I love the night vision binoculars

At the moment there are a lot of monoculars coming onto the market, almost all of which are made in China and hardly differ in terms of quality, scope of delivery and price.

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!

The first photo was taken straight out of the box at ISO 3200, f/8.0, 1/60 second with flash. The lens produces clear, sharp RAW images (Nikon NEF) and shows little distortion. The second photo was taken through a layer of Plexiglas. The lens is good for portrait, landscape and macro. At 35mm f/2.0, it's fast enough and wide enough for underwater and astrophotography. When you capture RAW images, Adobe Lightroom doesn't recognize the lens, but it does profile it if you enter the information manually. This is a great addition to any photographer's kit. Being inexpensive is an added bonus.

There are cheaper and more expensive monoculars. Since I only want to use the monocular every now and then, I didn't want to spend too much money. So I first ordered one with comparable features to this one, but about 20 euros cheaper - and immediately sent it back because of the extremely toxic smelling plastic housing. Then I looked around again and came across this monocular from K&F, which at around A$73 was significantly more expensive than the first one, but still cheap compared to other devices. And this time I was not disappointed. Not only does the materiel not emit any odor - it also looks much higher quality overall. Image & magnification are completely fine for me. And the mobile phone holder is also really practical:
I removed the wrist strap again because the monocular doesn't fit properly in the bag that came with it. That's a shame, just a few millimeters more air would have been enough.
It is just as unfortunate that the cover of the outer part, in the lower part of the lens, is not connected to the housing and therefore always has to be stowed away in some jacket or trouser pocket when in use.
Conclusion: The price/performance ratio fits, purchase recommendation!

I tried them twice and they worked great. On a very bright day with the ND64 I was able to shoot at 60 fs, as they were polarized it gave the shot very good contrast.
A great product that comes in a useful, quality case. Perfect combination of ND options.

The adapter can be easily used on both the camera (450D) and the lens (Tessar 4/135 from CZJ). The lens is about 60 years old and I was curious to see if it would still be possible to take pictures with it. This can be confirmed with "yes". Of course you have to do without automatic functions, you can only do it with manual exposure and focus adjustment, as it used to be. As far as the connection to the camera or lens, which has been mentioned several times, cannot be separated again, minimal lubrication BEFORE first use is announced and solves this "problem" before it arises.

This monocular is very nice for the price that you pay. I have a couple Vortex monoculars and i can say that they are close to quality and clarity to the Vortex optics. Having the monocular be nitrogen purged to prevent fogging up is a very nice feature that comes in handy. Highly recommend!
