Hello guys,
that's what these forums are good for - you always learn something new! I must confess that I do not know othe camera in-depth; I bought it for my wife so that she is not bored while I hang around taking photos with my analog Nikonos RS.
Anyhow, I played around with supermacro and slave strobe. My opinion, just as Gary wrote, it will be very (or even too) complicated to use under water (at least for me and my wife)in terms of correct exposure and of strobe placement. I am strict k.i.s.s. guy (as soon as iIget under water, above... well read on) .
Okay this now strays away from the originalquestion (can you use a strobe in super macro?): Why not use a close-up lens instead??? You can either buy the expensive ones from Inon, Olympus etc., or you can do your first tests the cheap way: Try to buy a threaded +10 diopter from ebay (plus, if necessary,a step-up ring if you find a diopter larger than 46mm). Costs almost nothing, less than 10EUR if you take your time to look around!
Last year my wife took some photos with her old mju/Stylus500 this way. (Not with a +10,but with a combined +4 and +2 - but this is not enough,as we found out, under water you "loose" some of the magnification.)
Same for wide angle, on ebay we found a Sea&Sea 16mm lens with a 58mm thread - this one is originally for the Nikonos 35mm lens. With a step-up-ring 46-58mm we now have a real wide lens for 20 EUR! And with very good optical quality. Vignetting is not a problem (at least with the mju500), otherwise just zoom in a small amount.
Our latest purchase (also from ebay,as you may guess now) is a Sea&Sea adaptor ring 67mm to Sea&Sea bayonet. So with another step-up-ring 46-67mm we now can use Sea&Sea macro lenses, which were originally made for the Motomarine II. We bought the 1:2 lens,and the whole setup cost us less than 30EUR. I did not have the opportunity to test it other than in our bathtub, but it seems promising. If the focus distance will be too short for good strobe lightning we will just buy a Sea&Sea 1:3 lens and give it a try.
Regards,
Joerg
