I purchased these binoculars to take with me on an upcoming Alaska trip. I have only had them a short time but the clarity and magnification is amazing. I have taken a few photos from my back porch of birds that are good but will be much better when I mount them on a tripod.

just received this and tried it out, works really well, worth the money if you need this high of magnification

We just love this binoculars!

Works as expected but I wish it had higher magnification.

I’m not sure I have ever seen my 10 year old so excited. He had to start searching inside our house and even kept it in his closet so no one would mess with it.

They are brilliant, I can see so much from this, the conclusion is excellent, really well done, would recommend to anyone.

Compact but super powerful crystal clear monocular for a serious hiker or an outdoor adventure seeker. It's always important for me to have handy binoculars or monoculars nearby to take an exceptional look at nature and our oceans and mountains. Also great for bird watching and sporting events.
K&F Concept has done it with this very affordable monocular right here. This is 10-30x40 means not only can you see the object brightly and clearly, but you can also use the zoom function. With my years of experience with binoculars and monoculars, I'd like to suggest that if you're going over anything over seven power, it's better to use a tripod. Most people blame monocular, but it's actually their hands/body movement (nothing wrong with the product) This monocular comes with excellent built-in tripod screw function. Please see all my pictures and decide for yourself.
Also, I would like to point out that the lens is 40mm with a perfect 20mm eye lens. Even when the sun goes down, you can have a wonderful view because of the larger size of the objective lens. It will take a few times to perfectly open the monocular but it is to be expected from such a wonderful product. Enjoy the sightseeing!!!
PLEASE NOTE: Tripod is not included, but it will fit any tripod. The zoom image I took is only at 10 power. It's my cell phone picture nothing fancy. Amazing right!

PACKAGING The product is well protected from millebole in a box divided into two compartments.
LINKS. It connects easily to iPhone and iPad over WiFi, and connects just as easily to a Windows 10 PC and a Mac with the included USB cable. You can't connect it to a PC on WiFi, or at least I couldn't.
ENLARGES. This tool has great magnification as it can focus infinity and be used as a regular webcam, but can be up to about 3mm from the subject for noticeable maximum magnification. Unfortunately, as is always the case with instruments of this genre, it is misleading to quantify magnification as with an optical microscope, so I'll give a practical example. I connected this instrument to a Mac and photographed a precision micrometric grating for microscopes with an overall length of 1mm. I have a 2160 x 1440 resolution image where the grid is 1098 pixels long and the 10 micron gradation is perfectly readable. On PC and mobile, the maximum resolution for both photos and videos is 1920x1080.
IMAGE QUALITY. The quality is discreet, especially at the core. It tends to deteriorate visibly around the edges. Unfortunately, it only registers in JPG format and the compression artifacts are quite noticeable. But when photographing inanimate subjects (coins, stamps, etc.), you can achieve remarkable results simply by repeating the shot a dozen times and then taking the arithmetic mean of the images in Photoshop.
FLEXIBILITY AND EASE OF USE. If you do not have excessive demands, this small tool is suitable for all kinds of applications: electronics, entomology, botany, philately, numismatics...
It does not require a computer or power adapter, so it can work anywhere conveniently outdoors with just a cellphone to view pictures.
DEFECTSES On the iPad and iPhone 6, the real-time preview appears slightly squashed, but the photos and movies have the correct aspect ratio. All right instead of on computers.
