A: No IS. I use it with the G85 which has IBIS. Overall I am pleased with the stabilization. If you have the means, I would opt for the OLY mainly for the F2.8 otherwise I am satisfied with the lens. Either option is great!

Q: 10. Will the small core unit line up with side access on the Action X50 backpack?

A: The Shimoda Designs Small Core Unit for Mirrorless Camera was made for smaller interiors than that of the Shimoda Designs Action X50 V2 Backpack (Black, 50L), BH #SHV2AX50B, so you may have to find a way to fill in the extra space, or us the compression straps to hold the core in the correct position, but it should be possible to align the side access zipper with the side access zipper of the backpack.
