I've got a 35mm F1.8 and also have my 18-55mm kit lens.
That's the thing. I have no clue what lens is best suited for this. I would think a macro lens or at the very least some extension tubes on normal lenses.
well I used my 18-55mm canon and it has a macro on it but thats on the 55mm side and I used mine on the 18mm side . Would u show some pics
of what u already done
Its hard to say I think the 18-55mm is fine even if it doesnt have macro.
This is what I do is
1. A take milk to start with in a flat bowl
2. Put my camera on a tripod with and use the 18mm side of the lens
3. Use a pen place its point where u will drop the droplet. Then focus your lens on that point( I use live view mode)
4. Switch off the most of the lights and use the on board flash and just take a normal pick with the smallest f/stop and shutter speed of 1/200 ( place must be really dark but not to dark u still need to see what u doing)
5. adjust the shutter and flash till u get the right exposure on the milk
6. now put your camera on cont shooting for say about 10sec or 5 for how ever long your flash can fire before it times out
7. push the button and start droping it in the milk( I use colored milk with a driper) where u center it with focus on the pen
After that look at the shots. U should get some good shots cause your shooting in a dark room and only lightning up the droplet for a few 1/1000 of a sec
