The Tokina 70-200mm f/4 AT-X PRO FX VCM-S is a telephoto zoom lens designed for both FX and DX sensor Nikon DSLRs. Key features include:
- Compact Telephoto Zoom. The 70-200mm focal length is a popular choice for sports and portrait photography. Supporting both full and crop-frame sensor cameras, you get a focal length equivalent to 105-300mm on the later.
- Constant f/4 Aperture. Provides flexibility to shoot in moderately low lighting, though night sporting events will probably require a jump to one of the 70-200mm f/2.8 options.
- VCM Image Stabilization. The voice coil motor-driven stabilizer offers up to 3-stops of correction, enabling hand-holding images at slower shutter speeds without fear of camera shake.
- Ring-Type Ultrasonic AF Motor. Gives you fast, near-silent performance for both still and video use. The internal focusing design allows the lens to maintain the same overall form factor regardless of focus distance.
- Optics. Three Super-Low dispersion elements minimize chromatic aberrations throughout the zoom range, with multi-layer coatings to prevent ghosting and lens flare.
