For years, I pined for the quality of my previous 4x5 work in digital and celebrated the day when I finally purchased at D800E. I love the quality, the detail, the DR! But, alas, it's a lot of equipment to carry around when on the move travelling, so...
I am foregoing quality for the convenience of having a "walk about" camera. In one sense, I feel treasonous, but am reminded that the best camera is the one in hand. I figure, if I'm hand-holding my D800E with a walk-about zoom, then I'm not getting the full IQ anyway.
Here's hoping the 1" sensor will meet my minimum standards of IQ for prints and books. From the testing I've done, I believe so. I also need to remind myself that I have three wonderful 16x20s shot with a 5mp Minolta Dimage 7i hanging in my home, plus one shot with a 5mp E-1 and another with a 12mp E-30.
My more serious personal work will still be done on a tripod with the DSLR, so it will be like going back to my 4x5 days with the 35mm gear for the less serious work.
Maybe this is just part of the future as technology and software progress.
