![]() Square Filters are normally more expensive and you’ll also need a filter holder and adapters. The cost of purchasing a new filter and/or filter system varies drastically depending on the choice of brand, quality and system. However, if you do intend to use a Graduated Filter or perhaps a Polarizer and Neutral Density Filter at the same time, the square filter system is ideal. Adding the filter holder, adapter, pouches and filters seems a little overkill if you only use one Neutral Density Filter at the time. If you never stack filters and don’t intend to use Graduated Neutral Density Filters, the screw-in option is the better alternative. It took me years to find the system that’s perfect for me but my needs also changed during that period.Ī Square Filter System was used in order to have both a circular polarizer and 10 Stop ND Filter at the same time. This highly depends on your preferences and budget. I’ll be honest with you right away: there’s no such thing as the perfect system for everyone. What’s the best system for Neutral Density Filters? I recommend double-checking what’s included so that you’re sure you’ve got the correct adapter size for your lenses. Most filter kits include adapters of different sizes but this might vary between brands. For example, in the NiSi V6 Pro system, you can place a Circular Polarizer inside the filter holder but for other brands, you might need an additional adapter. Keep in mind that there are big differences between brands both when it comes to the quality of filters and holders, and their design. – Flexibility of rotating and adjusting filter positions Though the higher quality options tend to be stronger, it’s also known that the square filters are slightly more fragile. Now, this system is bulkier than the screw-in filters and you’ll notice a significant difference in both size and weight. This is especially important when using Graduated Neutral Density Filters. You’ll also find that this system is more flexible in use as you can rotate the filter holder and slide filters up and down in their slots in order to better align with the specific scene you’re photographing. Certain ultra-wide-angle lenses might get a slight vignette with some brands but it remains the same if you’re using one or three filters. In other words, it’s possible to use several filters at the same time without seeing any unwanted vignetting. The main advantage of using a square filter system is that it holds several slots where filters can be placed. A filter holder is then clipped onto the adapter and it’s in here that you insert the filters. Unlike the previous system where the filter is screwed directly onto the lens, an adapter is the first piece mounted with this square version. The square filter system is slightly more advanced than the screw-in and requires a few extra pieces of equipment in order to be properly mounted to the camera. Alternatively, you can purchase adapters but make sure that the filter is big enough to fit the lens with the widest diameter. Keep in mind that the filters aren’t expandable which means you might need to purchase different sizes for different lenses. – Possibility of getting ‘stuck’ on the lens – Graduated filters are less flexible in use – Vignetting issues when stacking multiple filters ![]() It’s not too difficult to remove the vignette in a photo editor such as Adobe Lightroom or Photoshop but, be aware, the more filters you use, the harder it gets! Advantages of using screw-in filters: This type of filters is quite common and is typically the only option you’ll find in a general electronic store. The first alternative is the round Screw-In filters that are, as the name indicates, screwed on to the front element of a lens. Let’s take a closer look at each: Alternative #1: Screw-In Filters To begin with, it’s important to understand that there are two main types of filter systems: Screw-In Filters and Square Filters. It can be rather confusing to know what type of Neutral Density Filter to purchase if you haven’t looked much into them yet there’s an abundance of brands, systems, setups and even types of filters. The different types of Neutral Density Filters Exactly how long the shutter speed can be, depends on the filter you’re using it could be anywhere from a second to several minutes. Since the filter reduces the amount of light entering the camera, you’re forced to use a longer shutter speed. The solution is a Neutral Density Filter. If it’s still bright outside, this little workaround won’t lengthen the exposure time enough to create a nice blur anyways. Using a narrow aperture, such as f/22, lets you slow down the shutter speed a little but the consequence is a loss of image quality.
