Hi my scenario is imaginary as I was hoping to understand how lens work better.
1) If I have a window grill and I used a lens (e.g. 50mm f1.0) to take through it, will the quality of the photo be affected compared to one without any window grilles?
2) Same scenario, but if I am only taking center crop of the photo, will the quality of the photo be affected?
3) Same scenario, but if I am using canon 3x digital zoom (T3I), will quality of photo be affected?
I anticipate some people will say "Just open the window grille and take. But answers to the question will really help me deepen my understanding on lens. I think it a bit related to scratch and dust on lens.
