As they say proof is in the eating

Bit rough and ready but as your both saying the Q will show 4X more DoF than the K3 precision isn't required to prove your wrong

I didn't use a tripod as the results are as conclusive as the logic of the facts.!

One is a crop from a large sensor one straight of a (very) small sensor

Both using same lens same F-stop same shooting distance

1 is cropped to match the other

so which has the massively less DoF as you argument states ?

The only things done to these images is one cropped and both have had there niose profile equalised.

So does cropping give the same DoF if the same lens is use irrelvant of sensor?

This proves without any doubt in my opinion a lens characteristic do not alter by sensor size.

Finally someone posted pic to show the truth!!!
