In 2023, Viltrox began exploring the higher-end lens market by introducing the Viltrox AF 16mm 1.8 FE for full-frame cameras and the Viltrox AF 75mm 1.2 Pro for APS-C cameras. These models delivered impressive performance at competitive prices. Now, as we approach the end of 2024, Viltrox has launched its most expensive lens to date: the Viltrox AF 135mm 1.8 FE LAB. This review examines how this new addition stacks up against its strong competitors.

Build Quality and Handling
The build quality of the 135mm 1.8 LAB reflects Viltrox’s commitment to high standards, though some changes from previous models have raised concerns. Unlike the 16mm 1.8, which featured an intuitive aperture ring with markings, this lens relies on an OLED display for aperture settings. This design lacks precision, often requiring users to adjust settings via the camera rather than directly on the lens.
A smartphone app accompanies the lens, allowing firmware updates and customizable settings like a personalized welcome screen. The lens features a declickable aperture ring, an AF/MF switch, a focus limiter with three positions, and two function buttons. The casing, crafted from high-quality polycarbonate, houses engraved and painted markings, adding durability.
Despite these advantages, the lens lacks a removable tripod collar, a significant oversight given its substantial weight. Compared to competitors like the Sony FE 135mm 1.8 GM (300g lighter) and Samyang 135mm 1.8 AF (over 500g lighter), this lens is noticeably bulkier.
Autofocus Performance
The autofocus system, while functional, does not match the speed and reliability of leading first-party lenses. A recent firmware update may have improved performance, but this lens might not be the first choice for action photography.
Optical Performance
Vignetting
The lens exhibits light falloff typical of fast 135mm lenses. At f/1.8, light falloff measures 1.6 EV, which improves to negligible levels by f/8. Optical vignetting, which affects the shape of light circles toward the frame’s edges, is minimal compared to other lenses in this category. The lack of aspherical elements eliminates onion-ring artifacts, further enhancing the bokeh’s quality.
Sharpness
The lens demonstrates excellent sharpness across various distances. At infinity, performance is remarkable even wide open, with only minor corner softening. Portrait distances showcase consistent sharpness across the frame. Close focusing delivers a maximum magnification of 1:4, producing sharp results even at wide apertures.
Flare Resistance
Flare resistance ranks among the best for fast telephoto lenses, with minimal ghosting and controlled veiling flare under challenging lighting.
Coma and Distortion
Coma correction is exceptional, and the lens shows negligible distortion, requiring no correction in sample images.
Bokeh
The bokeh is smooth, with minimal optical vignetting and a pleasing rendering in most scenarios. However, structured backgrounds may appear distracting in some instances.
Conclusion
The Viltrox AF 135mm 1.8 FE LAB is a well-engineered, optically impressive lens. Its strengths include excellent sharpness, smooth bokeh, low chromatic aberration, and robust build quality. However, its weight and bulk make it less portable compared to lighter competitors like the Sony FE 135mm 1.8 GM and Samyang 135mm 1.8 AF. Additionally, while the autofocus performs adequately, it lacks the speed and precision of top-tier alternatives.
This lens is a solid choice for photographers seeking a high-quality 135mm lens, particularly for studio or controlled settings. However, considering the fierce competition in this category, potential buyers should weigh the benefits against the limitations before deciding.
