I really haven't taken the time to delve into the 7D and don't have one.
I wonder if someone has actually published some research into this camera/sensor in a definitive way that lays out the proper approach to things such as "input sharpening"?
For example, by nature, some input sharpening would be required with a Raw image in a Raw processor simply to compensate for the physical softening caused by the antialiasing filter. That's always been a "fact of life" with digital images, and this is why sharpening is typically applied at various strengths when you shoot jpegs (unless you purposefully crank it way down manually in the camera.
So the above poster who called sharpening incorrect was, well, not entirely correct. But it is true that the camera should not require dramatic sharpening just to lookd acceptable, just the right amount to recover from the filter softening and bring out the proper fine detail.
So, how much is the "proper" amount for "input sharpening"? It does vary from sensor to sensor, and on the 7D I suspect that it is at a higher level than most if not all previous sensors, but how much is the "right" amount? This should not vary with the lens, although certainly the fact that if you get a soft image it will in itself require special attention, but let's say you had the sharpest lens and you got the best possible focus -- how much "input sharpening" would be called for?
I'd be curious to see if there are any published studies. This camera/sensor presents its own little challenges, and this is one of them. To know whether a shot from a particular lens is "soft" you want to have a base "starting point" and if that was clearly understood with the 7D it would help users in their evaluation.
Of course, shooting technique plays a major role in these things, and more so with the 7D than older cameras simply because the high resolution of the 7D will bring out any errors in technique "larger" if viewing an image at 100%. So really, someone asking about a "soft" image at a 100% view should first of all identify whether it was shot hand-held or not, and if so at the very least a quite high shutter speed that will ensure that camera movement will not be an issue, and in this case I'd say the shutter speed should not be defined by the "rule of thumb" of 1/flxcrop factor but significantly faster. Otherwise, the likelihood of camera shake being magnified by the 100% view is way too high. And, it goes without saying, that further testing needs to be done with a tripod, MLU and a remote release/cable release so you can get a good starting point/reference to truly evaluate things!
