suggest that you bring a memory card and test a few shots, go home and view it before buying. i admit the design and my longing for a rangefidner digicam got me very interested when i first knew about this camera....28-90 leica lens and a compact body is very very tempting.
so i when to my usual camera shop and loaded my SD card and shot about 40 shots of different ISO and apreture both indoors and outdoors.
when home to see the pictures on screen( dont trust the LCD to check, too small to see anything like noise or sharpness.) decided straight away to forget about the cam.
Why? only shots taken at ISO100 was 'clean'. by clean i meant little or almost non existence noise. from ISO200 above, noise was clearly visible.
again, this is subjective. the pic's noise was much worst at ISO200 than my S2 at ISO800. so the cam loses the non mirror shade advantage from a SLR. however, the noise was better than the ricoh that i have a ISO200. i have printed pic from the ricoh before and think that the pic is acceptable though no way near s2's output. so i suppose the LC1 will give decent photo up to ISO 400 too. Once you use the APS sensor sized DSLR, you will find the noise is a little too much for that price since you can get a canon 300D or D70( the smaller sensor size sure does increase much noise) for about the same price.
so verdict, test it, like it, buy it. expectations are different. for a 1200, i would have gotten it as a carry around daily cam. for 1800, think not worth the price.
