Amazon product: Rokinon AF 24mm f/2.8 Wide Angle Auto Focus Lens for Sony E-Mount, Black
This is a great little lens, it’s sharp, light, the autofocus is quick and accurate. The motor is nearly silent and it even comes with a little pouch to keep it in. I own this and the 35mm from Samyang which is the same company. this company is becoming my go to for new lenses. the performance at the price is hard to beat for these lenses.
