abstract:In the subfield of abstract algebra known as module theory, a right R module M is called a balanced module (or is said to have the double centralizer property) if every endomorphism of the abelian group M which commutes with all R-endomorphisms of M is given by multiplication by a ring element. Explicitly, for any additive endomorphism f, if fg = gf for every R endomorphism g, then there exists an r in R such that f(x) = xr for all x in M.
We were able to go hands-on with both models -- they feel much more solid than Sony's less-equipped Handycams, such as the CX380 and PJ380, likely due in no small part to the large Balanced Optical SteadyShot module at the cameras' core.
Both include Balanced Optical SteadyShot, which moves the entire lens module (not just specific elements) for much more effective stabilization, especially when zoomed in.
