4.1 This image was shot with a 28mm lens on a D600 FX camera. The area inside the red square is what would be captured with the same lens on a DX camera, like the D5200.

There are some upsides to this crop factor. Lenses with longer focal lengths now provide a bit of extra reach. A lens set at 200mm now provides the same amount of coverage as a 300mm lens, which can offer a great advantage for sports and wildlife photography, or when you can’t get close enough to your subject. Also, when using a lens designed for FX cameras, the sensor only records image information from the center of the lens, where the image is generally sharper.

Another advantage of DX lenses is that, because of their relatively small size, they are less expensive to manufacture and, therefore, less expensive than their full-frame counterparts.

Autofocus Concerns

The D5200 has no autofocus motor built in to the camera body, so therefore only lenses that have an integrated focus motor can perform autofocus functions with the D5200. This can lead to some confusion as to which lenses can be used with the D5200 with full functionality including autofocus.

As pointed out earlier, there are many letter designations on lenses. Nikon has its own specific designations, and third-party companies use their own. This can make shopping for lenses online a daunting task. You don’t want to order a lens and have it shipped to you only to find that the lens isn’t equipped with an autofocus motor so you’re reduced to manual focusing only.

Every company has its own letter designation for lenses with motors built in to the lens for autofocus, and some companies have more than one designation for different types of built-in motors that are included on different lenses.

Here’s a list of the acronyms and keywords to look for when shopping for autofocus lenses for your D5200:

• AF-S/AF-I (Nikon). Nikon uses AF-S to designate that the lens has the ability to autofocus with the D5200. In Nikon literature, you also sometimes see the term Silent Wave Motor or SWM. An older, rarer version is AF-I.

• HSM (Sigma). Sigma Corporation uses this acronym for its Hyper Sonic (integrated focus) motor.

• BIM/USD/PZD (Tamron). BIM stands for Built-In Motor, USD for Ultra Sonic Drive, and PZD for PieZo Drive.

• SD-M (Tokina). This company’s lens designation system is a bit tricky, so close scrutiny is required. I’ve seen Tokina’s integrated motors listed as SD-M (Silent Drive Motor), not to be confused with the SD designation, which is for Super-low Distortion glass. In Tokina literature, you also see Silent DC Motor listed as the name of the integrated motor. For DX-format lenses, all Tokina lenses with the DX II designation have integrated motors, while those with a simple DX designation do not.
