File B is the K-3

The first file is better to my eye but "de gustibus non disputandum est"

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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


[edit] BUT THEN: the Exif data of the second (the unsharp) image reveals a sensor resolution which matches the K-5, not the K-3. Which could imply one out of the following:
  • The K-3 Image was shrunk using the Nearest Neigbor method (w/o telling us)
    .
  • [conspiration theory] This is a trap, i.e. false sensor resolution information has been injected into the second file using e.g. ExifTool. Suspcious: the first file doesn't have this tag at all. Because I don't assume that Ricoh will have removed this tag between K-5 and K-3, this suggests a manual change to the metadata to the conspiration theorist
    .
  • Does photoshop tweak the sensor resolution tag, along with a resolution change, so that it doesn't mean anything?
    .
  • All cameras after the K20D, i.e. the K-7 and K-5... are vulnerable to shutter blur, according to Falk Lumo's research. Do we see shutter blur of the K-5...? Maybe, this vulnerability has been removed from the K-3 then.

I think we would have hoped the difference would be more obvious:-)

Rather ruined by taking them into LR5 as it reports the software versions. Still got it right before I peeked.

Well I was going from a K5 & was looking for K5iis image quality but with improved AF including LV functionality. The fact they gave me AA control was the cherry. Be interested to see the above scene with AA types as that's one of the first examples I've seen of K3 moire.

second that - very good scene for moiré/aliasing/fake detail testing, not necessarily for testing different cameras, though

There's more detail in file 1 (E.jpg), so I'm hoping it's the K-3.

File 1 = E
try something that's not infinity, missing Focus is why I dumped my K5 for K01/manual.

Come on, it is obvious without pixel peeping. The second one has the cold K-5 colour rendering (easy to fix) while the first one has the unfortunate new trendy dirty brown colour look of the K-3 which seems to be hard to get rid of, at least until good colour profiles emerge.

Image one is K3. There are more details.

How come with the answer written in the thread such that the most techno Luddite can read which camera took what there are subsequent posts that are wrong
Even as a techno Luddite I'm smart enough to realise that with so many pages in the thread, chances are that some smart-ass would have posted a spoiler. So guess what, I didn't read the thread before looking at the images.

However, having voted, and then read the thread, and then looked at the EXIF, I discover that I'm so much a techno Luddite that I'm still not sure how to tell

Different focusing makes comparing sharpness hard, and at the K5 resolution, both look really sharp. When I buy the K-3, the JPEGs will probably not be full size.

As for which is which, The second one seemed more K5-ish, so I went with that. Haven't looked at mentioned spoiler posts or the EXIF.

Spot which one is the K-5 and the D800E

K-5 & D800E scaled to the K-5 native resolution.

"Full frame" is "obviously" "much better". Or isn't?
