Filter Thread Size??

Recently we encountered a few customers purchased the wrong filter size just because they misinterpreted the focal length as the actual filter thread size when purchasing a UV filter for their new lenses. Daily, we encounter dozen of customers ask us whether Canon Kit Lens 18-55mm uses a 55mm size filter. Some even placed order in shopping cart ordering the wrong size for their lenses.

In this post, we would like to aid beginners in purchasing the correct filter sizes for their lenses. Along with picture, we will show you how to check which size does the lens that you own can fit.

Alright, check out the picture below, have a look at the symbol beside the figure 58mm, which looks like this: ø. This symbol tells you that the lens can fit a 58mm size filter.

For some other lenses, sometimes it's not written at the front of the lens, like a few lenses below, the filter thread size info can be found at the side of the lens.

Image on the left: Nikkor 18-135mm, the size is 67mm.

2nd image on the left: Sigma 10-20mm f4-5.6, the size is 77mm

3rd image on the left: Tamron 17-50mm f2.8, the size is also 67mm.

Hope this post will clear things up for everyone. Thanks for reading and enjoy photography ^^
