Re: Interesting discussion of flash sync speeds at Strobist.
Last year I gave my Olympus the test that this site suggests.
Nominally, the synch speed is 1/180sec, and I found that to be correct
at full power with a Metz 60CT-1. Any higher and I'd see a very
diffused shaded band, not objectionable or even noticeable at 1/200sec
with a normal scene. With a Metz 32CT-7 I could safely use 1/300sec.
But experience tells me that big floor pack like the Hensel 3200 joule
and 6000 joule units that I once used could show a shaded edge even at
1/125sec.

Re: Interesting discussion of flash sync speeds at Strobist.
I think that article was quite confusing.
The nominal sync time of a camera refers to the speed of the shutter
lamellae, doesn't it? The quicker the movement, the shorter the
interval can be for a fully opened shutter. The article describes the
_practical_ sync time which should also depend on how well the camera
synchronise the shutter and the flash blink. Many of the commenters
point out that it works at 1/200 when the flash is mounted in the
hotshoe, but not when off-camera. So to me it seems that Canon has a
sloppy implementation of sync speed rather than an unreliable shutter.
Maybe it's the flash that's sluggish rather than the camera?
Anyway, I'm quite happy with the way flash is controlled in K-7. The
hi-speed sync works fine with both the AF-540-FGZ and Metz AF-58 when
1/180 is not enough. If I absolutely had to pop a flash at high
shutter speeds as if working with conventional sync speed, I guess I'd
go manual and be done with it. I don't see the need for the article's
hype, really. Maybe I've missed something. :-)

RE: Interesting discussion of flash sync speeds at Strobist.
From: P. J. Alling There was a certian amount of Angst about the K-7 having a sync speed of only 1/180 sec. Well at least Pentax seems to be honest... http://strobist.blogspot.com/2010/01/know-your-sync.html Os so it seems to me. The last part about Crank the Volume to 11 won't work with Pentax, will it? The hot-shoe won't fire the strobe at greater than sync speeds, except for the high-speed sync mode on the AF-360FGZ or AF-540FGZ (which I haven't figured out yet). Just tested the K10D (1/180 or less) and *ist-D (1/150 or less) with a dumb flash Vivitar 285HV and neither will fire the strobe at greater than sync speed. I also tested the *ist-D using the PC sync, and it doesn't fire that at greater than sync speed either. It's a good article though. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
