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.

I got this for several of the 52mm lenses I have. It threads on smoothly with no wobble and is made of nice, thick plastic.

One of these lenses is a 18-55mm zoom used on a Nikon DSLR with an APS-C format sensor. The manufacturer’s description says not to use this hood on any lens with a wider field of view than 25mm to avoid vignetting (darkening of the edges of the photo). The crop factor for Nikon APS-C sensors is 1.5x, so at 18mm this lens has a field of view comparable to 27mm on a full frame digital camera or a standard 35mm film camera which is usually used as the reference when describing the field of view of lenses attached to cameras which evolved from 35mm film cameras. Look it up to get a better idea of what I’m talking about if you don’t already know. I’m not that keen on it myself.

Anyway, 27mm is uncomfortably close to 25mm so I ran some test shots of an evenly lit yellowish blank wall with the Nikon to check for any vignetting. The camera viewfinder is not 100% accurate so I had to go with the actual pictures. I found no noticeable vignetting at 18mm as long as the hood was oriented with the two largest “petals” pretty close to 12 and 6 o’clock. I found that to achieve the no-vignette at this position, the hood needed to be screwed in all the way – meaning that the lock ring had to be all the way snugged up to the body of the hood. A partial rotation of the ring to secure the hood with the petals at the correct position was okay, but even a few full “backwards” rotations of the lock ring which prevented the hood being screwed down as far as possible started giving me some vignetting.

Even locked down to the right position to start off there’s a slight rotation of the front of the lens to achieve proper focusing (unless you have one of those expensive lenses that have internal focusing), but the movement is fairly minor and didn’t give me any trouble. You probably will have trouble, though, if you screw the hood onto a filter and then try to shoot at 18mm! If using a zoom lens you could cancel any vignette by just selecting a slightly longer focal length at which to shoot.

Apologies for going on, but the take-away is that you shouldn’t have vignette issues using this hood at 18mm on a APS-C format camera. Canon has a 1.6x crop factor which puts you even farther from the 25mm danger zone. If you have a full frame format digital or a 35mm film camera, you would have major issues at 18mm. So, then don’t use any focal length under the 25mm mentioned. Of course, if you are using a zoom lens, you can use it fine at focal lengths greater than 25mm.

I don’t need to penalize this hood by taking away stars as it seems to be well made and does its job very inexpensively.

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.

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

The product meets my needs to serve as an adapter from a Nikon lens to my Canon camera. The only problem has been that I had to do a lot of research to make sure the lens worked. In the product description they are not too specific. Otherwise perfect and received within 12 hours of ordering
