Hey All, This is getting silly! DEP cannot work if you are busy mucking up the exposure! The whole point of DEP mode is to use the camera's processor to set the aperture for the DOF you want, if you change the f/stop DEP cannot work, if you change the shutter speed your exposure will more than likely be off. If you need to adjust the exposure use exposure compensation. Shifting the exposure in (P)rogram mode allows you to change the shutter or aperture values but the EV remains the SAME! How can shifting the exposure work in DEP mode? It can't!
