It's the only way to comapre that makes sense if we're comparing images from different systems for sharpness and vignetting.i think sometimes people get a little carried away with DoF based
equivalence
Again, I have no idea what you just wrote.at some point in FL wides in FF arnt ideal for and there widest

photography
The concept of exposure and its relevence is used incorrectly. This will clear that up:no 4/3rds doesnt have fast wides, but they are usable wide open
and wide open on the same aperture, ie 'the same exposure' the DoF is
deeper
What "ills" are you talking about? Vignetting and soft corners? Sure, that's what you get with a more shallow DOF. But at the same DOF, those issues vanish. Are you saying that because 4/3 gets the same DOF at f/2.8 as 35mm FF at f/5.6 that it's somehow superior? That makes no sense at all.and no way do any 4/3rds lenses, kit lenses included suffer the
maladies of may FF lenses which only get on song beyond F8, stopping
down cures their ills
Why do you define "usability" as "corner performance"? Anyway, post your examples. I want to see them. You say, and I quote, "the edges suck isnt trashing FF, its a statement of fact." Prove it. Here's the image you have to beat:cite 14/2.8 L, its wider apertures are useless if you are looking for
quality
14 L II appears to be no better. Having those wide apertures doesnt
make FF have more range, be more usable or better which equivalence
theory suggests. From a practical standpoint FF is defeatable, and
having someone like me, or even you suggest that the corners are soft
and/or the edges suck isnt trashing FF, its a statement of fact.

For corner performance in UWA, true. So what? You have to stop down two stops for the same DOF, and the noise two stops down is the same anyway, even if you need to up the ISO accordingly to maintain the same shutter speed. Again, what's your point?aperture efficiency for IQ, if your FF is more than 2 stops from 4/3rds it lost

What a joke. You post corner crops from 35mm FF from DOFs that 4/3 cannot even attain, and conclude 35mm FF UWA sucks. Unbelievable. I mean, truly unbelievable.i cant see how you wouldnt know this, i dont have to play your game,

Yes, "utter drivel" I say.utter drivel you say ?
You did no such thing. How many times do I have to say it? What is the purpose in presenting corner crops from 35mm FF for DOFs 4/3 cannot even get? Answer me.I gave you 2 L lenses that dont cut it,
Oh you did, eh? Without posting one single image from 4/3 at the same DOF as 35mm FF, you made a "fair and accurate assessment" that the corners of 35mm FF suck. Huh. How about that!you quote another zoom i think in balance looking at those corners, i made a
fair and factual assessment
Bonus. You don't answer any of my questions, and you don't post a single comparative image from 35mm FF and 4/3 at the same DOF, and say that 35mm FF sucks at UWA 'cause the edges from all Canon's UWAs at DOFs 4/3 can't even do are soft.thats it im outta here
Not unless he posts a pic from 35mm FF and 4/3 with the same AOV and DOF that shows 4/3 to be better than 35mm FF.You will never, ever, ever, ever, EVER win an argument with this guy.
It's not up to me whether he "wins" or doesn't. It's up to him posting a pic that demonstrates his point. Posting corner crops from 35mm FF at DOFs that 4/3 cannot even attain is ridiculous.He will never, ever, ever, ever, ever, EVER let you.
You mean "Just recognize that this is someone who's never going to believe that the corners of 35mm FF suck until you post a pic from 4/3 at the same DOF that is a lot better."Just recognize that this is someone who thinks that communication is a
contest that must be win, and move on.
Demonstrating a wide angle, narrow DoF shot he got a comment about vignetting. Vignetting at f1.4 is unexpected? Can you show a similar shot (same DoF, same angle of view) with a small sensor camera without vignetting? (or at all even)it was you that said

Where's the small sensor vs large sensor comparison there? Talking about a lens at 16mm and f2.8 when there is no equivalent 16mm f2.8 crop lens is rather pointless. How good is the FF lens when shot at settings equivalent to a crop lens? In what conditions would you have to use f2.8 and still need corner sharpness? In those conditions could crop do any better?fine Joe, so you are saying this is ok right ?Which of any of the images that you posted are from a sensor smaller

How can anyone say that corner sharpness is not important when
everyone around here claims that total image quality is the most
important element of photography?
Especially when many claim that is the very reason they bought an FF
