On top you can see John Sison 35mm f/1.4 FE lens review. And this is the conclusion of the Samyang AF 24mm f2.8 FE Review by Nic Taylor:
During my time with this lens so far I have been very impressed with how fast and accurate the autofocus performs, even in low light. The fastest of all of the AF lenses by Samyang so far. I think it says a lot that this lens performs so well even on my Sony A7R given the unreasonably bad AF performance of that particular camera when it comes to moving subjects due to it only having the vastly inferior contrast detection AF system. Undoubtedly this lens will perform even better and far more accurately on a later model Sony A7 series camera like the A7iii, the A9 or even an A6XXX series APS-C camera with a phase detection autofocus system. A possible downside to the lens for some photographers may be that due to it’s size it doesn’t feature a distance or depth of field scale. This lens also lacks weather sealing. Samyang’s AF lenses (AF 14mm f2.8 EF & AF 85mm f1.4 EF) for Canon have both featured a rubber weather sealing gasket at the rear of the lens. Maybe this could be something that Samyang introduce on future Sony E-mount lenses. However, this lens is very enjoyable to shoot with partly down to it being so compact and light weight but also the stunning, detailed images that it can produce. It does show some signs of chromatic aberration but this can be easily combatted with a simple click in Lightroom or other editing software. Despite being a lens with a relatively wide focal length it produces pleasing bokeh (out of focus areas) but you need to position the lens pretty close to your subject to get a shallow depth of field with the background. The lens is focus by wire and seems pretty responsive when in manual focus. This lens will no doubt appeal to travel and street photographers looking to carry a compact, lightweight yet well-performing lens and at a very competitive price point. I have a feeling that this lens will do very well for Samyang.
