Surprisingly decent quality
Bought this for my fujifilm - i use various recipes for some cool vintage looks but this lens really elevates the pictures. I was a bit worried when I saw the price that it would be too cheap/flimsy etc, but i was pleasantly surprised (its seems silly cheating out on a filter when the lens and camera were cheap). The results have all been really good. Nice glow and ethereal look to everything without being too much. Would recommend for sure.

Add that vintage effect
I really like this filter. I chose the 1:8 as I feel it’s enough on my x100vi. It screws on well and it’s a nice fit, there is no colour cast to my images and the only degrading happening is the one you bought the filter for, that is to reduce clarity and add a nice halo on lighting. I keep this on my camera 100% of the time and it’s cheap enough that should it get damaged, I can justify ordering a new one. Great value for money.

Excellent Filter
This diffusion filter appears to be quite excellent for the money. I can only post a couple of low light indoor test shots (ranging from 400 to 2000 ISO) with normally quite harsh LED lighting to illustrate how this diffusion filter might affect your images, I think the effects are subtle yet rather beautiful :) I look forward to using it a lot more. *4 Stars because nothing is perfect, but this filter is superb.

Brilliant filter
I love this little filter. I use it on my Fujifilm x100s , fits perfectly and it gives a very subtle dreamlike quality but you’re not too far into looking like you’re in a haze. Great quality, I mostly keep this on 100% of the time now for all types of lighting. Doesn’t effect colours and has the bonus advantage of acting like a lens protector.

Very sharp for the price
Pretty damn sharp, even though it's as big as 67mm - including on my 250mm telephoto. Adds a very very subtle glow that I can play around with in photoshop. I like it - much MUCH more noticeable at night with lights like headlights and the such.

Outstanding quality to price
I always find myself favouring k&f products these days but these filters really are worth the money they add so much to the image if you’re after the more “cinematic” look I’d definitely recommend a pro mist filter how it works keeping the contrast but blooming the high lights is like magic 😂 I have used these on my latest short film once I have an upload I’ll add to this review

High quality - great value!
This is great value in my humble, beginner opinion! Introduces a nice bloom effect with a decent light source. Build quality is of high standard and the glass is quality as well! I would say this is a bit more than 10%, but does the job very well either way. Shots taken on my new Fuji X100vi

Great product I started with the 1/4 which seemed a bit light was okay for night time. Then added the 1/2 filter which is good during the day with both. At night the 1/2 is great on its own helps create that vibey dream effect we all want

Buon filtro per fare foto particolari, forse un po' troppo forte, meglio 1/8

This diffusion filter adds a soft, dreamy effect that really enhances video and portrait shots. The cinematic look it delivers is impressive — perfect for vloggers and filmmakers on a budget. I’m glad I didn’t spend hundreds on big brand filters. Highly recommended for anyone wanting professional-looking footage without the high cost.
