Here are the lens diameters and corresponding filter sizes for common Sigma lenses.
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.
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 down by focal length (eg. type in “70-200”).

Hi, I have a 20mm Sigma Art 1:1.4 lens which I mainly use for astro. I would like to fit a u.v. filter on for protection purposes. I have contacted Sigma UK who tell me that they do not have a filter or a filter holder that will fit. Can you advise please?
David says
Assuming it’s this model (and it should be), it’s not compatible with screw-in filters because the front element isn’t flat but bulges out. And it doesn’t appear to be designed with a rear drop-in filter. Adding a plate filter with a filter holder to the front doesn’t make much sense in this case because it wouldn’t help with protection, and it would be hard to do in such a way as to avoid vignetting from the very wide field of view. So it looks like the best bet for this lens is religiously using the lens cap for protection (the metal version is model #LC907-02; the plastic version is #LC907-01; or you can use a flexible neoprene or rubber one that stretches over the end).

Thanks very much David for the rapid response.

Hi, I have a sigma 150 mm – 600 mm f 5 -6.3 hsm os telephoto lens which has a 86 mm filter thread ,screw – in type filter . Using reverse thinking I am trying to find out exactly which of sigmas line up of 600 mm lenses I have ? I have got myself into a bit of brain freeze and I am puzzled to say the least.
Hoping you with all your knowledge you can give me the full spec ? . The standard sigmas I have checked are the a, s, c, and Art to no avail. Thanking you of a response. thank you.
David says
Good question, but I don’t know of one with 86mm filters and haven’t been able to find mention of one online. There are two of them I know of, both in the current lineup. The Contemporary version takes 95mm filters and the Sports version takes 105mm filters. I have the Sports version and have used the Contemporary one. On each, there’s a small, round silver badge on the side of the lens with either a C or S. But maybe there’s an older version? I’m not that familiar with Sigma’s older lenses.

I have a sigma 55mm 1.8, what filter would fit this?
David says
Sorry, but I’m not able to find any information about a Sigma prime lens of 55mm focal length online (and it’s not one I have or have used).
kevin mcglynn says
trying to find out what screw on filter fits the sigma 800mm f5.6 APO its to protect the front of lens
hope you can help
David says
According to the tech specs it takes a 46mm rear drop-in filter. I haven’t used that lens, and some rear drop-in filters are custom designed for a specific lens. Best bet would be to contact Sigma support directly–they can give you the most authoritative answer.
