FILTERS, THE PHOTOGRAPHY SEASONING
In this guide, I will introduce a long list of photography lens filters that I think every photographer should have, and make recommendations of the cheap fantastic that I have used before.
Add some spice to your photography without burning a hole in the wallet. Why not?
But as I wrote this guide somewhat “for the newbies”, I have included some very basic things about lens filters. So feel free to skip through those sections if you are already an advanced photo ninja.
Disclaimer: This guide includes some extremely Photoshopped example photos to illustrate the effects of the filters. It is definitely not because I am too lazy to go out and shoot with all the filters. 😆

ALL ABOUT FILTERS
What the heck are lens filters and what do they do? The easiest way for me to explain lens filters is to ask a question – Why do people wear glasses? Sunglasses? Tinted lens? For the very obvious reason to correct their vision, or maybe the sun is just way too bright.
The same goes for lens filters, which are lens attachments with all sorts of effects. That can be a simple dark filter to block out some light, UV filter to block out UV lights, funky filters that adds a color cast, or filters that create light streaks.
WHY USE PHYSICAL LENS FILTERS?
I know, there is Photoshop and Lightroom these days. All you need is press a single button to apply a filter. So why buy a physical filter? Photoshop can do all kinds of magic, right?
As much as I love Photoshop, you need to understand that there is a limit with digital applications. For example, there was once when I was shooting landscape, and a “Professional Photographer” came along. The question he shot at me, was why am I still using a physical filter. Applying a filter in Lightroom has the “same effect”, and it is easier, right?
I pretty much wanted to slap that guy in the face.
Well you see, I had something else in mind. I needed a long exposure of 5 seconds to get that “cloud rush effect”. It was broad daylight, and not even shooting at f/22 will get me to that kind of shutter speed. Solution – use a piece of dark glass called ND filter to limit the amount of light, so I can shoot at 5 seconds without over-exposing.
There you go, and it is not just ND filters. Good luck trying to get infra-red in Photoshop. Physical filters are not useless.
THE DIFFERENT SHAPES OF FILTERS
Filters typically come in different sizes, and 3 shapes – circular, square and rectangular. They all work, but what’s the difference? Well, square and rectangular pieces are generally larger, and they fit onto more lenses without any issues.
CIRCULAR SCREW-ON FILTERS
The common Joe lens filters are circular in shape, and you screw them onto the front of your lens. But before you buy a circular filter, do check:
- If your lens has a front screw thread. A few odd lenses in this world do not have screw threads for you to attach a lens filter.
- Take note of the diameter of your lens – which is generally marked on the front side of your lens.
- You do not want to buy a filter that is smaller than the diameter of your lens!
Generally, you will want to get a filter that has the same diameter as your lens, or even larger where possible. Personally, I will usually get 77mm or 82mm filters, which should fit nicely onto most lenses. Think of it this way – A 52mm filter will not fit a 82mm lens, but a 82mm filter will fit almost every lens out there with a step-up ring.
Horray and yes, you can attach multiple filters to a lens by screwing them on top of each other. This is what we call “filter stacking”. But avoid stacking too many filters, as that will cause vignetting and a loss in optical quality. Also, note that not all lenses can be “stacked”. Circular polarizers, for example, don’t have front screw threads.
SQUARE OR RECTANGULAR FILTERS
These are huge pieces of filters, which is probably going to cost more than the circular ones. But given their size, you don’t have to worry about it not fitting onto the larger lens. Square and rectangle filters generally come with an attachment ring and filter holder.
The attachment ring is screwed onto the lens, the filter holder is attached to the attachment ring, then the filters are slot into the holder… or you can totally just handhold the filter in front of the lens. Doh.
These are the pure basic filters that I think every photographer should have. These filters will come in very handy no matter what you are trying to shoot.
The clear filter is a piece of… clear glass or plastic, and it does absolutely nothing optically. Yep, it’s the only purpose is to protect the lens. Scratch the cheap filter, not the lens.
Not many photographers actually like to use clear filters, since they do nothing. A better alternative will be the Ultra-Violet filter.
Just get a cheap one from eBay if you want – [Link]. Note that most Chinese sellers are selling cheap $2 clear filters as “UV filters”. But in fact, they do not have any coating to block out UV. Just know that you are buying a piece of clear plastic with $2.
Filters out unwanted UV lights that causes blue tints, and protects the lens. This is a common filter and better choice than the clear filter.
