While AA Lithium and AA Alkaline disposables claim a nominal 1.5V each -- so what it comes down to is whether AA rechargeables are intended to replace proprietary rechargeables (no advantage IMO) or whether AAs (in particular disposable AAs) are intended as emergency power-sources only.AA rechargeables have 1,2V.

Hey, I did check into this before forking out the cash ;-)There are schemes of optical slaves, compatible with preflash.
Also You can use combination of these:

Quote from your 2nd link - "It transfers only the "trigger" and "ready" flash signals" about the MV1...The five p cabling and shoes coupled with one of these should do
it, shouldn't it?? As long as the Bowens can count by 2 and ignore
the first pulse..... Flash is not my strong point, not sure I have
a strong point, but seems technically feasable. Petty sure they can
be stacked as well, some are/were 2 ports (L and R). They were
built mostly for the 645 I think and there would be a hotshoe grip
to go along with it.

That depends which part of it you read.The press release says no support for powerzoom.Unsure:
- Hello (long time since) PowerZoom (due to the USM connectors)?
AFAIK, the difference is much less than that.4 AA's or a rechargeable battery half the weight,
You know, now that Pentax has decided to use evil proprietary batteries, I could just ignore that stuff. But with 40'000 shots with NiMH on my DS, I just can't help but still be amazed at those comments.I know what I
would prefer. From my own experience when playing with the DL2 and
K100D, unless your batteries are fully charged you get significant
AF and shutter lag.
Faster than my NiMH charger? Show me.Sorry, I would prefer proprietry batteries any time. Consistent
performance from fast charging
So, what batteries do you use in your flashes?and supported rechargeable
batteries, that is what a pro needs more than the availability in
the field of AA's in the stores which slow the camera down.
1000 frames a day is not much - I have no problems doing this with AAs. Not just pros need charged batteries. Being "fully charged" is not unique to proprietary batteries. Biggest advantage is that you can change one battery faster than four. But there would have been solutions for that.Of course I write this as a pro who will easily use 1000 frames
shooting a wedding and needs to know that he has fully charged
batteries always at hand.
There's a certain truth in that. Too many people using their Pentax dSLRs with bad chargers and/or bad batteries ruined the reputation of NiMH AAs. That won't happen with proprietary batteries and chargers. I'm sure we all gladly pay extra for that luxury. Not!though they are still not rechargeable. I think Pentax is welcoming
the pro market with this camera and is therefore having to work the
way pros are working, rechargeable, small and consistently
performing proprietry batteries.
There are optical slave triggers that can deal with preflash. I'm not talking about Wein stuff, check the Metz 3083, if you haven't.up the foreground. Because of the preflash you have to use a radio
slave, optical slaves won't work.
I'm assuming it will talk to any USB Host device, including portable devices such as iPod Photo.Does that mean I can't connect it directly via a USB cable to a
mobile HD storage device? That would suck on travels.
Li-Ion batteries defrade continuously from the day they are made. It doesn't matter whether you use them/don't use them/store them properly/store them improperly, the will fail to hold a charge properly in about a year, or so......... and good riddance.
I bought the *istD BECAUSE of its use of AA batteries but to be
honest, in spite of using branded high quality batteries I have
felt shackled by their unreliability and inability to hold a charge.
The modern Dslr sips electricity and rarely will you run out of
charge. However, the self-drain characteristics of AA NiMH's have
been a constant pain compared with the
Nikon/Canon/Olympus/Sony/Minolta BP511 type of battery. Dunno why
to be honest - but AA's are off my list in future cameras.
PS - I never did find myself in some remote village for a week
where I couldn't recharge my battery and my only hope was some
spare AA alkalines. Shucks.
AA Lithiums (non rechargable) worked extremely well for me both power and weight wise...
- Goodbye AA batteries
I have to admit I do not know how your studio strobes are designed, but I know that the power of the flash is not directly relevant for it's trigger (look up transistor flash to see what I mean) and I know that "Watt" is not a suitable unit to measure flash strength. "Watt seconds" would be more appropriate.As for the Metz digi adaptor, I'm trying to fire 500 watt strobes
here not weeny hotshoe flashes.
That's right.The slave only works with Metz units anyway.
Well, the TTL ones, yes. As I understand, you couple remote TTL flashes with remote x-sync flashes. This is indeed a tricky combinationWireless flash systems use multiple preflashes right?
I don't use them often, so take this with a cup of salt, but within their design limits I found them to work very well.Pro's have told me that these digital optical
slaves are unreliable and inconsistent in the field as I've
mentioned.
I found no discernible difference between my AAs and my CRV3s. But AF performance isn't my main interest, so I may be wrong.take my own batteries. So next time I went with NiMH's of my own
and tried them and they were right, the lag was there but far
better. I asked again (here I think) and was told that I should use
CR-V3 's for the best performance and least lag.
Not really, but just as I won't change your mind, you won't change mine. If I were in your situation, namely shooting in a controllable environment and having the amount of gear you have, a charger or two more or less won't kill ya. When I'm travelling, I'm happy to carry only my small AA charger and fill the bag with another lens.You see why I prefer the idea of proprietry batteries?
You know, I am not really pro-AA, I am pro interchangeability. If every camera and flash would use the same type of LiIon, I'd be 100% pro LiIon. Wouldn't it be nice if you could use the same LiIon battery in your flashes as in your camera?You ask if I would like 3 chargers. I'll be honest, I have two
rapid AA chargers and I could do with 4. I use two flashes and my
battery pack carries 8 more AA's. All need to be charged after a
wedding in time for the next days shooting. Do I really want to
have to charge another two sets of AA's each time? I think not.
