provide enough brightness. Hinode Optical also sells the 8x32-T1 binoculars for bird watching as the previous model of this T2, and it has been very well received. Hinode 8x32-T1 Meanwhile, enjoy nature observation with the 8x25 pupil diameter of 3mm.
People came out too. I guess its compactness is appealing. Thanks to coatings that have evolved greatly over the past 30 years, light transmittance has increased significantly. Users are probably also realizing the benefits of the advanced coating. Of course, there are individual differences, but when it comes to brightness, Hinode Staff's experience is the same. If the binoculars have a sufficiently good coating, you will hardly feel any complaints about the lack of brightness even with 8x25 (pupil diameter 3mm). The 8x32 spec weighs around 500g in most cases, which interferes with footwork when observing while walking. On the other hand, there are not many situations where the brightness of a 4mm pupil diameter is beneficial, such as in the forest at dusk. In that case, whether to choose 8x25 (pupil diameter 3mm) or 8x32 (pupil diameter 4mm) is a matter of usage and preference.
