There are two 40mm lenses for the Hy6. Wide enough for most situations and a 35mm lens is on the way. I don't see this as an issue.
Of course horses for courses.
My definition of the 'required' widest lens is this..
You MUST be able go much wider than uncle Bob at the wedding or Roger from IT at the corporate event who has an 18mm on a APS chip ie a kit lens and is shooting those shots over your shoulder
18 * 1.5 = 29mm (35mmFOV)
Admitidly the 35 meets this criterion at about 21mm 35mm equiv
Another way of looking at it is I always had a 20mm on my FM2 since I was 19 and expect to equal that
(I only went for the wider nikons on their tiny chips)
Looking forward to getting back to the simplicity of a 20mm prime on a nikon DSLR
And having bought the 50 for my H1 now I prefer its artistic sence of quality to the HC35 which is now in my 'emergency' bag with my SLRN and 14mm and other Bob beating but ultimately pointless gear
As a pro I must be able to beat uncle Bob
