sakura 30x60 Mini Binoculars Portable Compact Foldable Telescopes Day And Night Vision

I do not know what size of adult is to use these, but I found them small and fiddly, not worth it for me, would not recommend unless for children?

Great value

Love them they are small and compact but they work very very well,and for the price excellent.

Bit smaller than thought but handy for pocket

I started adding a review as a warning to numerous clones of the same binoculars sold under various names, as they all seem to be reviewed by people who either have no idea about binoculars or were given a sample for some reason, or are affiliated in some way, or a combination of those. If you want the quick version of the review, these are toy-quality 8x21 binoculars (no night-vision etc as some listings say) and if you really want them, despite the relatively murky views you will get, find one of the listings that sell them for under 5 quid including shipping. They are not worth more. Over 10 quid and you already start finding other better quality units - no reason to pay for this mis-represented junk.The long version:-They are sold as "30x60" binoculars, which means 30x magnification and 60mm objective lens (although, trying to be clever, the binocular itself says “30*60”). Back to reality, these are 8x21, or 8x magnification, 21mm objective. When buying binoculars a large objective is important because the larger the objective, the brighter the image and it allows a larger magnification, because the more you magnify, the darker your image. 8x is about the maximum you can get out of 21mm binoculars and indeed the image is relatively dark (even darker in this specific set, read on), so 8x25, 8x32 etc will be progressively brighter (but larger). As an interesting note, there are no real 30x60 binoculars. They image would be too dark and the magnification would mean they would not be usable as hand-held. There are 15x60 binoculars though and they weight 1kg and can cost quite a lot depending on the quality.-While these binoculars would have poor image quality anyway due to the quality of the optics, they make them quite worse by adding a red (“ruby”) lens “coating”. I use quotes because actual lens coatings in binoculars aim in reducing reflections and light scattering, so if you look at the lenses against a light source you see relatively dark reflections, much less than uncoated glass, because that’s what they are designed to do. These have some sort of “cool looking” red-orange “coating” which actually reflects MORE light than uncoated lenses! And since it only reflects yellow and red, your image becomes both darker and more blue/green, I would call it overall “murkier”. And yet people, supposedly not blind, will give 5 stars saying these are great at any price! I tried to show the effect in a photo, read below. Mercifully only one lens surface is covered, the rest are completely uncoated, which normally is not good, but in this case we saw it could be worse!-Some listings actually say these are “night vision”, or even “infrared”! Blatant lies of course. You can use them at light to look at the moon, or something under a streetlight, i.e. where there is light, but as I said they are quite dark, much darker than the naked eye, so if something is not well lit or bright (like the moon), you will actually see worse at night with these than without them!-They are listed as 7.2 degrees (126m/1000m) field of view, which is not bad but, sadly, I measured them to actually be about 6.3 degrees (110m/1000m) and even worse with a very small eye relief which means you have to sort of stick your eyeball to view the whole field (forget about using glasses).As illustration points I include two pics where they are compared with a (still not expensive - about 30 quid on sale) more “substantial” 10x42 binocular. In the first image you can see the comparison of the objective size and also note the reflection due to the coatings, a lot of yellow/red light is reflected!In the second image I tried to take a picture with a DSLR through each binocular. The quality is not that great since it is hard to get results with the afocal method using a binocular, so they came a bit blurry, but with identical settings they are a good indication of the relative brightness and colors. So, in the 10x42 unit you see a relatively bright image and nice colors, with the “30*60” you see a quite darker image that is bluish/murky, there is no saturation in the yellows and reds. Generally, if it is not bright outside they are not that pleasant to work with. Unless they were given to you for an honest review, in that case they are always pleasant.To reiterate, there is nothing better that I can recommend under 5 quid, so for the few listings where this set is at that price, I’d say get this toy if that is really your budget limit. Some units have been reported to break immediately or come mis-aligned (you get double-vision and no, it is not as cool as it sounds, you have to send them back), but otherwise you are OK if you avoid the more expensive listings. The advice of course, if you actually want binoculars, is to go a bit higher on your budget and take note when there are dubiously “honest” reviews…

Very compact and easy to focus
