8 shows mild pincushion distortion at 70mm that worsens as you zoom towards 180mm. The following samples illustrate this lens's maximum magnification capabilities. and can go down to a maximum magnification of 1:1. 8 Di III look like a well rounded design. How good is the detail around the eyes? 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. all are great uses for the 70-180mm focal lengths. The effect is more substantial at 180mm, but this amount is still relatively low for a max focal length extent on a zoom lens. What are the disadvantages of a wide aperture? 9, has OSS, and has an array of switches available. 67m working distance between front lens and object. Note that even modestly-high sharpness settings are destructive to image details and hide the actual characteristics of a lens. 8 Di III VXD Lens turns in very sharp results throughout the entire focal length range. Most modern lenses have lens correction profiles available, and distortion can easily be removed using these. This lens invites subject framing ranging from full-body portraits at 70mm to tight headshots at 180mm. at 70mm focal length with manual focus and 0. The Sony lens has OSS and has an array of switches available. 8 GM does render more smoothly in these mid-distance situations. 8 Di III shares the same 67mm filter-thread with its shorter siblings the 17-28mm f2. plus 46mm for the lens hood 94mm diameter. I have recently purchased this lens and agree with your review. " [Tamron USA] Tamron stopped short of the full to-200mm focal length range, but they provided a considerably smaller and lighter lens that, in keeping with the other Tamron Di III lenses to date, delivers outstanding image quality at a very attractive price. However, the lens also has a special close focus mode that can be enabled by switching the lens into manual focus. Tamron warned that the periphery of the image would not be in focus at the 70mm minimum focus distance, and they are correct. 8 Di III Sony-mount lenses produce very impressively sharp images at their widest aperture, and we should not be surprised to see this one live up to that established level of expectation. The Sony has a nicely padded lens case plus strap and a tripod-collar. When the lens is powered down the focus group inside the lens slides back and forth freely as the focus drive is not engaged. This effect is called focus shift residual spherical aberration or RSA , it is seldom never? 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. 8 Di III VXD Lens to other lenses. 8 Di III VXD is not an image stabilized lens, but ". The firmware update is available through Sony E-mount camera bodies. 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. Optics: The Tamron 70-180mm f2. Sigma offers the stabilized Sigma 70-200mm f2. 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.

You get a case with the Sony lens. When mentioning landscape photography, many immediately think of wide-angle lenses. 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. At 180mm, a subject measuring about 5. This lens shows a moderate change in subject size as full extent focus adjustments are made. while the Sony has a longer reach of 2. Price, Value, Wrap Up While not a cheap lens, the 70-180 VXD is comparatively inexpensive. That makes a low thunking sound and you can feel the focus group moving around. 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 lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. 8 Di III VXD review• While the 180mm focal length may be modestly too wide for large field sports photography, it works very well for closer action such as that found at track and field meets and on the basketball court. 8 Di III zoom lenses covering the most-needed focal length range. 1 does not recognize the profile completely: vignette is compensated as it was set in camera but you cannot switch between off and auto in post-processing while CA-compensation is always ON, distortion compensation always OFF. Two tele-photo zoom lenses for E-mount 8 GM OSS coverage on Sony A7R II FF body at 70mm left and 200mm right , Distortion Compensation ON Should you worry about the missing 20mm on the long end of the new Tamron?

