Does P-TTL need a cord though? That can't work wirelessly?
Yes, P-TTL does work wirelessly, but a synch cord is 100% reliable regardless of conditions and acts just like a hot-shoe flash. Infra-red wireless is is poor to useless in bright conditions and finicky at other times (e.g. line of sight, limited range). Radio triggers are reliable but there's a pretty limited choice for Pentax if you want P-TTL and HSS.

Pentax P-TTL wireless is optical, not infrared.

It's quite good outdoors really, even in sunlight, so long as you can turn the control flash head towards the slave sensor and you keep to within 4 or 5 meters.

No it's not, Audiobomber.

Your flash head itself produces a *much* more powerful signal than the IR transmitter in say, your TV remote.

Do you understand?

I shouldn't have said IR flash, I have no experience with that. I do have experience with Pentax wireless flash and it is not reliable in bright conditions. A synch is virtually as reliable as a hotshoe flash.

But you told us all it was better than optical, when you admit you have neither knowledge or experience!

Do you often make such assertions?

No. Do you have a comprehension problem?

I mis-characterized Pentax wireless as IR. Here's what I should have said:

"Optical wireless is is poor to useless in bright conditions and finicky at other times (e.g. line of sight, limited range)."

Got it now?

Exactly. You didn't know what you were talking about, and are now getting stroppy for being called on putting wildly wrong information into this forum, Audiobomber.

Thumb down!

Let's review what happened. I mistakenly called Pentax wireless "infra-red". You objected, I corrected my error. You got snippy, I gave back what I got. Now you won't let it go, which is your typical behaviour.

Here's what I am saying:
1. A flash bracket is a useful tool. The B&H Flash Bracket Buying Guide | B&H Explora
2. For use in a flash bracket, a cord is more reliable and a better solution than optical wireless.

And both technologies have got some fresh new coverage within my new "Flash Guide Supplement", which I hope will help members choose the best option for themselves. Guys, take a look and let me know what you think ..... SUPPLEMENT to the PENTAX FLASH GUIDE - PentaxForums.com

Only when I prompted, you'd have done nothing otherwise, Audiobomber, of that we can be certain.

If I have educated you, the correct phrase is 'Thank you.'

And you *still* have not corrected your error in Post 19.

When are you going to make amends for that?

It's that saying, 'The gift that keeps on giving.'

Of course not. I did not intentionally post misinformation. I immediately corrected my error.

What error? Post 19 says that optical wireless is inferior to infra-red. Do you disagree?

Back to my point: For use in a flash bracket, a cord is more reliable and a better solution than optical wireless. If you disagree, let's hear about it. Otherwise just shut up. I'm not gong to participate in yet another Clackers death spiral.

Did this correction come from a bolt of wisdom, Audiobomber?

You have already admitted in Post 25 that it needed me to point out your false information, Audiobomber. Just put up with the consequences of being wrong.

Yes, I do.

What's your reasoning?

This may sound like heresy, but with a little photoshop skill you can have whatever catchlight you like in your subjects eyes. i have only started dabling with portraiture using flash (mainly dogs) and if I use say a softbox for key light and an umbrella for fill light, I have to edit the eyes anyway to avoid distracting double catchlights. Not much a stretch to remove square catchlights and replace them with wonderful looking round ones !!!
That's a hell of a lot of work...
