556:『Canon RF70

The 70mm focal length is also important and it is the other full extent of the zoom range, potentially another weak setting. The camera's AF system can produce better focus precision if the image it sees is stabilized. 8 L IS USM Lens It is this lens' retracted size that is dramatically smaller than all of the other lenses in its class. Street photography, often done in cities, is another great use for the 70-200mm range. ALL SUCH PROGRAMS, FILES, DRIVERS AND OTHER MATERIALS ARE SUPPLIED "AS IS. 6L IS II USMを使っている感覚になりました。 Kenji Shinohara Optical Design : Using two Nano USM units enables us greater freedom over lens group placement, which links to high image quality. Canon does have RF extenders, the and , but again, they are not compatible with the RF 70-200. The fluorine coating makes a noticeable difference that is especially appreciated in the field. 5mm, which is not a big difference from that of the 199mm. An interesting feature mentioned is this lens' focus system design aids in reduced breathing. ISO settings were mid-level not optimal for image quality discernment , light noise reduction has been applied 2,3 or 3,3 , and I opted to brighten all images shared here see the settings and adjustments listed for each image. ビルの隙間によって作られた光の帯を縦断するように人が歩いていました。 With the control ring, you can directly adjust settings such as shutter speed, lens aperture, exposure compensation and more. In addition to stopping action in low light, the wide aperture invites handholding the camera in much lower light levels. , a leader in digital imaging solutions, is excited to introduce the compact and lightweight RF70-200mm F4 L IS USM and the RF50mm F1. 楓の赤と影の黒のコントラストがはっきりとしており、透き通った葉の葉脈までしっかりとシャープに描写されています。 8L IS USM 大三元レンズの一本である70-200mm F2.

The first visually noticeable improvement is the customizable control ring that has become synonymous with RF lenses. This RF mount version promises the same functionality, if not more. However, telephoto focal lengths are an extremely important part of a landscape kit. Price and Value This is a top-of-the-line lens and the price tag reflects that status. Also, like the other Nano USM lenses, this one focuses very smoothly. As a rule, the more the aperture blades, the source of the star effect, are narrowed, the better the starburst effect appears. The illustration below shows the total length when fully retracted and extended. When shooting at the widest apertures, including for portraiture, depth of field is often shallow and the plane of sharp focus less-frequently includes a corner, making corner sharpness less important. In the examples below, look at the fringing colors in the out of focus specular highlights created by the neutrally-colored subjects. Three stabilizer modes• desired, and this lens does not otherwise exhibit such. Cameras featuring Dual Pixel CMOS AF and Movie Servo AF make video recording very easy and Nano USM lenses are very well-suited for this task. The foot is not removable and replacement lens feet will require the entire ring to be replaced. Note the faces of the models are considerably off-center, showing performance toward the periphery of the image circle. The red ring and the "L" in the moniker indicate this lens' inclusion in the exclusive , the company's best-available, professional-grade lens models, built tough for the rigors of daily professional use. While I don't consider myself to be the steadiest photographer, this testing is done under ideal conditions, indoors on a concrete floor. Despite the reduced proportions, overall image quality was not sacrificed a bit more peripheral shading and even improved in some regards better flare resistance. To keep apprised of the latest news from Canon U. 8, move in close to your subject and watch the distracting background melt away. If capturing environmental wildlife portraits or captive zoo wildlife, this focal length range may be perfect. Compare that to the EF predecessors' 47. With the right lens profile and software, lateral CA is often easily correctable often in the camera by radially shifting the colors to coincide though it is always better to not have the problem in the first place. 8L IS USM, in consideration of how users will probably be zooming in and out very frequently, the control ring is placed nearer to the mount, reducing the chances of turning the wrong ring by accident. This lens invites subject framing ranging from full body portraits at 70mm to tight headshots at 200mm and these mid-telephoto focal lengths naturally push the focus distances far enough away to avoid perspective distortion, including large-appearing noses, yet not so far that communication with the subject becomes difficult. This feature is provided by the lens electronically adjusting focus while zooming and a strong defocusing can be momentarily seen with a fast zoom adjustment. "The lens also incorporates a floating focus control, another Canon first, that drives the two lens groups individually while using the two aforementioned Nano USM motors. The front and rear elements are fluorine-coated, helping dust and water drops to shed off or easily blow off of the front and rear lens elements and makes cleaning other more problematic issues, such as fingerprints, much easier. Those committed to the R-series need to also account for the mount adapter size as illustrated below. The effect of different colors of the spectrum being magnified differently is referred to as lateral or transverse CA Chromatic Aberration. Be sure to observe the sharp plane of focus for your judgments. Focal length range and constant aperture The 70-200mm focal length range is perfect for landscape images that decisively capture elements from nearby to far away. The two Nano USM units provide independent control over the focusing lens and floating lens. Check out the sharpness of the model's face and follow the sharpness of the dress circles falling in the plane of focus. To that point, the Canon RF 70-200mm F2. " [Canon] Nano USM acts like an ultra-fast version of STM AF, combining the benefits of a high-speed Ring USM actuator with an STM system stepping motor's quiet and smooth, direct, lead screw-type drive system. Removal is sometimes very challenging and, in some cases, flare effects can be quite destructive to image quality. Image Stabilisation of 5 stops• That was one of the first questions in my mind with the words of Canon's engineers offering strong encouragement in this regard. Quickly hike up a big mountain and shoot from an unstable position in strong winds and a significantly faster shutter speed is going to be needed. The EOS R system's 12 pin communication system enables the Digital Lens Optimizer, which works in-camera to combat aberrations and image deterioration, especially in the edges of the image frame when shooting at a large aperture. Astigmatism is seen as points of light spreading into a line, either meridional radiating from the center of the image or sagittal perpendicular to meridional. As the aperture narrows, the entrance pupil size is reduced and the mechanical vignetting absolves with the shapes becoming round. 8 lens is a nearly mandatory member of any professional or serious amateur photography kit and these lenses are often among the most frequently used. The physical properties of light passing through a lens prevent the same amount of light from reaching the edges of the circle as the center, resulting in a darkening of the corners, referred to as vignetting or peripheral shading. Note that the control ring is clicked by default and this ring's clicks are going to be audible in camera-based audio recordings. Axial CA remains at least somewhat persistent when stopping down with the color misalignment effect increasing with defocusing while the spherical aberration color halo shows little size change as the lens is defocused and stopping down one to two stops generally removes this aberration. I only have slim circular polarizer filters and I'm not able to rotate them at all through the opening. 8 L IS USM to perform AF shooting to capture a subject at close-range with the focus distance approximately set to the Tele-end 200mm , the image may become slightly front-focused.
