Here is an that shows this zoom up against near perfection in a prime lens. 3" 210mm minimum focus distance, just over half of that obtainable by the EF II lens. The model arriving with this lens is the LP1424. However, the sharpness increases slightly when you stop down. Professionals covering important events such as weddings will definitely find this lens to be of great value. At review time, most will consider the to be the primary alternative. Still, 24mm is not so wide that composition becomes too challenging. 24mm: 70mm: The 70mm results look very impressive from this regard while the 24mm results show a bit of magnification change happening. The 28-70's 95mm filters dwarf the 50's still-large 77mm filters. A relatively common lens aberration is axial longitudinal, bokeh CA, which causes non-coinciding focal planes of the various wavelengths of light, or more simply, different colors of light are focused to different depths. 2 x 4. With electronics driving AF, the rate of focus change caused by the focus ring can be electronically controlled and it can be variable, based on the ring's rotation speed. 7" 450mm 0. なんだかフワフワっとしたことしか書いてなかったり、オブラートに包んだような表現でまとめてあったり、なんならライカという哲学しか綴っていなかったりと… 高級ブランド品ですからね、大枚叩いて買ったことへの満足度とか、あるいは大金を使ったことに対して正当化したい気持ちが湧いているのかもしれない。 5 x 113. IS is useful for stabilizing the viewfinder and IS is very useful for video recording, substantially improving the quality of handheld recording. The hood has a durable, easy-to-clean mold-ribbed plastic interior and a push-button release makes the bayonet mount easy to use. I generally have along for each lens but with multiple densities often desired for , I usually carry an 82mm set along with step-up rings. And we can imagine that the latter was not an option. 8mm and 31. 7 700 3. 8L II the better purchase. It is there, but it is not strong. 7" 450mm 0. 7" 450mm 0. 15x 13. ついでに、 SIGMA WR CERAMIC PROTECTOR フード取付不可でした。 This lens covers the entire focal length range plus an extra 4mm on the wide end with a max aperture that, prior to the RF 28-70mm F2 L introduction, was the widest available in a standard zoom lens. 3 oz 575g 3. 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. 1 oz 880g 3.

Wide open, the corners at 28mm are slightly soft and do not change significantly until 70mm where the corners are noticeably softer. At 24mm, with a closer minimum focus distance, a subject measuring approximately 5. 2 545 3.。 As an "RF" lens, the Canon RF 28-70mm F2 L USM Lens is compatible with all Canon EOS R series cameras. The 28-70 has slightly less peripheral shading at medium and narrow apertures. Note that using a standard thickness will increase peripheral shading. The RF L-series lens look and feel is now firmly established and this lens fits that mold. 5 x 107. 保護フィルターだけでなく、可変NDフィルターやC-PLフィルターなど回転機構のあるものも含めて、対応品がリストアップされていれば安心できるんだけどねえ。 Vibration Shock Resistance Engineered to accommodate its optical system, the RF 28-70mm F2 L USM lens features L series level vibration shock resistance in the lens barrel, helping to maintain focus and settings even in turbulent situations. 0" 280mm 0. ケンコー・トキナーのZX ゼクロス フード取付可能! RF28-70mm F2L USM — アリモプレオ arimopleo 私も個人的に問い合わせなどしてみましたが、ケンコー保護フィルターは大丈夫のようですね。 While the review-time-latest Canon DSLRs are able to focus a Ring USM lens with good smoothness, these lenses still do not compare to the smoothness of STM lenses and there is considerably more focus chatter sound during Movie Servo AF. Here is an example of what this focal length range looks like: At review time, this lens is not compatible with any APS-C 1. That can mean a lot of prime lenses are needed and a lot of time-consuming, sensor-dust-inviting lens changes required during a shoot. The retailers I recommend below are the ones I trust for my purchases. The EW-103 has a molded rib interior designed to avoid reflections and a matte finish exterior to... The retailers I recommend below are the ones I trust for my purchases. 8 makes for a bright lens and the RF 24-70 compares very well in this regard. Data from the RF 28—70mm F2 L USM lens is transferred automatically to the camera body, facilitating near immediate correction for clear, detailed images. The L designation assures that this lens has professional grade build quality and reliability required by those who must bring home the assigned imagery. High Precision and Flexibility to Match Fixed Focal Length Lenses With a brilliant optical design and speedy performance, the RF 28-70mm F2 L USM delivers the flexibility, performance and image quality of 28mm, 35mm, 50mm and 70mm fixed focal length lenses in one discreet package. 