This delay is due to the function P-TTL for Pentax, with external flash and/or with internal flash.
Flash in manual mode, creates no problem, but there is not always time to set it,
and I think, will not do a firmware fix for this delay, they would have already done but the hope is the last to die...

Good things to all pentaxian

Well, here is a very encouraging note. Got the old Sunpak 383 Super Auto flash today (KEH good will gesture on the module-less 444D exchange) - and the flash is fantastic. Small flash with big output and wide light for good dispersion, fast recycle; great with the Lumi 80-20 system. Obviously, no trigger delay on the hotshoe. Best of all, stick a small optical slave on the Sunpak, dial in the Manual Discharge setting anywhere from Full to 1/128th for the on-board (add a Demb to soften) - and you have a lot of flexibility and simplicity with consistent multi-flash. While it isn't quite as flexible as radio trigger systems, you really can travel light and not have to worry about excess connections, excess batteries, and can avoid a lot of fiddling. Best of all, no pre-flash needed.

Feeling much better about the K-3 flash situation now.

Fortunately, we are human, and we can also adapt to delays of more advanced technology such as learning to use a Pentax AF-360FGZ that I find it perfect in manual mode, or the Pentax AF 400FTZ with swivel and extendable head. I wish you good job with the Sunpak 383, you wrote that he is old? It would be well informed on the output current ,as several old flash have a return current very strong ,and can damage the camera . Have a nice evening

Actually the issue is voltage, not current. It comes in under 7 volts - very safe. By the 1980s, most flashes were designed with low trigger voltage.

Happy 2015, guys!
I am sorry that this flash delay issue has not been solved entirely!

Is there any Pentaxian(currently owning both K-3 and K-5ii/s) can confirm that
this flash delay issue is introduced by K-3, but K-5ii is free from this?
Thank you in advance!!

(My K5ii doesn't work in P-TTL with the external flash and its a known issue.)
Dear gbeaton, could you please elaborate the flash problem with your K-5ii?
Do you mean the exposure using P-TTL not being consistant?

Yes, the entire K-5 series has inconsistent pTTL especially in bounce mode - and Pentax officials have essentially indicated that they don't expect to find a fix. Apparently the lengthy pause hard-wired into the K-3 pTTL is intended to somewhat improve flash consistency. Bottom line, at least you have more options with the K-3 to work around pTTL. Coupling on-board M ratio flash with Auto external flash is easy, and there are various radio triggers available for more complex set-ups (working around pTTL).

In my experience, the K-01, K-30/50/500 processing core got the most out of pTTL - but still far from perfect. For 90% of shooting situations, working around pTTL is a more reliable and consistent way to go.

Tested with K-20 and k-5II , the problem "delay" does not exist...

My experience with pTTL is limited, but I'll take the K-3's delay over the K-5's inconsistent bounce exposure any day.

That said, my Metz 58 seems to do quite well in auto mode.

Amen. I've gotten used to the slight delay although I wish there wasn't one. The exposure consistency is well worth the sacrifice.

Thank you, ScooterMaxi Jim and Frank the Matt
for you input!

I hope the successor of K-3 will fix this.

This is a 100% correct but it may also be useful to mention that the K-5 P-TTL overexposure bug needs a bit of provoking to rear its ugly head.

So much so, that a fix for the overexposure problem has been proclaimed countless times after firmware updates.

Some posters also claim their K-5 II does not have the bug at all.

I'm inclined to believe that all K-5 (II)s have the bug but that not everyone manages to provoke it.

I'm abstaining anyhow as I shoot fully manual only.

I had K-5 IIs and now have K-3. I would take K-5 IIs over K-3 any day when a flashlight is needed. Almost always P-TTL with K-5 IIs was spot on with a bounced speedlight's head.
P-TTL with K-3 is almost unusable to me due to the long delay.

I'll add a bit more as I shoot P-ttl often from a range of Pentax bodies, P-ttl is not faulty or broken though Pentax seem to do their best to implement it badly

My view of various P-ttl implementations

1 Pentax k10d - under exposes badly below average consistency (against ettl etc)
2 Pentax k20d - under exposes average consistency
3 Pentax k7 - tends to over exposure consistency good
4 Pentax KX - good exposure good consistency some Wb issues
5 Pentax K5 - when direct or on body very accurate exposure, consistent and good WB .... When bounced exposure more related to distance than calculated no consistency at all though repeatable if you don't move because it consistent with distance can foibles can be learn't.!!
6 Pentax Q - good exposer good consistency (though one 'bug' flash needs to set 'off' to use external manual flashes/triggers)
7 Pentax K3 - very accurate flash use but considerable delay make flash unusable in any action shooting

in summary the K3 is the best P-ttl camera but also the only one unusable in flash for a considerable chunk of photography in P-ttl

The flash P-TTL delay issue on the K3, and the complete screw-up with P-TTL off camera on the K5 makes me wonder how much testing Pentax do before releasing a new camera. Hundreds of beta-testers are normally let loose on new computer software, picking up most of the egregious errors before it hits the market. Who tests new Pentax cameras? Is it done just in the lab with a standard suite of settings, or are real photographers used out in the field? There are many very competent and trustworthy experienced Pentax shooters on these forums who could be a great beta-testing resource if Ricoh/Pentax were really concerned with getting it right.
