Sigma Camera Lens Filter Size Chart

Filter size finder: Which filter size does your Sigma lens take?

What filter size does your Sigma lens take?

Start typing the lens (focal length is enough). The filter thread, hood, and where to buy appear below.

Find

Here are the lens diameters and corresponding filter sizes for common Sigma lenses. If you’re after a replacement or spare lens hood, I also have a Sigma lens hood compatibility chart.

I’m focusing here on lenses that accept a screw-in filter on the front. Some lenses, such as very wide-angle or fisheye lenses, don’t have a filter thread on the front and can’t accept this style of filter. And some very long telephoto lenses use a system of drop-in filters at the rear of the lens.

Some focal lengths have multiple lenses, so it’s important to match the other parts of the name. It’s common for lens manufacturers to produce multiple lenses at specific focal lengths, and they don’t necessarily have the same lens diameter and filter size. And Sigma often has the same focal lengths in different series (eg. Contemporary and Sports), and you can’t assume they’ll use the same size filters (they often don’t).

This is an ongoing list. I’m starting with Sigma’s current range and adding older lenses to it as the opportunity arises. Please feel free to send through any additions, requests, or corrections.

If you don’t see your lens listed here and want to find out the filter size, it’s often marked on the lens itself. For a more detailed guide, see my post on finding the lens diameter.

A quick way to filter down from this long list is to use the chart’s search bar to narrow it down by focal length (eg, type in “70-200”).

Sigma lens jargon

Like all camera and lens manufacturers, Sigma adds their own jargon to their lenses and related technology. Here’s how to decode some of the main terms you might come across. (I have a more comprehensive guide to Sigma lens codes separately).

• DG: Designed for digital. But that’s not quite all there is to it. Basically, it means that it works on full-frame cameras. DG lenses will work on full-frame, APS-C, and film cameras. DC lenses will only work on APS-C cropped sensors. Sigma has its DN lenses, which are for mirrorless micro4/3 cameras.
• DC: Sigma uses DC for lenses designed specifically for cameras with APS-C sized sensors.
• HSM: Hyper Sonic Motor. This refers to the autofocus mechanism and trying to imply that it’s fast and quiet. Nikon’s version is called Silent Wave Motor.

Sigma’s current range is divided into three categories, or lines. The distinctions are often more useful in marketing than in practice, but when there’s overlap in the focal lengths, the Art and Sports lenses tend to be more expensive and have higher specs and performance, with the Contemporary series aiming more for the enthusiast end of the market.

• C / Contemporary: Sigma’s “Contemporary” series. The Contemporary series lenses are more designed for general everyday photography, with their own combination of price, optical performance, speed, portability, and versatility. Or, as Sigma marketing puts it: “Engineered for today’s photographer who wants to do it all, our Contemporary line combines superior optical performance and compactness for high-performance lenses that cover a wide range of needs.”
• A / Art: The Art series leans more heavily on optical performance and is less worried about things like focusing speed. Or, as Sigma puts it: “Engineered for those who see photography as a critical expression of self, our Art line offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision.”
• S / Sports: While the Sports series aims for, well, sports, but also nature and wildlife photography. So they tend to have a combination of high optical performance and fast responsiveness. Or, in Sigma’s words: “Engineered for dynamic capture and split-second timing, our Sports line delivers sophisticated optical performance to get you closer to those powerful action shots you’re after.”

I-Series. There is another series known as the I-Series. This is a collection of compact prime lenses designed exclusively for mirrorless cameras. They have all-metal bodies, manual aperture control, and magnetic lens caps (most of them, anyway).

Step-up & step-down rings (the money-saving trick)

You don’t necessarily need to buy a separate filter for every single diameter listed above. In fact, a common money-saving strategy used by pros is to buy filters for their largest lens and adapt them to the smaller ones. (NB: This only makes sense for creative filters like polarizers and ND filters, not for protection filters (UV/Haze, etc).)

For example, high-quality filters are expensive. A pro-grade Circular Polarizer might cost $150. Rather than buying a 52mm version, a 62mm version, and a 77mm version (costing you $450 total), you can simply buy the 77mm filter and use inexpensive rings to fit it onto the smaller lenses.

These rings come in two varieties:

• Step-Up Rings (Recommended): These allow you to attach a larger filter to a smaller lens thread.
  • Example: If you have a lens with a 52mm thread but want to use your 77mm filter, you would use a 52-77mm Step-Up Ring.
  • Why use them: This is the safest method. Because the filter glass is physically larger than the lens requires, there is zero risk of vignetting (dark corners).
• Step-Down Rings (Use Caution): These allow you to attach a smaller filter to a larger lens thread.
  • Example: If you have a lens with a 77mm thread and try to attach an old 67mm filter using a 77-67mm Step-Down Ring.
  • Why use them: Generally, you shouldn’t. Because the filter is smaller than the front of the lens, you will likely see the black edges of the filter in your image (vignetting), especially on wide-angle lenses. An exception might be if you are switching a full-frame camera into APS-C mode.

I have more information on how to use step-up and step-down filter adapters separately, but the general rule of thumb is: Buy Big, Step Up. It is the most economical way to build a versatile filter kit.
