Sigma 105mm F/2.8 DG DN Macro Art Lens

While it is a dedicated macro lens, the 105mm focal length and F2.8 aperture make it an excellent portrait lens. It provides beautiful subject separation and a flattering compression that works very well for headshots and close-up portraits.

The de-click switch allows the aperture ring to rotate smoothly without the tactile 'clicks' at each f-stop. This is a vital feature for videographers who need to make silent, seamless exposure adjustments while recording.

Yes, the lens features a dust and splash-proof construction. It is designed to withstand challenging environments, making it a reliable choice for outdoor macro work where you might encounter moisture or dust.

The lens uses a high-speed, quiet internal focusing motor that is very capable for general photography. However, keep in mind that macro lenses have a longer focus throw than standard lenses, so for extremely fast action, you may want to utilize the focus limiter switch to restrict the range and improve speed.

The minimum focusing distance is 300mm (about 11.8 inches). This distance is measured from the image sensor, meaning you will have a comfortable working distance from your subject when shooting at the 1:1 magnification ratio.

Yes, the lens features a programmable AFL (Autofocus Lock) button. You can assign various functions to this button through your camera's menu, allowing you to customize your workflow for quicker access to settings you use most often.
