Tamron 28-200mm F/2.8-5.6 Di III RXD review

  Photographic equipment should not be classified very carefully, but after all, each product has its own unique characteristics, so if such equipment is subdivided, there is such a category of products, which is characterized by a wide zoom ratio The famous name is the “donkey head” commonly known by movie friends.

   On June 11, 2020, Tamron officially released the seventh full-frame lens of Sony E mount: 28-200mmF2.8-5.6DiIIIRXD. The birth of this lens allows Sony users to There is one more option on the selection.

   to know about Tamron Large zoom is very historical. Tamron released the first large zoom lens in 1992 with a focal length of 28-200mm: AF28-200mmF3.8-5.6Aspherical, and this lens also won the 1993-1994 EISA Award . After a lapse of 28 years, the Tamron still chose the focal length of 28-200mm for the large zoom of the E-mount. I don’t know if it contains some special meaning, perhaps it is a tribute to the first large zoom, or perhaps it is 28-200 is the beginning of Tamron’s large zoom, and on the E-mount large zoom lens, Tamron’s large zoom is also a new beginning.

  Understanding these backgrounds, it is not difficult to discover why Tamron released the 28-200mmF2.8-5.6DiIIIRXD lens. As an E-mount lens, especially a large zoom lens, although Tamron was launched for the first time, users can easily think of the Sony FE24-240mmF3.5-6.3OSS lens when they see such a focal length, so I will simply do it here. A comparison is made.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   You can see Tamron 28-200mmF2.8-5.6DiIIIRXD The size of the fuselage is almost the same as that of the Sony FE24-240mmF3.5-6.3OSS lens. The Tamron is slightly smaller. Although the focal length is less wide-angle and less telephoto, the aperture is expanded to F/2.8. Many people will ask how to choose these two lenses. After reading the simple parameter comparison above, it depends on what you need?

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   This 28-200mmF2.8-5.6DiIIIRXD lens of Tamron is still Very interesting, this is the first large zoom lens in Tamron’s full-frame micro-single lens group, and it is also the first large zoom lens to achieve f/2.8 at 28mm, and this lens still continues Tamron’s usual lightweight The design is very compact, but it should be noted that this lens does not have an anti-shake function. Fortunately, all Sony mirrorless cameras are equipped with body anti-shake. Next, I will break apart the characteristics of this lens, and perhaps give you a relatively comprehensive understanding of this lens.

  1. Excellent image quality performance

   Tamron 28-200mmF2.8-5.6DiIIIRXD uses a number of special lenses, including 2 GM glass cast aspheric lenses, 2 conforming aspheric lenses, and 1 XLD Super low-dispersion lens and 2 LD low-dispersion lenses, so many special lenses are actually added to effectively suppress various chromatic aberrations and improve picture quality.

Tamron 28-200mm F/2.8-5.6 Di III RXD reviewTamron 28-200mm F/2.8-5.6 Di III RXD review

  Tenglong’s official information mentioned that the aspheric lens can maintain the high resolution of the center and edge of the picture, while the low dispersion lens can effectively suppress the dispersion, and this The lens supports the correction function built into the camera. Regarding the image quality, we have a more intuitive and detailed test in the video. In fact, based on the performance of several Tamron E-mount full-frame lenses before, I believe everyone has a good idea!

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   But from the official MTF curve, it can still be seen The imaging performance of Tamron 28-200mmF2.8-5.6DiIIIRXD. First of all, at the 28mm end, the MTF of 10 lines/mm is basically above 0.8, and when matched with an APS-C format camera, the MTF can reach above 0.9, so in terms of permeability, this lens performs quite well; The MTF performance of 30 lines/mm is also above 0.5 at the edge, while the center is above 0.9, so the sharpness performance at 28mm is quite good; and at the 200mm end, it can be found that the overall performance of this lens is better than 28mm . And this is only the test data on paper, please see the video and samples for the actual situation.

