What I'm interested in confirming really, is the apparent good performance of HSS using P-TTL mode with 'a' series lenses. In theory (I thought) any P-TTL operation should not work with 'a' lenses ?? And it certainly doesn't, not consistently, in normal mode (ie not HSS) - but for some mysterious reason, exposures and compensation adjustments in HSS mode seems to work perfectly with 'a' lenses! Great I say It will make for some great wide aperture outdoor portraits

... The beach scene is gorgeous. Colour, compositional balance and above all sharp detail are first class. What's this Samyang 14rmm everyone is raving about? David
Again, great textures, colours and composition - a pleasingly vibrant cocktail. My first reaction on seeing this, though, was to check on-line to see how much a Samyang 14mm costs...
Thanks also for the feedback from you all about the new version of the cliffs shot ... I think I'll keep the original sky but with the tilt and deeper water colour - that seems to be the best balance!

2) Knoll Beach, Studland, northeast facing
This is one of a series of beaches that make up the National Trust area of Studland. Knoll is the nearest to the headland with the Old Harry Rocks, a sheltered bay surrounded by lush ancient forest. Like the rocks it gets the early sun directly.

What's the verdict then ....

Now, we're lucky of course to have a gun that offers P-TTL, TTL, Auto & manual flash modes - wow, we can really have it all ... but I've noticed an interesting thing ... tell me what you think ...
In theory, P-TTL is not compatable as a flash mode for anything other than autofocus lenses - and mostly thats going to be the later DA type, or third party AF equivelants. (It says so in the manual). So, for A-series lenses, if we want auto-flash on a digital SLR then we should use Auto Flash mode ('A' on the LCD display). Here we tell the gun the ISO & aperture. It needs to be told that because the lens / camera does not send the info through the contacts, nor does the flash get distance and focus info - sound right so far?
Now P-TTL just doesn't work with 'a' lenses - in practice I have found that some lenses will activate P-TTL and you can get a decent exposure, but there's very little consistency - try any bounce and you'll soon see!
BUT - and this is the question really ... my tests have shown very consistent and repeatable performance with HSS , in P-TTL mode with 'a' series lenses ... in manual exposure mode with HSS set on the flashgun you set a speed higher than 180th (this then controls the 'background' lighting) and let the flash provide the 'foreground' lighting using HSS. You get the normal P-TTL flash exposure compensation adjustment (+1 / -3 stops), and this seems to work perfectly! I didn't think it should??? But I've had 100% perfect performance and exposures using HSS in P-TTL with 'a' series lenses ....
Is this how it should be , ie designed to be (because the manual doesn't suggest that), or is it a fortunate and explainable freak of the technology that just gives us lucky Pentax people another great choice for flash shooting?

This is a square crop, top brought down and rock moved closer ...
This is a slighter crop, top off a bit and foreground reduced ....
And Joe (redbusa99) processed these for me in silver efex pro - a colour high key and mono high contrast conversion ... thanks Joe, very interesting .... what does everything think ?
Thanks again to you all for the helpful ideas. Late tonight I'll be putting up the 3rd of my Five-in-a-Row
