Sorry I "Re-Posted" but I think this deserves it's own thread; I shoot to print at 1mt x 1mt. format. The subject requires size. So I could fall into the category of a "Landscape" photog yet I do not shoot Mtns or trees. Detail is what I sell. So; I am interested in the M 4/3 format for spontaneity and ease of travel. I have seen some Oly prints from the OMD and they are sharp and at 16MP! So the system looks promising. Panny should come forward with their GH3 this Fall and that I await. For my purposes I wish a 24 MP sensor and I'm in! But this is neither here nor there, my question is more scientific. I see a lot of confusing commentary on photo site count vs chip size. Simply I would do the math like this... Other than my 645, I have a old D-Lux5 (A/K/A Panny LX-5) I use for fun, it has a 1/1.7" 10MP sensor, the 1/1.7" sensor is 5.357 times smaller than M 4/3. I have reached 20 x 30 prints (Fuji Lambda) with that D-Lux5 with damn good IQ and without interpolation! So why don't the digital Guru's on these forums believe in the math. If the M 4/3 chip is 5.357 times larger than the lowly 1/1.7" (10MP) chip then shouln't it be able to populate up to 50 MP's with just as much comfortable inter-photo-site spacing that the 1/1.7 sensors photo-sites enjoy? (5.35 x 10MP = 53.5MP) I am sure we would all enjoy 334% better resolution from the M 4/3 bodies! (sorry, more math; 54 MP / 16 MP = 334) Does it not work this way or am I missing something?
