Hi Folks.

I'd like to invest in a macro lens.

I believe it is better to go for a dedicated macro lens rather than a zoom (+)macro?

Apparently, macro lenses offer 1:1 image size.

My question is, how do photographers achieve the effect of a really detailed, and what looks like a zoomed in shot of the eyes of a fly?

Is this achieved with a 1:1 lens? That wouldn't make sense to me. I would of thought it would be a 5:1, say, or an enlargement by a factor of 5.

What macro lens offers the greatest enlargement of a subject?

I've seen some example photos of the Tamron SP AF90mm F/2.8 (Di) Macro 1:1, and Sigma 50mm f/2.8 EX DG Macro, and these photos don't have the large magnification that I'd like.

Canon offers a zoom macro lens which goes from 1:1 to 5:1 and it's well priced.
Most standard macro's are 1:1.

You can invest in a reverse mounting set up for a 50mm f1.8 (or make the setup yourself). The 50mm f1.8 is very cheap and easy to adapt to the purpose. I mount one onto my 55-200mm kit lens and achieve decent 4:1 ratios.
You don't get much automated control over that kind of set up, so you really have to have the time to get the photo you want.

You can also reverse mount a prime lens to achieve a much greater degree of magnification.

Reverse mounting rings are available cheaply on the web, and Canon users can use the older FD lenses (which are stupidly cheap online). You can also use extension rings to expand option further.

Some info here

Google for lots more info, heaps of examples here on Flikr. There is a guy in Perth who has posted up some great shots, search on Flikr

you can reverse mount any lens (preferably a prime) on any camera because you are only using the filter thread not the mount.
This shot is with a 50mm Pentax off an old film camera reversed on top of a short extension tube.

And this is with a reversed 17mm Tokina Canon Mount reversed on my Pentax camera. The shorter the focal length the more magnification you get when it is reversed (the opposite to when it is the right way round) The downside of the reversing set up is you end up with very close working distances The upside is its incredibly cheap if you have some old lenses ($7 each for the reversing rings $11 for the tubes from ebay).

The really detailed close ups are posiibly achieved with something like the Canon MP-E65 which offers greater magnification. The other thing to consider is macro gives you an incredibly short depth of field, so focus stacking is often used.

something like the Canon MP-E65

That's the lens I was referring to. For the price of it and a decent body, I was considering jumping ship to Canon.

Focus stacking is a pretty neat solution, I've never really been able to get the hang of it, but when it's done right, the results are impressive.
