Overview of the Sony SEL90M28G and Tamron 18-300mm

The Sony SEL90M28G is a specialized macro lens, while the Tamron 18-300mm is a versatile all-in-one zoom lens. Priced at $1,048.00, the Sony lens targets photographers seeking high-quality macro capabilities, particularly for full-frame mirrorless cameras. In contrast, the Tamron lens, priced at $599.00, offers a broader focal range that allows for both wide-angle and ultra-telephoto photography, making it ideal for general use.

Price Comparison

The price difference between the two lenses is significant, with the Tamron lens being about 43% cheaper at $599.00 compared to the Sony lens's $1,048.00. This substantial price gap may influence budget-conscious photographers who seek versatility without compromising on quality. While the Sony lens appeals to those specifically interested in macro photography, the Tamron lens offers greater flexibility for various shooting scenarios at a lower cost.

Design and Build Quality

The Sony SEL90M28G features a dust and moisture-resistant design, making it robust for outdoor use. Its build quality is complemented by a weight of 602 grams (21.3 ounces), which is manageable for handheld shooting. On the other hand, the Tamron 18-300mm is compact and portable, measuring 4.9 x 2.9 inches and weighing 21.9 ounces. Both lenses are designed with durability in mind, but the Tamron's all-in-one nature adds to its versatility in various shooting conditions.

Optical Performance

The Sony SEL90M28G excels in optical performance, boasting advanced spherical elements and Super ED glass that reduce flare and ghosting. It also features a maximum aperture of f/2.8, allowing for exceptional bokeh and sharpness even at close focusing distances. In contrast, the Tamron lens maintains high resolving power from center to corners throughout its 16.6x zoom range. While both lenses deliver excellent image quality, the Sony lens is particularly designed for macro and portrait photography, while the Tamron lens is tailored for a wider array of shooting situations.

Autofocus Capabilities

The Sony SEL90M28G provides instant manual/auto focus selection via a sliding focus ring, which enhances shooting efficiency. Its Direct Drive SSM (DDSSM) ensures quiet and precise focusing, essential for macro photography where subject details matter. The Tamron 18-300mm, equipped with a VXD linear motor focus mechanism, offers best-in-class autofocus that is both fast and precise. This makes the Tamron lens a great choice for capturing fast-moving subjects in a variety of scenarios, including travel and wildlife photography.

Versatility in Shooting

The Tamron 18-300mm is the world’s first 16.6x all-in-one zoom lens for APS-C mirrorless cameras, covering a focal length equivalent to 27mm to 450mm in full-frame terms. This expansive range allows photographers to switch effortlessly between wide-angle and telephoto perspectives. Conversely, the Sony SEL90M28G is a 90mm macro lens that specializes in capturing fine details, making it ideal for close-up shots but less versatile for general photography needs.

Macro Photography Potential

For macro photography, the Sony SEL90M28G shines with a minimum focus distance of just 0.92 feet (0.28 m) and a maximum magnification ratio of 1.0x. This makes it a stellar choice for photographers wanting to capture intricate details in subjects like flowers and insects. The Tamron lens, while capable of macro photography with a maximum magnification ratio of 1:2, does not match the specialized performance of the Sony lens in this regard. Thus, those prioritizing macro capabilities should lean towards the Sony SEL90M28G.

Which should you buy?

Ultimately, the decision between the Sony SEL90M28G and the Tamron 18-300mm depends on your specific photographic needs. If macro photography and high image quality are your main priorities, the Sony lens is the clear choice despite its higher price. However, if you're looking for versatility and a budget-friendly option that covers a range of photographic situations, the Tamron lens is an excellent option. Each lens has its strengths, and your choice should align with your shooting style and preferences.
