Got this used, didn't try all features yet, but this is a beautiful, albeit very heavy, lens. This is my third Viltrox lens (first one used although got it from them) and as you can see, I think they deliver good value. Just got it yesterday, and have yet to "pixel peep" but from what I see so far it, delivers optically. Great for faces (human and my cats so far, lol), background separation/bokeh, and low light performance. Fast sharp autofocus. Have not yet tried video yet although I'm less likely to use such a tight zoom on video very often.

This is an absolutely fantastic lens that produces very pleasing and sharp images. The autofocus is very fast and can capture high speed sports without issue. This lens also has the sharpness, and close focusing ability that it can work as a macro after cropping on a high-resolution (I’m using an A7RIV) sensor. There’s just something about the 135mm F1.8 that produces stunning images. Headshots, tight portraits, mid and full-length portraits especially in backlight conditions look magical with this lens. The image included in the review is a unedited straight out of camera JPEG.It is heavy and big, but I feel like those are OK compromises for its price and performance. I was hoping that it would be a net weight savings if I can leave my Tamron 35-150mm f2-2.8 and my macro in the car on wedding days.This issue that makes it unsuitable for any professional photography is the aperture ring. I am a wedding and event photographer and have an assortment of lenses that both have and lack aperture rings. Because not all of my lenses have aperture rings I typically disable aperture rings, or lock the aperture ring so that the aperture control is mapped to a command dial on the body. The issue with the Viltrox 135mm is that the aperture ring cannot be disabled. You can turn the dial to where aperture is controlled by the body, but just a couple of very subtle clicks to the left and the aperture is at f16. I frequently carry two camera bodies and there were times where I found myself shooting at f16 because the aperture dial must have moved over at some point. Another issue is when you see that you are at the wrong aperture, you must turn the dial several revolutions to the right to get back to camera body command dial control. Once you are back to the command dial, the aperture defaults to f4, and then you need to turn the command dial several revolutions to get back to f1.8.During some sports photography I noticed I was at f16, had to turn the aperture control dial on the lens to the right to get to automatic, and then turn my command dial to get back to f1.8. This takes a few seconds and caused me to miss some shots. Fortunately, this was during sports photography I was shooting for fun.The most frustrating aspect of this is it’s just a software choice Viltrox made. There should be an option to disable the aperture ring in the Viltrox app. Once that option is there this will move from a “fun lens” to a lens I can actually use for work. I will also update my review if that software/firmware change is made available.

Optically this lens is really sharp. However, there are some ergonomic issues. The focal range limiter is reversed from native Sony lenses so it is easy to accidently adjust the switch. The lens hood is good quality but it's also really tight against the lens so the rubber edge catches on the lens quite often while trying to remove it.

Super tolles 135mm f1.8. Habe alle blenden Stufen ausprobiert. Fotos die ich gemacht habe alle mit meiner sony sind im s/w und im farbbereich ein Gedicht. Bokey ist super. ist ein traum von objetive.

Das Objektiv macht einen wertigen Eindruck, vor allem wegen des Metallgehäuses. Es ist gegen Staub und Spritzwasser geschützt.Der Blendenring und der Fokusring funktionieren tadellos, sind weder zu leicht- nicht zu schwergängig. Den Blendring kann man auf lautlose Funktion umstellen, was mir sehr gut gefällt.Außerdem finde ich die AF/MF-Umschalttaste sowie die Fokus-Halten-Taste, sehr nützlich.Das Display zeigt zudem sehr praktisch z.B. die Fokusdistanz an. Außerdem kann man Einstellungen und Updates für dieses Objektiv per App, über das Smartphone, vornehmen. Auch hier hat Viltrox gut abgeliefert.Das Viltrox 135mm 1.8 Lab bildet sehr scharf ab, und zwar vom Bildzentrum bis in die Ecken, und das sogar bei Offenblende.Außerdem gefällt mir die tiefe Gegenlichtblende, die innen zudem mit einem weichen Stoff ausgestattet ist, sehr gut.Allerdings gibt es auch negative Kritikpunkte, die das Objektiv für mich unbrauchbar machen.Ich nutzte das Viltrox 135mm 1.8 Lab an einer Sony Alpha 7 Mk. 3. Aufgrund des Eigengewichts des Objektivs (1,35 Kg) ist dieses an der Kamera nicht ausbalanciert. Es ist zu frontlastig. Überhaupt ist es deutlich zu schwer. Mir macht es keinen Spaß, das Objektiv als Kombi mit der Kamera nur 5 Minuten in der Hand zu halten. Wenn man sich jetzt vorstellt, man würde ein oder zwei Stunden damit „shooten“, geht das gar nicht klar. Zumindest nicht ohne Stativ.Auch das Bokeh gefällt mir bei diesem Objektiv nicht, weil es schon leicht neben der Bildmitte eher oval als rund abbildet, was zum Rand hin (logischerweise) noch ovaler wird.Ich werde das Objektiv daher zurückgeben und mir eine Alternative suchen.

Für den Preis - sehr sehr gut
