Overview of the TTARTISAN AF 27mm f2.8 and Viltrox 35mm F1.7 E
When comparing the TTARTISAN AF 27mm f2.8 and the Viltrox 35mm F1.7 E, the key takeaway is their distinct design philosophies and target uses. The TTARTISAN lens is an ultra-compact pancake lens designed for Fuji X mount cameras, while the Viltrox lens is a versatile prime lens compatible with Sony E-mount cameras. Priced at $159.99, the TTARTISAN is approximately 11% cheaper than the Viltrox, which retails for $179.00. The price difference may be a significant factor for budget-conscious photographers.
Design and Portability
The TTARTISAN AF 27mm f2.8 shines in terms of portability, making it an excellent choice for travel photographers. Its ultra-compact pancake design allows it to be easily carried, which is a significant advantage for those on the go. In contrast, while the Viltrox 35mm F1.7 E is also lightweight at 170 grams, its bulkier design may not provide the same level of convenience for travel. The TTARTISAN's sleek design caters to minimalism, while the Viltrox balances functionality with a slightly larger footprint.
Focal Length and Aperture
The TTARTISAN lens offers a focal length of 27mm, which is ideal for street photography and everyday shooting, providing a natural perspective. On the other hand, the Viltrox lens has a longer focal length of 35mm, suitable for portraiture and landscape photography. Furthermore, the Viltrox features a bright f/1.7 maximum aperture, which enhances low-light performance and allows for greater control over the depth of field compared to the TTARTISAN’s f/2.8. This difference in aperture can be critical for photographers who frequently shoot in varied lighting conditions.
Autofocus and Shooting Experience
Autofocus capabilities are another area where these lenses diverge. The TTARTISAN employs an STM (Stepping Motor) system that allows for smooth and quiet focusing, making it suitable for both photography and video recording. Its eye recognition focus feature further enhances its usability for capturing candid moments. Conversely, the Viltrox lens is designed for near-silent operation, which is beneficial for video work, but it does not explicitly mention advanced focus tracking features like the TTARTISAN. This aspect may sway users depending on their primary shooting needs.
Firmware Upgrades and Technology
Both lenses offer modern technological features, but they approach firmware upgrades differently. The TTARTISAN includes a unique USB-C interface on the rear lens cap, allowing for easy firmware upgrades that can enhance performance over time. This design choice not only improves aesthetics but also emphasizes user convenience. The Viltrox lens similarly supports USB upgrades, but lacks the innovative interface design, which could be seen as a drawback for users who prioritize cutting-edge technology in their equipment.
Compatibility with Cameras
Compatibility plays a crucial role in selecting a lens. The TTARTISAN AF 27mm f2.8 is specifically designed for a wide range of Fuji X mount cameras, including popular models like the XS10 and X-T4. Its specialized design ensures optimal performance with these cameras. In contrast, the Viltrox 35mm F1.7 E is compatible with various Sony E-mount mirrorless cameras, such as the a6700 and a6600. This broad compatibility makes the Viltrox a versatile choice for users with different camera bodies in the Sony ecosystem.
Use Cases and Versatility
In terms of versatility, the Viltrox lens stands out as it excels in multiple photography genres, including portrait, landscape, and street photography. Its bright aperture and longer focal length make it a well-rounded choice for various creative needs. The TTARTISAN, while excellent for everyday shooting and travel, may not offer the same level of flexibility due to its narrower focal length and smaller aperture. Photographers who require a lens that can adapt to different situations may prefer the Viltrox over the TTARTISAN.
Which should you buy?
Ultimately, the choice between the TTARTISAN AF 27mm f2.8 and the Viltrox 35mm F1.7 E depends on your individual photography needs and camera system. If you prioritize portability and are a Fuji X mount user, the TTARTISAN's compact design and affordability at $159.99 make it an attractive option. However, if you need a versatile lens for a Sony E-mount camera, the Viltrox, with its superior low-light performance and broader creative applications, might justify its higher price of $179.00. Each lens offers unique advantages tailored to different user preferences, making your choice a reflection of your specific photographic style.
