Ya that is bizarre, I'll try and fix it. Opps not as easy as i thought. Would require redo and reload. I had to strip the exif from the photos, by copy pasting them onto a blank page. So, not my usual work flow. I don't know what happened.
Methodology.
Same tripod placement
K-3 with Sigma 70 macro
K-1 with DFA 100 macro.
K-1 shot at ƒ8, K-3 shot at ƒ5.6 to normalize DoF.
Notes, the 1 stop difference and 100 ISO and light wind made keepers much easier to achieve on APS-c.
Lighting conditions were not always the exact same. It was always bright but not always direct sun.
All shot approx. the same day and time, within 10 minutes. Macro shots, shot in live view, manually focused. Distance shots shot in AF.s
All macros shot on the tripod with the 2 second timer.
I didn't do anything special for the test. Just went out with two cameras instead of one, took two images instead of one, and otherwise just took the images i was interested in that day.

Originally posted by aaacb Norm, would you consider adding an option "can't decide" or similar, I can't see something obviously differenct (which I have the feeling is the whole point of this exercise?)
I'd prefer people just made a best guess. Sometimes we know more than we think we do if we just go with the first though that comes to mind. Don't feel bad, I took them and I don't know, except for the one with the ant because the ant moved, and the dogs, because he's different sizes in the two images. When I post results I'm going to have to look them up in the Temp folder where I saved my work.
I don't find that at all surprising (that it's hard to tell the difference), ƒ5.6 or ƒ8 , good light, 100 ISO, all working to the strength of the smaller sensor.
Now I have to figure out how to do a test that plays to the K-1s strength. The problem being this was easy, this is the way I usually shoot so I really haven't been able to formulate a plan for demonstrating differences. I suspect this will be the "if you shoot this way, you probalby don't need a K-1" thread. Getting some images to show the situations where I would always use my K-1 is going to be more difficult. Any suggestions welcome. I'll probably be coming up with a plan over the next day or two.
