Hi! I have Sigma 100-400 with an adapter attached to my A6000 series. This combination is a bit ‘long’ and I need to find a compact way to protect it while travelling/storing it. The lens is covered - no issues here. But the camera sticks out on top of the lens. I do not want to remove it each time when not using it due to sensor dust issues. I was thinking - Is there some kind of a drawstring bag with wide enough opening so I can put it on top of the camera body while it is attached to the lens? Camera/lens is sitting in my (normal) backpack while taking it around, therefore I just need to protect it from dust, light scratches. Bag does not have to be something extreamly thick/protective in this case - it would mostly need to deal with dust issues more (currently). Any other ideas?
