Thank you for taking the time to read my review.

For those who don't feel like reading through the whole thing, I'll include a pros and cons at the end.

Today I'd like to share my personal opinion on the "Linear Mirage Pentaprism Filter" from K and F Concept, which I was able to test as part of the Vine program. This doesn't influence my review in any way. I hope this can help you decide for or against the product.

The "Linear Mirage Pentaprism Filter" from K and F Concept is a surprise when you first take it out of the box. The storage box is twice as thick as other "normal" filters. When you open the plastic box, you'll understand why.

The filter is made of approximately 1.5 cm thick glass on one side and tapers from the center to the edge to approximately 0.8 cm. It weighs 76 grams. The thinner section (from halfway through the filter) is divided into four sections with varying degrees of inclination.

The filter screws easily onto the lens thread. It doesn't jam, and unscrewing it is also easy.

When taking photos with the filter, the actual subject is reflected four times from the side. You can rotate the filter like a polarizing filter to influence the direction of the reflections. The effect is very nice, and I can't detect any distortion or noticeable loss of image quality in the images.

This filter is certainly not a filter you'll use every day for your photos. However, if you want to take creative photos, this is a high-quality solution without having to use Photoshop or other image editing programs after taking the shot. Here, you can see the effect directly during the shot, and you don't have to spend a lot of time isolating the subject.

I find this filter particularly useful for colorful subjects or subjects with colored light. I would recommend it, or other similar filters.

Pros:
+ High-quality workmanship
+ Great effect
+ Solid glass filter
+ Easy-to-use thread
+ Three individually sealed microfiber cloths included

Cons:
Price for a creative filter (but justified given the quality of workmanship)

Thank you for taking the time to read my review. I hope this was helpful in your decision-making.
