Re: DOF too shallow - agree.

Using http://www.dofmaster.com/dofjs.html and guessing that Milla was photographed from maybe 4 feet then this results at f/1.8 for 45mm (in inches and M4/3 sensor size chosen)....

So DOF is 1.49 inches and of course if viewed at 100% then that viewing size is above the 8x10 inch print standard that DOF is based on so the DOF shrinks even further.

Even at 5 feet distant the depth of field is still a poor 2.34 inches when viewed at 8x10 inch size.

So f/4.0 would probably be a better aperture for a face so close and slanted away from the camera, also the lens is sharper at f/4.0 if sharpness is what you are after.

Use face detect and set for nearest eye and a tripod so there's no shooter to and fro movement to cause problems.

Regards.... Guy
