And I have to protest Pål's protestation once again.
Quote: There are no more control over DOF with FF.
With the lenses we have available to buy, there most certainly
is more DOF control available with FF. If we were able to design magical lenses for aps-c, or possible-but-exotic lenses with somehow-affordable prices, then yes, there would be no greater control with FF. But until they make a tiny, good, inexpensive 13mm f/1.8, 16mm f/1.8, 24mm f/1.2, 35mm f/1.2, 120mm f/1.8, etc, well have to depend to FF for those FOV/DOF combos.
Past 200mm, there are affordable options for both formats, and the size/price issue actually starts to favor aps-c.
Quote: You need to stop down more on the larger format to get the same DOF - genereally not seen as a plus (thats why large format have tilt/shift).
If you need to stop down to gain more DOF with FF, you can. With aps-c, you don't always have the ability to open the lens up wider to get less DOF.
Quote: APS have in fact a more useful DOF range as hardly anyone will use shallower DOF than what is possible at F:1.4 and F 1.2 on APS,
Many people do, especially when the subject is more than a few feet away and the DOF has expanded to hold the subject nicely, but not so much that subject isolation is compromised.
Even more frequently, they enjoy shooting f/2.8 zooms and getting f/1.8 DOF capability as an option, or stopping any of their lenses down to f/4 to get sweet-spot blistering sharpness on the focal plane while maintaining a pleasing f/2.5 DOF and subject isolation, for example. It shouldn't require too much imagination to see how these options could be useful for a photographer.
