AFIAK there is only one macro lens on the market with greater than lifesize (1x) magnification the Canon MP-E65. It's manual focus and you will need macro focusing rails and a tripod to use it at magnification > 1x. List price is $1399 US.
reason I wanted a D SLR was because I liked using my film SLR, but the film and development of said film was way to expensive.
have decided not to get a Digital SLR. I am probable going to get the Canon PowerShot A650 IS.
