It says on the Internet that you don't need this anti-alicing filter 'cause it is only put there by the manufacturers as a conspiracy to make your pictures less sharp.
No, using AA-filter is like fighting mosquitos with the napalm.

File one ("E") has more detail, I zoomed into the fence in front of the house. you can see the individual fence posts, they are all blurred together on the other photo.
File one has more dynamic range also.

With these observations, I HOPE file one is the K-3....

You say "fighting mosquitos with the napalm" like there would be something wrong with that.

That is heresy. It says on the Internet that you don't need this anti-alicing filter 'cause it is only put there by the manufacturers as a conspiracy to make your pictures less sharp. So it must be true. And a bit of psychedelic colour on distant water ripples looks really cool.

I think you're onto something here - just imagine "new Pentax K-1P with a selectable psychedelic filter feature" - should be a no brainer for all hippie K1000 owners

Sorry, this comparison could be meaningless, because we may be reviewing just the effect of the (unrevealed) image resizing method on the resolution.
  • If the K-3's image was shrunk using the Nearest Neighbor method, it would have been the sharper image.
  • If the K-3's image was shrunk by any other method (which I assume because Bicubic is default), it was the less sharp one.
Since the 2nd picture is less sharp by a big margin, I assume that that's the one which has been shrunk, which in turn implies it came from the K-3.
If the "test" was done the other way round, i.e. if the K-5iis' image was inflated to 24mp to match the K-3, then the sharpness difference would have been just the other way round.

Secondly (probably mentioned already), the AA simulation mode of the K-3 is unrevealed....
I think your ideas about downsampling are wrong. LR uses an adaptive bicubic in it's default 'export', and that method actually does a good job in translating more resolution into a perceived 'sharpness'. Your examination of the EXIF bears that out. (AFAIK, 'Nearest Neighbor' is not what you want to use if you want to preserve sharpness.)

Can we do a blind test with AF-C and DR?

K-5 & D800E scaled to the K-5 native resolution.
Displayed in a thread here on PF, these flickr embeds are downsampled to about 800 pixel-width, which is such a radical downsize that you'd be hard-pressed to see the difference between the K100D and the 645D.

If I click on the links and look at anything above 1600-pixel width, though, it becomes obvious. Here's a glance at a crop from a 1600-pixel width downsample:

D800, K-5:


Of course lens resolution is at play here too.

EDIT: I see you provided some crops later showing the same thing.

E is the slightly sharper image which is image one. Image 1 is the K-3? but don't really know. There's not much between them though.

E.Jpeg=file 1 it has more detail, more zoom at 1:1 and the k-5 does not do 1/350 second it goes from 320 to 400.

I guessed/voted, then checked the EXIF, and I was right.
Me too.

@Adam: Next time remove all XMP-data from the EXIFs.

And use the same WB and calibration profile, plus convert everything to sRGB on export.

No. It was written so many times, that it's not a secret anymore (if it ever was).
