Howdy peeps

Last weekend i was shooting at the local tracks with my beloved 70-200 2.8L IS.
When i let this setup rest it hangs on the side of my body, the problem is that i bumped the buttons(since they aren't flat) a few times witch made the lens switch is mode, enable MF ect.
But i managed to see the problem at location so for the rest of the day i tried to make sure that i've used the correct settings.
But when i'm looking trough my pics i've noticed a drop in keeper ratio and i'm curious if that's caused by my clumsiness bumping against the buttons on the lens or my lack of photography awesomeness on that particular moment. 
FOR THE FAST READERS...
Question:
Is there a way to know the lens settings that where used in a particular shot?
I'm mainly interested in the IS-mode and IS-enabled exifdata.
(i've used exiftool
) but that program doesn't show that particular kind of information.
Are the lens settings even recorded in the exif info?
