Dimension comparison
Design and Portability
When it comes to design and portability, the VILTROX 28mm f4.5 Pancake Lens edges out slightly due to its ultra-compact and lightweight construction. Weighing only about 60g and measuring just 60.3mm in diameter and 15.25mm thick, it is specifically designed for Fujifilm APS-C mirrorless cameras, making it easy to carry around for everyday photography. On the other hand, the TTARTISAN AF 27mm f2.8 is also a pancake lens with a compact design, but it does not specify an exact weight or thickness, making it less clear how it compares in terms of portability. Both lenses cater to travelers and street photographers, but the VILTROX's design promotes convenience with its sliding lens cap, eliminating the need for a separate lens cap.
Optical Performance
In terms of optical performance, the VILTROX 28mm f4.5 offers exceptional capabilities with its two aspherical and two ED lenses. These features ensure sharp, clear images with high contrast, even in challenging lighting conditions. While the TTARTISAN AF 27mm f2.8 does not provide specific details about its optical elements, it does feature an STM stepping motor for smooth focusing, which can enhance the shooting experience. However, the explicit mention of advanced optical elements in the VILTROX lens suggests a potentially superior performance in various lighting situations.
Focusing Mechanism
The TTARTISAN AF 27mm f2.8 boasts an advanced focusing mechanism with eye recognition focus, allowing for accurate and agile tracking of subjects. This feature can be particularly advantageous for capturing moments in dynamic environments, making it ideal for portrait and action photography. In contrast, the VILTROX 28mm f4.5 does not detail its focusing capabilities, which may limit its competitive edge in this area. The emphasis on eye tracking in the TTARTISAN lens provides a distinct advantage for users who prioritize quick and reliable focusing.
Aperture and Light Control
The TTARTISAN AF 27mm f2.8 features a clicked aperture ring, allowing for a more convenient and faster shooting experience. This design enables photographers to adjust exposure settings quickly without needing to navigate through camera menus. In contrast, the VILTROX 28mm f4.5 has a fixed aperture of f4.5, which simplifies operation but limits versatility in varying lighting conditions. While the fixed aperture offers consistent performance, the flexibility of the TTARTISAN's clickable aperture may be more appealing for those looking to take creative control over their shots.
Firmware Upgradeability
Both lenses offer USB firmware upgrade capabilities, which is a significant advantage for future-proofing your investment. The TTARTISAN AF 27mm f2.8 includes a rear lens cap with a USB-C interface, making it easy to enhance performance through firmware updates. Similarly, the VILTROX 28mm f4.5 emphasizes its USB upgradeability, ensuring compatibility with future Fujifilm X-mount cameras. This feature is essential for photographers who want to maintain optimal performance as camera technology evolves.
Price Comparison
The VILTROX 28mm f4.5 is priced at $99.00, making it about 38% cheaper than the TTARTISAN AF 27mm f2.8, which retails for $159.99. This significant price difference may be a crucial factor for budget-conscious photographers seeking high-quality lenses without breaking the bank. While both lenses offer unique features, the lower price of the VILTROX could make it more appealing for entry-level users or those looking to expand their lens collection without a substantial investment.
Compatibility and Use Cases
The TTARTISAN AF 27mm f2.8 is compatible with a wide range of Fujifilm cameras, including the XS10, X-E4, and X-T3 among others, making it a versatile choice for various shooting scenarios. The VILTROX 28mm f4.5 is also designed for Fujifilm X-mount cameras, including popular models like the X-T5 and X-H2. However, its fixed aperture and lightweight design cater more towards casual photography and travel, while the TTARTISAN's flexible aperture and advanced focusing may suit more serious photographers seeking creative control and versatility.
Which should you buy?
In conclusion, choosing between the TTARTISAN AF 27mm f2.8 and the VILTROX 28mm f4.5 largely depends on your specific photography needs. The TTARTISAN offers advanced features like eye recognition focus and a clickable aperture ring, making it ideal for photographers who require versatility and precise control. However, if budget is a primary concern, the VILTROX 28mm f4.5 presents a compelling option at a significantly lower price point while still delivering solid optical performance and convenience. Ultimately, both lenses cater to different types of photographers, so selecting the right one will depend on your priorities in terms of price, performance, and functionality.
