Some decision routes as suggestion - I think the first step might be to decide
between a true macro lens (prime), a prime or a zoom.
2.8/60 MACRO:
Interesting if you do not plan to switch to FF too soon
+ good equiv focal length (roughly 100 in 35mm language)
+ very good IQ
+ very flexible prime lens (for me for landscape, macro, portrait)
+ true macro design, 1:1 reproduction ratio
+ compact
+ moderate price
- f/2.8 as max aperture but ... strong vignetting at standard distances at 2.8!
To be stopped down for landscape to at least f/4
2.8/100 MACRO (w/ or w/o IS):
FF compatible
+ very good IQ (I have 100 without IS)
+ f/2.8 max aperture
+ true macro design, 1:1 reproduction ratio
+ very flexible medium telephoto on APS-C
+ moderate price
o a little longer focal length, depends on your style of portrait photography
- a little bit larger
2.0/100:
FF compatible
+ very good IQ straigth from f/2.0, excellent from f/4.0
+ f/2.0 max aperture
+ very flexible medium telephoto on APS-C
+ very compact, nearly like a standard lens
+ moderate price
o moderate close focus range
o a little longer focal length, depends on your style of portrait photography
o no macro lens, for me a disadvantage, but if you are not interested in macro ...
