Vicki you don't have to purchase a micro lens to do those kinds of shots. Look into buying some extension tubes, they are just metal round rings that keep the lens further from the sensor thus allowing closer shots. They run about $60 I got mine off of amazon. When buying make sure you get the canon one with the electronic sensors. Hollar at me and I will find what you need and try and help you long distance.
Oh, I have two camera first love is my Canon 5D mark2. The only thing I don't like about this camera it is heavy and with a lens weights around 4 lbs. Second camera is a Canon Rebel txi. I am currently teaching my 8 year old granddaughter how to use it.. I have been a professional photographer for the last 15 years, but have had to slow way down when I broke my hip....so when that happened I started designing in April of 2013...that's my story!
I have a Canon Powershot 50 and it is great in good lighting, but indoors not so much. I have to go for a small camera - as opposed to a nice big SLR with a superduper lense which is what I would like - because I can't cope with anything heavy (I have M.E.)
Vicki, I agree that you do not need to spend a lot of money to get a macro lens to get the images you are wanting. Have you ever tried doing scanography for the really detailed items? So much easier to extract, just make sure you don't use the lid and its dark enough above the item to give it depth without background stuff. Here is one that has been done.. http://www.tipsfromthetopfloor.com/w...ent/orchid.jpg

I blessedly have a backlight scanner so I can also o a white background not just black..
Hope you find some things here you would like to play with. I read an article about scanning your yard...it was amazing!
