Sigma 100-400mm。 Sigma 100

I preloaded a comparison that you might find interesting and there are many other good comparisons to be made. 3 DG DN OS Contemporary gives photographers a "super telephoto" angle of view with a focal length of up to 800mm while they enjoy the benefit of the compact system. AFL button• The most easily recognized type of CA Chromatic Aberration , lateral or transverse CA, shows as different colors of the spectrum being magnified differently with the mid and especially the periphery of the image circle showing color fringing along lines of strong contrast running tangential meridional, right angles to radii as this is where the greatest difference in the magnification of wavelengths exists. The switch bank is not as comfortable to grasp as just in front of it and I find my left hand typically holding under the focus ring. LENS COMPATIBILITY CHART Check the compatibility of lenses with your camera make and model. It also features the AFL button to which the user may assign select functions on the camera side, and the focus limiter switch that allows optimizing the AF range according to the purpose of shooting. This flower is just-over 3" 75mm in width. 6" 2200mm 0. Below is the worst-case result I produced. This helps to ensure the composition of images quickly. 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. As this helps reduce any strain on the camera body, photographers can shoot long hours without worrying about it. A few days later, my wife informed me that there was a garter snake in front of our house. 20x. The images were processed in DPP using the Standard Picture Style with sharpness set to only "1". 5-6. I got distracted at this point in the review. To clarify: I was not afraid of the snake, but the opposite was not true. If you are looking to zoom and have an e-mount camera, this lens is for you. The same weather pattern provides for dramatic skies at sunset and I of course stayed for that event. Four SLD glass lens elements and an optimized power distribution help minimize optical aberrations. 26x 102. 39 x 7. 4 km through the woods to a view overlooking some fields where I predicted the special subject should become visible and.... This lens meets expectations, but does not exceed them. I photographed the storm until I began to get rained on. The longer focal lengths showed less of this issue and the above performance has not proven to be an issue either. At 100mm, the sharpness in the center is almost as high as over the rest of the range, but the sharpness drops off a bit toward the corners when you photograph a flat subject at a short distance. 39 inches 7. 1 x 5. VIGNETTING, FLARE AND DISTORTION This lens does not suffer much from vignetting. Distance ranges provided are Full, 19. 3 ISO Setting: 640 Description: I love the wildlife we have in our suburbs. 2mm 95mm 2016 68. The 100-400 C zoom ring rotates in the Canon-standard direction opposite of the Nikon standard. The Sigma is smaller and lighter and uses smaller filters 67mm vs. Here are some real-world examples showing the extreme bottom left corner of an ultra-high-res 5Ds R frame. You will buy a 100-400mm more for the 400mm mode than for the 100mm mode. While "Artistic" and "Sports" give direction toward their suggested use, "Contemporary" is more vague. 00 millimeters 35 millimeters Minimum Aperture 5 6. Sigma USA provides a 4-year limited warranty. 9" 1750mm 0. 8 Maximum Focal Length 400 600 millimeters 400 millimeters 400 millimeters 400. If lens elements refracted all visible wavelengths of light identically, a lens designer's job would be a lot easier. Quite sharp. 3 DG OS HSM Contemporary comes with a large plastic lens hood. The SIGMA 100-400mm F5-6. It does not have any noticeable weakness but is good at almost all points. fields. Surprisingly, this lens does not show much sharpness degradation with the 1. 00 Sold By Color Black Black Black Black Black Black Compatible Camera Mount Canon EF Canon EF Canon EF Sony E Canon EF, Canon EF Canon EF-S Focus Type Auto Focus Auto Focus Auto Focus Auto Focus Auto Focus Ring-type ultrasonic Item Dimensions 3. The image quality this lens delivers competes with much more expensive models and this is a full-featured lens well, the tripod ring is missing. 2" 105. 7 out of 5 stars 4. 0 1. 71x. In addition, Mode I normal and II panning mode are provided via a switch. 3 DG OS HSM is a lens from the Contemporary series. The lens might be slightly less robust than Sports versions, but it nevertheless feels very solid. You do not always get that result, but it is possible. Again, stopping down resulted in very little change. Thank you Sigma for the 100-400mm F5-6. This may be visible in architectural photographs or other types of photography with lots of straight lines. While there is some plastic feel to the lens, the quality finish gives it a nice touch and provides a very classy look. In between, there is a lock to secure the zoom, and at the back is a whole range of switches for autofocus and image stabilization. Dust-proof and splash-proof mount. The hood also features a rubber construction and a non-slip groove to make it easy to hold in a variety of shooting situations. 3 can blur the background when used at a close focus distance. The lenses in this series continue to impress and gain popularity — just don't limit the lens' use to its letter designation. To potentially reduce autofocus hunting, autofocus distances can be restricted using the focus range limit switch. Since Sigma reverse engineers vs. You rarely see that with zoom lenses. Yes, that appears to be a mushroom cloud, but no, the local town was not attacked. I'll talk more about the later, but the dock permits this lens' OS to be further configured to one of three settings described by Sigma as: Dynamic View Mode — This mode offers a recognizable OS effect to the image in the viewfinder. 