It seems that the longest macro currently produced for K-mount might
be about 100mm. I've heard mention of a 200mm, and I have an old
manual focus 135 1:2 macro.
Two part question:
What are the options for long focal length macros? How are they
optically? Are there any teleconverters that do well? Or, am I just
better off cropping tighter?
I have the Tamron Adaptall-2 SP 90mm f/2.5 along with the Tamron
Adaptall 2x teleconverter 01F
to give a 180 mm Macro. I usually just keep the KA mount on the 90mm
though,
what with the 135mm equivalent that gives with my K5.
In a similar vein, are there technical reasons for the dearth of long
macro lenses? Or is it just that the market for them is too small for
them to be commercially viable?