9" 200mm 0. Consider renting. Spherical aberration along with spherochromatism, or a change in the amount of spherical aberration with respect to color looks quite similar to axial chromatic aberration but is hazier are other common lens aberrations to look for. Larger also is the 28-70's 95mm filter thread size vs. Note that the control ring is clicked by default and this ring's clicks are going to be audible in camera-based audio recordings. The higher a curve is shown on the chart, the better the lens is performing in the area the chart is measuring. ブランド力のあるメーカーの製品を使うのは大変気持ちがいいのも否定しない。 Otherwise, even the best optical performing lens is going to deliver poor image quality. なにしろ私の所有品は中古で5. 3 x 4. Should that fact change in the future, or should an R-series cameras' 1. Only this lens gives you both. The manual focus ring has an ideal resistance and adjustments are smooth and solidly centered with no unusual framing shift happening. 5" 850mm 0. 7" 500mm 0. That this single lens may be able to replace a kit of alternative prime lenses makes those three downsides much more tolerable. 5 x 125. Fast autofocus• This is a focus-by-wire or electrical manual focus system vs. These examples are from the center of the frame. 7 oz 670g 3. The centers show decent smoothness. This lens is not compatible with Canon extenders. A zoom lens does not change the ideal perspective for a photograph, and thus, adjusting to the ideal subject distance remains important. You will need an RF-mount camera the EOS R-series to mount this lens on, but this lens is good enough to justify buying an RF-mount camera if only to use this lens. 0 x 56. 0" 380mm 0. The manual focus ring is mid-sized and positioned in front of the zoom ring this is my strongly-preferred position. In the camera lens market, heavy weight, a large size and a big hit on the wallet often equates to awesomeness. 8 335 3. We didn't experience very much "hunting" at all, either in good or bad light, with the lens accurately focusing virtually all of the time. I prefer a linear adjustment speed and have the camera configured for such. The EF lens is slightly shorter and lighter but not having the RF mount means this lens requires a size, weight, and cost-adding for use on the R-series cameras. An interesting feature mentioned in this lens' press release is "focus breathing suppression". Little change in vignetting is seen at narrower apertures. This is a lens that is going to sell a lot of and future RF-mount-compatible models. 0" 381mm 0. In the real world, lens defects do not exist in isolation with spherical aberration and spherochromatism generally found, at least to some degree, along with axial CA. At 70mm, sight inward stretching is apparent, but the results are still relatively good. Here is a chart comparing the size and weight of similar lenses with a couple of additional RF lenses included. 6" 370mm 0. 6 x 87. If the blades are arranged opposite of each other an even blade count , the points on the stars will equal the blade count as two blades share in creating a single pair of points. With an extra stop of light, this means faster shutter speeds or lower ISOs for enhanced image quality, and marvelous performance when shooting movies. 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. Typical is for normal zoom lenses to have barrel distortion at the wide end and pincushion distortion at the long end with a transition to little or no linear distortion at a focal length closer to the wide end. In the real world, lens defects do not exist in isolation with spherical aberration and spherochromatism generally found, at least to some degree, along with axial CA. 28 ft. 5" 850mm 0. Once again, we have a Canon RF lens that delivers the complete package. By the 70mm end, smaller portions of a scene can be isolated and distant mountains will appear larger in proportion to closer elements. This is an ideal focal length range for videography needs. 21x 7. In the examples below, look at the fringing colors in the out of focus specular highlights created by the neutrally-colored subjects. While the attributes of this lens are very enticing to most photographers, only those with high budgets are going to be able to afford this one. As I've already completed the image quality discussion, we are primarily looking at the design from a "How did they do that? Do the corners need to be sharp? Announced alongside the similar-in-many-regards , the RF 24-70mm F2. ALL SUCH PROGRAMS, FILES, DRIVERS AND OTHER MATERIALS ARE SUPPLIED "AS IS. The image quality is also quite comparable with that of good fixed focal points. Looking at the specs and measurements, the shows the 28-70 being considerably larger and heavier. Vignetting can be corrected during post processing with increased noise in the brightened areas being the penalty or it can be embraced, using the effect to draw the viewer's eye to the center of the frame. A small amount of space is provided between the focus ring and the control ring, aiding in selection between the two. 21x 11. Here are maximum blur examples from this lens. The image quality difference between these settings is huge. 0 74. 