0 x 193. I mounted a and went outside. The second five images, shown in the right column, were captured with the lens pre-focused to the background. 3 x 10. The 100-400 C is sharp wide open and there is little differentiation between focal lengths aside from the 400mm results being very slightly softer than the wider options. Now spring is here the native birds are active particularly in the mornings Being retired I try and get up early most mornings and always have my camera with me. All that said, this is the normal design for lenses in this class and it works fine. Dust- and splash-proof bayonet• I'll restrain myself from sharing more of the images from that evening, but a couple of hours with the Sigma 100-400mm C netted me a quite-significant number of images I liked. The image sharpness and overall quality of the 100-400 L II launched it to immediate success. Sometimes, lazyness is a good reason to use the 100-400mm focal length range. With MC-11, also usable on Sonys CONS• We prefer the characteristic of the Sigma. This zoom range is a great choice for chasing the kids outdoors such as at the park or at the beach. Four SLD glass lens elements and an optimized power distribution help minimize optical aberrations. While 400mm may still feel short in front of a full frame camera when photographing deep into large-field events, in front of an APS-C model where it provides an angle of view equivalent to a 160-640mm lens on a full frame camera, 100-400mm can cover a very significant portion of even large soccer, football, field hockey, lacrosse, etc. This Sigma telephoto zoom even has a gasket on the back to prevent the penetration of dust and moisture through the mount. 3 DG OS HSM C Lens is available in Canon reviewed , Nikon and Sigma mounts and the Canon and Sigma versions can be used on a Sony E-mount camera body via the. Whether the reason you cannot get closer is motivated by a safety concern from or for the subject or just because there is a physical barrier to getting closer, this might be the right focal length range to have mounted on the camera. It is threaded for 67mm filters. The lens has a minimum focus distance of 112cm 44" at wide-angle and 160cm 63" at telephoto, with a max magnification of 0. In the press release, Sigma mentioned a "dust- and splash-proof design", hinting that the lens has sealing throughout. This lens is not a good choice for indoor sports or for anything else that moves in low light. The advantages of a narrow aperture, because the lens elements can be reduced significantly in size, include lighter weight and lower cost. Our standard lab tests are great for seeing the capabilities of this lens use the "Image Quality" link to see these results , but I also like to share some real world examples. Note that a thin-ringed filter is difficult to access with fingertips due to the thickness of the lens barrel at the threads. 0 max aperture, but... That is hardly relevant. Sigma has obviously made light weight a priority for this lens. I was set up and waited for him to take off in flight. 2" 86. 6m - 19. Because they do not, we get aberrations caused by various wavelengths of light being magnified and focused differently. The 100-400 C internally focuses quietly with only some faint shuffling heard and it focuses fast in the default "Standard AF" mode. Yes, now I am very distracted and I'll take you along for the tangent as it helps to illustrate the value of this focal length range. 4x and 2x increase in both focal length range and MM values. 3 DG OS HSM C Lens mounted to a along with a wide angle lens for a trail run. 0" 95. It does not and I'm seeing only little evidence of any of the other issues. With great image quality from a feature-filled package, this lens warrants kit-addition consideration. I like fast. In addition to allowing more light to reach the sensor, increasing the aperture opening permits a stronger, better subject-isolating background blur at equivalent focal lengths. The bottom switch is for setting one or two custom settings. They are similar enough that I thought I had not properly configured the custom modes and re-docked the lens to try again. 3 DG DN OS Contemporary comprises 16 groups and 22 elements, with one FLD and four SLDs used for the effective correction of aberrations and distortions. If this lens is pointed downward and some movement is occurring such as walking , gravity will extend the lens to a longer focal length. 8, but you have twice the range. Yes. To test AI Servo continuous AF accuracy, I photographed a soccer match one of many images I like from this match is included in the focal length discussion earlier in the review. A downside is that lateral CA is increased. 3" 2700mm 0. Below that is a switch to limit the autofocus range, and below that, a switch for image stabilization. 4" 2600mm 0. 5 x 203. Focusing The 100-400mm Contemporary Lens' AF system, like most of Sigma's other lenses, is driven by Sigma's HSM Hyper Sonic Motor. These combine to create a less sharp, hazy-appearing image quality at the widest apertures. 8 x 3. Another good reason to use medium and long telephoto focal lengths is for the compressed perspective the narrow angle of view invites. slight risk of decrease in accuracy". 4 EV at full aperture in RAW. 