Like any field, photography is ripe with acronyms for equipment and acronyms that are brand specific as well. Because nothing makes it more challenging than not being universal and of course hard to follow for those entering the field.

Seasoned professionals will catch themselves rattling off the acronyms to those who ask us questions and then find themselves backpedaling to further explain what they mean. I know I do it fairly frequently because after a decade the acronyms are faster and more convenient for me.

So the first thing to consider is that there are two common camera sensor types. Full frame and Cropped sensors. Each is important as they each pair with specific lenses and mixing those can result in vignettes that are not intentional.

Another important feature in photography is image stabilization which is a feature that allows you to use the camera with lower shutter speeds. For mirrorless the Image stabilization feature is sensor-driven but for DSLR it is tied to the lenses and makes it important to understand those designations.

When using autofocus there are specialized motors that move the lens elements into focus. The purpose and advantage are to do so quickly and efficiently as well as quietly. This is a big advantage to sport and wildlife photographers and as such, the designation for autofocus speeds and abilities vary between brands.

There are many many acronyms out there in photography. These acronyms focus on what you will see on the side of your lens or when purchasing a lens. This guide can help make it easier to understand what your lenses and gear are capable of as well as what you may wish to purchase to upgrade.
