That would make it F11. This is likely the reason that the 200-500 is listed in the chart as not AF compatible with this converter. This chart lists only DSLR cameras in exceptions, but I doubt the Z50ii will autofocus with an F11 lens. Not sure what you are looking to do with this lens, but 500mm on a crop frame camera with a 2x converter will give you an effective 1500mm focal length. That is a rather long tele. Without the converter it is effectively 750mm and no loss of light.</p></blockquote><p></p>
