I will try with an external flash.
Sorry, you will have the same metering problem with an external flash.
If the external flash has some manual power controls, like 1/2, 1/4, 1/8, 1/6, etc,, then you will have better control. But you still have to do some manual calculations, or trial and error.
If the external flash has an auto thyristor mode, then you might be in more luck. However, few flashes that I know of support a thryristor setting corresponding to an aperture as wide open as f1.7, which you said you were chasing. (In auto thyristor mode, you do have to initially "sync" the camera's aperture with what the flash thinks is being used, and f/1.7 probably won't be within the flash's range.)
