I would try both the Tamron mirror lens and the M 200/4 coupled with
the A2X converter. Or sell them all and buy an A 400/5.6. The latter is
a very good lens that is frequently available for only $300 or slightly
more. It will focus close enough to allow full frame bird shots. I
don't think any of your other options will do that, and they won't
provide as good a result.

Hi Pentaxians
I do not have a "real" tele lens for bird photography but would like
to try
to get some cormorant shots soon and therefore seek for your advice:
I understand that around 400-600mm on film would be a good start for
such
big birds, do you agree?
Anyway, all I have at the moment is listed below, the flashes I own
will not
be powerful enough for more than 12-20 meters fill flash. I'm prepared
to
invest in a better lens when I like that kind of photography but for a
start:
Which lens or combination would be the best for that task, I know that
all
of the combinations will be rather slow?
a very old Soligor 350mm F 5.6 M42 tele
Tamron SP 70-210 3.5-4 + Tamron SP 1.4
or Tamron SP 2x converter
Pentax M 200mm + Pentax A 2xS converter
Pentax A70-210mm + Pentax A2xS converter
or still the Tamron SP 500/8 mirror lens despite it's shortcomings?
Or just forget about bird photography with that poor equipment?
thanks for any recommendations
greetings
Markus
