Rounding out your kit, the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens with Accessories Kit from B&H bundles the telephoto zoom lens with a 77mm UV filter and a lens cleaning kit.
Canon EF 100-400mm f/4.5-5.6L IS II USM Lens
A long-reaching telephoto zoom characterized by a sophisticated optical design and advanced image stabilization technologies, the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens is part of the esteemed L-series developed for full-frame EOS DSLRs. One fluorite element and one Super UD element have been incorporated into the lens' construction, and both help to reduce aberrations and distortions throughout the zoom range in order to deliver notable clarity, image sharpness, and faithful color reproduction. An Air Sphere Coating has also been applied to lens elements in order to reduce lens flare and ghosting for more contrast-rich imagery. Benefitting the optical components of the lens, a four-stop effective Image Stabilizer helps to minimize the appearance of camera shake and can be dedicated to different styles of shooting. Furthermore, a redeveloped rotation-type zoom ring pairs with an internal focusing mechanism, and an Ultrasonic Motor, to deliver quick and intuitive handling to benefit handheld shooting. Positioned as a versatile option for sports and wildlife photographers, this lens' list of attributes make it a viable telephoto zoom for a variety of shooting applications.
Housed within a weather-resistant barrel, this lens also features fluorine coatings on the front and rear elements for protection against fingerprints and smudges from affecting image quality. Zoom control is complemented by a dedicated tension ring for adjusting zoom torque. Additionally, other refined design elements include a tripod collar that can be attached or detached with the lens mounted to the camera and an included lens hood that permits easy control over specialty filters with the hood in place.
Telephoto zoom is compatible with full-frame EF-mount DSLRs, as well as APS-C-format models where it provides a 160-640mm equivalent focal length range.
One fluorite element and one Super Ultra-Low Dispersion element help to correct chromatic aberrations throughout the zoom range for a high degree of sharpness, clarity, and color accuracy.
An Air Sphere Coating (ASC) has been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.
An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. Additionally, three dedicated image stabilization modes are available—Standard, Panning, and During Exposure Only—and can be selectively employed to suit a variety of types of shooting.
A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
The rotation-type zoom ring offers precise adjustment between zoom positions, especially when shooting handheld, and a zoom torque adjustment ring enables easy setting of the zoom tension for personalized control.
A weather-resistant design protects the lens from dust and moisture to enable its use in inclement conditions. Additionally, fluorine coatings have also been applied to the front and rear lens elements for further protection against fingerprints and smudging.
Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
A redeveloped tripod collar can be attached or detached from the lens without having to remove the lens from the camera.
The included ET-83D lens hood incorporates a side window for easier adjustment of rotating filters with the hood in place.
Chiaro Pro 77mm 99-UVBTS Brass UV Filter
The Pro 77mm 99-UVBTS Brass UV Filter is Chiaro’s top-performing protective UV filter offering 99% light transmission. It’s ideal for photographers who demand the highest-quality glass and other essential features for uncompromised image fidelity and premium construction.
To achieve superior 99% light transmission, Chiaro uses highly-polished Schott glass, multi-coating, and additional advanced elements that improve the filter’s light transmission. A scratch-resistant coating minimizes scratching of the glass and helps assure that water, oil, dust, and fingerprints are removed with a gentle wipe. The durable brass filter ring is designed to screw on and off effortlessly, and it’s thin to prevent vignetting when used with wide-angle lenses. Side knurling is crafted to help ensure that you’ll have a firm grip when attaching or removing your filter.
Image quality is what matters most at Chiaro. The company has tested and combined many features and essentials to achieve superior image quality and the highest light transmission. To help take the confusion out of selecting a filter, Chiaro prominently displays the light transmission levels so that you can choose the perfect filter for your lens and photo session.
99% Light Transmission
Protecting your lens doesn't mean you have to lose optical quality. By using highly-polished Schott glass and advanced coatings, Chiaro can offer a 99% transmission rate, which is the highest possible transmission rate for glass. And the company verifies the ratings with ISO certified lab testing.
The layers of advanced resistance coating on the filter are designed to resist moderate scratches, and allows you to easily clean your filter. Water beads up and rolls off your filter, and oil and fingerprints can come off with a gentle wipe. Dust and debris won't adhere to the filter and can be removed with a puff of air.
Polished Schott Glass
Glass that's polished to perfection is essential to achieve a high level of light transmission. The Schott glass in this Chiaro filter is highly-polished for flatness that ensures superior optical clarity.
Multi-coating enhances light transmission to the demanding level set for all Chiaro filters. It reduces unwanted internal reflections and ghosting that can compromise your images.
The filter blocks UV light and reduces the bluish cast of daylight that can affect color accuracy, especially at higher altitudes.
The durable brass filter ring offers a substantial, premium feel. The unique properties of brass minimize the chance of jamming or binding when you're screwing the filter onto your lens or stacking filters.
Measuring only 3.2mm, this filter is slim enough to use on wide-angle lenses without experiencing vignetting.
Top and Side Knurling
In addition to top knurling, Chiaro added side knurling that helps offer better options to grip the filter when you're attaching and removing it, or when you're stacking filters.
It takes two full turns to mount the filter on your lens. This feature will securely hold your Chiaro filter through the most demanding photo shoots.
The front threads on the filter allow you to stack filters by screwing them onto your Chiaro filter.
Sensei OC-CK Optics Care and Cleaning Kit
Keep your optical surfaces clean with the Sensei Optics Care and Cleaning Kit. This kit contains a pack of lens tissues, a lens cleaning pen, a bulb air blower, a paint brush, a lipstick brush, lens cleaning fluid, and a 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.
