Difference between a Canon and a Nikon crop sensor
Most, if not, all Nikon have a crop factor of 1.5, while a Canon has 1.6, does this mean that Nikons are closer to a full-frame, in terms of having a bigger sensor and all the benefits that comes with it?

If raising the center column makes tripods unstable, why can they be raised so high?
My question is about the center column height on tripods. If it is so unstable, as it is described in many websites/forums, then why do manufacturers add it to tripods?
My question may sound naive, but I like learning this kind of details.

I use Lightroom (5.2) for post-processing, which can also correct lens-aberration.