8" 250mm 0. 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. If an R-series camera can be used, the RF lens is easily the better choice. Of ultimate importance is AF accuracy and from that perspective, all of the Nano USM-driven AF systems to date have performed impressively. 6 67 2012 33. Focus shift is not a problem. For example, often when the subject is a person and a wide aperture is being used, the entire surroundings are frequently desired to be out of focus with the blur helping the subject to stand out. 8 images from this lens show from 2 to just under 1. 70mm: These results are looking superb. The review-time current RF standard zoom lenses are shown in the above images. 0 72 2006 33. If AF is being relied upon, it needs to be accurate. Available from October 2018. 21x 6. However, for those, is a great option. Below, the 24mm image is a top-left quarter of the frame and the other two examples are full images reduced in size. Where you buy your gear matters. I can't see to walk around in light conditions that I can focus this lens in. 30x magnification capability. But again, why would you go to all that trouble? Protection from light is going to be about as good as possible at the wide angles with the made-for-28mm design being smaller than a designed-for-70mm hood would be. Wide apertures are useful for stopping action, both that of the subject and that of the camera, in low light levels while keeping ISO settings low. 8L II. 7 x 1. While that setting is often my preference, this lens' variable focus adjustment feature is dialed in very well with the rate required for the faster speed is set high enough that I do not inadvertently reach it and the variable speed setting is what I have been using for this lens. A new feature for RF lenses is the Lens Control Ring at the end of the lens barrel, which can be used to control certain key camera settings. Putting the sizes into visual perspective is usually advantageous. Alternatively, click 'Open folder' to open the folder on your computer that contains your downloaded files• 8 L IS USM Lens for only a short period of time? A quiet "shhhhh" sound of the optical group movement is heard during AF with an occassional light clunk being heard upon completion of the movement. 5" 634mm bulbs in the image below were captured at this lens' minimum focus distance. 2 600 3. This range is lacking from a wide angle perspective, but it has a very attractive long end, making it a great portrait focal length range. The retailers I recommend below are the ones I trust for my purchases. 0 x 2. This one's threads are 95mm wide and that means the filters are large and the quality models you want are expensive. A slim model such as the or is highly recommended. 2 x 39. Like most other recent L lenses, the RF 28-70 F2 L features fluorine coatings on the front and rear lens elements to avoid dust adhesion and to make cleaning easier. Below are some examples of out-of-focus specular highlights. Obvious differences to get out of the way are the 28-70's zoom range versatility and the 50 F1. ライカストアに行ってみるべし 一昨年のことになりますが 祇園にありますライカストアの京都店にふらりと立ち寄って、…• 09 x 5. 3 x 4. 5 x 107mm 77mm 2005 31. Need a high maximum magnification? The depth of field remains well-centered as this lens is stopped down. Covering the angles of view ranging from wide-angle through normal and on to short telephoto, the Canon RF 24-70mm F2. For photographers and moviemakers who would prefer a silent control ring, the clicking mechanism can be removed by a Canon service provider for a fee. 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. 8 L IS USM Lens is Canon's best-ever option for this need. 4 805 3. 7 700 3. But, having a zoom lens can very dramatically speed up a shoot by eliminating most or even all lens changes. Polariser users should be pleased that the huge 95mm filter thread doesn't rotate on focus. 8 and it becomes very slightly advantaged in most comparisons. 7" 170mm 0. The EF lens has slightly stronger barrel distortion at 24mm than the RF lens has at 28mm, but the advantage reverses at the equivalent 28mm setting and reverses again at 35mm with the RF regaining the advantage. The 50mm result is still looking great with the colors reversing and appearing in moderately-strong levels at 70mm. ライカといえば高嶺の花すぎて自分には関係ないと思い続けてきたのですけど、すーっと自然な流れで買うに至ったので、そういう運命だったのかもなと感じています。

