[0.15x] I have a Sony a7 and i'm totally satisfied with this lens, i think the price is incredible and i think that it will increase in few months because it's simply amazing, the quality it's great. The AF Works very good, better than I expected. The bad thing it's the minimun focus distance about 0.45m. So if you want great quality without pay for a CZ Lens and without use mount adapter this is a very good option.

[50mm] Just got this lens a couple of days ago and I must say, I am impressed. The autofocus is not bad at all. In fact, it's on par with my native Sony lenses. The image quality is awesome. But yes, as others have stated, it is noisy. I shoot mainly video but whichever camera I mount this on will not be recording sound anyway.

[50mm] If an f1.4 35mm is what you are looking for the
Rokinon/Samyang at $400 US this has to be the best bang-for-your-dollar in
photography.  It’s sharp, has gorgeous
bokeh and is solidly built out of metal.  It compares well against options three times
its price.  The only drawback is its
weight and if a light 35mm for use on a gimbal is your goal one of the f1.8
lenses might be a better way to go.

[50mm] Cannot praise this lens enough! It creates such a nice and beautiful cinematic look for my films! I HIGHLY recommend his lens for anybody who is looking to make there films one step better. Great investment and the AF is fantastic, just as good as the Sony lenses.

Grab yourself one, you won’t regret it.

[Autofocus] This lens is amazing for photography but there are little issues that videographers might want to ovoid this lens. The lens has amazing image quality, but the auto focus is some what 80% accurate. It struggles when objects get a little to close which means that lens has to refocus which it takes some tries, but at the end it locks to whatever you want to focus on. The lens makes some noise when Focusing but it’s not that bad compare to the cheap 50 mm f1.8 lens that Sony sells. I’m not really into video a lot but I wanted to test out the auto focus on this camera and I gotta be honest with you, it’s not really that good because it struggles a little but it’s decent and don’t get me started with manual focus because it makes a lot of noise when trying to focus on something. But at the end of the day this is Rokinas first auto focus lens which is not bad and I am actually very satisfied with my purchase because this lens is worth the money! So if your into photography I suggest you pick up this lens as your first lens for you Alpha camera because you won’t regret it. * The bokeh is butter*

[Autofocus] A good lens made better with firmware v33. Increases speed of AF significantly on A7III. Older AF motors are not silent but are not noisy for stills. Good colors, sharpness, and focus fall off.

[Autofocus] Firstly, the noise of the AF isn’t loud enough to disturb a wedding ceremony or anything. It’s not an issue as a photo only guy.
Second, the rendering of the background is very smooth!
Third, the autofocus isn’t great in continuous, it stutters a bit. I keep mine in AFS.
Fourth, it’s a big lens. A little bigger than a typical 85mm f/1.8 and about as heavy.
Fifth, minimum focus distance is quite good! Not a macro lens but I was surprised.
Sixth, chromatic aberrations are very well controlled. I’m pretty picky and I happy. It’s a bit worse at min focus distance. It’s not your typical green and purple stuff either, it’s more blue and orange.

Lastly, I’m very pleased overall. The T-stop is faster than other 50mm lenses and the vignetting is pretty light. Sharpness is good. Colors are good. Contrast is average. Bang for buck is excellent.

[67 mm (Front)] This older version of the lens is definitely showing it's age in the electronics area. But I gave 5 stars because it was on sale, and for the $ it's a beautiful lens that is very fast. The autofocus is probably the main issue. Compared to more modern designs, it's very noisy, and not super fast. So sports would be out. I do mostly live concert shooting, and some interview work, and even with live mics, it doesn't seem loud enough to cause me audio issues. I use all external mics, so if you use the camera mic it would probably cause some issues. The look, clarity and sharpness are all amazing. (For video at least - I cant comment on how pixel peeping photographers would find it.)

[0.15x] Just got it. It did come in 1 1/2 days even though the big snowstorm is raging. I have tried it briefly. A photo is enclosed, taken handheld with a greenish desklamp for lighting. I've noticed on looking at it 100% that there is some fringing, but I'm sure with LR or PS that will go away. Other than that, I have no problems. I might use this for video in which case it's loud on the AF. But for landscape (smaller objects) and portraits, this lens is really beautiful. Snowflakes and bokeh can create wonderful winter scenes. I have other Rokinons, all MF. They are great. This one adds the AF and is even greater! Nice, simple design and all electronic. For the price, you cannot beat it. Get it on sale!
