Are you referring to the mysterious blue twigs?

I've seen something very similar to this before, also on twigs. This was taken with the Pentax SMC-A 400mm:

Note the similar strange blue on the twigs below the bird.

Can't account for it, though. I wondered if it was reflections from the rather blue bird on wet twigs, but if so it seems very bright.

Can anyone else shed any light?

I'm surprised a veteren (sic) with any camera at all isn't aware that flash guide numbers are always quoted as at ISO 100.

Imperfect though they may be, I think to rant thus at the Pentax manuals is a little unreasonable.

You're right, of course.

It is a bit obscure. What they mean is that you can't get P-TTL with any other external guns other than the two Pentax P-TTL compatible guns. Even that's no longer true, of course, since there are now at least three Sigma P-TTL guns, two Samsung ones, and a Metz, that are all compatible with P-TTL, apart from the AF360 and AF540 FGZs. And there's the baby Pentax P-TTL gun too (AF200? 220?)

I guess I was just lucky - I saw the flash in the viewfinder, thought "huh?", just as you did, then I took a picture looking at the flash unit and saw both flashes. Which made me do a bit more reading.

It's a lot clearer from the flash gun manuals, but I do agree that the K10/100D manuals don't exactly explain what P-TTL really is.

They can indeed.

But you see P-TTL in the manuals, all over the forums, etc...

.. and it never occurs to you to wonder what 'P' stands for?

Lost in the mists of time, barely still present in the racial memory, is a mystical procedure, complex and impenetrable to all but the anointed ones.

Nevertheless, the great spirits on high have come to me in a vision, and declared in other-worldly tones, that I, humble and undeserving though I be, may reveal it to you now.

It is as follows:

Pick up the inspired word, that is the book called "Operating Manual".

Open its hallowed pages (take care lest the light therefrom blind you with its purging brightness).

Read therein and marvel at the wisdom contained. Absorb its great knowledge, hitherto unimagined.


Few have the courage to venture between those covers, yet great enlightenment may come, to those who dare.

You could try Matt's approach to what sounds like the same problem.

No probs. Some of us do it, some of us talk about it...

Likelihood that after it's out, Ben will find fewer things he can post about that let us see the increasing number of Ben-related websites in his signature...

(Hey, we could all sometimes do with taking a lesson in self-publicism from such a master.. )

I paid £700 for mine in January. Wasn't it quite a bit more when it first came out?

It's under £500 now.

I think, if the new one comes out in Jan 2008, I might stick with the K10D for a while at least for nine months or so. Once I've got a couple more lenses, I might feel different!!

Wait and see what DPR says about it, though, eh, George?

Just out of curiosity, given that the new Pentax will probably drop in price quite quickly, as did the other K*Ds this year, how many here would still be early adopters, assuming it's as fab as Ben would have us believe?

I think for me, the next £1k of my photographic budget (which is currently zero ) will be for glass, not a body.
