Flash unit display wrong numbers here is something very puzzling when I have the DF-483-CAN vivitar series 1 flash at the 90 degree angle front facing; it's supposed to know my ISO, shutter, and fstop. when I change my ISO it syncs good. However for my f/stop it displays the wrong number: camera flash unit f/2.8 f/2.8 f/3.2 f/2.8 f/3.5 f/5.6 f/4 f/4 f/4.5 f/4 f/5 f/5.6 f/5.6 f/5.6 f/6.3 f/5.6 f/7.1 f/8 f/8 f/8 f/9 f/8 f/10 to f/22 f/11 Anyone know why this discrepancy happens/how to fix it?

Bouncing the flash will cost a stop oflight or thereabouts.

?? I'm not talking about bouncing the flash, just talking about the displaying of the f/stop number on the back of the LCD flash. It doesn't match the camera LCD.

Looks like your flash can't set to the "in-between" f/stops. Think of how a ruler is marked for 1/8 inch, 1/4 inch, but the only numbers on the ruler are whole inches, 1,2,3,.. Now f/stops are displayed on the camera lcd screen, but track down a lens that had f/stops written on the barrel, you could set it to f/6.3, f/7.1, but the only numbers written would be f/5.6, f/8, f/11. Those are like the whole inches and f/6.3 is like 1&1/4 inches. So your flash doesn't set to those, it just jumps when the camera gets on a regular f/stop. Or maybe it can but doesn't display. I'm guessing that it doesn't set and it's depending on the latitude. Is that an older model flash that was made when it was film over digital? If so the latitude of film or the photo lab would compensate for the difference in what the camera was set to.

I'm pretty sure the flash model is new as of 2011. That makes perfect sense Gregory, thanks.

Under more common circumstances f/22 with a flash is going to be really close to something or using a more powerful studio flash, something plugged in to a power pack. You're probably on an auto setting and it just won't go up to f/22. With a hot shoe flash, even full power your distance is going to be 3.5-4 meters. And that's iso 400. That's going by the scale on my flash. And it's got pretty good power. So you don't have anything to worry about. It's not usual shooting that requires f/22 with a hot shoe flash at your typical shooting distances. Auto settings are mainly designed for those typical situations that don't go too far to either side of f/5.6, shooting distances the size of a typical family room. Not a full power blast to get to f/22.
