One fluorite and four UD lens elements provide excellent correction of chromatic aberration throughout the entire zoom range, delivering high-quality images with high resolution and contrast
Inner focusing, ring USM, a high-speed CPU and optimized AF algorithms for fast and accurate autofocusing
Optical Image Stabilizer provides up to four shutter speed stops of correction.
Three image stabilization modes (standard, panning, and during exposure only) provide excellent results for a wide range of shooting situation

The EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender from Canon is a high-performance super-telephoto zoom lens with a built-in 1.4x extender that converts the focal range and maximum aperture to 280-560mm f/5.6. The extender is located at the base of the lens and applied with a simple lever switch. The EF 200-400mm f/4L IS USM Lens features one Fluorite and four Ultra-low Dispersion optical elements that deliver sharper images with fewer chromatic aberrations. Super-spectra lens coatings minimize ghosting and flare and a Fluorine coating on the front and rear lens elements keep oily smears and fingerprints to a minimum.

From the Manufacturer

EF 200-400mm f/4L IS USM
Designed to satisfy the discriminating needs of sports and wildlife photographers, the EF 200–400mm f/4L IS USM Extender 1.4X is a high-performance super telephoto zoom lens with an optically matched built-in 1.4x extender for maximum versatility. With a simple flick of a switch, the zoom range can be quickly increased to 280–560mm (f/5.6). This capability is extremely useful in applications where it is not possible to change lenses quickly, while also protecting delicate equipment such as a digital SLR camera’s image sensor in environments with dust and high humidity. The EF 200–400mm f/4L IS USM Extender 1.4X incorporates one fluorite and four UD lens elements, which provide excellent correction of chromatic aberration throughout the entire zoom range for professional quality images with high resolution, contrast and color fidelity, while a 9-blade circular aperture helps deliver beautiful, soft backgrounds. It utilizes inner focusing, ring USM, a high-speed CPU and optimized AF algorithms for fast and accurate autofocusing. And, with Power Focus mode, focus shifts are quiet and smooth, which is essential for filmmaking. Image stabilization is effective up to four shutter speed steps, with three image stabilization modes (standard, panning, and during exposure only) providing excellent results for a wide range of subjects. Optimized lens placement and coatings deliver outstanding color balance, while helping to minimize ghosting and flare. The lens is highly resistant to dust and water, enabling shooting even in harsh conditions. A fluorine coating on front and rear lens surfaces repels dust particles and makes the lens easier to clean.

Pagarināma un īpaši spēcīga telefoto darbība

Profesionāla līmeņa 200–400 mm tālummaiņa ar nemainīgu f/4 maksimālo atvērumu. Iebūvēts pagarinātājs palielina fokusa garumu par 1,4x līdz 280–560 mm.

Maksimālais asums jebkādos apstākļos

Attēla stabilizatora tehnoloģija ļauj izmantot līdz četriem soļiem garāku aizslēga ātrumu nekā parasti, turklāt nav nekādu kameras vibrāciju. Ir trīs attēla stabilizatora režīmi, kas panoramēšanas laikā garantē efektīvu veiktspēju un tūlītēju stabilizēšanu tikai ekspozīcijas laikā.

Izturīgs un viegls korpuss

Magnija sakausējums piešķir papildu stiprumu un izturību, taču nepalielina svaru. Objektīvs ir izturīgs pret putekļiem un mitrumu, turklāt fluorīda pārklājums garantē ērtu objektīva elementu tīrīšanu.

Ātra un inteliģenta fokusēšana

Ātrs un gandrīz nedzirdams automātiskais fokuss. To garantē gredzenveida ultraskaņas AF motors. Kontrolējiet, izmantojot pilna laika manuālā fokusa apiešanas funkciju, kā arī fokusa apturēšanu un fokusa sākotnēji iestatītas vadīklas uz objektīva šķēršļa. EOS videoklipos ir pieejama funkcija Power Focus.
