The K&F White Soft Diffusion Filter is roughly like stretching white nylon stocking over the lens. It gives white highlights a glow, softens the image and reduces contrast.

Attached are two shots I took with my Sony A7s & Sony 24-105 Lens. The lens length for the photo is at 105mm. I am the beautiful model. Usually these filters are rated for intensity 1/8, 1/2, full, and so on. I am guessing this one is full. To me, it is a dramatic effect. Would lend a black and white portrait a nostalgic style.

As with all K&F filters, the quality appears to be excellent. This filter has large knurls on the edges making it easy to mount to the camera.

It is a good quality filter, great glass coatings and all, but I was dissapointed that it did not do better, It was more my fault choosing this one. They come in strengths and I made a poor choice. I also learned later from trying other peoples filters, that I really should have gotten a Black Mist filter instead, for the effec I seek.

First time using this one of these filters let me say I'm impressed with this makes the picture look better.

I use this filter for one of my Tamron zoom lenses. I like the subtle softening effect for portraits, especially in an outdoor setting, where there's a lot of contrast. I don't recommend it too much outside of portraits or nature photography, since that is when I think the softening effects looks best. The lens itself is really good quality, and screws in easy. You can even screw it in and layer it with other k&f lenses

The effect is subtle in most situations, but it does help cut down on the harsh digital sharpness of a modern camera. I've been using it mostly for portraits to soften skin a tad, but I really want to try this on lights at night, like some other reviews have mentioned. Nicely made filter though, with smooth threads and clean optics. K&F makes some really nice stuff!

I'm a life-long photographer (DSLRs for 18 years) but I haven't shot more than a handful of photos with a diffuser before... mostly because I don't do a lot of portraiture, and because there really was a big difference between the economical diffusers and the expensive ones, the cheaper ones not really looking that professional.

Anyway, I decided to try this one. I'd love to write you a comprehensive, scientific, analytical review, but this filter has left me a bit baffled... but perhaps I'm just confused.

I've thought that diffuser filters are good for a few things:
1. Portraits - softening the skin
2. Making high-contrast images a bit "dreamy"
3. And maybe for giving a more dramatic effect for points of light in a low-light shot

The weird thing is, when I shot nearly identical shots with my Canon full-frame with and without the filter, I was actually getting sharper details and richer colors USING the diffuser! This of course, is not expected. Now, I was shooting hand-held, but I can't believe that in every case, I shot more steady when the filter was on than I did when it was off. But whatever it was, my test shots came out sharper and overall better WITH the filter. But to be honest, unless you peek at the pixel level, there was no noticeable difference when looking at the full image.

I suspect it comes down to focal range and that a diffuser works better with close-up shots... yet my static shots of highly-detailed subjects hardly showed a difference at all.

However... in the scenario where a diffuser is most likely to be desirable - portraits with natural skin... I DID see a difference... subtle, but definitely a softer touch to textured skin.

So... I can recommend this for portrait shots... and I can even recommend it for landscape shots - I'm just not sure WHY they came out slightly better with the filter!

I like this filter, that being said I have to say that a lot of people who buy this or other filters have the wrong idea about what they do or can do for their photography. I say that because professional reviews which show what these filters do as well as the Amazon reviews pretty much indicate that there are times when you really see very little difference between filter/no filter shots. Basically, a White Mist filter tends to give a shot a brights dreamier look by diffusing (expanding the light/light area), but you WILL NOT see it in every photo and every situation and in some situations, you will not see any appreciable difference at all.

So, while I recommend the filter, I would also recommend that anyone looking to buy one take a long look into when, where, and why you want to use a White mist filter and what it can do for you. I say that because I think too many people bring in unrealistic expectations into what their photographic gear can do for them as opposed to what proper composition and control of the lighting should do for them instead (I include myself in that observation about unrealistic expectations because I am just beginning to use more filters and at first I thought that using filters would make a huge difference most pf the time, when really most of the photos I take it wouldn't matter if I had a filter or not). What I would recommend is that if you haven't already, look into what the filters can and cannot do and perhaps look for a good book/tutorial on lighting and filters (although the cost of the filters is not much, buying a variety of them to fit all of your lenses adds up when often you are not really ready for them yet).

This filter provides a very light touch to photos. I believe K&F have it right in that it dials back contrast somewhat. The photo with the filter missing in its box is taken with the filter on the lens, and the other is without.

I forgot to take the filter off my lens when I next shot some other product photos and I immediately thought I should retake them. But looking at them I decided they looked pretty good in spite of the fact that this filter is for portraits. With just a hint of a softer appearance, they were still quite satisfactory and I liked them.

I think this is a pretty nice filter with a modest effect, and that's for the better. The construction is good and it's not very expensive. This would be a pleasant addition to some photographers' filter collection. Recommended.

Mist filters can be somewhat duplicated in post-processing, but not perfectly. If you are looking to get that soft look in-camera, you'll need them. With that said, it is just another thing I have to take with me, and so I probably won't be using it all that much. As for the filter itself, K&F always makes some decent gear, and these filters are no exception. They are well-made and the effect is subtle and not overpowering.
