Someone out there will know more than me, but I don't think the sigma will work in wireless with the camera or 360FGZ, simply because to my knowledge it wont work in P-TTL mode which requires a pre-flash...this pre-flash to my understanding will set off the sigma before the exposure flash. A) this will completely confuse the cameras metering, B) the flash will not charge again quick enough for the 2nd fire.
That's just my thoughts for what they're worth.
I haven't used the *istDs, just the *istD. Also, yes I'm 100% sure the 360 will shoot wireless on it's own (2 are not required).
Hope this helps.

The stupid thing is that in buying my 360 FGZ I knew it was the most compatible for the *istD but the 500FTZ had more power and a swivel head so I couldn't have the best or "ideal" unit - they never make it that easy

I noticed you're thinkng of selling the Z1. I'm getting my wife into photography and wondered what you want for it and if you'd ship it to Australia?? I want her to have a decent camera she wont grow out of too soon.

Thanks, Phil.

Let's just say first that I have used the K1000, P30, ME Super, MZ-50, MZ5n, *istD, P645.

Of them all, I of course loved the P645 and would love to get one. In terms of clever thinking I think my *istD tops them all. In terms of robustness, I threw my P30 10 Metres once, and it went underwater very quickly once too...and it's still going strong. It's my camera for daring and stupid photography spots!

...I ON THE OTHER HAND LOVE MY 360!

should have bought it ages ago. Wireless means you can shoot with it off the camera up to 1/4000 sec. It is compatible with the MZs, *istD and *ist cameras. Not sure about the *istDs.

I made a diffuser for mine similar to the Stofen Omnibounce. Below is an image showing the difference between a shot with normal flash mounted on the camera and using wireless with the diffuser on. I just shot a wedding almost entirely using wireless flash and the results were fantastic.

here's the link: http://www.philtaylorphotography.com/ONP/diffuser.jpg

As for not having enough light, I shot with this up to about 10 metres away with good results. For anything past 15 metres I would shoot without the diffuser (this is all at ISO200). For those images I was still very happy.

Good luck. I used all sorts of other brand flases for years because they were cheaper. I finally bought the genuine Pentax and it's been going strong for a long tme now. The others were very unreliable. Let alone not as compatible.

Sorry, just realised you are using the MZ-3. The flash works well on my MZ5n which I assume will be similar. Beautiful light everytime.

While I'm at it, do you need any compensation due to the loss of light through the omnibounce?

I've just ordered my 360FGZ and wondered does it allow high speed sync with the *istD or just the MZs and *ist? Anything I should know straight away before I use it?

Thanks for the reply Malcolm, at least I know it's not just me. Hopefully they could fix this with another firmware update. Hopefully not a hardware problem.

Every time I go to download my images to my PC, once I turn the camera on (with USB cable attached), the battery depleted message comes up and the camera turns off. When I disconnect the battery pack, I have no worries but it's a real pain in the neck!

Has anyone else had this problem? I've only noticed it really since installing firmware 1.1 but it may have happened a few times before, come to think of it.

Any help greatly appreciated.

P.S. sorry, should have mentioned, it doesn't matter if the pack is turned on or not.

I can't help you with your question and I assume you now know the answer...I also have the *istD and have just ordered my 360 FGZ and wondered what your results were like (as I will occasionally be using it with my MZ-5n which I assume wont use a preflash.
