peter, i need to comment on this. you know me and have seen me with big cameras in my hand and loving them and their feel. but since i picked up the fuji last week in japan i have changed my mind-somewhat. camera + three lenses < 1kg, built quality is not leica-ish but beats pana and oly hands down, ergonomic buttons on the camera, good but not nikon-ish fast autofocus, very good lenses (the 35mm f1.4 gets close to the summilux in my view, the 60mm macro is fantastic), IQ excellent up to 3200iso, hardly any moiree (you really need to provoke it, even fabric comes out very good normally), excellent optical viewfinder, ok EVF, great live view...i could go on but you get the picture. IMHO fuji has created a marvel with breakthrough technlogy (dual VF, sensor randomized arry). is it perfect, no, there are a few minor issues i do not like (rubber lens caps fall off all the time, the sunshade of the 90mm is ridicolously large, silky pix is a pain..).
can it do things the M9 cannot do? clearly above base iso it beats the M9 hands down, i even concur with steve huff that base iso IQ (including color representation) beat the M9 IQ.
i am going to wait for the M10 but it is hard for me to imagine that leica will get close to the fuji overall package. surely enough, the M9 will have FF, live view hopefully focus confirmation and more MPX but i think that retro-looking leica (see the ridicolous M9 bottom plate) is unable to do a project like fuji did. i'd be happy to err on this.
well we still have to see fuji's quality control, but i have seen enough of leica's. in japan both my leica systems turned into rather useless paper weight (M9 sensor crack and S2 exposimeter and/or shutter failure). i dragged the stuff from saudi arabia to japan and back for nothing.
this is why i bought the fuji and i love it.
give it a try, you will be surprised.
