Can you quantify that? I mean, how much softer and under what circumstances. How noticeable is this going to be say, under full-auto?
It's difficult to quantify precisely, but just something that I've noticed over time, correlated by observances of others elsewhere, backed up by scientific principles. Yeah it's not going to be huge like Jimmy mentioned. But shoot a D80 and a D40 back to back a lot like I've been and you start to notice the subtle differences. But mainly I like the cleaner high ISO noise and better dynamic range of the 6MP sensor. You notice that first. The subtle sharpness differences between the 6MP and 10MP is something you have to go digging around a bit to see. In normal sized prints you'd probably never see it.

Small-format DX and 1.6x DSLRs were ideal for digital SLRs up to about 6MP back in the dawn of digital photography. By about 10 MP in small formats, most of the extra pixels today are splitting up the limitations of your lenses (and our own photo abilities) into smaller pieces instead of showing us more detail. Having more pixels on a small format doesn't make a sharper picture if all these extra pixels are doing is splitting up a lens' limited resolution (or subject motion or limited depth of field or small-aperture diffraction) into more pixels.
So then you might wonder how 8/10/12 MP little pocket cameras are working. They have the same problems, only worse. I've looked at some full-sized image samples of some of these ultra-high MP P&S's out there today, and they're far worse than anything that comes out of my DSLRs.
I know it's counter-intuitive, but sometimes less really is more.
here's another good article to read:
The Megapixel Myth
Sorta like how I wanted a quicker car, so I got rid of one with 200 bhp in exchange for one with 190 bhp.
huh? 
Yeah,
less power to go faster. :mrgreen: The one with less power had a superior powerband (way more torque over a broader range), 300 lbs less weight to drag around, much better gearing, a more efficient manual vs a lossier automatic, and would run circles (literally) around the "more powerful" one. I took a lot of these things for granted with the first car, but not with the second. Overcranked megapixels in cameras is sorta the same. You're getting more, but is it
really more? No, not really in a lot of cases.
I'm on the fence as well, between some of the Nikon DSLRs.
Thanks Mav...I appreciate your input as well as you other regulars':hug::.
you're welcome!
