With an 18x zoom range, the Fujinon HA18X5.5BERD-S6 Premiere Series ENG/EFP Lens with Digital Servo & 16-Bit Encoders has the zoom range to cover sports from both up close and at a distance. With a close focus distance of about 16", you can get high energy close shots under a basket, or zoom in across to isolate a player in motion. Suitable for more than just sports, this lens gives you the focal length variety to work in a studio or get an intimate interview. It features 16-bit optical encoders for accurate servo zoom and focus, and the 18x zoom range can be augmented by engaging the built-in 2x extender.
The lens holds its f/1.8 maximum aperture from 5.5 to 62mm, ramping to f/2.9 at 100mm, with an optical design that losses only 0.1 stop of light at the wide end, and 0.2 stops of light from 100mm and longer, maintaining a close relationship between F-stop and T-Stop. Digital servo control of both zoom and focus is extremely responsive, and the lens incorporates an inner focus design that doesn't rotate the front of the lens when focusing. The Quick Zoom feature improves servo zooming speeds to as fast as 0.7 seconds from end to end.
