I know many listees will dissagree, since the 200/4 seems prone to vibration
on OM1 or 2 cameras and has a modest MTF compared to the 200/5.
IMHO, the most practical combination could be the proper serial number
180/2.8 + 1.4XA. But you must find either, and 1.4 seems to be rather
expensive. If this doesn´t bother you, and are lucky enough to find the
proper 180/2.8 this is a very good choice: you'll end with a 252mm (near
300mm) at /4. Vibration recommendations regarding the 180/2.8 are the same
as for the /4, but since it's faster lens...
I've used a 200/4 for years and never noticed the vibration issue until I
read about it. I can handheld it if over 1/250. I can take it into my
pocket. I can use it for certain portraits. I think it has good bokeh. I can
couple it to either a 25mm auto tube and get good close ups @f11-16. It can
be coupled to a 65~116 AutoTube with some care because it is relatively
lightweight. Tripod mounted, I've always used the highest possible shutter
speed, in fact I use it tripod mounted as much as possible so as to stop
down @f8. Best of all, you can find the Olympus 2X-A at a sensible cost and
have a rather slow but sharp 400/8. I do mean sharp. I do mean slow, better
get an 1-8 or 1-4 screen, but I've managed good results with the common
1-13. It is appreciated by astrophotogaphers because it lacks of comma
aberration, while the 300/4.5 has some. Now that Mars is fallin down, this
may be an issue of concern....
I know people fond of wildlife photographs prefer the 300/4.5 matched to the
1.4X. and its tripod collar is there and is cute and useful. But can't
remember just now its filter diameter, just in case you need a polarizer. It
would be surely expensive, but it's the same thing with the 180/2.8.
The 300/4.5 doubles the 200/4 weight.
200/5 will be dificult to use w/ the 2X-A, but not impossible. Modern
versions are MC.
Hope this helps.
Fernando.
