Hoping someone could help me understand some basics with regards to wide or ultra wide angle lens. From what I can see, when you pay more for pro quality lens, you get larger aperture of lets say 2.8. I understand this is better glass and allows more light, but what I canít seem to get is why you would need such large apecture for wide angle lens, which are mostly used for landscape where people tend to use higher apertures to get more DOF? Am I missing something here?
Example would be Nikon 14-24 2.8 vs 16-35 f4? Obviously there is the 3mm in length
Hope your all able to help me understand this better
