I am looking to get back in to macro photography at minimal expense and am looking for some suggestions on the best way to do this. I have a nice Zuiko 50/3.5 macro lens for OM system, gathering dust along with all my other old OM gear as the cheap point-and-shoot digital has made it difficult to justify the expense of feeding the film SLR. From what I can gather, new macro lenses start at $400+ so I am thinking it might be best to get an entry-level DSLR with basic zoom for everyday use, and use the Zuiko with an adapter for macro use-- is that reasonable? I am also toying with the idea of the same trick with an Olympus PEN (a giant phallic EOS with a little Zuiko 50 on it would look just a bit odd!) but am wondering how well you could manually focus on an LCD screen... Still, this is probably going to be out of reach for me. Is there anything worth looking at on the used market? It seems to me there is very little out there that is much cheaper than the entry level new models.
