I was impress with my previous testing Jul 2010 as show below
Canon MP-E65 + Canon MT-e4 + Wimberley Macro twin bracket
as mentioned previously , the setup were
i. little bulky
ii. difficult to control the position as need to adjust the screws for different magnification
iii. costly (do I mentioned this ?)
but I really need the flash to be backward little bit to have better control of the light (better angle and make bigger light source)... so I am looking at alternative for pass 1month... finally I found a similar accessories to have similar setup as above but
i. 1/10 of the owimberley cost
ii. and better and easier adjustment of angle (without need to losse and tight the scews)
a twin flash clamps ...
so I have similar setup
I may not have time to test this setup this week... preparing to go another jungle for coming weekend. But will definitely share results of this twin flashes setup ASAP to you all ..
