   As a new mirrorless lens with large zoom ratio, Tamron The 28-200mm F/2.8-5.6 Di III RXD has excellent portability and consistency with the control logic of the series of lenses. The lens achieves an effective combination of large zoom ratio, large aperture and portability. This undoubtedly makes this new lens particularly attractive.

  Image quality

   The new 28-200mm F/2.8-5.6 Di III RXD lens not only has a large zoom ratio, but also has the largest lens aperture at the same focal length. Naturally, the optical performance of the new lens will also attract everyone’s attention. Tamron is quite unpredictable on this lens. The new lens uses a variety of lenses including LD low-dispersion lenses, XLD super-low-dispersion lenses and GM glass cast aspheric lenses. So what is the actual performance of this new lens with a large zoom ratio? Let’s take a look at it through real shots.

  Resolution and sharpness performance

   Let’s take a look at the resolution and sharpness performance of the lens first. In the test, we used a 42.5 million pixel Alpha 7R III body. Let’s take a look at the performance of the lens at the telephoto end of 28mm, 70mm and 200mm respectively.

  First is the 28mm end

   although Large zoom ratio lens, but the quality of this Tamron 28-200mm F/2.8-5.6 Di III RXD lens at the wide-angle end at F2.8 is still very good. The performance of the center imaging area of ​​the lens is quite good at full F2.8, and the edge imaging performance is also better than expected. As the aperture shrinks, the resolution and sharpness of the lens will be further improved. The range from F5.6 to F8.0 is the best image quality area at the wide-angle end, and the quality of the lens is also good at small apertures, which can well meet the requirements of landscape shooting.

  70mm end

   is 70mm end, The maximum aperture of the lens has changed to F4.0. Under F4.0, the center quality performance is still good, while the edge imaging quality has been further improved. Also as the aperture shrinks, the lens quality will be further enhanced. Around F8.0 is the best image quality performance of the lens at 70mm.

   at the telephoto end of 200mm

At the 200mm end, the lens performed quite well at F5.6, with good contrast and sharpness. The edge imaging has also maintained a high level. After the aperture is contracted, the sharpness and resolution will be further improved.

   Generally speaking, as a lens with a large zoom ratio and a lens filter diameter of only 67mm, the resolution and sharpness performance of the Tamron 28-200mm F/2.8-5.6 Di III RXD is still commendable , The good detail performance ensures that the lens can still bring good picture quality performance when matched with a high-pixel body. This is indeed what everyone likes to see.

  dispersion control

   Although it is a large zoom ratio lens, the Tamron 28-200mm F/2.8-5.6 Di III RXD has a large aperture of F2.8-5.6, so the lens Dispersion control is also important. Here we also take a look at the dispersion control performance of the lens.

   At the 28mm end, we took the real shot effects of the lens in high-contrast environments at F2.8 and F8.0 respectively. It can be seen from the 100% enlarged photo that the lens already has a good dispersion suppression ability at full aperture. The purple fringing and green fringing are very slight, the overall control performance is already very good, and after shrinking to a small aperture, the dispersion problem basically disappears.

  200mm end, the dispersion of the lens will be slightly more obvious, but the overall dispersion is not prominent, there are some blue and yellow edges, which is very convenient in later stage Dealt with.

  distortion vignetting

   In terms of distortion control, the lens has a certain degree of barrel distortion at the 70mm end and a certain pincushion distortion at the 180mm end. The lens distortion is not obvious, it is easy to carry out post-processing. This phenomenon can be solved well by turning on the in-camera calibration or through Adobe software later.

   At the 200mm end, the vignetting is significantly reduced. When F5.6 is fully open, there is no obvious vignetting. After reducing the 2 stop aperture to F11, the dark corners of the picture basically disappeared completely.

   As a lens with 28-200mm focal length coverage and a maximum aperture of F2.8-F5.6, Tamron 28-200mm F/2.8-5.6 Di III RXD’s vignetting control is already Quite outstanding. The performance of this new lens is commendable for maintaining the stability of the optical quality in such a large focal range. Moreover, the post-optimization processing of vignetting is very easy nowadays, the correction of post-stage software or direct in-machine processing can solve this phenomenon well.

  User experience

   Tamron 28-200mm F/2.8-5.6 Di III RXD lens F2.8-5.6 aperture specification is the largest aperture in the same lens, this is also this One of the biggest advantages of Tamron lenses. A larger aperture means stronger blur ability and more light intake. Therefore, to a certain extent, it can also meet the needs of blurring and the pursuit of low-sensitivity image quality. The significantly enhanced blurring ability makes this lens with a large zoom ratio look more “sweet”.