  2. The maximum aperture of each focal length

   Tamron’s large zoom lens is actually very historical, and now the Tamron large zoom lens has been greatly improved in quality. This time, the Tamron 28-200mmF2.8-5.6DiIIIRXD has 7 It’s not easy to achieve a configuration such as 28mmf/2.8 for the first time with multiple zooming capabilities. As the focal length changes, the aperture value will also change. After all, it is unrealistic to make such a focal length a constant aperture.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   and I sent Tamron 28-200mmF2.8-5.6DiIIIRXD before In spy photos, many people worry that Tamron’s aperture will shrink quickly after 28mm focal length, but is this really the case? This lens can achieve f/3.5 aperture value at 50mm; f/4.5 at 100mm, maximum f/5.6 aperture at 150mm, 200mm is also f/5.6 configuration, it can be said that the practicality is still Very large, and with the combination of different focal lengths and apertures, with excellent close-up performance, I think it can meet the needs of most users!

  3. Family-style design

   In fact, Tamron 28-200mmF2.8-5.6DiIIIRXD uses an external zoom design. The overall design language is exactly the same as the previous Tamron E-mount full-frame lens, with a large zoom ring , The overall design is more low-key, elegant and tasteful.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   The barrel of this lens is not long, but the barrel The bottom part is equipped with the unique “Golden Gold” color metal decorative ring of Tamron’s new lens, so it feels very similar to the previous 17-28mmF/2.8DiIIIRXD, 28-75mmF/2.8DiIIIRXD and 70-180mmF/2.8DiIIIVXD . However, because this lens does not have the anti-shake function, on the lens body switch, this lens only has a zoom lock lever, which can ensure that it will not protrude when carrying the lens.

  4.RXD drive motor

   Actually See what motor the lens uses, you can see from the full name of the lens, Tamron 28-200mmF2.8-5.6DiIIIRXD uses RXD drive motor, the so-called RXD refers to RapidXtra-silentsteppingDrive high-speed ultra-quiet stepping motor. The drive motors of the previous 17-28mmF/2.8DiIIIRXD and 28-75mmF/2.8DiIIIRXD are the same, so in terms of focusing speed, the actual performance of this lens should be quite good. In addition, Tamron’s RXD motor has another advantage. It is quiet, especially when shooting video.

  5. Uniform 67mm caliber

   A seemingly ordinary but not ordinary design, that is, Tamron 28-200mmF2.8-5.6DiIIIRXD still uses 67mm filter diameter this time, but Tamron released earlier The six E-mount full-frame lenses also have a 67mm filter aperture, so it is not difficult to find that this new Tamron lens not only maintains a family-style unified design style in terms of exterior design, but even the filter aperture is the same. To a certain extent, greatly reduce the use cost of filter accessories such as ND filter and PL filter. The front lens cover can also be used in general, so there is no need to spend time looking for lens covers with different calibers when changing lenses.

  6. Excellent close-up ability

   Although Tamron 28-200mmF2.8-5.6DiIIIRXD is a large zoom lens with 7.1x zoom capability, it still has excellent close-up capabilities. The wide-angle end of 28mm is recently The shooting distance is 0.19m, the maximum shooting magnification is 1:3.1, the closest shooting distance at the telephoto end 200mm is 0.8m, and the maximum shooting magnification is 1:3.8. However, it seems that Tamron E-mount lenses all have a close-up function. If you don’t believe you can enjoy the six E-mount full-frame lenses released by Tamron.

  7. Tamron’s ancestral coating

   Tamron’s coating technology is obvious to all. There is even a rumor that the best coating technology in the world is Zeiss, Pentax and Tamron. Although I cannot verify the authenticity of this sentence, There is no way to verify who said this sentence, but there is no reason for it. Everyone should just listen to it like this.

Tamron 28-200mm F/2.8-5.6 Di III RXD reviewTamron 28-200mm F/2.8-5.6 Di III RXD review

  Tenglong 28-200mmF2.8-5.6DiIIIRXD still uses BBAR broadband anti-reflection coating this time, which can reduce glare and ghost reflection to a certain extent , It has a real help to improve the image quality; in addition, this lens also has an anti-fouling coating. Simply put, with this coating, the water droplets and fingerprints on the front lens group can be easily handled.

