Lentearen funtzionamendua

This Rokinon lens is a manual focus and manual aperture lens. It does not have electronic contacts to communicate with the camera body. Therefore, all focus and aperture adjustments must be made directly on the lens.

Eskuzko fokua

The focus ring is located on the front part of the lens barrel. Rotate this ring to adjust the focus. For Micro Four Thirds cameras, it is often recommended to set the camera to a 'No Lens' or 'Shoot Without Lens' mode in the camera's menu to enable shooting with manual lenses.

Due to the extremely wide angle of view and inherent deep depth of field of a fisheye lens, precise focusing is often less critical. For many shots, especially landscapes or street photography, setting the focus to infinity (∞) or a hyperfocal distance can keep most of the scene in acceptable focus.

Irekiduraren kontrola

The aperture ring is located closer to the camera body. Rotate this ring to select your desired aperture (F3.5 to F22). Wider apertures (smaller f-numbers like F3.5) allow more light and create shallower depth of field, while narrower apertures (larger f-numbers like F22) allow less light and create greater depth of field.

Lens Hood integratua

The lens features a permanently attached petal-type lens hood. This hood is designed to block stray light from entering the lens, reducing flare and ghosting, and also provides some physical protection to the front element.

Kamera bateragarriak

This lens is compatible with Micro Four Thirds (MFT) camera systems, including models from Olympus PEN and Panasonic Lumix G series. Ensure your camera is set to allow shooting without a lens attached, as this is a fully manual lens.
