Review on Samyang SYIO35AF-E 35mm f/2.8 Ultra Compact Wide Angle Lens for 📷 Sony E Mount Full Frame, Black: Optimal Solution for Stunning Wide Angle Photography by Amphai Nanthaklang ᠌

I used it for 3 months and sold it due to poor focus and strong vignetting. I bought it thinking to replace the whale 28-70 3.5-5.6, but the whale turned out to be faster and better. Has some pros 1. Low price for a full frame autofocus lens. 2. Compactness in conjunction with the first generation Sony A7 turns out to be a very "convenient size" for family filming and walking. Its cons: 1. Bad focusing algorithm. He can focus well only at an open aperture. As soon as it closes more than 5.6, he starts to "stupid" and tries to focus on the closed aperture, although he must first open it, then focus, then close it to the set value and only then take the frame. The lens is not suitable for shooting moving objects. 2. Vignetting. It is impossible to use it without correction, the darkened fields of the frame are really striking.
