E5 sharper than E3? Not by much.

... you can take up my challenge I set in the OP.

For those who will now insist that I did this test wrong somehow and stacked the deck against the E5, feel free to process the E5 raw anyway you like and I will happily set it against the E3 file.
 
When I did that with my first comparison, I got attacked because ACR is no good for Oly files and I was simply putting the E5 in a bad light by doing so.

See my reply to Goblin if you want to see more (the sarcastic remarks are not for you).

As such, and as per the 'tribunal', I used Oly Viewer (as that's the only other RAW developer I have) for the E5 so no one would accuse me of using not-for-purpose demosiacing algorithms as per Boggis the Cat and backed by the 'tribunal'.
 
If you check the history of this forum, you will see that 'back in the day' these kinds of discussions were very popular and lacked personal attacks. This is how real information about cameras are discovered and marketing rubbish revealed. I learned a lot while people were doing them.
Agreed that it was good back then. If you bother to check the history of this forum you would also identify those responsible for the rot. These would include the usual charlatans who even now persist in disseminating misinformation in the guise of educating. Eg Andy's explanation on "equivalance" which is of course ignored by the charlatans here who purport to "educate" that Oly's f2 is just "marketing rubbish", as you put it.
I'll comment where I want. This is a public forum and you asked for it.
My comment was for you, not me. You can say anything you want. If you love your E5 and don't care about the technicals, I was suggesting you move on because there is nothing here.
Your post called for a visual comparison and a subjective and the determination of a generic and subjective threshold. So you're right in that there is nothing for me here from a technical perspective. I'll move along when I want.
Well everybody agrees that there is a difference. Its just the extent and everyone's using the same kind of generic and subjectives threshold that you yourself have used in this post.

For those of us who have both the E-3 and the E-5 we've done our homework and we know what improvements are available, given the differences in our respective requirements and limitations. To this extent, I thought that the comparison you posted had some utility for those who do not own both cameras. This called for no more than a visual comparison of the pics and consideration of the shooting and processing parameters. It is then for each of us to decide whether the disparity is significant or otherwise.
Now who's been dissing the E-3 on this forum apart from those who insist that the E-3 is not competitive in more ways than one? So who is your target audience?
The forum consensus is that the E5 'lifts a veil from the 4/3rds lenses' and that the E5's weaker AA transforms the camera into something rivaling much higher mp cameras sporting equally good lenses. The implication is the E3 does not 'lift the veil' and the stronger AA destroys its competitive abilities.
There is a clear disjunct in context between the subject matter of your first sentence and that in your second. This is again reason for my questioning your motivation.

In any case, the E-5 does "rival" much higher mp cameras. Oly has cited the extra 2mp, lighter AA filter and proprietary processing. Nobody has yet attempted (wisely) to determine how much of one or the other of these has contributed to the improvement in "sharpness"

The implication you are attempting to draw is untenable. The E-3 has been pronounced uncompetitive by the charlatans before the advent of the E-5. It is not unusual that the E-5 should better the E-3. Your pic comparison in this post helps to show the disparity under the specific conditions. Some of us here will say the E-3 remains competitive and others may not. Unless parameters are objectively defined, there isn't much in this, I would have thought, for you who profess and cherish technicality.

you know how it is. Those who can't resist subjects that are easily to spot one would think they wouldn't be interested in, or even told to move on but can't resist clicking only to complain later that the forum has turned into stupid "drama" battles of which they - somehow - end up being part of.

Such victims!

Do you have a link to this?

Well, I think subjective in photography is important as well because objectivity isn't the full story wherever human beings are concerned (colour perception, for example).

The reason I did this was people were posting 'wow' images from the E5 that didn't look any sharper (to me) than my processed E3 images. So when someone pointed out the availability of these two ORF test files I wanted to see for myself.

Also, I'm unconvinced that an weaker AA (a direction the whole industry is taking) is the way forward. It could just be a fad or worst, a cost cutting exercise backed by marketing rubbish.

