52mm Clip-on CPL Phone Camera Lens Filter Kit, Circular Polarizer Polarizing Filter Compatible with iPhone 15 14 13 12 11

This K&F Concept clip-on filter simply fits over your phone's camera lenses and with it being 52mm diameter, it is not going to produce any vignetting - even at 0.5x on my smartphone, you can easily adjust its position so that there is no vignetting.
The 52mm diameter filter size is standard and is the sort of size and any experienced photographer will have filters for so you are not limited to using the circular polarising filter that comes with this.
The only problem with this is that the filter holder/clip is made of plastic including the thread and as such, if you cross the thread when you are screwing a filter into it, you will cause a lot of damage to it. Apart from that, it is very good.

I have used ND grad filters for years on my SLR and DSLR cameras. I love scenery photography as opposed to portrait so always looking to sort out the difference in the light between the horizon etc. I live near the sea les that 300m away and walk along the cliffs regularly and don't take my DSLR with me when walking the dogs but always have my iPhone so any unexpected scenes are normally captured using the iPhone. This ND grad filter will come in useful. It fits over the lenses of my iPhone and helps sort out the difference in the light. Once clipped on it is easy to rotate the bezel to the setting you want using your finger. You have to ensure that you do not go past each of the stops or you will get leakage. SO my advise is to check before shooting that you are at the required stop. The other great thing about this filter is that it unscrews from the clip holder and can be screwed onto my 52mm lenses..Bonus... All in all this is a great little filter that I will carry around with me when out walking the dogs. We have a dog walking bag which has Poo Bags and drinking water etc so it sits in the side pocket of the bag in its case. so it is always there if we get a lovely sunset or something really nice to photograph on the sea or beach.. Get little gadget well worth the money highly recommended... As soon as we get anything really nice I will update this with the images...

K&F’s Clip-on Circular Polarising Filter works just fine with the 3-camera array on my iPhone pro max. It’s easy to mount and remove from the phone when needed. There are rubber pads to protect your phone from the plastic of the clip that holds it in place. It comes with a nice microfibre cloth for cleaning it, inside a plastic clamshell case. (You can store the filter and the cloth in the case.

The filter does a good job with my iPhone; it makes the sky a deeper blue and removes glare from water. It makes the image a little darker; but it isn’t an ND filter for shooting in bright light. I It also made my monitor go completely black when I pointed it at it. The clip makes the filter work with I assume most phones, it does block a bit of your screen in use so you may need to consider where camera controls are when using it. When not using it, I just clipped it to the strap on my backpack.

It didn’t make any appreciable difference to the quality of photos taken with it – outside of the improvement in the look of sky and reflective glare. It also worked shooting through windows removing a lot of the reflections.

I was excited to try this variable ND from K&F Concepts as they make fantastic products

This one comes in a plastic case with a little cleaning wipe (nice touch K&F Concepts).

Taking it out of the case it’s a second to clip onto your phone and then a short time just to make sure you have it right over the camera lens correctly (which is easy, just move it around) so that you don’t get any of the filter edges showing

Once in place you just turn the filter until your chosen effect is reached

For me it’s easy : on a bright sunny day just set your phone video setting to 24fps and shutter speed to 48 or 50 and then put the filter on, turn to max and then just turn it until your video image looks perfect - a two second job and perfect results every time

The fact that the filter has a 52mm thread is amazing as it means I can take it off the clip and put it onto my mirrorless camera lenses too! So I can use this on my phone AND my big camera

Great results, easy peasy to use, and real value for money as you can use it on all your cameras!

Love it

K&F Concept are producing some quality ND filter, especially this variable ND filter which has a 2 to 400 stops. There are clearly marked stops on the filter itself, however these are not hard stops which means you can go past the limits to produce "unwanted" effects like purple hazing and hues. At this point there is some X light leaking, but if you do not go past the marked stops there is no issue. This is primarily made as a clip on filter for mobile phones, but there's nothing to stop you from removing the filter from the clip and putting it on a 52mm lens.

