I can confirm there was no black X mark on the images, works very well with my lenses. Make sure to remove the protective UV filter on your camera if you have one otherwise you will get some vignetting on the raw photo (which can obviously be adjusted post processing but it always good to have it done correctly first as it will save you time). I am using this filter on my 17-40mm and 24-105 canon lenses and it works perfectly with both of the lenses. I bought the 77mm version and it is definitely worth the money. Will give you some great shots in the daytime of waterfalls if you are into nature photography. A must have for long exposures.

There are many differnt brand out there, recently K&F has become one of my faverate choice for the VND. Ever since I bought their 67MM VND. So far it works great on my lens, the picture quality is good, and so is the build quality, too. and doesn't break your bank like some other brand.
This time I got this 62MM VND8-128, same build quality, and I expected the picture quality is going to be the same as the other size. It also has the hard stop to provent you go over the stops , so no X cross.
I will be using this VND in my future vlogs, and vidoes.
tho the price is a bit higher than the one I bought before, I wish the price could be even better.

well worth the money. quickly delivered... pair this with a set of step down rings to cover all of your lenses, and you have the perfect enthusiast nd filter set up...

A very nice ND filter for the price, no noticeable effect on sharpness for video work (though not tested with high resolution photography) and minimal issues with flaring in bright sunlight so the coatings work quite well. As long as you use it within the specified ranges you won't see the typical X pattern of variable ND filters. Does what it needs to do without detriment to image quality, which makes it a pretty perfect filter for the price.

I am using it since a year and I very happy

The ND8 to ND128 filter covers a very useful range. There is no visible banding and very little colour change. More test are required to determine the performance in greater detail and different conditions, but I am impressed with the initial results, which show good consistency and accuracy of markings on the filter ring.

Great bit of kit cuts out all the Pfaff of keep changing lenses

ordered the Teslong endoscope camera for examining hard-to-reach places. Since I will probably only use it a few times a year, it is perfectly adequate. You can't just compare them to a professional device. It comes in a handy storage case with foam inserts. Operation is clear, self-explanatory and the display is easy to read. The first thing I checked was the drain in the bathroom sink, because hair often gets tangled up in it and clogs it. I have to disassemble and clean the siphon regularly. Now I can inspect the drain with this camera and use the hook to remove any hairballs before they become a problem. After a bit of experimenting with the LED lighting, I got quite good and sharp images, on which you can also see details. The brightness can be adjusted in 6 levels and is completely sufficient. The recordings are stored on a supplied 32GB SD card and can therefore also be viewed later on the PC. The flexibility of the probe hose is pleasant and not too rigid. However, it is difficult to steer, so that it sometimes takes a few tries before you hit the desired position. It can take a while, especially over long distances. The additional lenses are very helpful because you don't have to work with a deflection mirror, as is the case with some competing products. I have no complaints about the processing. There are no sharp edges or burrs.

This very light and compact endoscope camera comes in a hard case with a foam interior. The cable of the camera is about 5 meters long and has a diameter of 0.5 cm. Contrary to what is stated in the description, the camera is not equipped with 6 LEDs, but with 8. 6 LEDs light up on the front of the middle camera. 2 lights on the sides, each on the right and left. Cameras are also installed here. So you can look down (into the combustion chamber of the cylinder, for example) or switch on the camera on the right or left to look at the walls without having to turn the camera. Very good. The camera has a resolution of 1080p, i.e. Full HD, the recordings are stored on the 32 GB memory card supplied and can be called up at any time. The 4.3 inch display is equipped with hardened glass and is easy to read. The menu is tidy and logically structured. The language, resolution of the recordings, etc. can be set here. There are other LEDs on the side of the device that can also be turned on to act as a flashlight. The integrated 2600 mAh battery is charged via USB-C charging cable. A good choice for hobbyists and mechanics.

Item was delivered very quickly and neatly, item was then inspected. Everything was actually already assembled, memory card was inserted, endoscope already assembled and accessories such as Allen key, small spare screw in a small plastic bag. Switched on, battery and was almost 100 percent charged----- ready for use immediately, endoscope actually very rigid and the function of the LEDs as advertised or advertised. The LEDs on the side can only be activated, as can the camera switchover to the left / right view, by pressing the small push button on the endoscope (USB port on the camera). Provide the screen with a protective film and everything can be stowed away and protected well and securely in an associated case. Image quality for close-ups acceptable to good, but editing options to improve quality .... you can still get a lot out of it using an image editing program (but that's not a point of criticism for me, just a comment) .... but completely sufficient for a quick snapshot, inspection / assessment or short video sequences. USB connection fixed on the camera with a small screw, also has a reason because the cable is a bit rigid, it protects the connection in the camera from accidental loosening or breakage. The small support foot that you can attach to the camera is well intentioned but somehow not fully developed, unless you don't move the endoscope cable anymore, otherwise the camera actually does what it wants....slips back and forth or possibly falls .down Camera settings such as date, time, language, etc. can be set quickly and intuitively. Manual available ..... But you should take the time to check all the functions and familiarize yourself with the camera. If questions arise, the customer service provides or offers very fast and friendly support in a short time.....Great If the quality and customer service remain the same, which I hope, the camera is a clear purchase recommendation for me
