Hey guys after the water drop "challenge" brought up by ckiang and simon, i realised that the macro performance of my oly is about average in terms of distance to subject. Oly specs puts it at 20cm. This will mean that I'll be too far away from the water droplet. So my questions then are:

How close did you guys get to the water droplet? 6 cm for the g2? what about the nikon coolpix?

What was the zoom? Full wide, full tele or somewhere in between...

With close up filters will I be able to get the shot of the water droplet? What +? will I need? +4? is it better to buy in a set or will it suffice to buy just a +4? heard that it's about $15
