The TTARTISAN AF 27mm f2.8 is priced at $159.99, making it about 17% cheaper than the VILTROX 35mm f1.7 E, which retails for $179.00. Both lenses cater to different user needs, with the TTARTISAN focusing on portability and compact design, while the VILTROX aims to deliver superior low-light performance and bokeh effects. This comparison will explore various aspects such as design, optical quality, autofocus capabilities, and overall value for photographers using Fuji X and Sony E mount cameras.

Design and Build Quality

When it comes to design, the TTARTISAN AF 27mm f2.8 stands out for its ultra-compact pancake design, ideal for travel and everyday use. Weighing significantly less than traditional lenses, its slim profile enhances portability. In contrast, the VILTROX 35mm f1.7 E, while still compact at 170g, is slightly bulkier but offers a robust metal body that ensures durability and longevity. The clicked aperture ring on the TTARTISAN allows for quick adjustments, whereas the VILTROX includes an extended lens hood that enhances contrast and protects against stray light. This makes the TTARTISAN more suited for those who prioritize lightweight equipment, while the VILTROX appeals to users looking for sturdiness and thoughtful design features.

Optical Performance

The VILTROX 35mm f1.7 E excels in optical performance, featuring a bright f/1.7 aperture that enables exceptional low-light shooting and beautiful bokeh, making it perfect for portraits and street photography. Its optimized design includes 11 elements in 9 groups, including high refractive and extra-low dispersion elements, which work together to minimize chromatic aberrations and distortions. On the other hand, the TTARTISAN AF 27mm f2.8, while not as fast, offers solid optical quality for general photography, focusing on sharpness and vibrant color reproduction. For photographers aiming for top-tier image quality, especially in low-light conditions, the VILTROX is the clear choice.

Autofocus Capabilities

Autofocus performance is another key differentiator. The TTARTISAN AF 27mm f2.8 utilizes a stepping motor that ensures smooth and quiet focusing, along with eye recognition focus capabilities, making it effective for both photos and videos. Conversely, the VILTROX 35mm f1.7 E is equipped with a new STM motor that promises fast, precise, and near-silent autofocus, along with minimized focus breathing, which is beneficial for video recording. If quick, reliable autofocus is a priority, particularly for video applications, the VILTROX offers a more advanced solution.

Price and Value Proposition

In terms of pricing, the TTARTISAN AF 27mm f2.8 is currently available for $159.99, whereas the VILTROX 35mm f1.7 E costs $179.00. This price difference of $19 highlights that the TTARTISAN is about 11% less expensive, making it a more budget-friendly option. However, the VILTROX justifies its higher price with features like a larger aperture and enhanced optical design. Depending on the photographer's budget and requirements, the TTARTISAN may provide better value for those prioritizing cost over advanced features.

Target User Base

The TTARTISAN AF 27mm f2.8 is perfect for casual photographers and travelers who appreciate a lightweight lens that is easy to carry. Its compactness suits those who enjoy street photography or travel photography without the bulk of traditional lenses. Alternatively, the VILTROX 35mm f1.7 E is tailored for serious photographers and videographers who require versatility and superior low-light capability. Its advanced features cater to those who want to capture high-quality images in various settings, making it suitable for both amateur and professional use.

Firmware Upgrade Options

Both lenses offer innovative features that improve their performance over time. The TTARTISAN AF 27mm f2.8 includes a USB-C interface for firmware upgrades, which is a unique design aspect that enhances its aesthetics. The VILTROX 35mm f1.7 E also features a USB-C upgrade port, allowing users to keep the lens compatible with newer camera models. This forward-thinking approach in both lenses ensures users can benefit from ongoing improvements and updates, making them both viable long-term investments.

Which should you buy?

If you value portability, a lower price point, and a compact design, the TTARTISAN is an excellent choice.
