I am sorry hear that ( at this stage) you have decided the S2 isnt quite ready judging by your experiences Mac.
I have to say that I am not surprised though - the S2 seems to be in late beta testing phase trials at the moment..
Leica in developing the S2 are on a a bit of an Odyssey with the beta testing early adopters strapped hard on to the ship's mast ( via high price commitment ) whilst enjoying the siren song of promise and going through the associated agonies and ecstasies that accompany such journeys.
Homer underlined the virtue of patience continuously through out his epic poem - a long moral play.
When the system is bug free - it will be an interesting option for many. May the time come sooner rather than later - life is to short for too much angst.
Let me add my 2c from the point of view of a MFDB newbie and (serious?) amateur who is considering the S2.
I had a demo from a dealer for a whole weekend in June. I took about 250 shots (it would have been more with better weather and light and without my mother in law and my father visiting during that very same weekend). Camera worked without any problems; no bugs no nothing.
Camera was easy to use--the dealer did not have a manual and I downloaded one from the internet but only looked up one thing.
I had a surprisingly high amount of keepers, despite the difficult light.
Today I printed one shot of my daughter on a large printer (85x85cm). The shot was taken in fading evening light (1/60 sec at f 2.8 at ISO 160) handheld. Focus was spot on. I did very little PP other than tranforming to B&W and the print looks really great (I am sure one could do much more with the file). It's a different ball game than the M9, at least for large prints. Also, this was about shot No 30 I took with the camera, and I am sure that I could get more out of that beast with some exercise--and it was a head and shoulder shot with the 70mm and not the new 120mm.
So I think the IQ is there--may be not superior than the Hassie of Phase competition, but clearly in the same league. And I did not hear anyone complain about the lenses. I also understood that Marc was happy with the IQ--and the overall handling of the camera.
The only IQ issue I experienced was collar fringing, with a couple of motor cycle shots. I was able to address them with C4.
It may be that the system--being fairly young--still has more bugs than Hassi or Phase. However, for someone like me who is not invested in any MF system so far, the question would be whether to invest in one of these more mature systems, to go for the S2, or simply wait. If one (1) in principle prefers the form factor and ergonomics of the S2, (2) has confidence that Leica will sort things out, sooner or later, and (3) does not need a MFD system right away, going for Phase or Hassi now makes little sens. As others have pointed out, the investment is in the glass (I recall that ptomsu mentioned in this or another thread that he may chance to the S2 if only he could get a decent price for his Hassi). The choice is then between wait or buy now.
I have no idea where I will be coming out, but I found this thread actually encouraging to go for the S2. Clearly, the failure of Marc's camera was annoying--to say the least--but it seems that he was really unlucky. **** happens with every system, and if individual horror stories would determine by purchase decisions, I would be sitting naked in a cave:ROTFL: (I also would not be married and not have kids.). What would concern me would be widespread reports about camera failures etc., but I have not heard about them
Anyway, thanks to all who contributed to this debate.
