How about photography being the collection of light for capture and quality derives form quantity (it does).
MFT captures 75% less light than FF.
Technically it doesn't. Ignoring special cases (like multi-aspect), MFT actually has 25.6% the active sensor area of FF due to the aspect ratio difference. Then the amount of light that hits that sensor depends on the T-stop of the lens and how long your exposure is. You can certainly have the same amount of light hitting the both sensors depending on which lenses you were comparing and your shutter speeds (which IBIS also plays a role in determining). That's the whole point of the "E" argument.
Then you also have to figure in sensor efficiency also to figure how much of that light is "captured".
Don’t get into t-stops.
Most FF lenses have superior ratings over MFT.
And “sensor efficiency” another FF advantage.
The FF advantage is absolute. It’s 2-stops, superior DR, larger shooting envelope from shallow DOF to diffraction limit, and correspondingly larger creative envelope.
The professional market has spoken.
Doug,
One might wonder who on the M4/3 forum truly cares whether the professionals have spoken, or any other twiddle bit that makes FF sensor bodies so exciting.
I wonder why we all should be contemplating our navels whilst we get lectured on the disaster the M4/3 seems to be.
If professionals had spoken through the dslr body it would always have been Canon 1D (Whatever it happened to be at the time - or its NIkon equivalent) and yet quite big slab of actual dslr users could not give a proverbial damn and used aps-c sensored dslr bodies without the snow melting their boots. In fact they were sublimely happy to use the aps-c sensor for the extra reach it gave their FF capable lenses with the crop sensor. Nor did they seem to particularly care to necessarily use EF-S lenses for a tiny size/weight improvements and resolutely mostly continued to use full size lenses without any senses of shame in doing so.
IBIS? What is IBIS? Real pros use don’t need that - they use lens IS with their 1D whatever.
FF has become “a fashion” where its undoubted benefits are touted like totally bald heads save on the expense of a comb. But owners of hair simply put up with the bother of of combing them. They don’t care ....
The FF phenomenon is the short back and sides gone mad - cut it all off, polish it all up and make mine FF like the rest of the mob - and the manufacturers lap it up. Cannot blame them for making/cutting for the new fashion. (My apologies to those who choose that hair style - but in the swinging sixties it wasn’t cool to see fully see your ears - fashions change).
So why is it necessary to pander to the sensor-size cringe? Because it is an argument that FF sensor proponents must always win and get the continued satisfaction of proving it.
M4/3 cameras, aps-c sensor, FF sensor, are all camera systems which people use and get enjoyment out of using - I don’t really see why it is so important to continually have to “prove” what is the best one.
But I think that this might just be the “photography condition” - a sort of disease that afflicts someone just as soon as an image making device is thrust into their hands - it manifests itself in the form of an intense longing to buy something that is better than the actual gear held in the hands - repeat.
In the remote possibility that if we are happy with what we have, it seems that we have to defend our choices against all sort of “logical arguments” That somehow our lives are diminished because it all has been a mistake ....
Then of course we are told that the schoolmaster really likes M4/3 gear, has loads of it, and all the lectures are only to “set the record straight”?
FF is just the dominant format from the last 80 years reasserting itself as sensor manufacturing scales up.
It's the most bang for the buck.
Th FF sensor *always* wins at absolute light-gathering. We NEVER used to have this discussion with film. 120 shooters *always* gathered more usable photons and translated that into a superior image.
Somehow in digital, first in on smaller sensors try to use the inter web to justify their purchase against the facts. It made sense when smaller sensors were cheaper and delivered decent IQ, but that decent IQ was replicated by smartphone sensors so bye-bye P&S market, and larger sensors got cheaper.
It's a very recent phenomenon that people in photography would argue that their smaller format could capture "equivalent" to larger formats, against physics!
In film era 135 stalwarts would point out they had far more portable lenses and much cheaper processing, but none (NONE) would argue "equivalence". They knew it didn't exist on the capture medium.
That these arguments persist discredits the MFT forums members. As FF marches up in IQ and down in price it puts smaller sensors into the box as having to be discount formats based on sensor size. There might be a light premium for marginal compactness now that errorless is everywhere (sorry Pentax).
MFT lost the equivalence war. It's a rout. Panasonic went FF and Olympus cannot stay in their 84 year business. Arguing "enjoyment" isn't the same as arguing market fundamentals.
MFT users can get excellent photos. But FF can get superior ones at almost the same price. So either MFT has to price down to match the inferior output or go away as a format, maybe lingering as a video sensor only.
Dozens of formats have come and gone and MFT is no sacred cow. Olympus bet their biz on one format (except for Tough).........and lost.
If people really want MFT to succeed they need to accept that their format delivers lower IQ and take their "good enough" argument to the manufacturers and demand lower prices reflecting that reality. Failure to do so based on the economics will mean you may in the future have only FF to choose from, or maybe some dumbed-down APS-C like the Z50. All true hobbyist gear will be FF or larger format, as it was in film era (APS and 110 being failures).
