Introduction to the Lenses
When it comes to selecting a lens for your Fujifilm camera, the TTARTISAN AF 27mm f2.8 and the VILTROX 28mm F4.5 XF Pancake are two noteworthy options. Both lenses cater to Fujifilm X-mount users, but they offer distinct features and benefits. The TTARTISAN lens is priced at $159.99, while the VILTROX lens comes in at a more budget-friendly $99.00, making it about 38% cheaper than its competitor.
Design and Portability
The design and portability of a lens can significantly impact your shooting experience, especially for travel photographers. The TTARTISAN AF 27mm f2.8 is an ultra-compact pancake lens, making it easy to carry and perfect for creating stunning visuals on the go. Its compact and exquisite design is tailored for travel, while the lens's STM stepping motor allows for smooth focusing.
On the other hand, the VILTROX 28mm F4.5 XF is also designed with portability in mind, weighing just 60 grams and measuring only 15.3mm in thickness. This makes it the lightest and thinnest lens in the Viltrox lineup, ensuring that it won't weigh down your camera bag during your adventures. Both lenses excel in portability, but the VILTROX has a slight edge in terms of weight.
Autofocus Performance
Autofocus capability is critical for capturing fleeting moments, and both lenses bring impressive features to the table. The TTARTISAN AF 27mm f2.8 employs an STM stepping motor, which enhances its focusing precision and smoothness. This lens also features eye recognition focus, allowing for quick and accurate tracking of subjects, especially useful in portrait photography and dynamic shooting conditions.
Conversely, the VILTROX 28mm F4.5 XF offers efficient autofocus in a compact design, enabling quick shooting without the need for complex setups. It boasts a multi-layer coating that minimizes ghosting and flare, contributing to sharp and clear images. While both lenses provide excellent autofocus capabilities, the TTARTISAN lens stands out with its advanced eye tracking technology.
Image Quality
When it comes to image quality, both lenses promise to deliver sharp and vibrant results, but they do so with different optical configurations. The TTARTISAN AF 27mm f2.8 focuses on providing smooth images and excellent performance for both stills and videos. The design includes an independent clicked aperture, allowing for a more convenient shooting experience.
In contrast, the VILTROX 28mm F4.5 XF features a sophisticated optical design with six elements in six groups, including two ED and two aspherical lenses. This configuration is aimed at delivering exceptional image quality, vibrant colors, and stunning starburst effects. While the TTARTISAN excels in usability, the VILTROX may provide a slight advantage in optical performance due to its advanced lens elements.
Firmware Upgradability
Modern lenses often come with the capability for firmware upgrades, and both the TTARTISAN and VILTROX lenses incorporate this feature. The TTARTISAN AF 27mm f2.8 includes a USB-C interface located on the rear lens cap, making firmware upgrades a straightforward process. This unique design not only enhances the lens's aesthetics but also allows for future performance improvements.
The VILTROX 28mm F4.5 XF does not specifically mention firmware upgrades in its features, which could limit its longevity in terms of performance enhancements. Therefore, those looking for a lens that can adapt and improve over time may find the TTARTISAN to be the better option.
Price Comparison
Pricing is a significant factor for many photographers when choosing between lenses. The TTARTISAN AF 27mm f2.8 is currently priced at $159.99, while the VILTROX 28mm F4.5 XF is available for just $99.00. This substantial difference of about $60 makes the VILTROX lens an appealing choice for budget-conscious photographers who still desire quality performance.
Despite its higher price, the TTARTISAN lens comes with advanced features like eye recognition focus and firmware upgrade capability, which may justify the cost for some users. Ultimately, the decision may come down to how much value a photographer places on these additional features versus the need for affordability.
Target Audience
Understanding the target audience for each lens can help clarify which option might be better suited for specific needs. The TTARTISAN AF 27mm f2.8 is geared towards photographers who appreciate advanced features like eye tracking and firmware upgrades, catering to those who may prioritize versatility and cutting-edge technology.
In contrast, the VILTROX 28mm F4.5 XF is ideal for casual photographers or travelers who may prioritize weight and ease of use over the latest tech features. Its lightweight design and simplicity make it an excellent choice for those who want a reliable lens without the additional complexities.
Which should you buy?

If you are looking for advanced features, superior autofocus, and the ability to upgrade firmware, the TTARTISAN is worth the investment at $159.99.
