Mine arrived yesterday. I had ordered it just after it was announced (from London Camera Exchange at The Strand)
First impressions are, as with others, very positive. I am pleasantly surprised as it feels considerably lighter than it looks and it balances really well on an OM-1, although light it does not feel fragile, it has that confident well-built feel to it.
OMSystems have moved away from the black box for this but it was well secured within. There is a lens hood and a soft cloth envelope instead of a conventional lens bag. I think I prefer this envelope/pouch as it will fold away when not in use ... although time will tell.
The lens is certainly a good portrait lens although the bokeh is creamy it isn't as good as the 75 f1.8 (hardly surprising) The cat mug-shot is a crop. For macro I expect bokeh to be very good the LED image indicates it will be. Close AF is very quick and focus stacking seems a breeze but time and practice will tell. More to follow.
