I have an old Crumpler 4 Million Dollar Home bag and it's perfect for this pourpose. I fit my R6 with RF 24-105 f4L attached and I have room for my RF 50 1.8 and RF 16 2.8. FIts perfect and small. They don't make these any more but of you can find a bag with similar/same dimensions, you should be all set. Dimensions are: 10.6 x 8.5 x 4.6"
