In the old days when camera bodies were all metal, the bodies were more resonant. They would ring like a bell or vibrate. Today's camera are built differently and not as resonant. So is shutter or camera vibration still a really big issue? In the recent tripod thread I saw a few mentioned dampening vibration with carbon fiber. How valid is this today?
I see posts about prime is sharper than zooms. There are some really sharp zooms out there today which are better than the zooms of the past.
I see posts about not using hi ISO or going over a certain ISO. Today's cameras perform much better at higher ISO's.
On the other hand if you're a purist, I guess these issues can be very significant or if you still have older equipment. It also depends on how much of a purist one is. If that's the case, a purist should always be on a carbon fiber tripod, only use prime lenses, and never go past ISO 800 etc. I can understand striving for the best result but how far can one go and how practical is it?

It's not the resonance in the camera body that causes vibration. It's the moving mirror and shutter. If you google shutter shock or vibration you will see a lot of good info, even pertaining to some mirrorless cameras like the Sony A7:

Don't expect a $200 tripod and head combo to be anywhere as stable as a proper tripod. There are many myths that need to be put to rest - a tripod needs to have 2x the load capacity of your gear, a heavy tripod is better than a light one, there is no difference between aluminum and carbon, and the best one I heard yet - if the tripod can support bowling ball, it should be good enough.
There zooms that are as sharp as primes and vice versa. Broad generalizations ought to be ignored. Old zooms were, as you have observed, often not as sharp as the new stuff.
The overall goal for sharp, clear, high quality images is to use the lowest ISO, fastest shutter speed, and the sharpest aperture. For many lenses the sharpest aperture is often 2- 3 stops from wide open. Some lenses, like long telephoto primes, are often sharpest at maximum aperture. Exceptions to the above goals are often made for creative interpretation - like using a slow shutter speed combined with flawless panning technique to show movement, or using a large aperture to isolate the subject with shallow depth of field, or a tiny aperture to have deep DoF.
For pros, the deciding factor is the client, who will demand a specific level of quality. Typically a pro will be able to justify the best quality gear, including a support system (or any other component) that will not fail at a critical moment. Anyone who desires that high level of quality will either buy the best gear, or do the necessary homework to find suitable substitutes, usually keeping an eye on budget.
And for the naysayers that claim they have never had shutter shock or mirror vibration, please describe the gear, setup, technique, and post a result.
