The "Macro Magnification Ratio" is stated to be 1:2. true macro is 1:1. If you are buying for macro work, you will be very disappointed.

OK you spiked my curosity. What kind of chip is that? How would you like to have to put that thing together with you little soldering gun?
But it is a good example of macro. :) :)

I just bought a lot of old chips from ebay
I was lucky to get a Zilog Z80
And this is more than 4x life size

Not by itself it won't. It will only do 1:1, if you want to do 2:1 or more, you'll need a set of extension tubes.

A true macro lens will do 1:1 magnification. Look at the specifications on the lens, the magnification ratio will be there. It will also be a little towards the pricey side.
Check this out:

The shot taken with my 100mm canon had Canon extension tubes added.
Personally I would advise anyone wanting to do real good macro work to invest in a GOOD and NOT a cheap Ebay set of extension tubes.
Even if/when you buy a macro lens later the tubes will never be out of date as they can be used with most lenses.
It's good you asked. "Macro," like "best," seems to be a generic term that manufacturers use to sell products. We have a separate section on UHH for macro photography. Take a look.
Another point to mention, is that true macro lenses are "flat field" lenses. Meaning they are designed to be sharp corner to corner (just like enlarging lenses). Zooms with a "Macro" feature have too many design compromises to be effective macro lenses...
If money is a consideration, make sure you really want to do true MACRO first. Most people think they need macro to take photos of insects, frogs, flowers etc, when what they are really need is a good close up lens. If you want to take photos of the eyes of insects, then you need true macro. The advantage of a good 70-300 "MACRO" lens is that you do not have to get really close to your subject.
I'm curious JR, what was your lighting arrangement? Great macro shot.
