Rounding out your kit, the Canon EF 70-200mm f/4L IS II USM Lens with Accessories Kit from B&H bundles the sleek telephoto zoom lens with a 72mm UV filter as well as a lens cleaning kit.
Mixing a relatively compact, lightweight form factor with updated stabilization and performance, the EF 70-200mm f/4L IS II USM from Canon is an impressively versatile telephoto zoom. Well-suited for a range of subjects, from events to portraiture to sports, this zoom is characterized by its constant f/4 maximum aperture to strike a balance between consistent performance and portability. Its optical design includes a pair of UD elements and one fluorite element to greatly reduce chromatic aberrations and color fringing. This optimized design, along with a Super Spectra coating, also helps to control flare and ghosting for greater contrast and color accuracy when working in harsh lighting and backlit conditions.
Version II of this popular lens also sees the inclusion of a revised Optical Image Stabilizer, which now compensates for five stops of camera shake and offers three distinct stabilization modes to suit different shooting applications. A ring-type USM and internal focusing mechanism also afford quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Additionally, this lens is weather-sealed for use in trying environmental conditions.
Keep your optical surfaces clean with the Sensei OC-CK Optics Care and Cleaning Kit. This kit contains a pack of lens tissues, a lens cleaning pen, bulb air blower, paint brush, lipstick brush, lens cleaning fluid, microfiber cleaning cloth, and see-through mesh travel case to put everything in. This kit can be used to clean a variety of different optics and glass. You can use the air bulb blower and any of the three supplied brushes to initially remove dust from the surface. Sensei recommends applying a small amount of the alcohol- and ammonia-free cleaning fluid directly to the lens tissue. Then, gently rub in small circular motions to remove stubborn smudges or fingerprints from the glass. For those more stubborn blemishes or smudges, the lens pen is very effective.