AA does so much more that just soften an image. From what I understand it can be the single most expensive component of a good DSLR, so making it weaker and convincing us it is better could possibly simply be a cost cutting operation more than anything else.

I agree with what Claus A said further down this thread.
 
reminds me the many times I ask those pointing to me how I am going too much on theory and little practice, and when I ask to see a small sample of their portfolio (at which point I give a link to mine) they vanish, like vampires in the morning sun or put endless excuses why they can't show even one single photograph that is worth any credentials.

Personally, I do think that a weaker AA filter does / will make the E-5 show a bit more detail. But a lot of the claims have been made shooting it with SHG lens with no vis a vis comparisons vs the E-30 and E-3 with the very same lenses.

I have seen an e-510 shot with the Olympus F2.0 150mm prime, and it looks like a different camera. Same with my e-410 and the F2 50mm. So while I think the E-5 will eek more detail, any of the 4/3rd cameras will look better with the better lenses and the delta may not be as high as thought on first pass. Your comparison suggests that to me.

As for the purple area of the E-5, I wonder if that's just a lens flare (diffused lens flare) or the beginning of some shadow noise. The E-3 has more DR in the shadows than the E-5 (and E-30 and forward). You can even see that much in these shots.

Both the E5 shots have a purple hue, one more than the other. Only the E3 crop looks right to me colour-wise ... and the beach itself looks lit well enough. I think there's moire caused by the tree branches ... but until I get the ORF I can't tell for sure.
 
I think you may have a point here on that end. In a way that's how I have seen noise creep up in four thirds, but this shot isn't a high ISO shot (afaik, haven't double checked that, I should). The trees certainly expose a lot of fine detail that potentially could trigger moire.

Moire or an artifact of moire software removal. Cant' tell for sure but one thing is clear: something's weird in those areas with the E-5. Be it moire related or not.

shot with the 14-54. But it could be a 14-54 + E-5 interaction thing.

Funny thing, looking at the "dither" or small water particles of the ripples, I do think I see a hint of moire, but it's really hard to see.

First of all:

Where did you take the pictures from? Imaging resource? I know that the E-5 pics were shot at aperture eight - while the E-3 samples are no longer available, there.
They are available. That's where I got them. Downloaded both of them last week.
Right, my mistake. Didn't see the button 'current cameras/all cameras'
So, have they been shot at the same aperture and with the same lens?
I assume so, otherwise why bother with test shots to compare?
assuming is not enough. in the case of the E3, they did indeed also hott at aperture eight, but with the E-PL1, for instance, they used aperture 5.6. So, assuming isn't the approaxch that should be used when it comes to executing a proper test.
Why does the image section differ slightly?
Because, as I keep saying, the E5 has 2 million more pixels to display. As it is 100%, the E5 is showing a larger picture.
Now, being an amateur that's something I really don't understand. Both cameras have got an FT sensor and so, the 100-percent pictures should also be of the same sitze, shouldnt they? The one with slightly more pixels than the other? Or am I completely wrong, here?
And, last but not least: If you want to compare an E-5 JPEG vs. an E-3 RAW, why don't you shoot a pic with both cameras in identical conditions, using optimised adjustments at the E-5 and shoot a RAW with the E-3 that you than PP until you are happy with the result.
Do you guys read at all?

What I said in my original post was:

For those who will now insist that I did this test wrong somehow and stacked the deck against the E5, feel free to process the E5 raw anyway you like and I will happily set it against the E3 file.
Why the hack should we correct mistakes you have made as we already know that the E-5 produces clearly more crisp pictures than the E-3 - what doesn't say that the E-3 was a poor camera. It just says that progress never stops and that Olympus made good use of this progress.

So what?
 
Right, keep in mind there is some detail in the E5 file that simply can't be captured by the E3 because it's missing 2 million pixels.
Also bear in mind that we could compare the E-30 to the E-5.
However, does the lighter AA make a huge difference? I would suggest not.

