My bad! It is indeed 1/effective focal length. Where did i get that from??? :embrass:
I'm also learning too haha.

Used the light for a brief period at OSC, it's just 2 LED lights, nothing special. You can use extension tubes to get 2:1 magnifications, use more, go in closer, but got limit la, if not you touch the surface of your subject already lol
It's not a need, it's a matter of choice
Some old timers believed it is more fun to use reverse lens technique.
Cheaper also hahaha
Extension tubes are useful when u need higher magnification, but do note that your working will decrease as u add extension, and light will also fall off. The image quality would not be affected much as there are no glass elements in the tubes. The lens will also not be able to focus to infinity. I've tried the Kenko auto extension tubes : with 26mm extension, the magnification on the Oly 60mm (focused to 1:1) is about 1.74X and the working distance is dramatically reduced (can't remember how close liao). With 10mm and 16mm extensions, the magnifications are about 1.28X and 1.44X respectively.
Alternatively, you may want to try using close up lenses to achieve higher magnification. The quality of the close up lens will in turn affect the image quality. The Raynox line is excellent and affordable. Some close up lenses are highly corrected with 2 elements, like the Canon 500D (not the camera), but are more expensive. The general consensus (from what i've read so far) is that extension tubes are better for shorter focal lengths and close up lenses better for longer focal lengths.
As for reversed lens, the working distance is basically the flange distance the lens is designed for (just think of the film plane as your subject). Nikon has the longest flange distance, i think (tho, not a big difference). You can also couple reversed short focal length lens with a mid telephoto to get even higher magnification. The down side is that the reversed lens will have the rear elements exposed.
Here's a reversed lens coupling comparison :

(Nikon 20mm f2.8 reversed onto Oly 75mm f1.8, about 3.75X, vignettes quite badly, pain to work with)

Btw, the ants are alive and well. =)
Basic setup with FL300 because it can tilt. Home make diffuser. Never use Raynox coz abit too demanding for old man with shaky hands like me.

Nothing to shout about img...acceptable for amateur i guess.

Really like the diffused lighting on your subject. Nice pics!!!

Nice pics! I see a lot of the more experienced shooters using a similar setup, with the diffuser "cupping" the lens. The light is very nicely distributed and soft. Will try it out soon!
As for manual flash control, it is one of those things I've never been really good at. Is there like a rule of thumb that you follow? And then tweak from there?
OMG! Is that a viper?! Fierce! I've only encountered bronzebacks
