Samyang 12mm F2.0 AF Ultra Wide Angle Auto Focus Lens for Sony E Mount (SYIO12AF-E) Black

This lens is actually a lot of fun. It is plastic constructed but the build feels pretty solid. There's no manual focus switch as far as I can tell but autofocus mostly does fine. Bit of a challenge for night photography though (star stacking) but nothing major. The wide angle of this lens really looks crisp and nice in most shots. The auto focus works well, but it sounds a bit crunchy compared to maybe a better quality lens. Still, over all works well and photos look good for the price.

Tiene buena velocidad de enfoque y un nivel de nitidez que me sorprendió para la gama de precio. Buena calidad de construcción y además viene en un estuche semirígido que no es común que las marcas incluyan en esa gama de precio.

I’m getting some error issues when I’m using this lens on my A6700. And the eye focus system on this lens doesn’t work perfectly. But it does the job well on my A6400

I got this lens for my ZV-E10, which I use mostly for videography, and I'm very happy with it. Its autofocus works great! I love that it offers an F2 aperture in a small and portable package that still feels very high in quality.

For stills I think anyone would be happy, especially for the price. It's quite sharp in the center and more than serviceable in the corners even wide open, only getting better as you stop down. I will be keeping the lens, but my main issue is that the autofocus during video pulses when focusing on something close to the lens. Obviously being an ultrawide angle getting close to things can be quite common, depending on your shooting style. Especially when used for close up talking head style shots, livestreaming, etc., where the camera is stationary, you can clearly see the focus pulsing and consequently because of the focus breathing the frame is also constantly zooming in and out a little bit.
