Overview of the Tamron 28-200 F/2.8-5.6 and Viltrox 35mm F1.7 E
The Tamron 28-200 F/2.8-5.6 is priced at $699.00, making it a premium all-in-one zoom lens for Sony mirrorless cameras. In contrast, the Viltrox 35mm F1.7 E is significantly more budget-friendly at $179.00, targeting photographers who prefer a prime lens with a fast aperture. While both lenses cater to Sony E-mount cameras, they offer distinct features that cater to different photography needs.
Design and Build Quality
The Tamron 28-200 F/2.8-5.6 boasts a lightweight and compact design, weighing only 20.3 oz. with a length of 4.6 inches. This makes it suitable for photographers seeking portability. The lens is also built with moisture-resistant construction and a fluorine coating, enhancing its durability and usability in various weather conditions. On the other hand, the Viltrox 35mm F1.7 E is even lighter at 170 grams, which further enhances its travel capability. However, it does not mention weather resistance. While both are designed for ease of use, the Tamron’s additional protective features may appeal to outdoor photographers.
Optical Performance
The optical performance of the Tamron 28-200 F/2.8-5.6 is commendable, thanks to its fast maximum aperture of F2.8 at the 28mm wide-angle end. It accommodates high-resolution imagery, making it versatile for diverse photography styles, including travel, sports, and nature. In contrast, the Viltrox 35mm F1.7 E, with its bright f/1.7 maximum aperture, excels in low-light conditions and provides greater control over depth of field, making it ideal for portrait photography. Both lenses offer excellent image quality, but their performance shines in different shooting scenarios.
Focal Length and Versatility
The Tamron 28-200 F/2.8-5.6 is an all-in-one zoom lens, offering a versatile focal range from 28mm to 200mm. This feature allows photographers to capture a wide variety of scenes without needing to switch lenses. It is particularly beneficial for those who want a single lens for travel or everyday use. In contrast, the Viltrox 35mm F1.7 E provides a fixed 35mm focal length, which translates to an equivalent focal length for APS-C cameras. While this lens is perfect for portraits and street photography, it lacks the versatility of the Tamron's zoom capabilities.
Autofocus and User Experience
The Tamron 28-200 F/2.8-5.6 features an RXD stepping motor unit that is exceptionally quiet, enhancing the shooting experience, especially in sensitive environments. This is particularly advantageous for videographers who require silent operation. The Viltrox 35mm F1.7 E also supports auto-focus and is designed to transmit EXIF information, which adds to the efficiency of using this lens. However, it does not specifically highlight the noise level of its autofocus system. Photographers who prioritize quiet autofocus may lean towards the Tamron, while those who appreciate the simplicity of a prime lens may prefer the Viltrox.
Price Comparison
The price difference between the two lenses is notable. The Tamron 28-200 F/2.8-5.6 is priced at $699.00, while the Viltrox 35mm F1.7 E comes in at only $179.00. This makes the Viltrox about 74% cheaper than the Tamron. This significant price gap means that the Viltrox may be a more attractive option for hobbyists or those just starting in photography, while the Tamron may appeal to professionals seeking high-quality versatility.
Target Audience
The Tamron 28-200 F/2.8-5.6 is ideal for professional photographers and enthusiasts who require a high-performance zoom lens that can adapt to various shooting conditions. Its advanced features make it suitable for diverse photographic endeavors. Conversely, the Viltrox 35mm F1.7 E targets those who primarily focus on portrait photography or street photography and prefer the characteristics of a prime lens. Its affordability and lightweight design make it a great choice for everyday use and travel.
Which should you buy?
In deciding between the Tamron 28-200 F/2.8-5.6 and the Viltrox 35mm F1.7 E, your choice ultimately hinges on your specific photography needs and budget. If you require versatility and superior optical performance, the Tamron lens justifies its higher price with features such as a broad zoom range and moisture resistance. However, if you are looking for an economical, lightweight lens for portrait and street photography, the Viltrox lens offers excellent value for its price, allowing you to achieve great results without breaking the bank.
