Less likely to have FP or M sync for flashbulbs, which I bet is one of
Indeed I was :-). As I said, somewhat tongue-in-cheek.

Flash sync - sure, that is pretty much standard. the things what Tony was thinking of, and in fact I
don't think I've
seen that on a DSLR. But then, modern DSLRs are designed to be used
with modern electronic flash, not bulbs, which are fairly hard to find
This does not suprise me, and relaisitcally on the few times I use flash
equipment, I do use gas-disharge flash, for obvious reasons.
now. Ditto for a lot of reasonably modern (last few
decades) film
cameras, actually.
Of course you van use flashbulbs on X sync provided you set slow enough
shutter speed for the bulb to have ignited before the shutter closes .A
lot of cmears with X-sync only tell you to set a speed of 1/30s or so.
Then there are cameras, often leaf-shuttered (Compur, Prestor, etc) where
you have choice of M or X xync, but if you want th self timer you have
to select X sync. For a good reason/ The same escapement is used both for
the self trimer delay and the sync delay in M sync mode.
More of a problem are old cemaras with M sync only (yes, thye do exist, I
am handling one right now, a VP Exakta). You can't use electornci flash
ith those at _any_ speed, the cotnats will have closed afd fired the
flash before the sutter is open. I am considering making an electronic
delay unit to conteract the inbuilt sync delay.
