I've test them side by side today and didn't find any difference !
"The most recent one is a "D" version and has some extra pins to allow for firmware modifications and more communication with the body. "
how can i check and upgrade the firmware ?
i 've found a very good deal on the D version, so i was supposed to upgrade my system and selling my non D lens... but tonight, i can't see the point... all images i've shoot side by side are so similar...
did i miss something ?
Both lens are mint anyway.
