Ok so my 12-60 arrived today. before i do any serous reviewing lemme throw out some preliminary observations
firstly, its huge. compared to the kit at least.
the images are all flawless, as can be expected with a lens of this nature. i heard reports of some distortion when shooting at either extreme, but I have yet to notice any. maybe you really need to shoot at a grid to see it.
The focus ring is different from the other zuiko lenses so far, i dont think its digital at all because you can adjust it even when the camera is off and the lens is off the body. this gives a better feel to the focus i think, though i didnt mind the focus on the kit either.
the zoom ring is a bit stiff, but i heard it smooths out after a bit of usage.
and now the autofocus. yes its quite incredible. its honestly the only reason i bought this lens.
ok so its not 100% perfect ALL the time, but its close. very snappy focus, with very little to no seeking.
i find it works better when its zooming down to something closer than up to something further away, but the difference is marginal.
another thing id like to note is that its a great macro lens, it focuses even closer than the stated 25cm. heres some stuff i snapped today:
