[OM] Re:Extn Tubes with 100 f2.8

[Richard Dale]

Nothing to do with exposure, but I find the lens works very well indeed
with extension tubes, not much distortion especially compared with 50mm
standard. The 50 1.4 (not sure about 1.8) produces a very noticeable
tail-off at the edges, the more extensions you put on the worse it gets.
A very old OM brochure does state that the 100 2.8 has close focus
correction, though the later ones do not.
Hope this helps
Richard
