Handy for older manual film camera with max 1000 or 500/ sec shutter speed to meter in sunny daylight, lens wide open. Metering can be adjusted by turning the ND to meet the correct light exposure at a set shutter-speed and choice DOF (f-stop) combination. Wonderful tool for needle metered or LED array camera where you see the progress of exposure as you turn.

Retractable Rubber hood is the best solution to attach a hood.
Lens cap for a 67mm will be 72mm. I will assume 1 size larger.

I spent a long time buying a filter because on the one hand I didn't know if I needed something like this and on the other hand because I had already tested a 0815 filter with miserable results and the costs for such a part are not insignificant. The question now was whether I should get several filters or a variable filter. In view of the price, the question ultimately became irrelevant. The first tests were able to dispel concerns that the image quality suffers, as with the filter mentioned at the beginning. The images are slightly blurry, but really only marginally. The weakest position extends the exposure time by a little more than 2. In my experiment (Nikon D7200, Sigma 18-35, K&F variable ND filter 77mm ND2-ND400 with adapter ring) I set the aperture to 2 in sunshine. 8 raised to expose well at 1/8000 without a filter. With the filter screwed on in the "MIN" position, the shutter speed went up to 1/3200. I turned the filter from mark to mark and came up with the following shutter speeds calculated by the camera: 1/3200, 1/3200, 1/2500, 1/2500, 1/2000, 1/1250, 1/800, 1/400, 1/125, 1/20(X-Cross, but underexposed). As you can see, hardly anything happens at first and the markings also do not allow any ND value order to be determined, which according to the logic of the first point is 2, the second 4 and the third 8.... So it's time to try it out. In the "MAX" position (1/20) the images are unusable because of the X-Cross, but this is really only the case in the absolute max position, and between the penultimate with 1/125 and Max intermediate positions are also possible where I got useful up to 1/30. So a usable ND value of 266 is calculated. This value is now completely sufficient for filming, because who says that I can't set the shutter speed higher than 1/60, which was the rule of thumb in the early days of analogue filming. Enough theory, I think the filter is an absolutely good investment.
Unscrewing is completely problem-free and if there was a color cast, it was due to the camera (Nikon D7200).
I've uploaded a few pics:
1.) 100% topless bottom view with filter at 5th position (1/2000)
2.) MIN - position
3.) Last usable position
4.) Filter to with X-Cross where the camera with the exposure of my camera (Nikon D7200) failed and I had to raise 2 values ​​in post-processing to be able to recognize something.

I am very pleased with the camera. It has excellent zoom capabilities. If you press the shutter button halfway down, the camera will auto focus. The pictures come out crisp and vibrant. The camera comes with everything you could need: a charger, extra battery, camera straps, and a micro SD card. The size is perfect for me to throw in my bag and capture some shots of my son on the soccer field. Great camera!

We went to Canadian rockies this summer and we were looking for a light weight tripod & a selfie stick to capture our family photos. After researching a few options, we finally bought this. It is light weight, fits in backpack and folds to a really small size. I charged it and paired easily with my Google pixel phone and the remote shutter button worked flawlessly. The remote shutter part can be easily detached and can be used as a small handheld button - which is very useful when using in tripod mode. It's easy to fold, set up as tripod and the grip is firm. Supports good rotations for any angle you want to set. I would recommend this to others, I found it reliable.

This filter is the bomb! I use it in broad daylight to slow down shutter for that cinematic look. My videos have been coming out nice as of lately. This is actually my second time purchasing this same filter for a different camera. Highly recommended for those who want to master their camera & shoot only in manual...

have a very old house and do a lot of DIY work around the house so I actually only have a few different endoscopes which comes in handy from time to time. I love the fact that I can see what's behind the wall or in a pipe without having to tear it down or open it up, which is obviously a much bigger task to patch. I was so impressed with the K&F Concept brand endoscope and when I saw this articulating model I just had to have it and in fact not only is it the best endoscope on the market it blew my mind and saved me a few thousand dollars preventive claims settlement. Please read on to find out how this amazing articulating endoscope has helped me save tons of money. FIRST IMPRESSION: It came in nice retail packaging and inside the box was a sturdy zipped storage case that housed this endoscope in a perfectly fitted shape for maximum protection. The device looks professional and solid in terms of material and feel, which does not surprise me given my previous experience with K&F Concept products. The 5 inch IPS LCD screen is very clear and the buttons are located just below the screen to change setting and mode. DESIGN, SPECS and FEATURES: What really impresses me about this endoscope is not only the swiveling camera head, but also the way the movement is controlled. They really nailed it by using the dial joystick control in the center of the grip so it can be easily controlled with your thumb while holding the grip. Any other design or button would have ruined the user experience, but they really studied and gave the best possible control. Right next to the dial joystick control are the camera button and light button. It takes pictures in photo mode or starts/stops recording videos with sound in video mode. The light button toggles between different preset levels of brightness or turns off the light. Simply brilliantly made and placed in the perfect spot. I also appreciate that this is IP67 rated so it can be submerged under water to inspect anything that contains water and also block out dust or sand. I was impressed with the built-in 3000mAh battery which can last for days if not weeks after a full charge. The beauty of this endoscope is that you can see everything clearly on the 5 inch LCD screen, so you don't need an app or phone to use it, and you can take pictures and videos and then play them back from the device, to view it from the 5 inch screen, not to mention 32GB memory card is included. What's cool is that it also has a WiFi function that allows you to stream what you see on the 5 inch LCD screen to another smartphone or tablet that has the free app installed, so another person can also see what you're seeing, which is really cool. HOW IT CAN BE MORE AMAZING: I really love this endoscope and while this is the best out there I wish these improvements which aren't a deal breaker for me but would only make it more amazing. 1) I wish the cable was longer. It is only 5 feet long, but other non-articulated endoscopes are about 15 feet long. There may be technical limitations to making it longer as it has a moving head, but 10ft would have been better. 2) It would be amazing if the cable could be detached from the device and then attached to the bottom of the handle (current design) or the top of the LCD screen. This design makes it easier to work with the rigid cable, depending on whether you are looking up or down with the endoscope. 3) It would be out of this world if they could make the next model with 360 degree articulation! HOW IT SAVED ME MONEY AND TROUBLES: We recently had a kitchen remodel and replaced all of our kitchen appliances including the range hood. The new range hood we bought was much shorter compared to our old range hood and we can see the opening under the new range hood for venting which we didn't see before on the old range hood. I decided to use this articulating endoscope to check what's behind the kitchen wall and noticed that there was a badly rotted wooden frame due to a water leak from the roof. We immediately hired a contractor to fix the leak, but the repair could have caused a lot of damage and expense if we hadn't known about it years later. I am very satisfied with this endoscope in many ways. CONCLUSION: Easy 10 out of 5 stars. I cannot say enough good things about this amazing device. It's so much better than those endoscopes with two or even three lenses because it's easier to just move the direction of the camera than trying to switch between different camera lenses. It's also much easier to slide and move the cable if you can guide the endoscope's head in the right direction. If you are in the endoscope market, look no further and get this one and it will be worth the investment. Recommend wholeheartedly!

It's thick and sturdy so it doesn't really move when you press the shutter button, so my photos have always been super sharp and not a bit blurry. The bag that comes with it is easy to carry and can be comfortably slung over the shoulder. It is easy to adjust and take off. I'm very happy with it so far
