second leaf sync. 430ez flash

[petewood]

this ones simple if you know it.
I've forgotten how to sync my flash (speedlite 430ez) with the second leaf at the end of my exposure. It's a slightly older, uk baught model so I'm having difficulty finding a manual to download.
thanks if you know it!

What kind of film camera are you using this on?

Been using an eos 5 and loved it.
Just baught a eos 20D

I'm from england where my kit was baught.
is the 2nd leaf control on the camera not the flash?

[petewood]

is it going to be possible for me to use this function with the new digital body?
thanks

custom function 15 on your 20D is "second curtain sync".

[petewood]

Thankyou!
thaught I was going crazy!

Are you sure that flash is going to work on your 20D? If it does, it'll only work with the flash in full-power manual mode. No ETTL nor ETTL-II.

I agree with Leo. XXX-EZ flashes are not intended for EOS digital cameras, since they do not do a pre-flash that digitals require for normal modes. For a 20D, you want any XXX-EX flash.

nuts!!!!!!!!!
Oh well.
the 20d hasn't actually arived yet, in the post. sure I'll get the hang of it, anybody want to buy a 430 ez?
what about the canon 75-300 IS USM, any reason why that won't talk to the 20d?

you can still use your flash in manual mode. That lens should be just fine (you're okay as long as it EF or EFs mount)

I don't think he's going to want to use that flash in manual mode. Unlike the ETTL flashes that have spoiled us, using a non-ETTL flash in manual mode is not a simple matter of just setting the aperture and shutter speed to whatever values one fancis and expecting to get a properly exposed picture. Using a flash full power in manual mode means that the aperture has to be determined based on the distance of the subject from the flash. That involves doing some on-the-spot math taking into consideration the flash guide number, the subject distance and the ISO being used. Or using a distance-aperture by ISO table that's been created ahead of time.

I'm doing it all the time. Fun!

IIRC you're using a Vivitar 285 which has an auto-thyristor to control the flash based on the zone you're in. Unless you're using it at full power and computing the aperture for every shot based on exact distance, it isn't the same.
