Yongnuo YN 33mm f/1.4 DA DSM WL Pro 33mm
Une ouverture f/1.4 lumineuse et un moteur pas à pas numérique assurent un autofocus rapide et silencieux, idéal pour la vidéo et la photo de sport. Son boîtier en alliage d'aluminium ne pèse que 370 g, avec des joints d'étanchéité et une touche Fn personnalisable pour une efficacité accrue. Cet objectif convient particulièrement aux photographes de sport et de faune sauvage équipés d'un boîtier Sony E APS-C, malgré sa focale fixe de 33 mm.
Aperçu
The 30-Second Version
A budget 33mm f/1.4 that punches above its weight in autofocus and build. It's not perfect, but it's the best cheap nifty-fifty for Sony APS-C right now.

Les preuves
Performance
Autofocus is the real surprise here. The digital stepping motor puts this lens in the 86th percentile for AF speed, which is genuinely impressive for a budget third-party option. It's quiet and snappy, making it a decent pick for video work too. Optically, it's middle of the pack. The 11 elements in 9 groups with 2 ED lenses do a fine job, but don't expect tack-sharp corners wide open. Bokeh is a bit busy thanks to the 9-blade diaphragm, and macro performance is basically an afterthought at 0.1x magnification. The 500g weight feels a touch heavy for a compact prime, but the all-metal build makes up for it.

vs Competition
The Sigma 18-50mm f/2.8 DC DN is the obvious alternative if you want zoom flexibility, but you lose a stop and a half of light. The Viltrox AF 13mm F1.4 is wider and arguably sharper, but it's a different focal length entirely. The 7Artisans AF35mm F1.8 is cheaper but lacks weather sealing and the AF isn't as quick. If you want a nifty-fifty equivalent for Sony APS-C without spending Sony money, the Yongnuo is the one to beat.

Prix
Value & Pricing
At MXN 5,500 to MXN 6,617 in Mexico, this lens is a steal. The spread across vendors is real, so shop around. The cheapest listing at MXN 5,500 is the one to grab. In the US, you're looking at USD 237 to 244, which undercuts the Sigma 30mm f/1.4 by a good margin. For a weather-sealed, fast prime with reliable AF, that's excellent value.

Overview
The Yongnuo YN23mm F1.4S DA DSM WL Pro is a bit of a naming mess, but the lens itself is a solid budget prime for Sony APS-C shooters. It's actually a 33mm f/1.4, which gives you that classic 50mm full-frame equivalent look. The headline here is simple: you get a bright, weather-sealed prime with autofocus for a fraction of what Sony or Sigma charge. It's not going to win any optical awards, but for the price, it's hard to complain too loudly.
Common Questions
Q: Does this lens work on full-frame Sony cameras?
It'll mount and work, but you'll get heavy vignetting since it's designed for APS-C. Stick to APS-C bodies like the a6000 series.
Q: Is the autofocus loud?
Nope. The stepping motor is quiet enough for video work. You won't hear it hunting in your clips.
Q: Can I update the firmware myself?
Yes. There's a USB port on the lens for firmware updates, which is a nice touch at this price.
Who Should Skip This
If you need macro or creamy bokeh, this isn't your lens. Go grab a dedicated macro or something like the Sigma 56mm f/1.4 instead. And if you shoot a lot of handheld video, the lack of stabilization will annoy you.
Verdict
Buy it if you want a bright, weather-sealed 50mm equivalent for your Sony APS-C camera and don't want to pay Sigma or Sony prices. The autofocus is genuinely good, the build is solid, and the image quality is more than acceptable for the price. Skip it if you need macro or buttery bokeh.
