Tokina is one of the three main third-party lens manufacturers. They provide lenses for the big DSLR companies, namely Canon and Nikon. Like any lens you’ll find,  letters and numbers are written all over them. What do they mean?

These abbreviations let you know the features each lens has. For example, special coatings and lens elements that remove camera shake. These are just a few.

What Are Lens Abbreviations?

Lens abbreviations are very important. They let you know that this lens does what you need it to do. If you are looking for a specific lens for close up photography, then you might look for something that relates to macro, or 1:1 magnification.

With lenses containing more and more features, it’s almost impossible to write them all down in full form. This stops you from having to go through an entire camera manual to find out about your lens.

Let’s look at an example.

Tokina AT-X PRO DX 11-20mm f/2.8 Lens 

We can see a few abbreviations here: AT-X PRO, and DX. These mean that it is a professional zoom lens with a constant aperture, and specifically made for crop sensor cameras.

With a little practice and our article, you can read them easily.

FC –  Focus Clutch mechanism. the focus can change quickly between auto and manual focusing.

MC – Multi-Coating. A lens that has layers of coating to reduce flaring and ghosting for better quality.

One-Touch FC – One-Touch Focus Clutch mechanism. This is a new and improved focusing method.

SD –  Super-low Dispersion. These lens elements are superior in reducing chromatic aberrations.
