Mark's macro work has been and is good inspiration. But you make it sound as if I bought equipment for the sake of besting him... :-) I think it was around 2006 I started to play with the 645 optics for macro. IIRC, Mike Wilson has a picture of me applying gaffertape to couple two lenses together... But the 645 lenses were otherwise just collecting dust at the time. Actually, the only person to have run film through my 645n in ten years is some guy from Israel, also in 2006. :-) But I digress... My point is that experiments are required to find optics that fit well together for stacking. One can be very positively surprised with results from what one already has lying around!
