I bought the backpack for a Canon EOS R and a Nikon Coolpix P950. Both cameras, various lenses, spare batteries and chargers have enough space in the backpack and, if necessary, the compartments can be rearranged thanks to the Velcro.
The backpack makes a solid impression and the zippers work perfectly.

The 'K&F Concept 67mm UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter with Lens Cap' arrived in a branded box.

The lens is in a plastic case for protection, it also serves to protect one side of the filter, whilst the opposite side is protected by the lens cap.

The filter was an easy fit to my Nikon P900 and as it is slightly wider than some filters I found it easy to unscrew after use. I would however recommend carrying a suitable filter wrench just in case.

It would be nice to see a cover for the side of the filter not protected by the lens cap a the lens filter with cap attached are stored in a cellophane envelope in the case, I suggest putting the filter/cap combination into the envelope with the lens cap the same side as the flap which keeps the adhesive as far away from the lens as possible.

It would be nice to see a protective cover for the second side of the filter, maybe something push on.

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.

I like this camera it comes with a case.

Purchased for use on a Nikon Coolpix P1000 the filter fits perfectly to the thread on the camera lens. The materials and the quality of the filter can be perceived both by sight and by touch. The filter itself is equipped with a thread where additional filters can be mounted.

Protection for P900 lens

great product, cheap and well made. It works perfectly. If you have lenses (pre 1977 Nikon in my case), calendar dates but very current quality as in my case...then this product is for you. On the other hand, if you have more modern lenses than where you don't want to lose data transfer between the lens and the camera, then you need a different adapter.

I was in need of a 82 MM PL filter, I wanted some ND filters so when I saw both at a lower price than the PL alone for the name brand I usually buy I was interested. As someone who spent years selling photo equipment of the pro level to pros I want quality. using with two high quality lenses the Nikon 105 1.4 and Nikon 80-400.
Starting with the packaging the box was first rate, not just a cheap white box. The filters came with a case and I was expecting a wallet style, nice but inexpensive and I was please to see a high quality plastic case that provides better protection to the filters. Best designed case of it type I have ever seen, Thin design but thick strong plastic and with a unique rubber grip bonded in to allow filters of any smaller size to be securely held in place.
While the packaging an case are important the real deal is the product itself . When I opened them I didn't immediately identify the PL as it was the same thickness as the ND filters. Most PL are thicker because of the rotating nature of the filter which can be a problem with WA lenses. Thin often equal flimsy but not in this instance the metal rings are of high strength , the filter rotates smoothly and are of good optical quality.
A problem often encounter with PL filters is difficulty removing the filter, especially so with thin filters as pressure to the sides of the filter in removal will cause a filter to be temporaryly out of round and bind. With standard filters you apply pressure with the palm to remove the filter but that is not possible with a PL due to it's rotation. The thinness of the PL makes it difficult to just apply pressure to the sides and they have very thoughtfully made the two rings slightly different, The outer ring , the one you rerun to vary the effect of the PL is smooth, the inner ring has machined finish with narrow grooves that you can easily turn with a fingernail, a great solution . Of course part of easy removal is not to torque it down, it doesn't need to be tight.
Dont frequently review products but his is one I strongly recommend, especially at the value pricing.
