Well, the hotshoe works with the 01 lens perfectly fine. Its not fried or disconnected. I can trigger the flashes without a problem.

But it doesn't work with the 07 lens (which is why its in the title)
Ah, well, you didn't say that it worked with other lenses, so I had no way of knowing that. I don't own that lens nor the Q7 so I'll cease trying to assist.

So other than flash the Q7 / 07 combo works - you can take pictures with it etc.

I was going to ask if focus confirmation was needed to make the flash fire - this fixed focus lens might not provide that and they may have forgotten to skip it when using flash? I'm stretching for ideas here.

I'm using the Q-S1, but yes, other than the hotshoe, the combo seems to work fine.

Do you have the Flash set to "off" in the menu and flash speed slow enough (slower than flash-sync speed)?
Duh, didn't occur to me to set the flash to 'off'.
Works up to 1/250th now.
Thanks Dave

I did an experiment just now with my Q7. I took two pictures consecutively, with the same flash and camera settings, one with an 01 lens and one with an 8.5mm lens in a c-mount adapter.
The picture with the 01 lens set off the flash.
The picture with the adapted lens did not set off the flash.
The manual specifies that a shutter speed of 1/13 or less must be used with a lens other than a 01, 02, or 06 lens, so I had used a speed of 1/4.

Interesting. I don't see any reason why the hotshoe should not fire in that case either.

I began my career as a software engineer when IBM still dominated. One of the "jokes" of the time was the statement " in an IBM manual, the term 'special feature' means 'documented bug' ".

I would apply the term 'special feature' here, but I haven't found it documented anywhere in the Q7 manual. Fortunately for me, I can't think of any reason I would have for using that combination. But, I would still like an explanation for what I'm seeing, if anyone here can come up with it.

What I have found with the Q7:

The only flash that will fire with a non leaf shutter or generically adapted lens is a Pentax flash (and possibly another brand flash that supports PTTL)
Flash setting must be ON for this to occur. Shutter speed is maxed at 1/13 sec

Flashes or triggers that only use the center contact and sides will only fire if a leaf shutter lens or the OEM adapter is installed.
The flash setting must be OFF for this to occur. Shutter speeds up to 1/250 will work.

I have not been able to get single contact triggers or flashes to work with a non leaf shutter lens or adapter in any configuration.

They only call out Pentax flashes in the manual for external use.
Seems this is how it was designed but I can't see a reason why they have done so other than to get you to buy only Pentax flashes.
