No upgrade in flash on K3?

Anyone knows if there is any retouch in the flash system? Is max sync speed is 180? Built-in wireless? revised chip to solve the problem of inaccuracy of bouncing flash?
-- Flash was a limit factor on all earlier models.
A very lovely camera. But I would like it more if it has new flash, and if it has a "new" 16 mp sensor with much better high ISO behavior instead of 24 mp. But that is the market. None else likes 16 mp anymore .

The flash is the only thing that wasn't touched. As for the sensor, you should still see a marginal improvement in terms of noise (24mp scaled to 16 mp = less noisy), but it's close to the current limits of the APS-C format.

I ment the chip controls the flash (I am sure it is part of the whole board, but don't know what to call that part). Bounce flash on K5 was a problem, as many of us experienced. Don't if it is the camera or flash to blame to. Maybe someone can report back here, with new combo of K3+ NEW flash.
in terms of imagine sensor, i am sure of pentax spent the effort they put on the new 24 mp sensor on a 16 mp one, the high ISO noise level should be better controlled. but, as I said, I understand pentax had to add some numbers there.

New metering chip.

Yes.

Yes. With HSS and manual on a pop-up flash.

It was solved with K-5II - it is very accurate.

It was behaving strange on original K-5, but after one of the last firmware updates it is pretty good.

And of course there are areas to improve (groups, remote power adjustments in manual mode, x-sync), but it is usable already and it looks like it is much better with K-3

So the built-in pop-up flash can wirelessly trigger a flash with HSS model now? That is a great upgrade if true! Right now I have to mount the flash on the camera for HSS, or use another flash on camera to trigger a wireless flash for HSS.

An dI hope to see an electricity signal wireless control on camera. Sometime, particularly outdoor, light trigger is not very reliable.

Yes - didn't you read the specs?

Buy a radio trigger. You can even buy the one which works as a radio link transferring light signals, so you can use the P-TTL.

I came across this on Ken Rockwell's review of the Nikon D600 whilst surfing for info about the D600 sensor oil and dust I saw mentioned on PF.

1/200 Flash Sync

No big deal, 1/200 is the same as 1/250 only a third of a stop different than Nikon's hottest D3 and D4 pro cameras, and the same as the Canon 5D Mark III. (1/250 is available in an FP mode on the D600.)

No one makes DSLRs with 1/500 sync anymore. What happened is that the older DSLRs used hybrid electronic shutters that let them sync perfectly up to their top shutter speed (1/16,000 on the D1, D1H and D1X), and this was limited to 1/500 with dedicated strobes as not to lose any light. You could go straight to top speed with a non-dedicated flash in manual modes.

When resolutions grew above about 10 MP, the electronic shutters went away, so we're back to being limited by the mechanical focal plane shutter.

No big deal; 1/200 is the same as 1/250 as far as trying to get enough light on the subject is concerned. If I need 1/4,000 sync, I'll shoot my D70 or D40 or my D1 at 1/16,000!
Maybe 1/180th isn't as bad as we are led to believe.

It is a limit if you want to use a radio trigger or any flash does not support HSS model. But I know 240 doesn't help too much. And I will be unreasonable if I want 500.

It's not a matter of 1/180s as much (by the way you can get 1/200s with a simple trick, so Pentax DSLRs are capable of this), as cutting the signal to trigger manual flashes on hot shoe and sync port. If I want to to sync at whatever shutter speed, just let me do this, even at cost of getting the shadow of shutter curtain on my photo.

I saw one like this: Aokatec AK-TTL(TX+RX) Radio Wireless TTL Flash Trigger.
But it does not support HSS.
Can you recommend one?
Anyway, we all agree it is a good feature to have. I wish penatx will have it built-in.

Really? Never checked it personally, but I was sure it did. Of course if you use it with a controller that supports it.

How does an increase in MP's negate the use of higher synch speed?

I don't think there is one then. Then there's the pttl cable option, but sometimes that's not practically possible.

This image is from a Pentax K5IIs with the flash synced @ 1/250th

The unexposed portion of the frame gets considerably larger even with a 1/3rd increase in shutter speed. At a 1/320th sync speed slightly less than half the frame is left unexposed. To allow for higher sync speeds, the shutter unit will need a complete re-design.
