77mm Gold Streak Effect Lens Filter (2mm) Anamorphic Optical Glass Light Flare Effect Filter for Camera Lens Nano-Xcel Series

I was unaware that there was a lens capable of producing this type of effect. It fits perfectly on my Sony 82mm lens, and I can still use the lens cover without having to remove the effect lens.

The effect can be adjusted because the glass is loose enough to move (but will remain in place).

This lens is ideal for taking pictures of cars (with effects on lights). However, it is not very useful for outdoor photography during the day. It is intended for lighting effects rather than sunlight or outdoor use.

This gold streak filter is perfectly packaged.

The filter itself feels very premium, and spins onto my lens effortlessly.

The gold streak provided by the filter on light sources will be very useful when trying to achieve a certain effect on some of my photos.

Great filter!

This product from K&F CONCEPT IS A 52 MM GOLD streak anamorphic lens flare look alike. This acts as a substitute for actual anamorphic light distortion. But does not recreate the wide angled low fisheye lens distortion of an actual lens of this type.

The whole concept is simple enough to understand. Two peaces of pristine glass with light refraction coatings. With gold filaments sandwiched between them. This is how the look of the flares is achieved.
When the camera focuses on distant objects the filament is blurred and all highlights passing in front of them will be refracted. Traditionally there were only two types of these on the market. A warm golden coloured one and a blue filament one. Now in the new market there are many different types of colours to choose from.

The caveats:
The lens flares can get overwhelming when filming at night time. Especially with cars and light posts it might be a bit distracting depending on the kind of shot you are looking for. In some cases the light streaks will look small and broken as shown on the picture above. This is do in part to how far away you are from you're subject and the depth of field used.

Final thoughts: 5 out of 5
This is a fantastic alternative to adding lens flares in post production, saving you time and money. Although, not as convincing as the real thing. It gets the job done and can really make you're productions stand out from the pack. Especially if you are going for a futuristic or sci-fi look. This will enhance the visual tone of certain shots. Bringing a bolder look to you're cinematography. 5 out of 5 for me. This is going to stay in my gig bag for sure.

Occorre per restituire un effetto cinematico anamorfico alle lenti che usate.
Nel caso particolare, restituisce delle strisce dorate sottili alle luci dirette nell’obbiettivo, come lampioni, lampade varie, riflessi etc.
È particolarmente indicato per la fotografia notturna a iso basse e treppiede.

I have quite a few K & F products, filters mainly, in my collection and this latest one is of the same high standard engineering and optically-wise as the others. It comes in a cardboard box with the actual filter inside its own plastic screw-on protective/storage case. I have the 77mm size - it fits the filter thread on my Canon 14-40mm lens really smoothly as I expected as their engineering is first class as I have found with their other products. In use I have it mounted on my 5D 11 plus tripod and so far my efforts are looking okayish - it’s really down to me as I am still experimenting and will add images on here when I am happy with end result otherwise it degrades the product, which is first class, to my mind.

I really like the effect this filter gives. I've tried it on a couple lights inside the house and a local street light and it gives the gold streak effect nicely. I'm eager to try it out on some street photography the next time there's a fair or festival with a lot of lights on rides and attractions. I think it'll present a cool look to the photos.

I've recently picked up a variety of different K&F filters (ND, mist, etc) and have been impressed with them. They offer a great value compared to some other brands, and the quality is nearly indistinguishable. With this filter, it's aiming to give you the type of flares that you expect to see from an anamorphic lens. While those lenses have a more subtle flare, this filter products far more streaks under certain lighting conditions. The fact that you can get that look on whatever lens is pretty sweet though, and for that I'd recommend it if you like the look.

It really enhances an image, if you're looking for that little pop to tell a story , this is the lens filter! You can spin it and change the rotation of the flair. Its great!!

As you'd expect from a K&F product it works like you'd expect. Does a nice job of creating those light streak from most light sources. You can rotate the lens to angle each light streak however you want for your project. Haven't taken any photos with it just yet but I can tell this will serve me well. Was surprised the carrying case was abit bigger than I thought.

I am new to K&F filters but I have acquired 3 in the last month and have found them all to be of very high quality. This K&F Concept 72mm Gold Streak Effect Lens Filter is no exception.
The lens is well-made and fits and functions well.
The effect of the lens is very good.
Like all special effect lenses, it should be used sparingly and after much practice.
