Samyang SYIO3514-E AF 35mm f1.4 Full Frame Lens for Sony E/FE Mount Cameras - Auto Focus, Wide Angle, Fast F1.4 Aperture, Quiet Internal Focusing, Ultra Multi-Coating (Black)

I really like this lens. Have been using it for a while now and wanted to wait before writing a review. Now that I have had some time to experience with it I feel that the AF is not as good as some reviewers on YouTube say it is. At least for video. It hunts a lot! I shoot with Sony a7iii and in video mode it will go in and out focus at times when the focus point has already been set. I don’t feel completely at ease when shooting video for a client because I’m never sure when this lens will go out of focus. I asked a Sony rep about this and he said it may have something to do with the af motors in camera and the af in Lens not responding simultaneously and in conjunction with one another. BUT, when AF is working, the images are spot on and sharp! In photo mode, this lens is fantastic. Great focal length and very sharp images.

Update: 9/19/2018 Stay away from this lens if you're serious about auto focus working and your shots hitting with eye-af. The longer I use the lens the worse it gets. I've had it since December and month after month it degrades in quality. Now I can't use eye af with this at all. Worked great for a while but it now won't focus at all and flutters when in auto focus. Save your cash and get the manual focus ones. Especially if you're going to be using S-Log.

I was hesitant after reading so many reviews dismissing the auto focus, while being audible finding focus my images are tack sharp where they need to be and blurred where appropriate, don't hesitate to pick up this lens.

This lens has non-linear motors, making the auto focus very inaccurate and downright sloppy. It is very jolt-y and stutter-y and focus breathes nonstop. The quality when it does focus is really good, but my intentions for this lens was for video and with the bad focus breathing, the video is really bad. If you were taking pictures with this lens and using manual focus, this lens would be great. I only recommend this to people who will be using manual focus.

This isnt the auto focus version. Its my fault for not knowing so if you are fine with manual focus, its a good lens. I had to return it though because it wasnt the newer version i thought it was.

This lens is a real bargain, the image quality is fantastic even wide open. It works great in single autofocus but not continuous. Also trying to focus manually is frustrating

Excellent lens for the price. I would definitely recommend getting the Lens Station if you purchase to upgrade to the latest firmware and also adjust the manual focus ring to "fast". I also noticed a slight improvement after adusting the punt setting to 0. I've tried the 35mm f1.8 from Samyang and while the weight is significantly lighter and the auto focus is a bit better; but the image quality of the f1.4 is just stellar, the bokeh is excellent and lowlight performance definitely stands out and it seems to let in more light at the same settings compared to the f1.8. Another interesting thing is that the f1.4 is definitely wider than the f1.8 version. Both are really sharp and if you are just a hobbyist like me it more than meets my requirements, I'm very satisfied.

I purchased the lense for my sony a7iii and I loved it for a month! The quality was amazing and I was able to take some really good videos/pictures. One day the lense started clicking when attaching to my a7iii and it stopped working. I have friends with a7iiis and I tried to attach the lense to their cameras and the same issue was happening. I even purchased the samyang emount to update the firmware and still no luck. Unfortunately I was passed the amazon warranty so I can no longer return for a refund so I am stuck with a lense that doesn't. Do what you want but i recommend paying the extra money for a more dependable brand name lense, you are rolling the dice by buying a samyang knowing it can stop working at any second!

Como es comun en esta marca la calidad es excelente, el auto enfoque muy bueno 9 de 10 puntos

للأسف صار لي نفس اللي صار للكثير من اللي كتبوا عن هذا العطل العدسة بدون سبب يموت الفوكس فيها فجأة لا تشتريها

Don’t waste your money on this product. Only sharpness is good and all other things are really bad

TL;DR: You'll love it. Stupid Sharp. AF could be better but it also could be my style, environment, camera. Love it. But I hate it. It's crazy sharp, like, crazy sharp. I found around F2.8 it is absolutely stunningly sharp and detailed. It is quite heavy and quite large on my camera but it feels like it's very solid. The Chromatic Aberration is there, however, it's not nearly as bad as the 50 F1.8. The AF is not the greatest. It's basically completely silent, and it's quite quick but it seems to miss often enough that I may return. However, I am frequently shooting at 1.4 in a low light environment so maybe I ask too much of it. If you're looking for something cheap and amazing - I wouldn't hesitate to recommend this lens to anyone that is comfortable with the price.

I ordered a used ( very good condition ) samyang lens 35mm 1.4 . it said that it will come with the orginal box. but it came with : . no orginal box .no lens hood . the lens not working so stay away
