Weiying AF 135/1.8 LAB Z

The Viltrox AF 135mm f/1.8 LAB Z offers solid bokeh and useful video features at a budget price, but its optical quality ranks just 21st percentile, making it fall short of the sharper Sigma Art or Sony GM alternatives. The LCD display and stepless aperture ring are nice touches for video work, but stills photographers will notice the difference.

In our benchmarks, the Viltrox AF 135mm f/1.8 LAB Z lands in the 21st percentile for optical quality, which is frankly disappointing for a lens in this price range. The aperture performance sits at the 65th percentile and bokeh quality at 63rd, so the lens can produce pleasing background separation and smooth out-of-focus areas. The autofocus lands at 54th percentile, putting it squarely in the middle of the pack. Viltrox's Quad Hyper VCM motors claim fast and precise focus with face and eye detection, and the 0.72m minimum focus distance is decent for close-up work. Without any stabilization on board, you'll need to rely on your camera's IBIS or keep your shutter speeds up. The 11-blade aperture should give you circular bokeh balls, but the optical correction at 21st percentile means you might see some chromatic aberration in high-contrast situations. For portrait sessions in good light, this lens will perform fine. For critical work where you need razor-sharp results wide open, you're going to notice the difference between this and the competition.

The 135mm portrait market is crowded with heavy hitters. The Sony FE 135mm f/1.8 GM is the benchmark for autofocus speed and optical excellence, and it regularly dominates in our rankings. The Sigma 135mm f/1.8 DG HSM Art offers similar optical performance at a lower price, though with slower autofocus. The Canon RF 135mm f/1.8L adds stabilization and typically edges out Viltrox in our optical tests. What sets the Viltrox apart is that LCD display and the stepless aperture ring, which video shooters genuinely appreciate. But when the Sigma Art consistently scores in the 80th+ percentile for optical quality and the Viltrox sits at 21st, the choice becomes pretty clear for stills photographers. The Viltrox is the budget option, and it shows in the glass.

The Viltrox AF 135mm f/1.8 LAB Z starts around $829, which sounds like a bargain compared to the Sony FE 135mm f/1.8 GM ($1,798) or Canon RF 135mm f/1.8L IS USM ($2,299). But here's the thing: our database shows prices ranging all the way up to $16,475 across vendors, which is either a data quirk or includes some wild bundles. The $829 entry point is what matters for comparison. You get a lot of features for the money, but the 21st percentile optical ranking makes us wonder if that savings is worth it. If ultimate image quality is your goal, spending more on the Sigma 135mm f/1.8 DG HSM Art or waiting for a used copy of the Sony GM might be smarter. The Viltrox makes sense if you need those extra controls (that LCD display is genuinely useful) and can live with slightly softer results wide open.

The Viltrox AF 135mm f/1.8 LAB Z is a full-frame telephoto prime lens built for Nikon Z mount shooters who want that classic 135mm portrait focal length without dropping Sony GM money. It packs 14 elements in 9 groups including 4 ED and 2 high-refractive elements, a bright f/1.8 aperture, and Viltrox's Quad Hyper VCM autofocus motor. The lens also throws in some unexpected extras like an LCD display, dual Fn buttons, and a stepless aperture ring for video work. At 1265g, this is not a lightweight walk-around lens, but the metal construction suggests it can take some abuse. Our database shows this lens scoring highest for portrait work (49/100) and lowest for macro (14.4/100), which tracks with what you'd expect from a 135mm prime. The $829 starting price positions it as a budget alternative to the usual suspects, but the optical performance rankings suggest some compromises were made to hit that price point.

If you're a portrait photographer who demands the sharpest possible results, skip this lens. The 21st percentile optical ranking means you'll get softer images wide open compared to the Sigma 135mm f/1.8 Art or Sony FE 135mm f/1.8 GM, and that difference matters when clients are paying for results. The 4th percentile build quality ranking also raises durability concerns for professionals who beat on their gear. Look at the Sigma Art instead if you want better optics without the Sony price tag, or save up for the Sony GM if you need the absolute best autofocus and sharpness. This lens is also not ideal for macro or close-up work given its 14.4/100 score in that category.

The Viltrox AF 135mm f/1.8 LAB Z is a feature-rich 135mm prime that gives you a lot of lens for less money, but the optical performance rankings are hard to ignore. If you're primarily shooting video and want that LCD display and smooth aperture control, this lens makes sense. If you're a stills photographer who cares about ultimate sharpness and rendering quality, the 21st percentile optical ranking should give you pause. The build quality score at 4th percentile is also concerning and worth watching. For around $829, you're getting a capable portrait lens with some genuinely useful extras, but the competition from Sigma and Sony is significantly better optically. Consider this a budget option with caveats rather than a true bargain.
