Hello everyone! Hope you enjoy your monocular life. I have some information for you today. This monocular isn't bad, but I was concerned about backlight flare. So I decided to install a hood. Let's finish. 54mm, folks! The 54mm fit perfectly! The body's rubber cover was moved slightly to reveal the screw hole at the top and a 54mm to 55mm step-up ring was fitted. (... It fits my case smoothly, but please do so at your own risk.) In my opinion, the flare seems to be much better and the sharpness of the image has improved. I would like to think that the effect was more than investing less than $10 and risking losing some portability. And what's more! You can use CPL filters and all sorts of other filters as many times as you like, and you can potentially attach a teleconversion lens to play with, although I doubt it will work properly. It's a dream come true... Uh? Am I the only one dreaming like this? In the meantime, I've uploaded a photo of an attached 55mm camera lens hood if you'd like to take a look. Also some cute birds. ▼ ▼ ▼ ▼ ▼ ▼ ▼ My hobby is observing and photographing wild birds with monoculars and smartphones. Sometimes I use a tripod, but I prefer handheld when possible. I used Nikon 6×18ED but it was too dark. So I bought this one which uses a 50 diameter ED lens. The 50 diameter lens size was very effective for my purposes. Bright! It's bright! Unfortunately, the chromatic aberration was quite large and the effect of the ED lens was not as high as I expected, but maybe my expectations were too high. Or maybe the price is right. As you take darker images, the aberration becomes much less noticeable. It is still in the testing phase, but you can check it in the attached photo. I think it's a good value monocular for those who think this level of photography is sufficient. I'm also happy with the price. However, I plan to test it with the [Opticron dba vhd+ 10x42 monocular] or [VANGUARD VEO HD2 1042M] for another jump. What? Are you saying it's wiser to buy a good camera? Ha-ha-ha-ha! I used the Huawei P30 Pro. The video was recorded with the standard lens, and photos were taken with the 5x telephoto lens. (Standard lens is 500mm with digital zoom x 1.6, telephoto lens is 1620mm) Slow motion shooting is recommended as handheld video footage can be blurry. It's also useful to use a dot sight together, even if it's a cheap sight. It also makes it easier to spot wild birds if you're spotting them. Well, I wish you all a better monocular life!
