I have the Kit I lens 18-55mm f/3.5-5.6. From what I have read, I can shoot at f/3.5 at 18mm and if I zoom in at 55mm, I get a narrower aperture of f/5.6.
I have also read that the DOF at the telephoto end of a zoom lens is shallower than the DOF at the wide-angle focal length of a lens.
However, according to me, I should be having a shallower DOF at the wide-angle part of my lens (18mm), since I am shooting at an aperture of f/3.5 whereas at 55mm the aperture is only f/5.6.
Am I missing something? I'll be grateful if somebody can enlighten me on this. Thank you.
