This is now my favourite all round lens.
Really like this lens - It's so small and lightweight, great for just keeping in your bag at all times. It's fast focusing, perfect for street photography. 12mm is wide enough for nice landscapes, and it takes very sharp images (sharper than the standard 14mm-42mm kit lens)
The Mega O.I.S is adequate, helps give you lovely sharp images. However you have to be careful in video mode, it does a good job at taking care of up and down, as well as side to side movement, but doesn't seem to cope well with twisting motion.
There is no manual focus ring. However I've never felt the need for it, since the auto focus on this is so fast and accurate. The plastic connector is not really an issue unless you're a bit heavy handed.
This is now my favourite go to lens, well worth the price of around £110
