Telephoto zoom.
the F4 telephoto zoom, which is popular for its high mobility and high image quality, is equipped with an image stabilization mechanism. the
image stabilization effect is about 4 steps in terms of shutter speed.
optical system adopts fluorite and UD lens.
also has high drip-proof and dust-proof performance to meet the demands of professionals.
lens configuration 15 groups of 20 sheets / shooting distance range: 1.2m-infinite / Filter diameter: 67mm / case (LP1224) / Hood (ET-74) / Ring tripod seat AII (W) sold separately / 1 fluorite, 2 UD lenses
image stabilizer image stabilizer image stabilizer image stabilizor's image stabilization effect mounted is about 4 shutter speeds. Even if
scaffolding is bad and the tripod cannot be used, you can easily shoot with your hand.
This sense of security is the charm of the image stabilization mechanism.
also, the optical system with a luxurious design that uses fluorite and UD lenses is unique to L lenses.
sharp delineation and vivid coloring add tension to the work.
highly practical with a dust-proof and drip-proof structure.
* Fluorite lens Thoroughly removes residual chromatic aberration that disturbs the sharpness of the captured image.
, the refractive index is remarkably low, it is low dispersion, and the transparency outside infrared and ultraviolet is also good, and almost complete removal of chromatic aberration is realized.
* UD lens ideal chromatic aberration correction with more lenses.
Ultra Low Dispersion (UD) lenses were developed under this theme.
optical material with low refraction and low dispersion characteristics, which is highly effective in removing secondary spectra, and abnormal dispersion characteristics such as fluorite, and has a performance almost comparable to one fluorite in two sheets.
* IMAGE STABILIZER Canon is the first image stabilizer mechanism in the world to be equipped with image stabilizer for SLR cameras.
it is effective in scenes that are likely to cause camera shake, such as handheld shooting of telephoto lenses.
* Ring USM USM (Ultrasonic Motor) = Ultrasonic motor is high torque / high response, quick focusing.
ideal motor for lens drive, with little operating noise.
* A technology that reduces the total weight of the moving lens by using a part of the inner focus lens configuration as a focus lens.
realizes high-speed and precise AF control, excellent holding balance, and compactness.
* Full-time manual focus This function allows immediate manual focus by simply rotating the focus ring after one-shot AF so that the photographer can final focus adjustment after autofocus.
* Dust-proof and drip-proof Various locations have a highly dust-proof and drip-proof structure that can handle professional harsh shooting situations, preventing the entry of dust and water droplets.

1.Image stabilizer: The image stabilizer's built-in image stabilizer has a shutter speed of about 4 steps. even if the
scaffolding is bad and the tripod cannot be used, it is possible to shoot easily with hand.


2. High image quality: Sharp delineation and vivid color development give tension to the work.
the optical system of the luxurious design which uses fluorite and UD lens together is unique to the L lens.


3. Quality: Highly practical with dust-proof and drip-proof structure.


IS/Image Stabilizer (IMAGE STABILIZER) is canon's first lens image stabilizer mechanism for SLR cameras.
, is the IS unit / image stabilization unit.


designed and developed according to the characteristics of each IS lens.
high-precision image stabilization is achieved in scenes that are likely to cause camera shake, such as at dusk, in dim rooms, museums where strobe light is prohibited, and hand-held shooting of telephoto lenses.


This is the world's first motor to be put to practical use by Canon.


1.High torque and high response for quick focusing.


2. Since the vibration of ultrasonic waves is converted into rotational energy, there is almost no operating sound. It has ideal characteristics as a motor for driving lenses, such as


.


Currently, USM has two types: "Micro USM", which enables compact lens size, and "Ring USM", which is ideal for large-diameter lenses and super telephoto lenses.
-ring USM-equipped lenses enable full-time manual focus, allowing quick focus adjustments without switching switches in AF mode after focusing with af.
