I've got the 1.4EXIII(never had a II so can't compare) but what I've read it's not that it's sharper but you get faster AF with the new big tele's and the 100-400II and the newer body's(5D and 1D class). I did have to MFA the combo, single lens just 1 or 2 units but I believe the combo to be 7 or 8.
Thanks for the info, I appreciate it
, I have yet to really played with the bare lens and with 1.4x it’s been raining here in Seattle. Have a great day. I played with the 1.4x Mark II with my 7D Mark II Indoor and yet it slow to AF but it is still sharp. Can’t wait to try it outside.
