I've used several of the Lowepro Cirrus & TLZ belt/shoulder or holster models to fit an FZ28 or G-body m4/3. Just check the interior dimensions on their website for fit. The dimensions are just a bit on the snug side when new.
I always "reversed" the hoods for storage to keep the bag size down.
If you can find one, the Cirrus 110 should work with the grip facing up and the hood reversed.
If you want the lens hood mounted, the TLZ might be the better option, but I got to where I liked the grip up method better for hiking with a belt/shoulder pouch. It seemed less bulky and more compact.
Thanks BB, I"ll have a "Google" and take a look.
