Well Thereza, you have to differenciate between two types of macro:
- "true macro", which is a lens that goes up to 1:1
magnification. Normally, when Canon or Nikon call lens "macro" it is a true macro, but most of them can't zoom because they're built for superb IQ
- just "macro", a designation that many third-party manufacturers also use for lenses going up to "only" 1:3 or 1:4
magnification*. There are a lot of zooms out there from Sigma e.g. the Sigma AF 70-200mm f/2.8 EX HSM APO DG macro, that qualify for this. You can also find stabilized lenses in this category, like the Sigma 120-400mm OS that I'm currently testing here
. It goes up to 1:4.2 magnification. The IQ of these lenses when used as macros can be so-so.
Now you have to decide
what you really need: flexibility but not so much magnification or fixed focus but 1:1 magnification and superb IQ.
When I see your current lens-collection, Thereza, I'd suggest looking for the Sigma AF 17-70mm f/2.8-4.5 DC macro, which was reviewed here
. I will also give you the wider end starting at 17mm for nice landscape and architecture shots
As to examples from a lens that goes "only" to 1:4: I'll come back later to show you some!
*Third-party manufacturers have also lenses that go up to 1:1 which are simply designated as "macro". So you have to look carefully which kind of macro you get from Sigma, Tamron or Tokina!
