hi, is possible to obtain a deeper DOF? mine seems to be thinner thn majority of pics here?
my setup is a 100mm series e thn i took 2 filters and wedged a 5 times magnifying glass in between and taped them up.
you probably tried that already but have you tried bumping up the aperture (ie make the aperture smaller) to increase the DOF?
hehe .. actually first time i heard this approach of creating a close up lens. you should wrap it up in white paper and put a red rubber band over it and create your own 'L' macro lens
