@Ronken, you are absolutely right. It is very steep learning curve and require a lot of patience.
I was planning on buying MP-E 60 but end up having this setup, which giving me quite promising result given that i can understand light.
@shierwin, you are right.
You will need
1- Extension tubes. (175$ kenko set from ebay, around 200$ from cathey).
2- Reverse ring (around 5$ from ebay, maybe 10+$ from peninsula plaza?)
3- 28mm prime lens with Aperture control (check this video, really some thing [video=youtube_share;wqRn3at0H60]http://youtu.be/wqRn3at0H60[/video]) (<100$)
4- Flash with softbox (i order my softbox today @ 6$SGD from ebay).
5- Flash bracket (trying to get one, don't know if can get a cheapo deal or not).
175 + 5 + 100 = 280SGD
In contrast if you get MP-E 60mm it is around 999USD from B&H + 48.46USD UPS charge= (exchange rate 1.2136) 1271.2 SGD + 7% GST (182) = 1452SGD.
280SGD Vs 1,452SGD
All figures are rough estimate.
