To get this out of the way, I'm fully dedicated to m43..I have lots of lenses and multiple bodies in the system and believe it's the right balance of lens selection, iq, size, weight etc.. But I also have a bit of a wandering eye. Recently I think I've gotten caught up in the hype from the Sigma DP2 Merrill. Not so much the tech reviews, but the user experiences and samples like: DP2M Photo Gallery by Rick Decker at pbase.com Better in Black and White: Sigma DP2 Merrill: A Real World Review Sigma DP2 Merrill Review — MONO - CULTURE I can't but think this would be a fun complement to my m43 kit..whether hiking or travelling. Or when I'm just in the mood for 'slow photography' (oh I'm very aware of the many, many weaknesses). There is something almost romantic to the slow process though. My G5 is highly functional..but I have to admit that it's not always the most fun to use. Good when I need to get the shot, but not necessarily a fun challenge (heh..my old E-P1 has more of this..."character"). So I suppose my rationale is that for the size, weight, and cost of another high end m43 lens, I could carry around a 45mm equivalent prime that frankly blows away anything comparable (in optimal conditions). Not sure if the comparisons to medium format digital backs are valid, but I do believe that it exceeds everything up to maybe the top of the line nikons and maybe a leica m9 with the very best lenses. A colleague of mine who has many more years of experience thinks I'm chasing..just a case of GAS. He thinks there's too many compromises for the cost and that it would just lead to carrying too much (I'm not convinced that it's much trouble to carry an additional pseudo-compact). I would gladly dump my backup body that I traditionally travel with for it. He argues that if I want an IQ boost for occasion, I should look at the Fuji XE1. I agree that it outperforms m43..but I'm not finding that I need the additional low-light benefits. And I like m43, so I'm not looking to switch systems..nor can I afford to maintain 2 parallel systems. If I bought an XE1 with kit I know I'd start lusting after the 35mm..maybe a wide angle option. And then adapt my OM lenses.. There's something satisfying about the idea of having a small, simple, best of the best IQ camera for $1,000. With no temptation to 'upgrade' or expand it..a nice stand-alone. But is it useful in comparison to the Fuji X system which is also right up there for lens and sensor performance..and obviously could grow with me. Sorry for the essay...just torturing myself here. And an additional thought is I could just splurge on the 60mm macro. Opens up a new style of photography and is something I'm missing focal length wise. Not that the money will burn a hole in my pocket..but I am feeling like indulging in a new toy soon. Would appreciate your thoughts..anyone else in the same boat?
