It looks like you're setting a challenge now Philip, to start to explore more the use of flash, despite the apparent limitations of the K70 !

One thing I have discovered Nigel during my brief explorations is as I mentioned earlier - in manual flash mode the built-in flash power on the K-70 can be controlled down to 1/128, i.e. down 7 stops. At that level there is still enough of a flash to trigger the off-camera Yongnuo flash. However, as I usually use zooms or limited lenses that don't open wider than f/2.8, that level of camera flash will have little effect in lighting the subject, or alternatively its power could be increased to balance the light from the off-camera flash as required.

Yes, It's a way of doing it given the limitations', and allows you to take advantage of the Yongnuo's optical slave mode. A lot of peoples flash work is exactly about getting results from what you have available, so a bit of experimentation is always a positive thing.

So I went on youtube to see if there is anything about Pentax flash that I can post up here.

Seems like he recently made a video about it.


I notice in this video, he is using a Cactus with the 360.

It looks like with the Cactus you can use flash on your M43 system


cheers!

True.....but it's double the cost of the K-70!

Despite all the debate about where in the camera range the new KP falls, in many respects, and now also the wireless flash functioning (where did you discover that info?), into the higher end 'semi-pro' / enthusiast category I think ..... Another defining aspect that supports that categorisation I believe is the lack of Scene Modes on the main mode dial. If you're right the inclusion of wireless flash functions will be much appreciated I'm sure.

There you are Philip, all you need is a nice new Pentax AF-540FGZ, and you've got another reason to upgrade from the K70 !

From:

Flash Modes


Auto Flash Discharge (Scene Analyze Auto), Auto Flash + Red-eye Reduction (Scene Analyze Auto) Flash On, Flash On+ Red-eye Reduction, Slow-speed Sync, Trailing Curtain Sync, Manual Flash Discharge (Full-1/128), Wireless (Controller)


It looks promising

Yes...nice compromise on Ricoh's part. Controller is better than nothing and is probably more appropriate than Controller/Master given the low guide number of the flash on the KP.

Hmmm, seems odd to offer only 'control' mode, not 'master' .... Could they just be using the term 'controller' to mean both options? That is how the other built-in flashes have always worked, as far as I know .....

If a manual is available yet we should be able to settle it.

Wow! Only 6 can hardly be useful for anything but controlling an external flash.

Well, if at ISO 200, that's f4 at three metres.

Off by a stop. It's listed as "GN: approx. 6.0 (ISO100/m)". At f/4, iso 100 you're good out to 6/4=1.5m, you need iso 400 to double the effective range to 3m.

I'm also curious about the low guide number. I had thought 11 to 13 (iso100/m) was pretty standard for pentax dslrs (not counting the ones with GN 0). Makes you think it uses different components from the k-70. I wouldn't rule out the possibility of a typo or translation error somewhere.

edit- I just saw a picture of the flash in the up position here: Features4 | PENTAX KP | RICOH IMAGING. The business part looks tiny and like it fits into a little tiny indent.

Or perhaps with the super duper new sensor they just think we should shoot the flash images at high ISOs !

Yes, you're quite right, Brian.

And GN 6 is point-and-shoot strength.
