I'm real close to the last post here:
EF16-40 f/4L
EF24-105 f/4L
EF50 f/1.4
EF100 f/2.8L Macro
EF70-200 f/2.8L
The 50 gets the least use of all the above, followed up strangely enough by the 24-105, which is my oldest lens now (13+ years) and to me seems a bit soft. If I go mirrorless, that will be my first one to be replaced with an RF.
They don't mix, I've tried, as my wife can attest.
Less gear churn, more actual photography.
