Thanks for the link. I have never seen these photos before and they do look amazing. I enjoy shooting macro, but I do it mostly with digital cameras (K20d). The smaller sensor size helps to get more DOF. I use MF and film for landscapes and staged shots.
I recently picked up a Zeiss Pancolar 50mm f1.8 lens (got one in mint condition for around 80 euros), which is perfect to get shallow depth of field. I like to use it now for close up shots and play around with the DOF. For true (1:1 magnification) flower and insect macro photos I still prefer a dedicated macro lens.
Here is an example Zeiss photo. Note how smooth the out of focus area is (shot at around f2.8-f3.5 I think) Please accept my apologies for posting a digital photo to analog forum.
