Question: 2 x Hot Shoe Adapter F and 5P Sync Cord F

I'm trying to conjure up a twin flash system for Macro using the parts I already have.

I have 2 x AF240FT flashes, 2 x Hot Shoe Adapter F, and 2 x 5PSync Cord F. I also have a custom made flexible bracket to hold everything.

I was hoping to use my radio triggers but the receivers can't be mounted to my flash bracket.

Having set the scene, my question is:-
Can I stack 2 x Hot Shoe Adapter F's, one on top of the other and both on top of a modern Pentax DSLR (I have K20D, K-5, K-5 II, and K3 II) and take each of their attached cords to the flashguns.

Given that the adapters with hot shoes on top will activate a flash attached as well as at the end of a cable, in theory it should. Best to try and see. Alternatively get connectors for your trigger mounts as they will give better coordination and settings.

Hello Peter.

It is a tentative yes from me. I have done something similar but with the AF540FGZ flash model.

One thing to bear i mind if you haven't already used the flashes on the K20D / K5 / K3ii, I believe the AF240 is a TTL flash so for the K series DSLRs the flash will operate as a manual flash with the use of the two manual power levels.

Getting older and grumpier. Taking longer to decide which lens to use today.

A collection of manual primes to keep me in touch with the pleasures of doing it old-school.

Thanks Robert and Nigel. I asked the same question on the Facebook group Pentaxians and somebody replied saying they had done it and it works, but only in manual of course. the AF240FT flash has only 2 manual settings, H & L, but I have a flash meter so I should be able to set the camera up to suit. If that doesn't work I have a couple of AF400FTZ flashes I could use that have more manual settings.

I'm setting up a hotch-potch of bits I have laying around doing nothing to show potential macro shooters on a couple of Facebook macro groups I'm on that you don't need the latest top of the line gear or oodles of megapixels to take decent macro shots. I have an old Canon 30D (10Mp I think) + adapter for Pentax lenses, Pentax 50mm and 100mm macro lenses, the Sigma 180mm macro lens, extension tubes, bellows, macro focusing rail, Raynox dioptre plus all the flash stuff I've mentioned. It may be a bit cumbersome to use in the wild but it should make a decent studio macro set up with a light tent etc.

I won't be able to post any images here because of the Canon component but hopefully, a link to my Flickr account will be acceptable.

Time will tell if it all works out. Thanks for your help.

Well, I can confirm that the dual flash/cable/stacked hot-shoe adapter works, but I've given up trying to use the Canon 30D with a Pentax lens, it's way too fiddly stopping up, focus, stop down, take the shot, mainly because the lens is not in the same rotational place as it would be on a Pentax body.

Tomorrow I'll try the K20 D together with tubes + nifty 50, then reversing ring and 28mm.