I'm sure that there is a good reason for that and this is a design quality I like. 4 77 2017 15. The rear-positioned zoom ring is ideally-located behind the focus ring. The 24mm and 40mm examples look excellent. The shadow is slightly increased with the hood in place. Even the lens' aperture changes are quiet and smooth. This negatively impacts photographers intending to use focus stacking techniques, videographers pulling focus, and anyone very-critically framing while adjusting focus. 8L USM Lens was discontinued in 2002, you might have to search hard to find a reliable copy of this lens. とはいえ金額的にはやはり清水の舞台から飛び降りる覚悟であったことは間違いない(笑) 以前の私と同じように、高額なブランド品で自分にはあまり縁がないと考えている方も多いでしょうから、いつか来るかもしれないその日のために、私自身が購入に至るまでをここに記しておこうと思います。 8 oz 900g , this lens is a mid-sized, mid-weight lens. Focusing The combined performance of a camera and lens' autofocus system is critical to realizing the potential image quality of the combination unless using manual focus. Edge• 22年間がんばってきた自分へのご褒美として、本当の意味で自分のために何か買ってもいいのかなと。 24x 17. While the visual difference shows the RF lens consuming more volume, the specs and measurements in the shows these two lenses being very similar in size and weight. 5 x 111. Use the site's tools to create your own comparisons. 8-112mm. 8 L has a very short 8. 8 oz 475g 3. The 28-70 has slightly more barrel distortion at the wide end and less pincushion distortion at the long end. じつに困った。 This lens is well-suited for commercial photography and is ready to capture interior and exterior architecture, cities, countrysides, flowers, medium and large products and much more. 5 x 84. 5 103. 82mm. 8 L IS Lens features fluorine coatings on the front and rear lens elements to avoid adhesion of dust and liquids and to make cleaning easier. 6mm 82mm 2007 16. 3 seconds. If the zoom range versatility is important to you, the 28-70mm lens should be in your kit There are many other lenses that could be compared to this one. The 70mm corner is again looking very good aside from some lateral CA separating the color spectrum modestly. 8 L IS USM Lens is compatible with all Canon EOS R series cameras. Positioned above from left to right are the following lenses: Canon RF 28-70mm F2 L USM Lens The same lenses are shown below with their hoods in place. 6mm 77mm 2006 7. The RF 24-70mm F2. Lateral CA shows as color fringing along lines of strong contrast running tangential meridional, right angles to radii with the mid and especially the periphery of the image circle showing the greatest amount as this is where the greatest difference in the magnification of wavelengths exists. 18x 19. でもそれはそれで否定する気もないんですよね。 Autofocus of course happens more slowly under these conditions, but if there is some contrast available, this lens gets the job done. 2 x 3. The focal length setting makes little difference in the image quality, an unusual quality for a lens that traverses the wide angle to short telephoto range normal is for there to be an image quality decline at the longer focal lengths. There are no hard stops at either end of the range, making it more difficult to set focus at infinity. a direct gear-driven system. 4 x 93. 6 83. 4 x 105. 4" 88. 1 x 4" 78. Combine those qualities with a general purpose focal length range and the end result will be a most-used lens in many kits. 3 x 4. 5 750 3. 4 88. Barrel distortion is slightly evident at the 28mm wide-angle focal length, but it disappears completely by 35mm. Delivering highest standards of descriptive performance at wide open aperture truly provides you the convenience of performing the work equivalent to a few prime lenses. The focusing ring is wide enough to find easily, and it has a ridged, rubberised grip band. ただし一部の高級コンパクトを除いてその性能はスマホカメラと拮抗あるいは使い勝手において敗北し始めている。

Dust- and Water-resistant For reliable performance even when weather conditions get difficult, the RF 28-70mm F2 L USM lens features dust- and water-resistant construction in the lens mount, switch panel and all rings. Located towards the front of the lens and effectively adding a third dial to the EOS R camera's main dial and quick control dial, the control ring has a tactile, easily distinguished surface and features a clicking mechanism that provides tangible feedback for confident use while looking through the viewfinder. 5 x 4. The bigger lens has a bigger price. Canon's engineers have not provided a reason for this design decision, but image stabilization adds size, weight and cost to a lens. 写真:ミノルタMロッコール40mm F2を装着 ボディ端にEVFを搭載したレンジファインダースタイルのため、いわゆるペンタ部が存在しないフラットな上面も気に入っている。 。 。 。 。 。 。