Some people think that UV filters have no effect what-so-ever. But a good UV filter does remove that bluish tint from extreme UV lights.
CIRCULAR POLARIZER (CPL)
Makes skies bluer, reduces reflections, good CPL filters will boost the contrast as well.
CPL filters normally do not have front filter threads, and they have a rather thick profile. So forget about filter stacking with CPL.
FOR THE LANDSCAPE PHOTOGRAPHERS
If you are into landscape photography as I am, you are going to need a different set of filters. These are the filters that have stuck with me since I began my landscape journey.
NEUTRAL DENSITY FILTER (ND)
Neutral density filters are the fancy way of saying “sunglasses”. It is a piece of dark glass that blocks out the light.
There are a few types of ND filters. The “regular” one being an entire dark piece, and graduated ND filters being half dark and half clear. The reason for using graduated ND filters is such that you can cover only the sky (or horizon), to bring back a balanced photo.
Also, there are different “grades” of ND filters – 1 stops ND, 2 stops ND, 3 stops ND, 10 stops ND, etc… That basically means “the more stops, the darker it is”.
There are many brands out there offering ND filters, even circular ones. My advice is to go for the rectangular ones – you will not regret getting those. Just spend a little money on a set of [Zomei ND filters], if you want quality, get a slightly more expensive [Haida].
INFRA-RED FILTER (IR)
Blocks out visible lights, allowing only IR lights into the camera.
IR filters are very difficult to use… avoid this especially if you are just starting out with photography. Once you slap the IR filter on, all you can see is a sea of red to the naked eye. IR photos also need a lot of editing, but well worth the effort as it produces beautiful surreal photos.
THE MACRO WORLD
I am not a fan of macro, and it is just one of those things I cannot get right somehow. But if macro is your thing, these are the things you might want to check out.
I am not a fan of macro, but neither am I a fan of macro filters. These are basically cheap magnifying glasses. If you are into macro, go get something more… professional.
There are many cheap unbranded magnifying glasses, but get one from [Andoer], these are decent.
MACRO EXTENSION TUBES
Not a filter and I don’t do much macro photography. So don’t burn me. But I do think extension tubes are better as they don’t have glass elements – they modify the focal plane, and does not disturb the optical quality.
There are plenty of options when it comes to extension tubes. I have not played with them enough, but know that some of the cheaper options can mess up the auto-focus.
Try getting a [Meike]. They make decently good extension tubes.
SPICING THINGS UP
Now for a section on filters that are… rather funky. These are effects filters that you may find interesting, or otherwise, totally useless. Well, I am sure there are many places where you can put these into good use.
Adds funky color tints to your photo.
As a newbie, I loved colored filters… or just cheap pieces of colored plastics. Which then, I realized I can just change colors in Photoshop. So why? Well, these color filters are still useful if you want to add a little bit of orange warmth back to a grey sky, or maybe add some red to a dramatic portrait.
There are plenty of cheap unbranded ones on eBay – and they are good enough.
Starburst effect. Adds bling to your shots.
The “starburst” effect is a great addition for those Christmas and idol type portraits.
Well, the generic ones will do.
Create shapes from bokeh balls. Next level bokeh.
Ain’t my thing… but it’s heck a lot of fun playing with the bokeh balls.
You can actually cut out patterns on paper to make bokeh filters. But if you are lazy, just get a pack of them on eBay.
For the last section, I shall introduce the simplest tools a photographer can get. If you use filters, there will definitely be times where things get stuck and what not. So having just a few simple things around will make your life a lot easier.
STEP-UP / STEP-DOWN RINGS
The filter is too big to fit on the lens? Use a step-up ring.
There is no rocket science behind this… just use these adapters to fit the filter onto a different sized lens.
There are plenty of cheap unbranded ones on eBay, but try to go for the metal ones. They are much more rugged.
Removes stuck filters.
There are quite a few variations for the filter wrench. I just got a simple 2 piece plastic, and they work like a charm.
An unbranded cheap one on eBay is good enough.
WHICH IS THE FAIREST OF THEM ALL?
Here we come to the end of this very long list of filters. If you are a beginner photographer, which ones should you get first? The UV filter.
One for every lens that you have, and leave it on permanently. Seriously. Also as a landscape/portrait photographer, I have to mention that circular polarizers and ND filters are my most used filters.
But for you, it’s really up to your personal interest. Whichever one you get, have fun, and the filter will serve you well.