There is often adequate space in even a small studio for portraiture with the focal length range provided by this lens. At 180mm focal length the lens focuses in around 0. 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. Therefore, the viewfinder image is very obviously stabilized, and sensor-based AF takes advantage of the stabilized view for improved accuracy. The lens' other functions,- the speed of the auto focusing is every bit as good as the SONY equivalent. 8 remains the narrowest aperture I want to use when photographing many indoor activities. There should be only black and white colors in these images, and the additional colors are showing the presence of lateral CA. It earned a Highly Recommended in my. It is up to you to determine if this difference matters. Unless the wildlife subject is very large or very close, the longest focal length in this lens will usually be found too short for this task without cropping. 180mm: The extreme corner image quality this lens is producing is outstanding except for the wide-open 180mm results. The second set of examples are full images reduced in size, and these appear nice in quality. Both lenses have fluorine-coating on the front element to repel water, dust, and dirt and make cleaning easier. Remember that lateral CA is another aberration apparent in the corners. Unlike most 70-200mm lenses available at review time, this lens features an extending design, increasing in length by up to 1. Also positive is that this is a common filter size, increasing the potential for filter sharing. Need a shorter minimum focus distance and greater magnification? Yes, this lens is "good value". This will allow for very nice closeup capabilities for flowers or other smaller details. How to Update The lens firmware can be updated using cameras that support this lens firmware update. The Tamron G2 has 23 elements in 17 groups and does not employ fluorine-coating. See details for additional description. " [Tamron USA website] You likely gleaned from those lines that this lens focuses closer in MF mode than in AF mode. Tamron and Sony do not manufacture extension tubes at review time, but are available. The Sony lens's compatibility with teleconverters is a significant difference. The Tamron 70-180 VXD is another lens that encourages this scenario. Image stabilization is especially helpful with telephoto focal lengths, and these lenses usually have stabilization built in. Corner sharpness does not always matter. The Tamron G2 also offers optical stabilization. It produces very good image quality including a soft Bokeh and very usable close-up performance in a package that is much smaller, lighter, and cheaper than Sony's FE 70-200mm f2. 8 is shooting in the close-up range down to 0. 8, like most modern lenses, shows strong contrast and good color saturation throughout the aperture range. It is not hard to use this lens exclusively for portrait shoots. Overall, an excellent performance with regards to chromatic aberration. In the 70-135mm range, a minor amount of lateral CA is present. 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. A very good maximum magnification of 1:1. " for more details• Zooming the Tamron III to 180mm focal length extends the lens by 29mm which is still shorter than the Sony which does not change its length during zooming. 5x being the angle of view multiplier for Sony's lineup. 8 Di III VXD Lens The same lenses are shown below with their hoods in place. That this focal length range and aperture combination is incredibly useful means I often choose a 70-200 lens for my needs. While the first joint on my right hand's middle finger still impacts the lens body, becoming red and slightly sore when holding this lens in shooting position for relatively long periods, the relatively narrow lens body means that the pressure is not as bad as with some lenses. The three aspherical elements, including both glass-molded and hybrid types, are designed to reduce spherical aberrations and distortion. An extension tube mounted behind this lens should provide some improvement, but these will primarily be useful at the longer focal lengths where there is physically room for improvement. At 180mm focal length maximum magnification is still a very useful 1:4. The hood bayonet-mounts and though lacking a release button, is not difficult to install or remove. The Tamron 70-180mm produces image sharpness right up there with the very best from other manufacturers. These combine to create a less sharp, hazy-appearing image quality at the widest apertures. 8 Di III VXD Model A056 for Sony E-mount, full-frame mirrorless cameras, is now available. With a 9-blade count aperture, point light sources captured with a narrow aperture setting and showing a sunstar effect will have 18 points.

In the example above, look at the fringing colors in out of focus areas with specular highlights in the foreground showing different colors than those in the background. The lens is very sharp, with pleasing bokeh, good color and contrast and minimal aberrations. 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. Thus, I was anxious to determine how well IBIS worked with such a lens. 25x , though its full magnification image quality is compromised. Contents• 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. Videos captured at standard wide-aspect ratios also avoid the use of corners. The long edge of the largest stamp measures 1. 8, this lens shows minor flare effects.

Please review the information below. By simultaneously operating two VXD units via electronic control, the system produces clear and sharp images. The rubberized focus ring is substantial in size, and covering a large percentage of the lens barrel, this ring is easy to find. As the focal length increases, pincushion distortion gradually builds until becoming moderately strong at 180mm, with the corners appearing pulled outward. 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. 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. In the examples below, look at the fringing colors in the out of focus specular highlights. This is a slightly simpler design than the Sony with 23 elements in 18 groups. 8 is achieved at 70mm focal length albeit with a very short working distance of 9cm lens hood detached. 8 helps your subject really pop out of the background, as evidenced in the photo of the tree above. That the firmware for this lens can easily be updated through compatible cameras further reduces risk. 5-stops at 180mm, a noticeable but not comparatively bad amount. This strong, attractive, semi-rigid plastic hood is relatively large, providing protection from impact and flare-inducing bright lights. 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 scenario begs for some hidden catch, but. 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. These results do not show pin-point perfect stars, but they are not bad from a relative standpoint. 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. The , and 70-180 combined fully cover the popular 17-180mm focal length range. In some lens designs, the plane of sharp focus can move forward or backward as a narrower aperture is selected. "The greatest feature of the series is the excellent portability. 8 Di III is listed at 1499 EUR incl. You expect to get what you ordered, and you want to pay a low price for it. When focusing closer to infinity, the lens is just slightly softer than in the close to mid-distance range, but detail is still very good, and the lens is perfectly usable for landscape use, even on high-megapixel bodies. The Tamron G2 is 88 x 191mm 3. But opting out of some of these cookies may affect your browsing experience. I often complain about the lack of finger space Sony provided between the lens and grip in their review-time-current mirrorless cameras, including the. This focal length range is great for photographing pets, including dogs and cats. 8 Di III shares the same small 67mm filter thread with the shorter zooms and it is only 81mm 3. The two images below illustrate the maximum background blur this lens can create.

The Sony lens has 11 aperture blades vs. 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. How close do you have to get for 1:10 magnification e. 8 and eases when stopping down. Expect the lens hood to strongly shade the subject at this distance, and even with hood removed, the still-close 3. 8 aperture, Tamron selected the focal length of 180mm at the telephoto end and employed an innovative zoom mechanism. Next check out my quality results! [0] Auto focus: Yes with built-in AF drive. I am very happy with my purchase and now have the three Tamron 2. When I adjusted the focus from infinity to 1. 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. Flare effects can be embraced or avoided, or removal can be attempted. 8 Di III VXD Lens delivering image quality comparable to or surpassing the best-in-class lenses. and outdoors yard, beach, park, parade, playground, etc. Vignetting is correctable 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 significant percentage of the product images on this site were captured within this focal length range, and this range works well for more substantial products, including vehicles.
