needed an endoscope camera because I wanted to determine where power cables were running under our false ceiling. Teslong's camera came at just the right time. The Teslong device comes in a sturdy hard plastic case. The scope of delivery includes the handheld with a 4.3" display, a 5 meter waterproof camera hose (with triple camera), a device stand, USB-C data cable, various attachments for the camera, a 32GB micro SD card, a mini Allen key and instructions (incl. German language).The camera is securely attached to the handheld and can be removed using a mini Allen key.The connection of the camera hose then turns out to be a USB-C cable (whether this can also be connected to other devices I couldn't check whether it can be used in this way). I was immediately enthusiastic about the model, since it comes with a self-sufficient handheld. I already had various endoscope cameras. However, they always had to be controlled using an app (sometimes not very trustworthy ones). Depending on the Android or iOS version, it was not possible to get the cameras to work at all and it is also not possible to handle a notebook in a narrow corner t that simple. So a huge plus point for the Teslong camera. The battery was already pre-charged and the SD card was already inserted and pre-formatted. So it could start right away. The camera hose is relatively rigid, so you can drive through longer pipes or areas that are difficult to access. The rigidity meets my taste. In the past, cables were relatively thin and most often snapped and jammed immediately after entering a choke or duct. The device itself is comfortable to hold and easy to use. The buttons are large enough to operate the device with one hand and guide the camera with the other. During the test, I stood on a ladder under the ceiling and inserted the camera through a small opening in the ceiling light (diameter of the camera housing approx. 8.5mm). Everything is easy to see on the display and the pictures taken also correspond to what is shown on the display. The built-in LEDs are great and also illuminate a pitch-dark area well. The camera can be switched 3 times (to the front, to the left and to the right). In this way, an area can be viewed almost 360° without rotating the camera tube. There is also a 2x digital zoom with 1.3x and 1.5x (although the quality of the image decreases here, mostly due to the poor illumination in a dark room). The handheld also has an LED installed in order to get a good picture of the insertion opening even in a poorly lit area. Conclusion: I am totally enthusiastic about the device and it exceeds my expectations. I was able to do all the work I wanted to do with it with no problems (I found all the cables I was looking for in the ceiling). At the beginning the price seems a bit high, but you get a top device that is super processed. Simply unpack and start looking: no more installing apps, looking for adapters for your smartphone or sitting in a tight corner or niche with a bulky notebook, thanks to the self-sufficient display. The pictures taken in HD quality are great and the endoscope can be used very flexibly thanks to the 2 cameras. For home use, there is a clear purchase recommendation.

This is amazing, really cheap and really good, high-quality glass, I accidentally dropped it and it didn't even have a scratch! works very well, and the ring isn't too loose. However, if you tighten it a bit to much,it will be hard to remove.
Recommend using a rubber band to remove it in that case,
although it is very very good, recommend it 10/10, you won't be disappointed!

I've tested quite a few endoscope cameras, all of which were junk. With this camera you get a reasonable quality that you can do something with for a relatively low price. In addition, there is the very chic and nice hard case and the accessories. I highly recommend this product!

As a Professional Photographer and now moving over to Video as a Hybrid Shooter and content creator I have a growing number of new Professional mirrorless cameras & lenses. With many lenses of different diameters it is first and foremost important to protect the lens elements from damage. Then decide on what specialty filters that will help you with your composition & image making. From UV, circular polarizers, and Neutral density filters, K&F Concept Professional Optics makes great glass. In my many years of use of different brand name filters, it is my opinion K&F Concept will give you the BEST bang of your BUCK. Buy one today, try it out and see for yourself!

Really balanced out the picture for our church livestream, we have all LED lights inside.

I have tested the endoscope extensively. the enduscop has saved the need to remove parts in the automotive sector. I didn't expect to get so much quality for the price.

I shoot photography semi professionally and needed a good CPL after watching YouTube reviews I popped on this for my canon t7 with EFS lenses it disappeared perfectly, stays on (sometimes to good can be a lil tough coming off), picture quality is great (I run manual always), hasn’t scratched or discolored yet it’s been like 2 years almost with near daily used mainly in the woods/nature, threads are okay that’s probably the only “2 complaints” if you’d call them such I have, first the lens cap (stock canon 58mm) do not hold onto the CPL so travel with caution and keep tabs on your lens cap or you’ll be buying more! And second it binds a little going on every now and then if they’d clean them up a shade and maybe get lens caps to hold tighter for travel this CPL would be and really is the best bang for the buck in my eyes! Yeah you can buy crazy expensive stuff but on a budget for non pro use definitely get you one! Once I finally do this one in I’ll be buying another. Oh and super important it comes in its own hard case for storage/travel with foam and it locks shut so it’s safe, I’ve had it in my camera bag and climber mountains and it’s stayed in the case no issues that’s definitely a plus i needed to mention.

High quality and very affordable. Does a great job at cutting reflections. I don’t go anywhere without this filter anymore and I’m honestly wondering how I got by without it. Highly recommend this filter.

THREAD SEEMED MACHINED CORRECTLY, GOOD FIT ON MY 150 TO 500MM SIGMA ZOOM. i FOUND NO ISSUES WITH AUTO FOCUS WHEN PAIRED WITH MY NIKON Z7. POLARIZATION SEEMS EFFECTIVE AND i HAVE NOT NOTICED ANY DISTORION.

I bought this 95mm CPL for my Tamron 150-600 lens. Being new to big tele’s, I foolishly started with a cheap $20 CPL (Altura, if you must know). The auto-focus simply would not work with this filter when the lens was cranked beyond about 300mm. So the local camera store sold me a ProMaster CPL for $270. That performed perfectly, but unfortunately it got broken, although happily it kept the lens from being damaged. Not wanting to spend that kind of money again, I decided to try the K&F Concept CPL for a mere $59.49. It performs perfectly at all focal lengths, getting images every bit as tack-sharp as with the filters removed. Great sky darkening and reflection control!
