A challenge for all those full frame pundits

Go here and see how accurately you can identify which format was used.

67% after 30 pictures. Although many of my hits were between compact vs APSC/FF, and most of my misses were between APSC vs FF.

65% here.. watching the cricket on TV at the same time. Without seeing the shots at full res there's little to differentiate apart from DOF and perhaps accutance.

Now someone should make a test for camera brand Or camera price.
Would probably be just as revealing.

For the first 10 pics, I got about 80% right.

After 32, I got 24 right, so I got 75% right, FF shots are pretty obvious (except some crappy shots).

After 67, I got 47 right, so down to 70%... and was hovering around 70% for some time.

I would like to see a guess APSC and FF only to not have the result skewed by micro and compact comparison...

But for 2/3, FF shots are pretty identifiable for me?

My brother in law has a Nikon D600. All his images look like FF images.
I have a Pentax K-5 IIs. All my images look like APS-C Images.
Sometimes our images look different because we take pictures of different things.

i got tricked by the crappy APS-C shots and the excellent obviously RAW compact shots.

Where the systems are "equivalent" you shouldn't really be able to tell them apart. It's only where they diverge that it should be "obvious" as to which is which.

This reminds me of all the threads about more MP's being unnecessary because a % of the people can't tell the difference. And about all the comparisons between digital and film. Even comparisons between primes and zooms set to equal FL's. The difference of all those improvements by theirselves may be hard to tell sometimes. But it's all those benefits combined that add up to a lot. If it didn't, we would all be taking pictures with our cellphones and be done with it.

There seems to be a misconception that all people want a FF sensor for purely IQ or DOF reasons.
I want the widest possible angle without having to effectively zoom out to get it and thus losing detail (which I suppose could still be considered wanting it for IQ in a way).
I often want to capture the feeling of a place when I take a picture and not just the view through a cardboard tube of one specific object, and that in my opinion requires capturing as wide an image as possible without making everything super uselessly tiny.
It is why I love medium format (which I can't afford), you can take a picture of a whole city and enjoy it as a whole and then inspect an amazing amount of detail in the image when you view it at its original high resolution 1:1 magnification. Find somewhere that you can view an original JPG in full resolution from a 645D if you don't know what I mean.
Even with FF you have to dip into the 24mm focal length range or lower to really capture a whole setting and it costs you detail to do that. I can use my A70-210 F4 lens on my FF film cameras because 70mm is useable with a 35mm size frame if I need to capture stuff fairly close, and yet still enjoy the detail from the zoom of a 210mm if I need to. That is handy in such places as on a boat tour where you might want to get someone on the boat or a large chunk of shoreline with the 70mm, or zoom in on the distant shore better with the 210mm. With APSC 70mm becomes extremely narrow (head shots only indoors) and so I end up switching to my A35-105 and lose the option of that extra 105mm of zoom. Having your zoom ability cut in half sucks.
Its not for the hell of it that Pentax has both the kit lenses starting in the teens for focal length.

EDIT: After checking out that site, I wrote it off as a poor test due to a complete lack of anything to reference the picture to. Anything resized to computer monitor resolution tends to look the same unless its an extreme like medium format or a camera phone, which is indeed one of the best arguments for the smaller sensors being enough. If we were able to see all those pictures at their original resolutions, or see an identical picture taken with the four different sensor sizes the differences would be glaringly obvious.

Sometimes the FF shots are identifiable, sometimes not. Depends on the situation really. Was the picture cropped, is the ISO maxed out? Too much variables. If it's a side by side I think it will be more obvious which is which.

APSC / 4/3rds are indeed good enough for most though. I still really enjoy using APSC, but 16-50/2 and 50-135/2 APSC lenses doesnt exist. So for DOF control I still prefer FF.

FWIW I got 50% correct after around 20 or so. declining success as it goes on
