Manual-focus override is by simply turning the dedicated focus ring. When mentioning landscape photography, many immediately think of wide-angle lenses. You expect to get what you ordered, and you want to pay a low price for it. The 70mm focal length result shows a slight focus blur. Test this attribute on your lens before relying on it. all are great uses for the 70-180mm focal lengths. The Tamron also performs fairly well with regards to vignetting, which is surprising given the small front element combined with the fast aperture. How to Update The lens firmware can be updated using cameras that support this lens firmware update. At 70mm, the working distance with the hood installed is a mere 1. I want to touch, briefly, on the subject of durability. The Sony lens has 11 aperture blades vs. 8 Di III VXD is not an image stabilized lens, but ". Created by the neutrally-colored subjects, fringing color differences were introduced by the lens. "Portrait photography" is a broad designation that covers a wide range of potential still and video uses at a wide variety of potential venues, including both indoors home, church, school, etc. 8 GM OSS Lens at 200mm doing the same at 22. The non-rubberized ribbed focus ring is modest in size and raised just enough above the smooth lens barrel to be tactilely easy to locate. 8 Di III zoom lenses set the expectations bar high, and I'm not at all surprised that this third lens has cleared that bar and joined the best-seller list with the other two. 1 with a working distance of 0. Color is pleasing and relatively neutral, fitting in well with the other Tamron zoom lenses. You may consent to the use of cookies or opt out. Both lenses have fluorine-coating on the front element to repel water, dust, and dirt and make cleaning easier. In the 70-135mm range, a minor amount of lateral CA is present. and can go down to a maximum magnification of 1:1. 0 77 2017 For many more comparisons, review the complete using the site's lens specifications tool. Coma clears as the aperture is narrowed. In the examples below, look at the fringing colors in the out of focus specular highlights. See details for additional description. As seen earlier in the review, the amount of blur a lens can produce is easy to show, and telephoto lenses are advantaged in this regard. Improvements This update improves the following issues:. Most modern lenses have lens correction profiles available, and distortion can easily be removed using these. At 180mm, a subject measuring about 5. This lens focuses internally with only subtle clicks and faint buzzing being heard with an ear next to the lens in a quiet environment. 8" 69 x 46mm fills the frame of a full-frame camera. The new Tamron III is much smaller than the Sony at 88 x 198mm 3. 88m 1:10 magnification , which is not very fast and a bit slower than the Sony FE 70-200mm f2. The Sony lens has a noticeably higher price than the Tamron lens, but you do get a case with the Sony lens. Two lens aberrations that are particularly evident when shooting images of stars, mainly because bright points of light against a dark background make them easier to see. This provides unprecedented fast and precise AF performance. The lens performs reasonably well with regards to flare. I have recently purchased this lens and agree with your review. The Tamron's light weight does not exude rugged build quality confidence, but it seems nicely built with tight tolerances, and a very long warranty indicates that Tamron expects the lens to withstand years of normal use. long — but extends when zoomed to 180mm focal length. Overall, an excellent performance with regards to chromatic aberration. The medium-sized 67mm filter threads mean that filters for this lens are not too expensive. In some lens designs, the plane of sharp focus can move forward or backward as a narrower aperture is selected. How close do you have to get for 1:10 magnification e. Tamron's Di III lenses are designed for use on mirrorless interchangeable lens cameras. 8 Di III RXD and the 28-75mm f2. The long edge of the largest stamp measures 1. 8 Di III shares the same small 67mm filter thread with the shorter zooms and it is only 81mm 3. Another great use of telephoto lenses for landscape photography is to focus on closer details, allowing a strong background blur to isolate those within the image. The second set of examples are full images reduced in size, and these appear nice in quality. The lens shows only a little zoom creep but the zoom lock at 70mm can prevent even that. Unlike most 70-200mm lenses available at review time, this lens features an extending design, increasing in length by up to 1. An occasional sharp image was made with exposures as long as 0. Above from left to right: Tamron 17-28mm f2. 8 Di III VXD Lens The same lenses are shown below with their hoods in place. 8 Di III VXD Model A056 for Sony E-mount, full-frame mirrorless cameras, is now available. This lens compared to the other 2 lenses is much lighter and performs just as well. 5x being the angle of view multiplier for Sony's lineup. Note that even modestly-high sharpness settings are destructive to image details and hide the actual characteristics of a lens. By simultaneously operating two VXD units via electronic control, the system produces clear and sharp images. The same test at 70mm focal length produced only a 0. 