Default O-shape dual flash bracket and 2 new (cheap) flashes

A while back I told you about my macro setup with two holga flashes connected to the front of the lens fired with a remote cactus trigger, and that I wasn't really happy with those flashes and the way everything freely rotates around the lens.

This week I got my O-ring bracket and the two (yinyan BY-18) flashes and have been trying them out.

First the O-shape, twin flash bracket.



Its a strong as it looks, more than strong enoug for two mini flashes only the ring does not lock solidly.
But that has been corrected by putting some rubber where two pieces of metal connect.
The screw to mount it on the camera is a bit small (changed that to).

Second the two mini flashes (from YinYan SB-18)



I had to small hoya flashes but they didn't recycle fast enough and depending on the loading time gave any range of light.
Also they didn't lock down on the hotshoe (dropped off sometimes), and the battery door was broken the first day.

These 'having two instead of one battery' recycle much faster (3sec), and their output doesn't go all over the place, can be locked on the hotshoe, have a descent (better than descent - would love to have this on my sigma flash) battery door.

Only their angle of lighting is less and I'm now trying out how they can be better diffused.
(last try with two paper bounce cards gave the best results)

So far so good what about the results ...

K20d + Kiron105 + tamron tc1.4

#1 - first shot - (during a break at work) - it was just raining to hard to continue

1/90sec - f8 - iso100

#2 - later that day at work everybody already left but I just had to try again - a hoya I just found

1/90sec - f9.5 - iso140

#3 - even later that evening (at home)

1/90sec - f9.5 - iso200

#4 - even later that evening (at home)

1/90sec - f9.5 - iso200

Next day.

#5 - small soldier beetle

1/125sec - f8 - iso280

#6 - a funnel spider - hiding

1/90sec - f8 - iso280

#7 - a funnel spider - checking out that bright light

1/90sec - f8 - iso280

I've started using the led ring light I've got extra mounted on the lens to give me a better look for focussing.
I'll post a shot of the complete setup as soon as I'm 90% happy with the way the flashes are diffused.

Cheers

Ronny

Nice one!

Been looking at one of these brackets for a while, just wasn't sure those cheap flashes would be any good or give consistent results when used in tandem.

Looking forward to a shot of the whole thing in action, sounds like you might have sold me on them!

That looks like a great set-up for macro Ronny !

Results seem to be very good (is there just a bit of vignetting from the flash coverage on red flower or is it just shadows from the petals undulations ?). I'm not sure about the O ring bracket but I can easily pick up the Yin Yan's here and this definitely looks like an inexpensive solution. I'm sure I couldn't have taken half of those shots at all because it would be down to 1/20, 1/10 or lower without the flash.

As far as I have those flashes now for a few days they are working great.
Only it's always full power so you sometimes have to diffuse them.

I'll post a shot of the setup this weekend, now I'm trying my best to look like I'm working

The vignetting is probably just shadow, or a bad sitting diffuser, those shots where before I cut me a bounce card.

Still have to check how they will preform but I'll post the results as soon as I can.

Nice results Ronni!
Looks like you found a good low cost method for lighting up your macros.
You're a man after my own heart. I'm always trying ways to beat the
high dollar gizmoes with something better and cheaper.

I hear you GW!

As soon as I saw that soldier beetle shot I was reaching for the credit card, that shot is just perfect!

Whatever works. Yankee ingenuity across the pond?

That funnel spider is a lousy housekeeper, dumping his trash at the front door! Great shot.

LOL!

Don't worry, I have 2 cards already, one already fully paid off, hopefully those remote flashes won't cost more than the 2,000 credit limit on it!

One thing I noticed though, the flashes you use are "high voltage" but the triggers you mentioned state they won't work with "high voltage" have you tested the trigger voltages for the flashes? there is a separate trigger system designed for "high voltage"
