Should read: As I said, DR is only one of the several metrics that constitute IQ.

Sorry to hear it's a bother for you.

It's a joy for most here....

Why bother with Full Frame when there is Medium Format?--

  • portability and being inconspicuous, then it could be 400% worse
Neither my E3 nor my 5D2 are particularly inconspicuous. They are in fact much the same size. The E-4x0 series were cute little cameras, though. Oly was on the right track there, I think.
  • value for money, then it could be 100% worse
Yet it was a lot cheaper to add a stabilized 300/4 to my 5D2 than it would have been to add a 150/2 to my E3. And I mean including what I paid for the bodies. But you meant the other way around, I know. I wish you were right, but you unfortunately aren't in the general case. The good 4/3 lenses are typically neither particularly small nor particularly cheap (to the extend you can even get them anymore :-()
The comparison was made between M4/3 and FF for cost, value convenience and image quality and you seem to want to discuss 4/3 cameras and lenses instead.

If your point is that the E3 was way too large and heavy, then I agree with you. But it probably had to be that large in order to balance well with the also too large SHG lenses. No one ever claimed that the E3 was an inconspicuous camera.

M4/3.... on the other hand... is a whole different animal.

The DR is independent of sensor size for equally efficient sensors, but, as I said, not all systems that have the same DR have the same IQ, as the DR simply tells the number of levels of light where detail is recorded, but not the quality of those levels.

As I said, DR is only one of the several metrics that constitute DR.

Ah. For sure.

...a quality image. In terms of image quality, the equipment absolutely matters. In terms of a quality image, the equipment plays anywhere from no role to a major role, depending on the photo.

no they are not.

Panasonic is 1399 and canon is 1149

But that would not be a fair comparison, the canon is a much faster lens and of higher quality. it has non-extending barrel and FTM.

a closer comparison is to 70-300 IS USM, 649 USD.

$1139 with free shipping.
dude are you high? that link you posted is for 12-35. Do your home work.
I've put together FF kits occasionally to see what would be involved in to move from my m4/3s kit to a FF kit that would work for me. It's never come out cheaper.
Because it is not cheap. But it is cheaper than M43 for the same IQ.
the cost doubles.
Not it doesnt. body cost triple or quadruple, yes, but by the time you buy the 3rd or 4th lens the cost could well be even.
Maybe it's much cheaper for you, but that certainly doesn't apply to everyone.
We all pay the same price (more or less) for the same product, the only difference is what we choose to buy. if you buy exactly what I buy, you are in for some saving too.
Sorry. My bad.


This will have to do instead.

It doesn't bother me, because I am getting great iq from my system camera, but if all you get is that 10%, why do You bother.

That is not amazon nor USA stock., that is a third party seller from Japan, no USA warranty, may well even be refurb

Medium format will give you superior peformance at low iso and the details provided would be startling even compared to the D800. You chose to not go in this direction and comprimise with features you find important, even though you are well aware of these disadvantages of FF. Sound familar?
 
by the way. What prompts a grown man to crow away on the internet how his toys are superior? It seems as if it was just yesterday, when on the playground a runny nose 3rd grader was doing the same.
 
I rarely get involve in this ethernal dicussions (other than to try to poke fun), but I always look at pictures posted by different personalities, magazines, and other respectable entities like: " the pictures of the year" "most impactacting photos of the century" " photos that made history" etc and I almost never find photos with milky shallow depth of field, high dinamic range, super sharp pixels, CA free, perfect white balance, so what give? Where were the perfect cameras? They say that every picture tells a story, hold on one minute while I pull my Phase one off my car's trunk. ( I wanted to be like A Adams but I did not own a mule) :-(

no it doesnt.

Mf is a different breed of cameras, the are only meant for very specific shooting conditions. every thing else, from fuji jz100 to D800, attempt to cater for a wide range of photography - sunlight or low light, still subject or moving subject.

You remark is analogous to someone in a sports car discussion saying why stop at at Veyron, why not get a F1.

i dont get it either, especially when someone shows up with the camera version of small man syndrome.

Something a bit strange about both these images, IMO.
I specifiably used the RAW test shots from the Focus Numeriqe website as they seem to have the most consistent exposure settings between cameras . I do not have an E-M5 { I am holding out for full FT support, for the lovely 50-200 SWD i recently got} though I do have the GH3 which seems to score almost identically to it. I also have the D800. So i clearly see the advantages and disadvantages of each system , with the combination of mFT and FF ticking all the boxes for me.
Completely leaving aside that base ISO for the D800 is ISO 50 (IIRC) and the base ISO for the OM-D is ISO 200 - in the first image there appears to be huge NR or sharpening applied to the OM-D image; in the second, the point of focus of the OM-D image appears to be the closest edge of the object in the lower right of the image, whereas with the D800 image the focus is on the binding of the book.
The base ISO for the D800 is 100 and using the DXO ISO method puts the E-M5 200 ISO at 107 while it measures the D800 at 74 so not much in it . The only actions taken with both files is to download from Focus Numerique , open in ACR , turn off all NR , minimal default sharpening , re sized to the same dimensions. The first image show the image detail difference.The second is to show the difference in shadow noise even at base ISO .

I am curious why you seem to be suggesting ""huge NR or sharpening"" { they had neither } and just how doing either one would result in the same appearance . NR even the very best is always at the expense of fine detail, whereas sharpening especially ""huge " sharpening typically does the opposite.

Base ISO

Can you shed any light on these observations?
The RAW files are freely available. From the Focus Numerique website. I have certainly not claimed anything is 4x better { assuming we had a an agreed on criteria on which to base the "better" calculation}. Perhaps you could shed a light on how any one could seriously expect a sensor that is almost one quarter the size to match what is considered by all professional review sites and DXO sensor testing to be the best sensor ever put in a DSLR.

DPreview D800 review conclusions
  • Class-leading image resolution at 36.3 MP (with the D800E offering slightly superior resolution)
  • Outstanding high ISO performance in both JPEG and Raw files
  • Wide dynamic range Raw files
Imaging Resource D800 review conclusions
  • Extremely high resolution
  • Excellent image quality
  • Excellent dynamic range
  • Surprising high ISO performance
PhotographyBLOG D800 review conclusions

"On the resolution front, the Nikon D800 delivers images with a truly stunning amount of detail,"

"Raw dynamic range, tonality etc. are also excellent; just what you'd expect from a top-of-the-line camera in 2012."

And just for fun here is the DXO comparison between the D800 , E-M5 and your current camera the E-30.

That would be anyone who challenges your poorly framed arguments and generalisations, yeah?
