I was pleasantly surprised by the quality of this split-diopter prism filter from K&F Concept. It's remarkably easy to install, as it can be freely rotated when attached to the lens, allowing you to experiment with different effects. The construction is precise, and the K9 optical glass is of excellent quality, which is evident in the sharpness and clarity of the images.

This filter provides the ability to create a blurred refraction effect in the foreground, adding depth and layers to images. It's ideal for portrait photography and artistic creation, as it allows the subject of the shot to stand out in a unique way.

Obviously, the ideal would be to have the ability to add levels of blur, but it doesn't seem feasible, at least at a reasonable price. Therefore, we have to play with the possibilities it offers, which are many.

The K&F Concept 77mm Centerfield Split Diopter Filter arrived neatly packed in a professionally printed box bearing the K&F branding.

The Centerfield Split Diopter filter offers a distinctive creative touch by producing a blurry refraction effect around the edges while keeping the center of the subject in focus. It turns ordinary shots into psychedelic and abstract works of art.

It’s perfect for various types of photography, whether you’re capturing landscapes, portraits, or working on artistic projects.

The K9 optical glass used in the filter offers high light transmittance and excellent colour reproduction.
Images come out clear and vibrant, and the special coating helps block stray light, maintaining image quality.

The adjustable frame is a nice feature, allowing you to rotate and tweak the filter to suit different settings and create the desired effect.

Plus, it comes with three microfiber cleaning cloths, which are incredibly handy for keeping the filter spotless. The cloths are vacuum-packed, lint-free, and gentle on the filter, making maintenance a breeze.

Bargain for an unusual addition to your photography equipment.

This is really fun photographic filter. Having a diopter with a slice cut out of the middle lets you make photos where the centre is in focus, but the sides are blurred. Of course you can do something similar using photoshop, but I believe manipulating photos the organic low-tech way has an organic coolness that you just cannot achieve in digital editing.

I like that the filter can rotate freely when it is attached to the lens, but sometimes wish it was available in different “strengths” so I could choose how far out of focus I wish the edges to be. Based on the thickness of the glass this looks to be a #2 diopter. I think I could achieve more useful effects with a #1 diopter, or even a #0.5 one.

Like all K&F gear I own, this one is very precisely built and uses excellent quality glass. They also include a 3 pack of extremely useful little microfibre cloths for lens and filter cleaning and they work well.
