Overview of the Products
The Tamron 17-70mm f/2.8 Di III-A VC RXD Lens and the TTArtisan 40mm F2 L are both exceptional lenses designed for different types of photographers. The Tamron lens is priced at $599.00, while the TTArtisan lens is significantly cheaper at $168.00, making it about 72% less expensive than the Tamron option. This price difference reflects the distinct features and intended uses of each lens.
Design and Build Quality
The Tamron 17-70mm lens boasts a moisture-resistant construction and a fluorine coating, which enhances durability and usability in challenging environments. This is especially beneficial for photographers who often shoot outdoors or in varying weather conditions. In contrast, the TTArtisan 40mm lens, weighing just 167-176g, offers a compact and lightweight design, making it an ideal choice for travel and street photography. While both lenses are designed with practicality in mind, the Tamron's robust build may appeal more to those who require ruggedness in their gear.
Optical Performance
In terms of optical performance, the Tamron 17-70mm features a complex design with 16 elements in 12 groups, including two GM elements and one hybrid aspherical element. This results in outstanding image clarity and minimized distortion across its zoom range. The TTArtisan 40mm, while simpler in design, combines ED and aspherical elements to effectively control chromatic aberration. The Tamron’s versatility with a 17-70mm focal length gives it a broader range of use, whereas the 40mm focal length of the TTArtisan is more specialized, ideal for specific types of photography.
Aperture and Low-Light Performance
The Tamron lens has a constant maximum aperture of f/2.8, which is advantageous for maintaining consistent exposure across its zoom range. This feature is particularly useful for videographers and photographers who require flexibility in varying lighting conditions. On the other hand, the TTArtisan lens offers a larger maximum aperture of f/2.0, allowing more light to enter the lens. This can lead to improved performance in low-light situations, making it a better choice for those focused on street or documentary photography during evening hours.
Autofocus Capabilities
When it comes to autofocus, the Tamron lens is designed to leverage Sony's advanced autofocus technologies, including Fast Hybrid AF and Eye AF, ensuring quick and accurate focusing, especially during fast-paced shooting situations. The TTArtisan 40mm also focuses on speed with its STM stepping motor, providing quiet and fast autofocus that is smooth and precise. The Tamron may hold an edge in compatibility with Sony cameras, while the TTArtisan’s autofocus system is well-suited for general photography needs.
Versatility in Use
The Tamron 17-70mm lens is particularly versatile due to its wide zoom range, making it suitable for a variety of scenarios, from landscapes to portraits. It can easily adapt to different shooting styles, making it an excellent everyday lens. In contrast, the TTArtisan 40mm lens is more specialized, focusing on street, travel, and documentary photography. Its moderate focal length offers a balance between context and subject isolation, which can be appealing to photographers who prefer a prime lens experience.
Price Comparison
The price difference between the two lenses is significant, with the Tamron lens retailing for $599.00 and the TTArtisan lens available for $168.00. This makes the TTArtisan lens about 72% cheaper than the Tamron. While the lower price of the TTArtisan makes it accessible for hobbyists and those new to photography, the investment in the Tamron lens may be justifiable for professionals looking for high-quality optics and performance.
Which should you buy?
Choosing between the Tamron 17-70mm f/2.8 and the TTArtisan 40mm F2 L largely depends on your specific photography needs and budget. If you require a versatile lens that excels in various situations and offers advanced features like moisture resistance and superior autofocus, the Tamron is a solid choice. However, if you're seeking an affordable, lightweight lens for street or travel photography that performs well in low-light conditions, the TTArtisan presents an excellent option at a fraction of the cost. Ultimately, both lenses cater to different segments of photographers, making your decision highly personal.
