comment How to take a photo of a close-up object without focus stacking?
Right, small sensors have a lower diffraction limit which is why most compacts max out at F/8. Some have slightly larger sensors and offer F/11 which maintains sharpness reasonably.

comment Adjust exposure compensation in manual mode?
It it only adjusts the displayed meter and does not actually change exposure, which is one reason why this can be confusing.

comment Are there cameras that autofocus during an exposure?
With exception to the Canon EOS 70D, they use Contrast-Detect AF which can easily be detected by the back and forth movement of the lens when out-of-focus. The camera measures contrast and moves the lens to see if it increases. If it decreases, it starts moving the lens the other way. Sony SLT cameras were designed exactly to avoid that problem. Canon fitted the 70D with phase-detection at every pixel so it can continuously adjust focus while filming. For video, one should really focus manually because any misfocus, including locking focus on the wrong subject, will be visible in the film.

comment Are Manfrotto Q6 Plates Compatible with Acratech GP-ss Ball-Heads?
@DanWolfgang - Sounds like you know more about this! There is no information saying that the plates and clamps are not designed to be interchangeable, which is easy to imply by how they are named. Perhaps you can contribute details as an answer?

comment Is the Gorillapod sturdy enough for super-zoom lens and long exposure?
That's a tough question because I own 5 cameras and am constantly rolling through review units! Overall, the Gorillapod works extremely well with Ultra-Zoom Bridge Cameras and Mirrorless with medium-sized lens. For a DSLR, my lenses are mostly too big to get good stability, even with the SLR-Zoom.

comment How many stops are there between middle gray and white point?
Not only this varies by camera (otherwise they would all have the same DR), it also varies by setting (Contrast, Tone, etc). So I'm going to say impossible to answer.

comment Why is the field of view of my lens narrower than my calculations show it should be?
The focal-length varies with focus and is usually quoted with focus at infinity. Try changing focus. Also, are you measuring the height from the sensor-plane?

comment Why does Nikon D3100 makes occasionallly noise and viewfinder shifts when pressing shutter button
Try disabling stabilization on the lens to see if that is the source. It's the only thing than can shift your view through the OVF.
