The 17-28mm f / 2.8 Tamron Lens in III RXD specifically designed for Sony E-mount is able to include full frame sensors such as the Sony A9 and A7, and of course this lens can also be mounted on the Sony A6000 with an APS-C sensor (although effective focal will be experiencing a crop factor equivalent to 26-42mm which is not too wide). In this lens testing opportunity, I used a Sony A7 III camera.
Previously, Tamron made its debut on the E-mount full frame scene with the release of a 28-75mm f / 2.8 lens which was immediately responded positively by many Sony A7 users. From there Tamron went on to make another complementary lens, 17-28mm, so that by bringing these two lenses, Sony A7 users could get focal from 17mm to 75mm. The lens, which at the time of this writing was made in Indonesia, is still in a pre-order status, and it is immediately depleted because it has attracted many people. It is understandable because the 17mm focal is definitely tempting for landscape, interior and travel enthusiasts, and a constant f / 2.8 opening will definitely make this lens more reliable in a variety of circumstances including in low light conditions.
I appreciate the Tamron engineers in designing this lens. With a weight of 420 grams, a diameter of 67mm filter, 9 diaphragm blades, BBAR coating, this lens seems to carry high specifications in a compact package. The physical design of this lens is increasingly attractive with a design that is resistant to moisture (moisture resistant) so it is quieter when shooting in conditions that are somewhat wet. Then what is also important is the matter of the RXD focus motor, I see Tamron is precisely capable of designing a typical mirrorless silent focus motor, very different from the motor on a DSLR lens (OSD for the basic one, and there is USD for the fast / ultrasonic). In lenses with the RXD type, the manual focus ring does not physically rotate the focus element, but the manual focus is electronic, making it more silent and can be used in the DMF (Direct Manual Focus) focus mode on Sony cameras.
Well, enough of the introduction, we go into the two main topics of this lens, namely the focal range and maximum aperture. The focal range of this lens may feel short, with 17mm being the widest focal and ending at 28mm which is also still wide. Why doesn't Tamron make a range of 17-40mm or at least 17-35mm? The answer is because 17-28mm is the focal range that is most likely made to accommodate a relatively small lens size (67mm filter ring) with full frame coverage, and constant aperture of f / 2.8. So if forced can be up to 35mm then the choice is the lens becomes large, or the opening is reduced to f / 4. So here Tamron is once again cleverly composing the focal range of two new lenses for the Sony E-mount, with no overlap of 17-28mm f / 2.8 and 28-75mm f / 2.8 (in the future a 75-150mm f / lens might be made 2.8 for telephoto and portrait needs).
From the test chart test results, I found good sharpness at f / 2.8 aperture with 17mm focal, and there was little vignetting due to large openings. The edges are also still sharp even though the f / 4 sharpness at the edges increases significantly. When the lens is zoomed to 24mm and 28mm sharpness is also maintained properly.

I tested this lens with a retaining layer of BBAR flares for resistance to street lights at night and it appeared that flares appeared very minimal and did not confuse the colors of the subjects being photographed. The problem of distortion is very natural if there is a convex impression because this lens goes into a wide lens, it can be easily corrected in editing if we are photographing something that looks like a solid line like a modern building.
In general, I recommend this lens as a wide quality lens at an affordable price, an attractive alternative to the 16-35mm f / 4 lens and can be used for photography on Sony A7 / A9 cameras or become a more general 26-42mm lens on APS cameras. C, or it can be a lens for video recording because of its wide and large openings f / 2.8 and constant. Here is an example of the photos I took with a 17-28mm f / 2.8 Tamron lens with the Sony A7 III body.
