○ The brand K&F Concept sells a lot of camera-related products with low prices, good quality, and cool design, and it's a brand I trust, and I love several products, and I don't often lose money. ○ Case The case thickness is 43 mm, and filters up to about 20 mm can be stored and carried at the same time as this clip. ○ The size of the hand strap can be adjusted to 0-240 mm (diameter 0-76 mm when turned into a ring), and the strap cord has moderate slip resistance, which helps hold the smartphone in some cases. ○ Clip Since the place where it is clamped to a smartphone extends up to 11 mm, it can be attached to a smartphone in a regular case without any problems. The photo also shows a 214g Kenko AC Closeup Lense No17 attached, but even with such a heavyweight close-up lens, I was able to shoot stably by aligning the optical axis. I can recommend it as a very good product.

As shown in the picture, the clip part is moved up and down to pinch the smartphone. Unlike those that are sandwiched diagonally like clothespins, the advantage of this type is that the tip does not come into contact with the lens ▼ The scissors are short at about 30 mm, and it is also good that the range to hide the screen is narrow. However, compared to long ones, the sense of stability is poor. Also, I want to be careful not to let the lens part float ▼ this is a K&F CONCEPT product that I personally trust very much. This one didn't disappoint either.

This is an adapter for using a camera filter with a smartphone. This is a useful idea product. After using it, the filter is very smooth to put on and take off, and I have the impression that the product workmanship accuracy is high. The weight is reasonable, and it's not very light. However, I wonder if the fixing force is slightly weak. If it's strong, the smartphone is likely to get scratched, so it can't be helped. If it's a smartphone with a TPE case, it's securely fixed and doesn't shake. When I try shooting using the filter, I can check (reflect) the function of the filter properly. I think it's a very easy to use product.

Quality excellent, nice price.

It is a filter that can be easily attached to a smartphone camera. The clip type makes it easy to put on. It's nice to be able to take photos and videos and add changes.

[Excellent unique lock mechanism] The biggest stress when shooting filters with a smartphone was “misaligned clips” and “trouble attaching”, but this product solved that perfectly. It is not an open leg like a typical clothespin, but it has a structure where the arms rise and fall in parallel. Therefore, force is always applied perpendicular to the lens surface of the smartphone, and it is wonderful that the filter adheres perfectly without floating. The unique push lock button is also excellent, and positioning can be performed simply by pressing and sliding, and when you release your finger, it is firmly fixed. [Use the equipment you have on hand] It's more convenient than you can imagine that the 58mm diameter filter for single-lens reflex cameras that you had left over can be used directly on your smartphone. There is no need to go out of the way to buy a new magnetic filter etc. for smartphones, etc., and the range of shooting expanded all at once, such as turning off reflections on the surface of the water with a PL filter and cutting the slow shutter with an ND filter. The screw cutting part is made of metal, so there is no need to worry about it being scraped even if you put it on and take it off frequently, which is also a good impression. [Points of interest] The depth of the clip may be slightly severe compared to the large camera units (overhangs) seen in high-end smartphones these days. There was no problem with my model, but if you wear a thick shockproof case, etc., there is a possibility that the pinch will be shallow, so be careful. Also, although the aperture of 58mm is large enough, vignetting may appear at the four corners when using an ultra-wide-angle lens, so in that case it is an operation to avoid it by zooming slightly. [Overall Review] This is a shooting aid tool with a very thoughtful design that sets it apart from a simple plastic clip. It's lightweight at only 19g, and comes with a strap just in case, so it's not a burden even if you keep it hidden in your luggage during a shooting trip. If you have an SLR or mirrorless camera and know the fun of filter work, you should be extremely satisfied as an accessory you can get in this price range.
