I must disagree, I'd like to thank you very much for mentioning it

I was a little uneasy about the prospect of the Sigma, and the Pentax is just too much money.

So now I have a realistic prospect of being able to afford a very well-specified gun, so I'm very grateful.

I'm of exactly the same mind.

I'm working hard on myself, trying to justify finding the money for the Samsung.

So far, I've got:

- the built in flash simply doesn't cut the mustard
- I want wireless
- I've only got a couple of old manual guns
- the Samsung 54 is almost certainly the same as the Pentax 540, and I'm not at all interested in the badge if that's the case
- I've spent a bloody fortune in the last 6 months on camera gear, what's another £250 or so (including the off-camera bits we were talking about earlier) ... poverty is poverty

Any more good reasons to go for it, to push me over the edge?

{Sigh}... yes I was afraid it might be expensive.

Thanks for that.

The SEF-54PZF and the AF-540 FGZ are both 380g in weight, excluding batteries.

A bit of a coincidence if they're different inside.

On another note, a bit of a noob question if you'll forgive me... what extra bits would I need with either of these to mount the gun on a hammerhead? It weighs nearly a pound, so it would be nice to be able to have it off the camera.

If they really are identical to the AF360 and AF540 (and therefore fully compatible with the K10D, and provide all the cool features that the Pentax guns do), then I'll get the 54.

I won't be paying an extra £150 for a Pentax badge just for a flashgun. But the £30 more than the Sigma gun (EF-500 DG Super) probably is worth paying for what I'd guess to be slightly better build quality and compatibility.

That's even better news.

(and, incidentally, I was referring to my own assumptions/hopes about compatibility as having the holes, not anyone else's).

But the camera is, isn't it? So if the flash can talk to the GX10, it should be able to talk to the K10D.

I know... more holes than Swiss cheese.

Wow. At that price it's very tempting. Only about £30 quid more than the Sigma, and presumably less risky in terms of compatibility (?)

I'll be very interested to hear your impressions of the build quality.

I'll be after the Super, probably, since I want wireless, and I can't justify stretching to the Pentax AF540.
