Re: Same Focal Length / NOT same angle of view ?? Panasonic 14mm, Olympus 12-40

Looks to me like one of them isn't really at 14mm. This usually occurs on zooms much more than primes (almost unheard of afaik), and especially digital zooms with no lens barrel FL indication, as the internal electromechanical sensor that states what position the lens is actually at can be improperly or poorly calibrated, and thus read erroneously. There was recently a thread about such a lens that was off a few mm on the short end.
