Choosing Camera Lens Filters & How To Avoid Costly Repeat Purchases When Buying A New DSLR Lens

When you first get your brand new, expensive and sophisticated DSLR camera, you may be forgiven for thinking that’s all you really need to take good photos… and, for a time, you’re content to explore the myriad of features and settings that festoon the outer body of the camera, as well as those hidden among the many pages of your camera’s bottomless pit of menus and sub menus.

This was my initial thinking, when I chose to “get into photography”, as a hobby. However, it wasn’t long after purchasing the camera and practicing using it on an almost daily basis, that I found myself wanting that bit more.

One of the reasons for purchasing the camera was because I’d ruined my eyesight over a period of a few years, by spending too much time working in front of a computer and not doing much else, as I tried to build a business online. I chose photography as a way to, quite literally, focus and re-train my visual system to start looking further afield, rather than just a few short feet in front of me (the approximate distance from my chair to the glare of my computer’s monitor), to try and “exercise” my eyesight back to a better state of health. For this reason, I was reluctant to try and improve my photos by shooting in the highly recommended “RAW” format and then spending time in front of a computer to edit the photos. Because of this, I recorded all my photos in JPEG format (letting the camera compress the images down into photos that can be instantly shared or printed) and chose to explore using filters as a way to enhance image quality.

Choosing Filters For Your DSLR

Before you purchase any filter for your DSLR, you first need to know the diameter of your lens, since the filter or a filter adapter will typically need to be screwed over the lens. The quickest way to find the diameter for your camera’s lenses is to take off the lens cap and look on the back of it – this is usually where the size, in millimeters (mm) is printed or engraved. For example, the camera I originally bought my filters for was a Panasonic FZ1000; it has a lens diameter of 62mm and so, on the back of its lens cap I found 62mm engraved into the plastic. With this information, I was able to search for all sorts of filters on Amazon, simply by typing in their name (e.g. Circular Polarizer) and adding 62mm into the search bar.

These are the four filters I accumulated over time, which might interest you:

1. Circular Polarizing Filter… A polarizing filter helps to cut through haze and glare from the rays of the sun; they’re a very useful filter for Landscape photography. You can even use a polarizer to see through the surface of water, often revealing what’s hidden blow. You can also use these filters to remove glare from the sun’s reflections in water, and shiny surfaces, like leaves. Polarizers come in square or circular format, but it’s the latter – the Circular Polarizer – that is most often recommended, by photography experts, for DSLRs. So, that’s what I chose and the brand I purchased was the Marumi Exus Circular Polarizer – I’d had no experience of filters, so relied on a single, glowing review on Amazon, and I’m very pleased camera lens for sale with the results. To use a Circular Polarizer, once screwed onto your camera’s lens, you’re able to rotate the filter, in either direction (just be careful not to unscrew the filter in the process!). Circular Polarizers are said to be effective when you’re standing at about 90 degrees to the rays of the sun (so, with you facing forwards, if the sun is either to the left or right of you, as you look through your electronic viewfinder or on your DSLR’s LCD screen, you’re likely to be able to see the filter working as your rotate it on your lens). When it comes to Landscape photography, colors in your image can appear richer and more vivid, when using a Polarizing filter.

2. Graduated Neutral Density Filter Kit… When you look at scenes of contrasting light and shadow (such as out in nature), your own visual system is so sophisticated that, in one glance, you can see detail in both the sky and in shadier parts on the ground. However, at present, even the most sophisticated digital imaging sensor in modern DSLRs has difficult recording the details in the sky AND the details on the ground, or in less well lit areas of your scene, at the same time. You may have noticed this when pointing your camera lens at the sky and using the autofocus system – with the correct camera settings, the sky will appear nicely exposed (ready for you to take the photo), but the ground elements will tend to be dark (and maybe too dark for you to see the detail in the resulting photos). Conversely, if you focus on the ground elements, the detail in the sky will be washed-out and lost to the brightness – you may be lucky with some wispy detail, but it’s nothing compared to how much detail you were able to get when focusing your camera directly on the sky, albeit at the expense of the ground detail. A solution for this is to use what is called a Graduated Neutral Density Filter, with square “ND Grad” filter kits being the preferable option. With the ND Grad Filter kit, such as the Cokin P Series (H250A), which I purchased for my Panasonic FZ1000, you will need a Ring Adapter, which screws directly onto the lens (this is usually a separate purchase from the rest of the ND Grad filter kit). On top of this, you slot the Filter Holder, into which you slot up to three different, rectangular pieces of Perspex, which are the filters. At one end, the filter is clear; at the other, it’s somewhat darkened; and, in between, they fade from darker to lighter, or vice versa (depending on how you look at them). If you place the dark