8 Di III VXD Lens turns in very sharp results throughout the entire focal length range. While this mode makes it difficult to focus around the image periphery,. The effect of different colors of the spectrum being magnified differently is referred to as lateral or transverse CA Chromatic Aberration. Starting AF with the lens in a strongly-defocused state will result in a slower AF experience as the camera searches for the proper distance. Use the hood, and reversed does not count. With no IS switch on the lens, the camera menu is used to enable or disable IBIS, slowing some workflows, such as when going from tripod to handheld. The two images below illustrate the maximum background blur this lens can create. The Tamron lens has slightly narrower filter threads 67mm vs. This reduces the resolution of a 42MP image shot at 180mm to 34MP which is only notable if you look very close. Verified purchase: Yes Condition: New• Sony has worked closely with third-party lens manufacturers, reducing the risk of purchasing such lenses. At mid-distance, the bokeh becomes a bit more nervous, though is still acceptable. I manually focused the lens at 180mm and then slowly zoomed back to 70mm checking focus on the way. Focus and zoom Focus accuracy and repeatability is critical to consistently produce sharp shots. This is a slightly simpler design than the Sony with 23 elements in 18 groups. When mounted on an APS-C imaging sensor format camera body, this lens provides an angle of view similar to a 105-270mm lens on a full-frame body. Also positive is that this is a common filter size, increasing the potential for filter sharing. As the focal length increases, pincushion distortion gradually builds until becoming moderately strong at 180mm, with the corners appearing pulled outward. 8 Di III VXD Lens focuses very accurately and very quickly, though the Sony a7R III and a7R IV's defocus and then focus behavior in single-shot focusing mode slows down the realized lock time. 8 Di III which is very convenient — and saves costs. 8, and will fit the bill for all but the pickiest shooters. Axial CA remains at least somewhat persistent when stopping down with the color misalignment effect increasing with defocusing. Cityscapes are essentially landscape images with cities in them, and this focal length range is often a great choice for more-distant city views. These images typically include the animal at least nearly filling the frame, and for that task, this focal length range often falls short of the need. and outdoors yard, beach, park, parade, playground, etc. 8, move in close to your subject, and watch the distracting background melt away. In this case, that range is fully covered by very compact high-performing lenses. 70mm: 180mm: A focus distance window is not provided on the lens, but a focus distance meter shows in the lower portion of the camera's electronic viewfinder during manual focusing. Videos captured at standard wide-aspect ratios also avoid the use of corners. The hood bayonet-mounts and though lacking a release button, is not difficult to install or remove. There is some color difference at 70mm, but it is not strong. Any color misalignment present can easily be seen in the site's image quality tool, but let's also look at a set of worst-case examples. 85m throughout the focus range, allowing for a maximum magnification of 1:4. FTM Full Time Manual focusing is supported in Sony's DMF Direct Manual Focus mode with the shutter release half-pressed, or the AF-ON button is pressed. The zoom ring is positioned in front of the focus ring, and as usual for similar designs, the zoom ring is forward of the balance point. In the portrait range, bokeh is smooth with fairly evenly rendered specular highlights and a very pleasing look. With a 9-blade count aperture, point light sources captured with a narrow aperture setting and showing a sunstar effect will have 18 points. Tamron and Sony do not manufacture extension tubes at review time, but are available. The front lens element features protective water- and oil-repelling fluorine coating. The minimum focus distance is measured from the imaging sensor plane with the balance of the camera, lens, and lens hood length taking their space out of the number to create the working distance. Telephoto focal lengths can create excellent landscape images, especially when there is a distant subject to be emphasized, rendered significant in the frame, such as a mountain. With the right lens profile and software, lateral CA is often easily correctable often in the camera by radially shifting the colors to coincide. The other difference is the strength of the background blur that is created with the longer focal length able to create a slightly stronger blur. Coma occurs when light rays from a point of light spread out from that point, instead of being refocused as a point on the sensor. People are also frequently photographed participating in sporting and other action scenarios using this focal length range. The three aspherical elements, including both glass-molded and hybrid types, are designed to reduce spherical aberrations and distortion. These mid-telephoto focal lengths naturally push the focus distances far enough away to avoid perspective distortion, including noses appearing too large relative to the rest of the face and ears, yet not so far that communication with the subject becomes difficult. I very much like the quality of your reviews and find them to be reliable. That this focal length range and aperture combination is incredibly useful means I often choose a 70-200 lens for my needs. Still, distortion correction is destructive at the pixel level as some portion of the image must be stretched, or the overall dimensions reduced. Overall, this lens turns in outstanding optical performance. I switched from Canon to Nikon and now to Sony and i've owned their 70-200 lenses for many years. At this point in a review, I always provide a disclaimer regarding potential compatibility issues with third-party lenses. Flare and ghosting are caused by bright light reflecting off of the surfaces of lens elements, resulting in reduced contrast and sometimes-interesting artifacts. Use the site's to create additional comparisons. for a very tightly cropped head-shot? Alternatively get yourself a copy of my or Thanks! [0] The Tamron III comes without a pouch but the lens hood is included and reversible for transport. For more information see my -so-far. 8, like most modern lenses, shows strong contrast and good color saturation throughout the aperture range. The uses for this angle of view are similar, with more working distance required for the longer focal lengths. It is up to you to determine if this difference matters. From a size and weight perspective, this lens is practically in a class of its own. Firmware version Ver. For portraits, a blurred background is often desired, and the corners are often not in focus. 