I stuck this zaino to need to quickly hold and pose my reflex.

The "K&F Concept 67MM Polarizing Filter Circular Polarizing CPL, Ultra Slim, Japan Optics, Multi-Coated, with Lens Cap" came in a branded box. It was nice to find the filter in a hard plastic case for protection, with a lens cap already attached to the filter. I ordered this filter for a Nikon P900. With the lens cap still attached to the filter, I carefully screwed the thin filter into place. I then took a series of pictures to check its effectiveness, and have included two pictures of the original Nikon lens cap showing the difference. When attempting to remove the filter, I found that it was stuck, so I had to resort to a filter wrench to remove it. The reason it got stuck was because I was turning the polarizing ring clockwise and counterclockwise from my perspective behind the camera. I must have just caught the threaded ring with my finger as I turned it counterclockwise, just enough to lock the filter in place. Some suggestions I have from using the filter; 1. When installing the filter, leave the lens cap on as it gives a larger shooting area. 2. Only turn the filter clockwise when viewing it from behind the camera to avoid repeating my mistake and lock the filter in place. 3. Carry a suitable filter wrench when using one of these filters just in case it gets stuck. 4. If it fits a P900 and it gets stuck. Zoom the lens so it points out about 30mm then remove the battery without turning the camera off. This will stop the lens retracting when the camera is off and if the camera is left on it will stop the lens trying to counteract the movement. 5. The lens and cap are stored in a small cellophane sleeve inside the plastic case. It is best to leave the lens cap on and insert it so that the flap of the cover is on the same side as the lens cap. This virtually eliminates the risk of the sticky flap touching the exposed filter surface. The only thing that would make this filter better is some sort of cover for the exposed surface or attachment points to hold the filter in place inside the case.

It may seem a little bulky, but no different to having a GoPro stuck on your lid, The camera is amazing good colour and stability, you can take a picture if need be with the click of a button. The quality of the picture will not disappoint. the intercom is clear and got some nice bass when listening tp music, and clear voice when using sat nav, or talking to the pillion or fellow rider..
It feels well built.
Easy to install.
But with something so good there has to be a down side, which is you only get the hard mic with the unit you have to order the soft mic separately, but there not that expensive, and the app is easy and good to use , but don't expect to see what you recorded through the app as it takes forever to load. Easier to eject the memory card and plug in to the laptop
Two minor issues compared to everything else being really good.
Good buy not disappointed at all.

The microscope works well enough focus is a little rough. It has a good clear picture and the side lighting is a real help. The power button on my unit was stuck down when i first powered it up so it just was stuck in a start up -shut down mode until i freed up the power button then all worked as it should. I would like o try the remote control but it did not come with a battery and no listing of what battery is required. Over all i like the unit and for the price it fine.

Genuinely impressed with this little microscope. I'm absolutely stunned at the image quality for such a small cheap device. Highly recommended for anyone with kids who are interested in science, heck, even for yourself.

It comes with a lot, more than I expected (I admittedly did not read the listing as close as I should). The microscope slides are an excellent touch, giving you something to practice with right off the bat. You have a dial to magnify the image and a second dial to focus, and a built in light. It works so well. I did my best with a picture, but it doesn't do it complete justice (that blemish is on the slide, not the microscope).

I love the portability of this one and the versatility of being able to use it on many surfaces/objects. As an avid stargazer, I'm appreciative of the functionality of this one at the micro scale. Some pro tips for use, I noticed that it seems to be a mirror image, something I'm used to with a reflector telescope. So you may need to move the microscope down for the image to go up. Keep in mind that this magnifies big time, so tiny slight movements go a long way. Also, don't try to completely unscrew the battery cover screw. It is actually very short and I think is only on there for added protection as the battery cover itself seems to lock in securely.

Looking at the cloth it came with and the instructions were pretty wild. You can see the fine weaving of the cloth and the red/blue/yellow dots on the print. Very cool stuff, hope you enjoy it as much as I do.

Works great as a one stop shop variable and for your camera. The polarizer can sometimes get stuck, making it difficult to rotate while it's on the lens.

I simply copied the complete text from my YouTube video for you. Who prefers to see the video "Dji Osmo Action 3 I without ND filter in automatic mode and in PRO mode?" Enter on YouTube. Why do you need filters? It's a valid question, of course, who hasn't asked themselves that? I think everyone has stumbled across this topic and this question... The answer to this is very simple and surprising in view of this video - No, you don't need filters on a camera, it works without it...***but...It would be more an advantage as a disadvantage to have and use some. Anyone who works a lot on the water and beach, like me, or of course, like most of you, vacations there, quickly learns to appreciate filters. First, they are a very good protection against dust or sand from the beach. Of course, a filter also protects the lens, the lens in the camera. So much for the obvious, but the main job of a filter is to let less light through onto the sensor, it's like putting sunglasses on the camera. This has the advantage that longer exposure times can be achieved. It helps the camera to adjust and react faster in automatic mode when controlling the exposure time or white balance. Or if you prefer to work in Pro mode, you will quickly find that the exposure, the shutter, generally works better. In general, filters make the water smoother, and there are also fewer reflections. Or if you take great landscape shots, the sky immediately looks a little bluer. Filters also enhance the colors generally, making them more vibrant. DJI has, in my opinion, excellent colors and that in connection with a filter automatically makes the recordings **//LVL UP. This saves you having to color the film material because it comes out of the camera almost finished. Of course, the full professionals among you have other requirements and such, but I'm talking here for the normal user, like you and me... There are different ND filters. It starts **in my set at ND 4 and goes up to ND32. The ND4 filter lets only ¼ of the light through to the sensor and the ND32 filter 1/32. I use my filters like this... in the morning ND4, towards noon ND8, noon to afternoon ND16 and afternoon to late afternoon when the sun is very high ND32, and then in the evening just before the golden hour I go down again with the filter strengths. Over time, you will figure out when and where which filter is best used, is not witchcraft, even if many want you to believe that. Especially in summer or in winter when there is snow, I think it should at least be almost mandatory to have ND filters to have. If you like to film in Pro mode and work a lot with it, it is almost a must to work with filters alone because otherwise you cannot work with exposures in a meaningful way....
