Perhaps it can be understood that H-PS 14042 is the lens name, LUMIX G? Xvario pz14-42mm f3.5-5.6 asph powerois This group of characters is the introduction of the camera. LUMIX Panasonic lens LOGO, G is probably G series? Vario is a zoom lens. What do you mean by PZ? I don't know. OIS seems to be some kind of optical anti-shake technology. Anyway, every space is separated by a technical name or a trademark name.
