Is it possible to capture the startling macro snaps that too without buying particular macro lens? Yeah, it is, Flickr user Rautiocination constructed one such, using a couple of old lenses and $9 worth of parts from eBay.

an ungodly abomination, a EF 90-300 mm lens which is male to male filter coupled to a EF-S 18-55 lens ...potential magnification is around 300 / 18 = ~16x (not taking into account non-full frame sensor, for which i am not sure how it would affect the result in the end)! granted at this mag the lens would be well over a foot long and need the subject to almost be almost _in_ the lens...total cost for me: $9 adaptor from e-bay (as i already had the lenses)
Just look at these subsequent results.
Thanks: Rautiocination
