Wide angle lenses are often expensive because they are difficult to design good and easy many side-effects of the large curved lenses. We have tested the Tamron’s latest vidvinkliga supplements, SP 15-30 mm/2.8 Di VC USD.
Tamron has gone from strength to strength in many of its recent releases (here you can read our test of their 90 mm macro and the 70-200 f/2.8). Their 90 mm macro is a classic and their telezoomar has received good reviews and are appreciated by both professionals and amateurs. With its latest addition the SP 15-30 mm f/2.8 Di VC USD, they have developed a real lens with an image circle designed for 35 mm sensors.
Should I translate all abbreviations in the name, you get the following information:
Di means the lens is designed for digital cameras, something that is relatively obvious.
VC stands for Vibration Compensation, so that the lens has image stabilization, something which, although it might seem strange for such a vidvinkligt lens because they are relatively insensitive to camera shake. But it can’t hurt.
USD stands in turn for Ultrasonic Drive which is the piezomotor that Tamron has to push auto focus.
For the abbreviation SP which is also present in the name is simply Super Performance, which shall indicate that the lens is really cool with high performance.
Match the size
When you take the lens in his hand is a burly piece to feel on. It’s almost even thick and weighing just over a kilo. Compare it with the Nikon counterpart 14-24 mm f/2.8 lens Nikon as-is slightly narrower closest to the camera (probably depending on Picture tabliseringen in Tamronobjektivet), slightly shorter and about 100 grams lighter.
The weight difference is virtually negligible, however, is the difference in size is noticeable. We tested the lens with Canonfattning and mounted it on a Canon 1 DX, then experienced not the lens especially heavy and unruly to photograph with it weighed up by the sturdy grip and the weight of the camera. But with a smaller and lighter camera it might probably be perceived as more blade-heavy.
The lens also has a built-in lens hood, which means that there is no option to remove it, or replace it. This is Anleningen first, to get to a more stable the front of the lens, but also to avoid damage on the front element, a risk which of course increases the more curved the is – as is the case for this lens.
Because of the above cause there is no option to use a filter when the threads are missing.
As mentioned above, the lens is quite heavy, but it also contributes to the rich feeling. It’s properly built and nothing in the construction feels cheap.Both the focus ring and zoom ring are comfortable turning and has a soft and comfortable resistance. Autofokusens performance depends of course on what camera you are hanging the lens on, but with a Canon 1DX, we experienced the fast and precise. Relatively silent also.
The images coming out of the camera when using the Tamron’s 15-30 mm f/2.8 is really good, or well, you can’t blame the lens in all cases. It shows hardly any chromatic abberation at all in 15 millimetersläget and when you zoom in to 30 is the little that was almost completely gone.
Vignetting is visible at full opening, but not something that bothers. Dazzles you download something, it becomes less clear. Distortion is also under control. It is of course very difficult to construct a lens with focal lengths without distortion. Least of all is it between 18-20 millimeters, then the lens virtually raktecknande.
But the sharpness? Sharpness is really, really good. Even at full aperture, it’s very sharp, although slightly softer at the edges by 15 millimeters, but it can live with. It doesn’t matter if it darkens slightly, or any step, the focus is on top right from the start. The same impression we get when the lens is zoomed to 30 millimeters.
In short, are you looking for a wide-angle zoom is Tamron’s SP 15-30 f/2.8 Di VC USD is a really good option. Price wise, it is one or a few hundred dollars during the competition, while the performance is equivalent or better, which also makes it affordable.
