Tamron 17- vs TTartisan

Price Comparison

The Tamron 17-70mm f/2.8 lens is priced at $599.00, while the TTartisan 27mm F2.8 lens is significantly more economical at $159.99. This represents a price difference of about 73%, making the TTartisan lens a more budget-friendly option for photographers seeking a quality lens without breaking the bank. Given that the Tamron lens is a high-speed zoom lens, its higher price reflects its versatility and advanced features tailored for Sony APS-C mirrorless cameras. In contrast, the TTartisan offers a fixed focal length lens at a fraction of the cost, appealing to those who prioritize savings over versatility.

Optical Performance

The optical performance of both lenses is impressive, but they cater to different needs. The Tamron lens boasts an outstanding optical design with 16 elements in 12 groups, including two glass molded aspherical elements and one hybrid aspherical lens element. This construction contributes to its exceptional image quality and clarity across the zoom range of 17-70mm. Meanwhile, the TTartisan focuses on delivering sharp images with a simpler design of 6 elements in 5 groups. Although it may not offer the same level of sophistication as the Tamron, its performance is still commendable for a compact prime lens, making it suitable for everyday photography.

Design and Build Quality

In terms of design, the Tamron 17-70mm lens features a moisture-resistant construction and a fluorine coating, enhancing its durability and usability in various conditions. This lens is also designed to be compact relative to its focal range, ensuring it remains portable despite its larger zoom capabilities. On the other hand, the TTartisan is designed as a compact APS-C prime lens, measuring less than 3cm thick, which is ideal for on-the-go photographers. Its lightweight and pancake form factor make it incredibly convenient for travel and street photography. Each lens has its advantages; the Tamron is built for resilience, while the TTartisan prioritizes portability.

Focal Length Versatility

The Tamron lens offers remarkable versatility with a focal length range of 17-70mm, equivalent to a full-frame range of 25.5-105mm. This 4.1x zoom ratio allows for a wide variety of shooting styles, from wide landscapes to detailed close-ups, making it an ideal all-in-one lens for everyday use. Conversely, the TTartisan is a prime lens with a focal length of 27mm, which translates to a 41mm equivalent. While this fixed focal length encourages creativity and composition, it lacks the zoom capability of the Tamron. Photographers must consider their shooting preferences; those who favor zoom versatility may lean towards the Tamron, while those who prefer the simplicity of a prime lens might opt for the TTartisan.

Autofocus Capabilities

Autofocus capabilities differ significantly between these two lenses. The Tamron lens is equipped with advanced features that leverage the autofocus systems in Sony APS-C mirrorless cameras, including Fast Hybrid AF and Eye AF. This advanced focus mechanism is particularly beneficial for video shooting, as it utilizes AI technology to improve stabilization and focus accuracy. In contrast, the TTartisan lens features autofocus with manual focus override. While it allows for manual adjustments, it may not offer the same level of speed and precision in autofocus performance as the Tamron lens. Photographers prioritizing rapid focus for dynamic shooting situations may find the Tamron's capabilities superior.

Use Cases

The Tamron 17-70mm lens is ideal for a wide range of scenarios, including everyday photography, portraiture, and videography, thanks to its versatile zoom range and effective stabilization features. Its moisture-resistant design also makes it suitable for outdoor use in various conditions. On the other hand, the TTartisan lens is perfect for street, travel, and close-up photography, owing to its compact size and lightweight design. Its bright f/2.8 aperture allows for good performance in low-light environments, making it a great option for casual shooters who prioritize portability and ease of use. Each lens serves distinct purposes, catering to different types of photographers.

Brand Reputation and Support

Tamron is a well-established brand known for producing high-quality lenses with reliable performance. The Tamron 17-70mm lens reflects the brand's commitment to innovation and optical excellence, making it a trusted choice among professional and amateur photographers alike. The TTartisan brand is newer and may not have the same level of recognition, but it has garnered a following for providing affordable and functional options for Fuji users. Both brands offer unique advantages, but Tamron's longstanding reputation may provide some buyers with added confidence in their investment.

Which should you buy?

Choosing between the Tamron 17-70mm and the TTartisan 27mm lenses ultimately depends on your specific photography needs and budget. The Tamron lens, priced at $599.00, offers versatility with its zoom capabilities, superior autofocus features, and robust build quality, making it an excellent investment for serious photographers who require a reliable all-in-one lens. However, if you're looking for an affordable, compact option that still delivers good image quality, the TTartisan lens at $159.99 is an attractive choice. It excels in portability and ease of use, particularly for casual shooters and those on a budget. Consider your shooting style and financial flexibility when making your decision.
