Just some dragons and their cousins,

Although I don't have posted much lately some post's about high speed sync
and comparisons between P,C,N made me look into what I could get out of
my sigma500ex super.

It has a high speed sync mode (fp) but I had not used it till now, and now
I'm sure I'll be using it a lot more.

starting of without fp
(high speed sync) - I can't remember if it was active or not
but at 1/180 it doesn't count.

Camera Model: PENTAX K20D
Image Date: 2008:10:06 15:29:08
Flash Used: Yes (Manual)
Focal Length: 280.0mm (35mm equivalent: 420mm)
Exposure Time: 0.0056 s (1/180)
Aperture: f/5.6
ISO equiv: 100
White Balance: Auto
Metering Mode: Center Weight
Exposure: aperture priority (semi-auto)



Then overdoing the iso setting a bit (iso 1600 and f 9.5 weren't really needed)

Camera Model: PENTAX K20D
Image Date: 2008:10:06 15:42:34
Flash Used: Yes (Manual)
Focal Length: 300.0mm (35mm equivalent: 450mm)
Exposure Time: 0.0029 s (1/350)
Aperture: f/9.5
ISO equiv: 1600
White Balance: Auto
Metering Mode: Center Weight



And at last getting where I wanted to be.

Camera Model: PENTAX K20D
Image Date: 2008:10:06 15:56:02
Flash Used: Yes (Manual)
Focal Length: 300.0mm (35mm equivalent: 450mm)
Exposure Time: 0.0013 s (1/750)
Aperture: f/8.0
ISO equiv: 560
White Balance: Auto
Metering Mode: Center Weight



I'm still not shure why the flash settings are displayed as Manual in the exif
while they where p_ttl and fp.

So my thanks to everyone who posted about the high speed sync because
for whatever reason they started posting they put me on the track to use it.

Ronny

(ps forgot the lens - sigma ex 100-300mm f4)

I like the last one because of the color and the composition. An amazing close up of some very skittish creatures. Auto or manual focus?

All are impressive pictures! This talk of flash capabilities shows me just how little I know about flash. I've got spend some time playing with it, what everyone else is coming up with is phenomenal!

Thanks Glenn,

manual focus, autofocus just won't keep up with them. But when they are laying their eggs they hover multiple times above the same spot (not 100% the same place) and then it becomes easier to focus.

Thanks Harriet,

I'm still getting to grips with the way a flash works but imho its worth the effort.

Very impressive as usual Ronny.



When using the FP mode, what mode were you using on the camera.

I haven't tried it on my K20D, but on the K10D I could not go above 1/180 in manual mode. I could only achieve FP in auto modes - AV or P, not M or TS

Thanks Dal,

just tried out all settings to be sure and the K20d doesn't give any problems with any mode.
Although when using M the exposure meter stays way down and it doesn't help to get the correct exposure.

Another thing that I didn't knew when I took the shots above is that when you use iso auto setting the camera seems to prefer the highest iso setting available. Hence the iso1600 in the second shot.
