K&F Concept X PRO Square Filter Holder System Kit Review

When it comes to landscape photography and getting the correct exposers nothing is more useful than filters. While neutral density (ND) filters let photographers experiment with long exposures to blur the movement of water or clouds, polarizing filters can be used to regulate reflections, enrich colors, and deepen blue skies.

While it may seem more difficult at first glance, a square filter holder system can be much handier than you think. It lets you switch between different-sized lenses very easily and quickly. Different lenses have different filter threads, meaning if you’re using circular filters they won’t transfer between lenses. This is where Square filter holder systems get more advantages. A square holder allows one set of filters to be shared across multiple lenses with different threads. 

Moreover, instead of screwing in each filter, you can just stack them on top of each other. 

If you’re someone who loves seascapes and long exposures and wants to upgrade your filter set the K&F Concept X PRO Square Filter Holder System Kit could be everything you’re looking for.

Ease of Use

The holder itself has a pretty easy CPL insert mechanism with full protection and the huge size of CPL makes it compatible with some ultra-wide-angle lenses. To mount the system, use the right ring adaptor and put on the holder, then level up and tighten the locking knob. After that, just insert the square filter and align it to cover the entire lens, it’s that easy. Both CPL and nd1000 filters can be put in the filter holder. And thanks to its 14mm focal length, you would find no dark corners while shooting.

The circular polarizer allows you to remove unwanted reflections from the surfaces like glass, water, and even the camera itself. It also helps to enhance color and contrast, especially for the sky and clouds. You can even stack up the circular polarizing filter together with two 100-by-100-square filters to shoot extremely long exposure pictures, even with polarizing effects. Or you can mix different filters for other cool effects to shoot as you wish. You can use up to three different filters at the same time, one of them being the rotating polarizer filter. 

Extending the exposure period using an ND filter results in a light reduction of ND1000 (10 stops), ND64 (6 stops), and ND8 (3 stops) that allows for a slow shutter speed that may be utilized to capture movement in objects like waterfalls and give the water a silky smooth appearance.
