Graham I looked at your other post. I agree that the Oly OM-D is not a relacemaent for a Nikon DSLR, either DX or FX. It makes a good, compact, light, and pretty capable travel camera. For more serious shooting, I would choose my D300 or maybe my D90. I find the Nikons much faster to adjust, but that is because I have used them for a long time and I am having a hard time mastering the Oly operating controls and menus. I even bought the the hard copy of the manual, but maybe I am just one of those people who has a hard time adjusting to something that has similar capabilities to an existing item but impliments them in a very different manner. There are times when the Oly is so frustrating that I consider selling it!
