>>3029036>sensor size affects depth of fieldFocal length and distance from subject & background mostly affects DoF. The fact that a smaller sensor has higher resolution at on a smaller area of the projected image means that smaller sensor = slightly shallower depth of field. This is because higher resolution on a smaller area means the sensor out-resolves circles of confusion (This is also the reason why smaller sensors encounter diffraction issues sooner than lower pixel density FF sensors)
That's why when using a full frame lens on a crop sensor, it's a good idea to use a shallower DoF on the lens' DoF scale if you're scale focusing just to be safe.
Of course, the shallower depth of field due to having a 'high pixel density small sensor' is counteracted by the fact that you're standing farther away from your subject for any given focal length than you usually would on FF due to crop.
>>3028886Armed with this knowledge, your best bet for blurring the background on a compact sensor is shooting macro; ie. longest focal length possible and closest minimum focus distance you can get, which means you'll be limited to shooting small objects. Your camera might even have a macro function or something.

Just thought I'd clarify that.