  8. Tamron full-frame E-mount lens options

   Tamron 28-200mmF2.8-5.6DiIIIRXD is Tamron’s seventh E-mount full-frame lens, with 17-28mmF/2.8DiIIIRXD, 28 -75mmF/2.8DiIIIRXD, 70-180mmF/2.8DiIIIVXD, 20mmF/2.8DiIIIOSDM1: 2, 24mmF/2.8DiIIIOSDM1: 2, 35mmF/2.8DiIIIOSDM1: 2 these six lenses, so for Sony full-frame users, Tamron is not so A complete lens group can be selected, but at least these seven lenses provide a relatively reasonable choice.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

  For example, you can choose 17-28mmF/2.8DiIIIRXD with 28- For a combination of 200mmF2.8-5.6DiIIIRXD to go out, you can also choose 20mmF/2.8DiIIIOSDM1: 2, 24mmF/2.8DiIIIOSDM1: 2, 35mmF/2.8DiIIIOSDM1: 2 with 28-200mmF2.8-5.6DiIIIRXD to go out, anyway, the overall weight is very high Of lightness.

  9. Next, we invited photographer @教摄影的纳纳酱 to bring a series of hands-on experience.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   Everyone thinks that you need to use a large-aperture prime lens for portraits. In fact, sometimes the aperture of 2.8 is also sufficient, for example, we go to match some environmental scenes to realize the picture. The wide angle of this lens is 28mm. We can take a photo with longer legs, use the wide angle, and let the model put her feet forward.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   Take another picture with a telephoto, like this long The focal length is very suitable for shooting such a deep picture, and the space compression is very comfortable.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   I usually like to use the 50mm focal length for portraits. At the focal length, Tamron’s 28-200 can use a 3.5 aperture size, which is definitely sufficient for shooting such environment portraits.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   Just now I challenged a large zoom lens to take portraits. Next Let’s try this lens to shoot scenery again, first try a wide-angle scene, the sharpness is good, and the vignetting is almost invisible.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   In fact, sometimes we are willing to shoot scenery when we see a clear sky. But you don’t want to shoot this kind of cloudy or cloudy day. That’s because you only want to shoot large scenes with a wide angle. In fact, sometimes we use a telephoto to hang a small scene in the distance, so that the weather is not afraid of a little bit. , The picture quality at the longest focal length of 200mm is also very good.

Tamron 28-200mm F/2.8-5.6 Di III RXD review

   When we shoot scenery with 28-200 lens, we can try our best Use different focal lengths to try to compose the picture more, so as to give full play to the characteristics of the lens and make the most of the lens in your hand. Regarding this lens, everyone has seen the actual shooting effect. This large zoom lens covers a very wide range of focal lengths. It is capable of shooting many subjects. With a maximum aperture of 2.8 and excellent image quality performance, I believe it will become A very good helper on your photography journey.

  Editor’s point of view:

  oGhost and flare control is very good, try to avoid the extreme of direct sun entering the lens Phenomenon;

  o The sharpness of the image quality at the center of the entire focal length is excellent. The image quality at the edge of the maximum aperture of the 28mm focal length is softer. The aperture can be improved by one or two stops. The image quality can be reduced after the f/8 aperture. It’s within the control range, so it’s okay to use a small aperture to shoot scenery, the lens can feed the high-pixel camera body;

  o don’t worry too much about the anti-shake problem, after all, the camera has anti-shake , But don’t compare it with a lens with anti-shake, just think about it with your toes to know the result;

  o The close-up ability impressed me very deeply, although it can’t be used as a macro lens, but Ultra-close shots can still give you a good sense of experience;

  o It’s impossible for a lens with a focal length like this to have no dispersion, but everyone’s standards for judging the dispersion of dispersion are different. I think this lens! Row!

  o The focusing speed at the telephoto end is actually not much different from my actual shooting at different focal lengths, and is not much different from the focusing speed of the original E-mount lens; the focusing accuracy of AFC cannot be said to be true. , And the original lens can’t do it!

  The safety shutter at the 200mm end really differs from person to person. Even with anti-shake, some people surpass the safety shutter to shoot successfully, and some people shoot at a lower gear. This really pays attention to a touch;

p>

  o Distortion is definitely there, but it can be described as slight, and it is also easily corrected in the later stage;

  o The overall weight is very light, especially when the camera is taken away after a day of shooting At this time, the weight can determine whether it is portable or not;

   Finally, the price. Tamron’s official pre-sale price is 5490 yuan.
