After playing with D7000 for a few weeks, I found that D7000 needs faster shutter speed to counter hand shakes comparing with D300 or D5000.

The old rule of thumb is: Shutter speed = 1/focal length.

Some say for DX camera it's modified as: Shutter speed = 1/ (F.L. * 1.5) This is actually taking into account sensor pixel density, not much to do with DX or FX. If we take a picture at the same focal lengh with a D3X (24MP) and a D300(12MP), the D300 picture is roughly the crop of D3X picture, the rule for the shutter speed should be the same. Therefore, it's about pixel density, not format.

In the same spirit, the increase pixel density of D7000 will have effect on this rule of thumb. The line magnification of D7000 vs D300 is about 115%. If you need shutter speed 1/(F.L. * 1.5)on a D300, you will need 1/(F.L. * 1.75) on a D7000.

On D7000,
at 50mm, you'll probably need 1/85"
at 70mm, you'll probably need 1/125"

I guess this maybe the very reason behind some "not sharp" complaints out there about D7000.

Well, this is far from anything scientific, just that as the pixel density increases, the rule of thumb might need to be revised too.

What do you think?
