Tamron introduced the first constant-aperture full-frame ultra-wide-angle zoom lens with built-in image stabilization in the year 2014. This lens was manufactured by Tamron. Even though I’ve never used the lens, numerous photographers have praised its amazing performance and versatile nature. A little jump forward in time reveals that the 15-30mm f/2.8 Di VC USD G2 is an updated version that was released today. It features an upgraded design as well as new technology.
Tamron SP 15-30mm F-2.8 Di VC USD G2 Ultra Wide Angle Lenses
This ultra-wide-angle zoom lens from Tamron, the 15-30mm f/2.8 G2, is, like its predecessor, rather huge and hefty, but it comes at a price that is reasonable. It does not have a lightweight wide-angle zoom range like Tamron’s 17-35mm f/2.8-4 lens, but it does have a longer focal length and an aperture that remains constant at f/2.8 throughout the entirety of its zoom range.
While the 15-30mm f/2.8 lens is conceptually very similar to a 14-24mm f/2.8 lens, it offers a touch more zoom at the expense of a maximum field of view that is marginally narrower. Let’s take a more in-depth look at the construction, capabilities, and overall performance of the Tamron 15-30mm f/2.8 G2 lens.

Lens Design and Handling
The Tamron 15-30mm f/2.8 Di VC USD G2 lens certainly doesn’t come in the category of lightweight optics. It is a rather large and hefty lens, but it feels great in the hands and balances well with a large full-frame DSLR, such as the Canon 5DS R that I used to test the lens. Despite its size and weight, the lens has a nice feel.
Over 5.7 inches (145 millimeters) in length and weighing just over 2.4 pounds (1,100 grams), the 15-30mm G2 is available in a Nikon mount version measuring over 5.6 inches (142.5 millimeters) and a Canon mount version at over 5.7 inches (145 millimeters). The greatest circumference of each design measures 3.87 inches (98.4mm).
When the focal length is adjusted, the lens features a front element that is bulbous and slides somewhat back and forth as a result. Because of the way the lens was constructed, installing front filters can be difficult because there is no screw-in mount.
The Canon model does come equipped with a rear filter slot where drop-in filters may be inserted. The lens comes with a lens cap that slides on and has a built-in lens hood that is in the shape of a petal. This lens hood does a decent job of reducing lens flare in the majority of scenarios.
The 15-30mm f/2.8 has a structure that is resistant to moisture, which includes a number of seals and a gasket surrounding the lens mount. This lens is designed for use when photographing in challenging environments. During the period that I used the lens, it performed well in both damp and chilly environments, and the fluorine-coated front element was a breeze to dry and clean.
Quality of the Image
There are a total of 18 elements distributed across 13 groups in the Tamron 15-30mm f/2.8 G2 lens. It has three low dispersion elements, a pair of glass-molded aspherical elements, and one eXpanded Glass Molded (XGM) element, which are all examples of Tamron’s most recent advancements in optical technology.
In addition, the lens features Tamron’s innovative AX (Anti-reflection eXpand) coating on big, curved elements as well as eBAND and BBAR coatings on other elements. These coatings work to reduce ghosting and lens flare while simultaneously enhancing contrast and color. Even when shooting with the aperture wide open, the camera produces images of exceptionally high quality over the whole focal length range because of its design and its particular characteristics.
The crispness in the center is excellent when viewed at 15 millimeters. In point of fact, there is very little that can be seen to separate a picture that was shot at f/2.8 from an image that was shot with the aperture stopped down, unless you are examining the image at 100 percent or beyond, or looking very carefully at a big print. The sharp performance in the middle of the frame while shooting wide open is outstanding. However, there is a significant amount of vignetting at f/2.8 and some at f/4; this is an issue that may be remedied by slowing down the aperture to f/5.6 and beyond.
Chromatic aberrations are largely eliminated by the use of a lens with a focal range of 15-30 millimeters. When confronted with very difficult circumstances, there are a few minor difficulties, most notably with purple fringing, although there is also some magenta and green chromatic aberration.
On the other hand, this flaw is fairly simple to fix in raw photos. You can see the entire scene, as well as two crops, down below. The first crop is a raw image that has not had any chromatic aberration correction applied to it, and the second crop is an image that has had chromatic aberration applied to it using Adobe Camera Raw’s easy one-click chromatic aberration correction.
Even when shooting at f/2.8, the Tamron 15-30mm f/2.8 Di VC USD G2 lens delivers really impressive performance over the entirety of its focus range. There are only a few minor issues with the optical performance, such as some vignetting at f/2.8-4 throughout the entire range, ranging from minor to moderate, and some somewhat soft corners at f/2.8, especially at longer focal lengths. These issues are not enough to prevent the lens from being a good choice for most users.
In most cases, distortion is easily managed, and similar to vignetting, it is not difficult to correct in post-processing if it becomes an issue throughout the course of a given shooting circumstance. With its excellent Vibration Compensation technology and superb optical performance, the Tamron 15-30mm f/2.8 G2 lens makes it simple to take photographs that are sharp in a wide variety of settings.
Experience with Firearms
When utilizing an ultra-wide-angle zoom lens, there are a lot of aspects of the shooting experience that need to be taken into consideration by me. Image quality across the frame and over the whole focal length range is my top priority when choosing a lens. When it comes to the 15-30mm f/2.8 G2 lens, its performance is really satisfying, especially when the aperture is set down. However, the lens does not facilitate the use of front filters in an easy manner, which is one of the areas in which it falls short.
There is always a solution available for those who are prepared to alter their lenses and/or their filter holders, but the ability to simply screw in a circular polarizer and easily utilize neutral density filters is something that I place a significant amount of importance on. The Canon model is equipped with a rear drop-in gel filter attachment, which is a convenient feature; however, this component is missing from the Nikon model.
The autofocus and vibration compensation of the 15-30mm f/2.8 G2 lens are driven by two microprocessing units and are driven by a USD (ultrasonic silent drive) motor. Both of these features are included in the lens. The ultimate result is autofocus performance that is rapid while maintaining a low level of noise. In addition to having remarkable performance when it comes to focusing, the lens is also able to focus pretty tight. The closest focusing distance of 11 inches is maintained consistently over the entirety of the zoom range (0.28 meters).
An Overview of the Product
(From Tamron lens literature) Tamron is pleased to announce the debut of a new high-speed ultra-wide-angle zoom lens for full-frame DSLR cameras. This lens, the SP 15-30mm F/2.8 Di VC USD G2 (Model A041), features a fast aperture of 2.8. On September 21st, the new model will be available with a Nikon mount, and on October 12th, it will be available with a Canon mount for a suggested retail price of $1299.
Tamron has a well-established reputation for producing extremely high-quality wide-angle zoom lenses with its Model A012, and with the release of its new SP 15-30mm F/2.8 Di VC USD G2 lens, the company continues the heritage of great optical performance (Model A041).
The distortion and lateral chromatic aberrations that are so frequent in wide-angle photography have been considerably reduced thanks to the incorporation of an XGM (expanded glass molded aspherical) lens element, as well as several LD (low dispersion) lens elements.
In addition, an anti-reflection coating known as AX (Anti-reflection eXpand) that was recently created has been utilized to cut down on ghosting and flare to an unprecedented degree. This ultra-wide-angle zoom lens with a fast F/2.8 aperture achieves remarkable results in terms of its optical performance. In addition, the camera’s built-in Dual MPU (Micro-Processing Unit) offers much better autofocus speed and precision, as well as picture stabilization.
