Rokinon AF IO2418-E 24mm
Its 24mm f/1.8 design packs UMC-coated optics with two ED and two aspherical elements, delivering sharp, flare-resistant images in a weather-sealed, 230g body. The fast STM autofocus pairs with a 9-blade aperture for quiet street shooting and smooth bokeh, while a dedicated astrophotography mode simplifies night sky focusing. This lens is best for Sony full-frame shooters wanting a compact, travel-friendly wide-angle that excels at environmental macro and low-light landscapes.
