Choosing the Correct Size for Your Lens
Getting the correct size of a polarizing filter is crucial to getting the best result from your photography. The filter size refers to the diameter of the filter, which must fit over the lens’s front element. You would need a different filter size for each lens in your camera bag. But determining the right filter size is a simple matter.
- Check the camera manual – It should describe the filter diameter for the lens that comes with the camera.
- Check the lens cap – You might see something like Ø58 near the center.
- Check the lens barrel – On the inside of the lens barrel, there should be some numbers printed. You’re looking for the number after the Ø symbol.
If you don’t find the size this way, you can use a caliper to measure the front element. Be sure to measure all aspects of the front element and not just the lens’s diameter because some lenses have barrels or protrusions that may affect the filter size.
The table below lists a few of the more typical filter sizes, but you should always check the front element of your lens to be sure:
| Filter Size (mm) | Common Lens Thread Size (mm) |
|---|---|
| 37 | 25, 30, 37 |
| 46 | 43, 46 |
| 52 | 52 |
| 58 | 52, 56, 58, 62 |
| 67 | 67, 72, 77 |
It is essential to get the exact size for your lens to prevent light from leaking in and to block unwanted reflections completely. Using a filter too small for your lens may cause vignetting or dark corners, while a filter that’s too big could cause it to fall off or not seal properly, letting in stray light.
How to Properly Use a Polarizing Filter
Using a polarizing filter can make a huge difference in the quality of your outdoor photography. But knowing how to properly use one is just as important as selecting the right filter. Here are some tips to help you get the most out of your polarizing filter:
- First and foremost, make sure you have the right filter size for your lens. Polarizing filters come in a variety of sizes to fit different lenses, so double-check before you make a purchase.
- Rotate the filter to adjust the amount of polarization. The amount of polarization you want will depend on the scene and what effect you’re trying to achieve. By rotating the filter, you can control the amount of light that enters the lens, which can help you capture richer colors and eliminate glare.
- Keep the sun at a 90-degree angle to your lens. If you’re shooting directly into the sun, you won’t be able to see any effect from the polarizing filter. Instead, position yourself so the sun is to your side, at roughly a 90-degree angle to your lens.
Now that you have a basic understanding of how to use a polarizing filter, let’s dive into some more advanced techniques:
If you’re shooting a landscape scene with a lot of sky, you may notice that the sky appears washed out or featureless in your photos. To bring out the clouds and add more depth to the sky, try using a polarizing filter. By rotating the filter to its maximum polarization, you can darken the sky, making the clouds pop and adding contrast to the scene.
The same goes for bodies of water. If you’re shooting near a lake or river, you may notice reflections or glare on the surface of the water. By using a polarizing filter, you can eliminate this glare and see beneath the surface of the water. This can be especially useful if you’re trying to photograph fish or other creatures underwater.
| When to Use a Polarizing Filter | When Not to Use a Polarizing Filter |
|---|---|
| – To reduce glare on water or other reflective surfaces – To deepen blue skies – To increase color saturation and contrast – To reduce reflections on glass or metal surfaces |
