The list author says: "I'm a long time Canon shooter, but since Canon doesn't have an ILC/EVIL (i.e. mirror-less interchangeable lens camera) nor do the have any pancake lenses, even the smallest Canon kit is huge, so I've been thinking about switching or supplementing. This is a list of everything I would eventually want if I were to pull the trigger. The main pros would be, options for lightweight and high quality photography, even more telephoto (2x vs. 1.6x) for a given focal length, arguably better video and a lot of new options for connecting the camera to exotic lenses. The main cons are related to the slightly smaller than APS-C sensors in that DOF is wider and it's not as developed in noise reduction (but it holds its own compared to entry level DSLRS), the lack of either classic f/2.8 zoom lens in either a 14-35 (28-70) or 35-100 (70-200) or in any other zoom for that matter without an adapter to the full size 4/3rds, and that the body isn't as rugged or waterproof... but that's to be expected at this price and size."
"I wish they offered a kit with the GH2 and a pancake lens (like they do for the GF1/2) or at least a cheaper body only option. This is without a doubt at the time I'm writing this the best m4/3rds camera out there, in terms of resolution and features."
"Of course one of the biggest problems with cropped sensors is the multiplier makes your lenses too long... well even after multiplying 7 x2... it's still just a 14mm full frame equivalent, which is still wider than my 10-22 canon lens with a 16mm equivalent."
"This lens is what makes the whole system so attractive, if Canon had a fast thin prime lens like this I would gladly mount it to a rebel or 60d and call that my light camera, but as it is... this pared with any camera (or a GF1 in particular) is very tempting."
"This is the final prime lens and possible one of the most important lenses to have since this is a FULL NATIVE MACRO LENS with image stabilization and Leica optics. It's not a pancake and it's only f/2.8 which is fast, but not prime lens fast... but still, it would soundly round out a still diminutive prime shooter's bag."
"Image stabilized and 200-600mm equivalent and still a respectable f/5.6. An ideal wildlife or to get that long zoom movie look (although I'm sure you'll want to work with a field recorder or wireless audio setup)."
"Since I'd be coming from this system, it would only make sense... but it would be nice if someone could reverse engineer a universal translator that would let the camera control the aperture at least and the autofocus system at best."
"Use this to connect to a telescope or a 500 or 800mm T-mount mirror lens and you could have 1,000 or 1,600mm of reach... sure it would be nearly impossible to hand hold, track or focus with... but it's just too awesome to pass up."
