Huge sniplets of probably very interesting and factual information that you
probably wanted to read.

If a system has a dial which shows me a mechanical speed available when the
batteries go south during the winter months, and it doesn't work when using
a winder, then of course it's a feature.  How stupid of me to call it a bug
;-)

When will the secondhand OM3Ti prices start to fall do you think?


All the best,