8 Di III has 19 elements in 14 groups including 6 special dispersion elements and 3 aspherical elements. Again, we are seeing very good performance from this lens. Having a menu option required for this commonly-used feature sometimes slows the workflow. 8 remains the narrowest aperture I want to use when photographing many indoor activities. When you use flashes, there is a delay from the time the shutter button is pressed to the time the shutter and the flash release. At 180mm focal length the lens focuses in around 0. while the Sony has a longer reach of 2. The Tamron G2 is 88 x 191mm 3. The other wide aperture disadvantage one can count on is increased price over similar focal length range lenses with narrower apertures. Schedule your rental now: Using these links for your rental. The left hand rests under the focus ring during comfortable use, and the right hand is called on to help support the camera when the left hand is positioned for comfortable zoom ring use. Except for a small number of specialty lenses, the wide aperture bokeh in the corner of the frame does not produce round defocused highlights with these effects taking on a cat's eye shape due to a form of mechanical vignetting. Using the most extreme minimum focus distance results in poor periphery image quality at 70mm, but using longer focus distances simply brings this lens in line with the rest of the class in this regard, leaving, minimally, it not disadvantaged. Something is not adding up — and this is not the first time Tamron has created this equation. When rever, the narrow diameter hood stays compact. Tamron warned that the periphery of the image would not be in focus at the 70mm minimum focus distance, and they are correct. Inquiries regarding this matter Please contact your local Tamron distributor. 180mm: The extreme corner image quality this lens is producing is outstanding except for the wide-open 180mm results. my preference, it is a perfect design for making the focus ring easy to use, especially when using the lens handheld where the focus ring is at the fingertips of the hand balancing the lens. At 180mm focal length maximum magnification is still a very useful 1:4. " [Tamron USA website] While this lens is not stabilized, Sony generally takes care of that omission with Steady Shot or IBIS In-Body Image Stabilization. Corner sharpness does not always matter. However, do not expect corner-to-corner sharp images at this magnification. The lens is very sharp, with pleasing bokeh, good color and contrast and minimal aberrations. The Sony and the Tamron G2 take 77mm filters. The effect is more substantial at 180mm, but this amount is still relatively low for a max focal length extent on a zoom lens. 8 zoom is as a general portrait or event zoom, bokeh is fairly important with such a lens. The Sony lens has modestly less geometric distortion. Contents• 8 Di III VXD Lens for only a short period of time? 8 Di III VXD Lens design, illustrated above, features six low dispersion elements, including both XLD eXtra Low Dispersion and LD Low Dispersion elements for reduced color fringing and chromatic aberrations, improving clarity and color accuracy. In addition to stopping action in low light, the wide aperture invites handholding the camera in much lower light levels. It may not have all the bells and whistles of Sony's professional zoom lens and its biggest disadvantage is the incompatibility with teleconverters. Size diameter x length : 81 x 149mm 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. However, the lens also has a special close focus mode that can be enabled by switching the lens into manual focus. 8, this lens shows a very mild about-1. The Sony has linear gearing with a turn of 100 degrees, the Tamron G2 turns 130 degrees and has the added benefit of a distance- and dof-scale. Dear users and potential purchasers of Tamron products. The Sony lens's compatibility with teleconverters makes a significant difference. Factor in the compact, lightweight, modern lens design and the spirit of mirrorless interchangeable lens cameras is encompassed and exceeded. Shooting things like the sun can lead to a haze and loss of contrast emanating from the light source, along with some purple and green color flare around the light source. 6 with manual focus at 200mm focal length and 0. The rubberized focus ring is substantial in size, and covering a large percentage of the lens barrel, this ring is easy to find. This effect is called focus shift residual spherical aberration or RSA , it is seldom never? This lens has exactly 0 buttons and one switch, the zoom lock switch. 9, has OSS, and has an array of switches available. Tamron USA provides a significant 6-year limited warranty, and Tamron Europe's limited warranty is an also-long five years. 