Can anyone here confirm that this applies to mirrorless cameras? I'm assuming it does, but not knowing the technical aspects of how the metering works in my GH4, I just want to make sure.

According to Panasonic UK, you should use a circular polarizer, but I admit I don’t understand why:

New linear polarizers are fairly scarce — there are only a couple of odd corner cases where a linear polarizer is preferred.  With a more expensive polarizer, what you are paying for is the name, coatings, sometimes high transmission polarizering film, sometimes “encasing” (Kaesemann), sometimes brass hardware, and general fit and finish.

A multicoated filter will transmit about 7-8% more light than an uncoated filter.  Uncoated filters are also more likely to cause flare.  I own polarizers in a lot of sizes, and most are multicoated.
