Does pentax hold any macro zoom lens?
Answers: The term "macro zoom" is misleading. They should be labeled "close focusing".
A material macro lens is one specifically designed for sharpness at close focusing distances. It has a "flat field" of focus for photographing stamps or hoary photographs or other flat objects. A true macro lens will also give you a life-size depiction, aka 1:1 reproduction ratio.
The true macro lens is optimized for center to edge sharpness and have minimal light fall-off from center to snake.
A zoom lens with "close focusing" capability has none of the attributes of a true macro lens. A "close focusing" zoom will usually tender you only a 1/4 enthusiasm size image, aka 1:4 reproduction ratio. This is not to vote that you can't take some nice imagery with a "close focusing" zoom because you can.
Pentax offer a full line of zoom lenses near "close focusing".
For their DSLR, they must to be competitive. They USED to long ago when Asahi made the Spotmatic.
The Spotmatic was a great camera beside a lousey screw on lens, but it was a great camera.
Until the AE-1 come long from Canon NEWS photographers who couldn't afford NIKON F's bought Spotmatics and they had a FULL COMPLIMENT of lenses.
Oh, you said ZOOM NO ONE make a MACRO ZOOM. It violates the rules
A MACRO is a flat paddock medium telephoto, normally an 100mm.
ZOOM loses resolution at the edges
So NO
It's fixed lens if anything.
If you are looking for a ZOOM that MACROS get used to SOFT EDGES of late like a set of DIOPTER lenses!
