Here are a few results i took with this setup .
Forget about the quality of the shots for now , and please look at the exif .
As can been seen from the exif using a f/14 wont cut it since the flash is to powerfull .
Another thing to considder is exposure .
In some of the shots you see a shadow at the bottom of the pictures , these shots were taken with a 1/320 sec exposure .
So the flash is a bit too slow fot this exposure .
Using a 1/250 sec with a f/32 will make it work .
I suggest using some difuse material to cut off some of the flash light if using a faster diafragm .
Coffe filter material seems like a good idea .
