Panasonic GX1 and the Panasonic 100-300mm lens?

I use the 100-300 on a GX1 (and love both). The biggest issue is the 600mm equiv., not the balance. At any speed below 250 at 300mm a tripod AND remote release is a must. This would be true with anything at that magnification.

Also, this lens has AF difficulties at 300mm in low light and/or low contrast and does have a bit of IQ fall-off at 300mm. So don't confused these with camera movement. The stabilisation works very well at 300mm but can't do the whole job.
