| I'd argue that 4/3 is not intended to, nor will it ever, compete with FF 35mm sized digital for IQ, because whatever sensor technology advances there are that will imrpove the ability to put more on a given chip size will also benefit FF 35mm size chips, i.e., they will always be better. 4/3 is shooting for (pardon the pun) a niche market based on convenience (i.e., size/weight of equipment) rather than IQ. Don't know how successful they'll be, since 3rd party lenses for 4/3 (e.g., Sigma) are variations of 35mm FF lenses, and so much of the size/weight equipment benefit may be lost (for anyone's lenses but their own, at least). In the end, I think 4/3 will be relatively short-lived, for the same reasons that 1/2 frame 35mm and APS were. Size matters. |