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. Those are two factors that we all can appreciate and these principles are hard at work here. At startup and shutdown, the scene in the viewfinder often bounces noticeably. This amount is just-visible in certain situations, such as a clear blue sky. and allows precise autofocus calibration at four distances for four focal lengths. Four of these are made of special types of glass. " As I could no longer trust my work as being current, I updated to the latest firmware an easy task with the Sigma Dock and spent much of another day re-testing the lens. Reason for poor review: Did not find my model• 26x, and that is not macro, but you can shoot small subjects with it beautifully. 8 x 8. Expect about 2 stops of shading in 100mm corners and about 1. fast usually proves similarly accurate I didn't perceive a difference with this lens and... At about 1 mile 1. There it was. A touch of softness is visible at 100mm, the 200mm result looks great and a bit of softness along with a bit of heat wave influence shows in the 400mm result. 3 DG OS HSM Contemporary Lens Which telephoto lens should I get? The lens focused fine, the OS worked well and the zoom range is extensive. I looked out the studio windows to see some beautiful clouds one of my weaknesses and I saw a great opportunity to put the Sigma 100-400mm OS lens into use. 4x in place. The optical design is complex, with 21 lens elements. Then this little storm came directly at me. However, this lens is likely to garner more attention than many of the predecessors. One corner difference created by stopping down is reduction of vignetting. Smoother AF operation The HSM Hyper Sonic Motor ensures high speed and quiet AF. 7 out of 5 stars 4. The drifting is especially noticeable if the lens is tripod-mounted and I suggest turning OS off when photographing in this manner. These examples are from the center of the frame. However, in the default Standard mode, the image in the viewfinder shows only modest stabilization taking place. As is often the case, the peripheral AF points performed very slightly worse than the center AF point. Consider renting. Here is a comparison table showing minimum focus distance and maximum magnification specs for similar-class lenses. A distance scale is provided in a window and as usual, the scale shows both feet and meter increments. 9 oz 1160g 3. I'll talk more about the Custom switch under the dock subheading below. 0mm 77mm 2013 40. The Sigma Dock allows focus calibration adjustments to be made at 4 focal lengths for 4 focus distances 16 total adjustments. High-precision, durable brass bayonet mount• In low light, this lens tends to hunt for focus a significant amount, but that behavior is not unexpected with a slow telephoto lens. 3 DG OS HSM Contemporary shows a nicely even picture. 3 DG OS HSM Contemporary Lens was online retail-sourced. Remaining are the Canon and Nikon options. Using the dock, two custom modes are available for programming via the dock , including AF speed options of "Fast AF Priority" and "Smooth AF Priority". 55 lbs 1. The 1. 6 stops of shading in longer focal length results. 2" 1200mm 0. raised from the ring. it is only available for 11mm of the focal length range, from 100mm through 111mm. 56 lbs 4. Without wide apertures helping to make fast shutter speeds available, this lens is disadvantaged. While small and light for its class, this is a large, heavy lens to be hanging from a camera mounted to a tripod or monopod and you can expect even a strong tripod and head to sag a bit when locking it down. Classy-appearing is the white backgrounds on the AF and lock switches, visually indicating their set positions. 4 x 7. 5 percent. Overall, this lens performs well in this regard. As I've overstated, I am not a fan of the rather narrow categorization structure. After reading such great reviews for this product, I decided that this would work for me. 2" 108. 45 lbs 2. A modestly-sized. 17 inches 10. When we arrived up the mountain, an inversion layer swept over the area. Your camera will automatically account for the change in auto exposure modes, but making use of the widest-available aperture in manual exposure mode is complicated somewhat. My distraction was worth it and hopefully this tangent will help you see the value in having this focal length range available in your kit. Many of the remaining options are the 150-600mm telephoto zooms included in the above table comparisons. I used the lens in light rain prior to photographing the rainbow and had no issues. 3 DG OS HSM Contemporary has won photographers over with its strong fundamental performance and exceptional image quality. While this lens is currently a "Contemporary" one, it can be used for sports photography and it is at least as well-suited for wildlife and landscape photography, which lack their own categories. I indeed had programmed them properly. And, landscape photography is an excellent opportunity to use this technique. 6" 94. If you can drop down to 300mm on the long end, more options open up, including the and. Using the dock and a custom mode, the autofocus range can be customized as desired. This lens is not an ideal choice for stopping low light action. 43 lbs 2. This lens' 0. 0" 1600mm minimum focus distance, is a big asset to this lens. LENS TELECONVERTER COMPATIBILITY CHART Get more reach with what you have. 2" 1200mm 0. Providing significantly more magnification capability to this lens are teleconverters. Extension tubes are hollow tubes with electronic connections that shift a lens farther from the camera. Wildlife photography is one of the best uses for the 100-400mm focal length range.。 。