8 Di III shares the same 67mm filter-thread with its shorter siblings the 17-28mm f2. The Sony has a nicely padded lens case plus strap and a tripod-collar. "The greatest feature of the series is the excellent portability. The makes an interesting comparison with the Tamron lens. 0x teleconverter with the Tamron III. 6, the shading decreases to about-0. Summary The lens comparisons just shared create that awkward feeling. One-stop of shading is the amount often used as the visibility number, though subject details provide a widely-varying amount of vignetting discernibility. Tight tolerances on moving parts add some assurance that this lens has been carefully designed and that modern construction methods were utilized. This ring is very smooth and has an ideal amount of resistance with no play. 8 is achieved at 70mm focal length albeit with a very short working distance of 9cm lens hood detached. This is a 3 stop advantage from the sensor-based image stabilization built into the Sony A7R II camera at 180mm focal length — which probably becomes even better at shorter focal lengths. As I've been saying in the other recent Sony-mount Tamron lens reviews, I rarely suggest buying a camera brand specifically to enable the use of a lens from a different manufacturer. These results do not show pin-point perfect stars, but they are not bad from a relative standpoint. I have also noticed the autofocus issues you mention when in single shot mode. Optics: The Tamron 70-180mm f2. Very significant is the price disparity — greater than even the weight difference. Stopping down a stop or two brings those edges also into outstanding territory. 6" 92mm working distance may impact subject lighting. Increased size and weight accompany this attribute. 5-stops at 180mm, a noticeable but not comparatively bad amount. This will allow for very nice closeup capabilities for flowers or other smaller details. Even these results are very good until the extreme corner, and stopping down improves these corners. Looking at the specs and measurements, the shows the two lenses, despite the significant full-stop aperture opening difference, having similar weights and the Tamron lens having smaller dimensions, including at full extension. This looks like a pretty high price for a lens without optical stabilization and only 180mm maximum focal length. 8 telephoto zoom lens in my hand, this is the one I would want. AF-operation of the new lens and image stabilization of the A7R II is inaudible from the outside and if you record video with the built-in microphone the AF-drive produces no noise. Assessing the quality is more challenging due in part to the infinite number of variables present in all available scenes. 8 aperture mandatory, those capturing portraits or photographing low light events, including sporting events, will appreciate the faster shutter speeds and lower ISO settings made possible by the additional light reaching their imaging sensors. This strong, attractive, semi-rigid plastic hood is relatively large, providing protection from impact and flare-inducing bright lights. Edges and corners are a little less crisp, but are still very good wide open. Be sure to find details in the plane of sharp focus to base your opinions. This lens features a "Moisture-Resistant Construction," including a mount gasket. In general, the more a lens is stopped down, the larger and better-shaped the sunstars tend to be, with wide aperture lenses usually having an advantage in this regard. You are going to want this lens. Great is that Tamron always includes the lens hood in the box with this lens model getting the HA056 lens hood logically adding an "H" for hood to the front of the lens's model number "A056". Those moving to mirrorless lenses to gain the small size and lighter weight should take notice. " for more details• The lens is a typical design for professional users offering optical image stabilization with two modes, a focus-lock button, focus limiter, and a detachable tripod foot. Therefore, the viewfinder image is very obviously stabilized, and sensor-based AF takes advantage of the stabilized view for improved accuracy. 67m working distance between front lens and object. Study the pattern showing in our vignetting test tool to determine how your images will be affected. Special-purpose lenses are available to create such an effect, so this look is not without usefulness. 8 and eases when stopping down. If you are taking pictures of people, this lens has your name on it. Sony has the FE 70-200mm f2. Please review the information below. 8 zooms is typically very high. 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. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Those warranty durations should help alleviate any build quality concerns. The Tamron G2 has 23 elements in 17 groups and does not employ fluorine-coating. You get a case with the Sony lens. The Tamron G2 is similar to the Sony except that it has no focus hold buttons. 8 with manual focus at 70mm focal length. While this design is seldom never? These combine to create a less sharp, hazy-appearing image quality at the widest apertures. As I mentioned earlier in this review, there is a difference between the 180mm and 200mm focal lengths. It is not hard to use this lens exclusively for portrait shoots. Low light levels always challenge AF performance, but this lens on a Sony a7R IV focuses on a subject with reasonable contrast in very dark conditions. The Tamron G2 comes with a soft pouch and a removable tripod-collar that has an Arca-Swiss style tripod interface. The firmware update is available through Sony E-mount camera bodies. Removal is sometimes very challenging, and in some cases, flare effects can be quite destructive to image quality. When I adjusted the focus from infinity to 1. 6 oz 669g lighter weight, the 14. Street photography, usually done in cities, is another excellent use for the 70-180mm range.。 。
