I literally spent 8 weeks of intensive research into the purchase of a digicam.
Choices were, DP-1, GX200, GRDII ---- all had pro's and con's and I just couldn't decide which would eliminate others; Handling, IQ, Size, Speed, B&W capabilities (Tri-x Rodinal like) so put on my dancing shoes and purchased all three in order to test them out over a period of 14 days after which I would have to send 2 back.
After having tested all 3 for quite a lengthy amount of time I still couldn't make up my mind, but as how it goes someone often will do this for you;
Calumet UK offered the GX200 for 238 GBP, very cheap I thought so I returned all 3 to Amazon and purchased the GX200 (Calumet), at a bargain. The day after the local camerashop in the january end sale offered their last DP-1 for 339€ I managed to deal them down to 275€ alongside the purchase of a regular Panasonic G1 which I was going to buy anyway, and was similarly priced than Amazon where I usually buy my stuff.
I like the DP-1 but this requires a Zen like attitude towards photography which I don't always have, or which is not always possible, but all in all IQ wise definitely very nice, looks a lot like film actually when shooting color. Anyway I have that and I use my Leica 28mm viewfinder on it.
I actually really like the versatility of the GX200, the step zoom 1:1 format good color images up until 400, nice B&W at 800 (I use Aperture and the NIK software package for Aperture) and very intuitive to use.
I stepped down form DSLR after coming to the conclusion I never took it along for it's weight and size, I also realized I disliked the IQ of DSLR's, very nice for family shots but not the sort of thing that warms me up as a hobby, I like the rough, but detailed non-plastic images, be it ghosted out of focus or even blurred, images with character and atmosphere, which up until now the GX200 has been able to provide. The DP-1 provides nice landscapes and architecture fantastic realistic film like color and the Panasonic G1.... well this keeps my wife happy since she like the DSLR type images.
Prior to the DP-1 and GX200 I did try the LX-3 and the G10, both didn't last 48m hours and were sent back after PP'ing the first 50 images (yes... Amazon loves me!)
So actually I think I have found my turn in digital photography. I am still looking at a bargain for the GRDII which I like also, but these will come upon announcement of the GRDIII most probably, but I can wait for that.
I am still in an introductory phase but will post some images shortly to this nice forum.
