X sync and M sync on my Rolleicord - please explain

I bought myself a Rolleicord and have got it all figured out except

for the X sync and M sync settings for flash photography. I am

probably showing my lack of formal photo education here, but can

someone please explain the difference?

 

I have been using my Nikon flash with it, metered manually and sync'd

at 1/60 in the X position, with good results. Haven't tried the M

position yet.

 

Thanks.

I think the M position is for flash bulbs, which have a longer delay and burn time. If X position works, use it.

The previous answer is correct. If you shoot with electronic flash on the "M" setting your images will not show any flash exposure. M synch allws a slight delay to alow the slower burning bulbs to reach peak brightness.

Hi Robert,

 

The X sync is indeed correct for electronic flash, zero delay.

The M sync is for using flashbulbs, which you are not likely to use in this day and age...depending on the type they can be quite expensive. M sync is used with so-called class "M" bulbs like GE #5 or Sylvania Press 25 or Press 40. These bulbs require a 20-millisecond shutter delay as this is the amount of time they need to reach their peak flash output. If you are interested in trying flashbulbs out some time then the way to go is to get a Graflite 2-cell battery case, some #5 bulbs, and a Household-to-PC sync cord. I think the flash output is greater than what you will find in most electronic flash units. With a sufficiently stopped down shutter (based on the bulb guide#) a flashbulb used with the Rolleicord will produce an outstanding tack-sharp image.

Hi Robert,

 

The other answers are correct but don't limit yourself to shooting at

1/60th second shutter speed. Your Rolleicord will sync (with

electronic flash) at all shutter speeds.

 

This ability makes the camera much more versatile as compared to

cameras with focal plane shutters.

 

Enjoy.
