    Re: Canon EF 24-105mm f/4 L IS USM on Rebel XSI



    Ok, so I once again put my stove's hood's light to work, along with a nice black and white logo on a box (PC Organics Oreo ripoffs cookies, before you ask), the cookie's ingredients list, and the text near the tab on a box of some Premium Plus crackers.


    From this I can see, when at 105mm, from 3', that the white of the box is ghosting 3-5 pixels into the black text on the cookie's logo. Aside from this one case with a large contrast with stove lamp glaring off the white of the box, everything else seems fine.


    *shrug* Not sure what the issue was on the other shots I took. Perhaps glare again, though from the sun. Anyway, I can safely say I've now put this lens though it's focus-based paces, and aside from the focus being on towards the near edge in the one ruler test, everything seems fine.
