Mu understanding was that these 24?MP sensors do not yield to as much PP as earlier models, that pulling detail out of the shadow would not be as effective on a D7100 and D610 as on a D90, despite other obvious technical advantages of those cameras. I'm told the files degrade much more quickly than on D90 so if you're relying on a lot of PP, stay where you are.The ability to lift detail out of the shadows is worth the upgrade alone in my opinion. The autofocus is more accurate for moving subjects. Higher ISO shooting, cleaner files, more detail. There is nothing wrong with the D90, I used mine for years & still own it. But there is a noticeable difference in what each can produce.Thx for the replies. If there is no big impact the I don't see a need to through away any money. It would just be for the sake of having full frame and updated gear. I also believe that composition is the key component of photography, but many times I feel like my photos could be little sharper. When i do look at photos at different magazines or from popular photographers on many website, I am amazed of how sharp they are. I only use light room for the post processing and maybe that is just not enough or maybe I am not good enough in post processing or shooting technique. But in general with 50mm f/1.4 prime and 55-200mm f/4 I get the most satisfying photos.