The image quality looks clear and and colour clarity looks good, even towards the edges. However, you'll need to put your phone's camera in manual mode for this be just effective, especially on very bright days.

I would've liked a carry pouch or ND filter lid, however for this price and quality this is good value for money.

This clever clip fits all the phones I have tried, even when the phone is in a case. Once the clip is in place your phone has a 52mm filter ring that will allow you to fit standard 52mm filters. Included in the pack is the good quality K&F concept circular polarising filter. Rotate the filter to see the effect of the polarising filter. Included is a microfibre lens cleaning cloth too. I found that it was easier to carry the filter wrapped in the cloth than use the more bulky plastic box when I was out an about.

Polarising filters are used to increase contrast on bright days, making fluffy white clouds pop in darker blue skies, reduce reflections from water and glass.

This is a very good quality clip on ND filter.
The filter is ND2-400 and you can adjust it by rotating the front ring.
The filter clips on iPhone without any issues and it is just the right size to clip snug around the 3 cameras.
The filter is made to fit the phone based on a phone without case and if you do have a thick case - it doesn't fit well.
I personally have a case that fits snug so it is not that thick , but still the lens filter doesn't clip on very well and I have to take the case off.
The price of this filter is £24.99 , which is not bad for what you get.

Hopefully my review was Helpful for you.

52mm Clip-on ND2-400 Phone Camera Lens Filter, K&F Concept ND Filter Compatible with iPhone 15 14 13 12 11 Smart Phones

This product comes inside a cardboard box; inside the box, you'll find the ND2-400 Phone lens attached to a clamp clip and a wipe (inside of that orange bag) - you can detach this lens and attach it to any compatible 52mm lens (and attach any compatible lens you already own to the holder) which I think is a fantastic design. as off reviewing, this product costs £22.49; this price is very reasonable, especially for a budget photographer.

There's a ring that allows you to change the amount of light that gets in (to make it darker or lighter), and this is good, especially for mobiles, to change the light/darkness in your photos instead of using an editor.

The product is built very well, the glass is high quality and can be used on more than just the holder it comes with (other 52mm camera lenses)

definitely recommend this product

This little filter clip is a fine bit of kit to have when using your phone camera and does a decent job as you can see from my supplied test photo's and if like me you have a few left over 52mm filters from your old film camera you can swap these filters onto the clip as the thread is the same as the old camera lenses and gives your filter collection a new lease of life,

The clip is supplied with a polarizing filter made of high quality glass and simply rotates for the desired effect and you get a really sturdy protective box and a cleaning cloth so what is not to like about this filter clip i highly recommend it.

As a keen photographer, I have polarising filters for other cameras but not for my phone. As they say, the best camera is the one you have with you, and often that is my phone. The camera quality was one reason why I upgraded to an iPhone 14 pro so I was keen to try this with my phone.

In the package, you receive a clip with a 52mm threaded mount, a 52mm CPL filter, a cleaning cloth and a case to keep them in.

I like everything except the clip. I always keep my phone in a case but the clip will not attach satisfactorily to the iPhone 14 pro when it is in a case. It clips on at an awkward angle, the back of the clip obscures important UI elements of the camera app and a large amount of the frame is visible if you use the wide-angle lens.

The polarising filter works perfectly, most notably in removing reflections on water. I wish I had had it when I was trying to photograph wildlife underwater a couple of months ago.

The microfibre cloth is a good lens cloth.

The case is a nice solid box but is quite bulky and confusingly is not quite tall enough to shut properly with the lens clip inside.

The lens clip does fit on the phone better when it is not in a case although the back of it still obscures UI elements on the screen. However, I don't want to walk around with my phone out of its case nor remove it every time I want to use the filter.

I'm now looking for alternative options such as a case with a threaded mount built into it.

At £14.99 I think the price is OK but it is probably better suited to phones with smaller camera bumps.
