Samyang Camera Lense 14 mm f/2.8 IF Nikon 14mm f/2.8

Hi, I wanted to get an ultra wide angle lens for very very sporadic use; I didn't want or need a premium brand, for the use I have already told you I'm going to give it: I have good online references of this lens, and I haven't had time to try it out yet. At first I didn't understand that I had to close the aperture and then control it from the camera and the test photos I've taken seem fine; I want it for landscape photography and with so many clouds lately with DANA I haven't been able to, but I will be able to. Thanks for the attention after the purchase. Best regards.

Estou com dificuldades em encontrar focus... Distancia escrita não é real! Vou testar infinito com estrelas, (teste final) Acho que falta calibração. Foi calibrada a lente antes da venda? Obrigado