Okay folks, here is a sharpened E3 file from Lightroom compared to an E5 file processed in Olympus's Viewer at its sharpest setting possible. In other words, this is the magical out of camera Olympus jpg that everyone keeps saying blows their minds verses the poor lowly E3 file.
Er, that's an interesting basis for comparison. Why not compare Olympus Viewer JPEGs or Lightroom JPEGs?

Apples and oranges.

OK. I'll post crops from RawTherapee, as that gets the most detail from the raws -- you are asking about detail, right?

Crops of the areas you selected above:













The two I posted earlier in your other thread:

The aperture and shutter speed are the same. The scene isn't quite the same, and the lighting may be different.

The E-5 shot should be slightly larger:

rovingtim appears to be pursuing a religious war against the E-5, for some reason. The facts are not on his side, though -- as you would expect, frankly.

If he wants to post nonsense comparisons they can be countered with better ones. No problem, IMO.
 
... with some of the RAWs presented at imaging-resource. I did't thoroughly check the E-5 and E-3 RAWs for comparability, but some of the E-620 RAWs, for example, are completely out of focus, giving the impression, depending on which detail you look at, the camera wasn't able to produce sharp images at all.

Cheers.

if this were the case, where would a 30% increase in MTF50 using the same lenses come from, or is 30% in your eyes 'not by much'
What do your eyes tell you, Rriley?
my mind tells me that after attempts to flaunt 700% crops as proof of your already specious argument that I need to be careful of what you think you are doing and what might actually be going on. And Im alarmed that you apparently still dont see what was wrong with that

My eyes tell me, and I own both, that E5 presents more detail than E3
i would like to hear the rigour of your method
that seems to be missing
The E3 orf was processed in Lightroom and exported as a jpg. The E5 orf was processed in Olympus Viewer (because people say Lightroom doesn't do Oly justice) with all settings set to normal except noise filter (set to 0) and sharpness (set to +2).

Want to know anything else?
same lens, different cameras, E3 and E5

E5 12-60



E3 12-60



and as you presented a D3x crop before, it was perhaps achieved with this 24-70, it might give you some basis of comparison

D3 24-70 2.8 AF s G ED



and to assist you in making sense of it

Modulation Transfer Function (MTF)

Test results from MTF measurements are defined in three ways with DxO Analyzer: 1. The half Nyquist value, 2. The Nyquist/16 value (linked to BxU values from the "Blur" measurement and 3. The MTF50 value (the smallest frequency preserved at 50%). MTF profiles are provided in R, G, and B channels for RGB images and R, Gr, Gb and B for RAW images, measured at four different locations. Measurements are more precise for low frequencies than high frequencies.

Comparisons between cameras are valid only if camera settings are similar or identical. It is possible to compare limiting resolution directly if the image resolution is the same. An equivalent value for 24x36 mm sensor size is provided to compare cameras with different image resolution. Astigmatism and longitudinal chromatic aberration may be compared directly, regardless of resolution.


still think you are right ?

I agree with you, Claus. After all both cameras ARE Olympus. You would think he was favoring another brand over the "sacred" one. Now he's guilty of trolling because he's praising an Olympus camera? Wow. I guess Bootstrap and the other E-1 afficionados should be permanently banned and relegated to the...Olympus foru...uh oh, I guess that won't work.

The sample scenes are subject to alteration, too. I am also not sure if the lighting is always the same, or if different cameras just produce bad colour casts.

DPR does a better job of keeping their sample scene uniform and well-controlled. This isn't a trivial task, though, so it isn't surprising that most websites struggle with it.

Thanks for the explanation. But I still don't understand the reason for this difference in size. We have got two sensors of the same format, so how can the number of pixels used on this area make an impact on the size of the picture? Rather weird from a logical point of view, I'd say. So, where is the mistake im my thought chain?
