The term macro is used very loosely and tends to mean any photographic
situation where you get close to the subject.
Real macro photography is where you are working around 1:1 ratio and closer
thereby giving an image on film that is equal in size or larger than the
subject

The macro portion of this lens lets you get really close. Its quite
nice actually, and the bokeh is superb IMO. I think its about 1:4
magnification, more on the digital.

I think 1:4 is right, but it's the same on digital as on film.

Yes, absolutely. Only the AoV is altered.

True. I just looks bigger because we are digitally magnifying it
through the crop factor. But the image projected on the film plane is
obviously the same.

Jens,
Thank you. I know what macro is. I probably didn't formulate my
question clearly enough.
The KMP site does not list this lens as having a macro capability,
Pentax does not call it macro either.
So, I was not sure if the lens had that capability or not,
or why otherwise it had macro
Hope this helps, best regards,
John

Because it is macro only @70mm?
A true Macro lens would be capable of a 1:1 life size or greater (on the film
negative) magnification and be genuine Macro, the 70-210
So, when Tamron or Sigma lenses are called macro, but have a reproduction
ratio of 1:2 (say Tamron 70-300) or 1:2.9 (Sigma 28/1.8,
Tamron 28-300/3.5-5.6), - this is a frivolous use of the term.
They should've been called close focus capable.
Correct?
I guess it would come down to a matter
Macro is one of those devalued terms. I always thought that Macro
photography started at a reproduction ration of about 1:2 to about 2:1.
Higher magnifications become micro photography.

IIRC the true definition of Macro (from an old dictionary/thesaurus) = Larger
Than Life. Times and languages evolve, not always for the better!
