Hello Everyone, I apologise to those who have seen this question before...

I’m new here and have very much enjoyed the forum. I was wondering on some input and comments though. In increasing my lens collection, I have been considering a EF 24mm f/1.4L II USM for my 7D. Hopefully upgrade to a 5DIII in years down the line. My question is, has anyone had any AF/auto focusing, front focusing, back focusing, issues with this lens?,…any ideas/suggestions?

Thanks
Sean
