Perfection in spelling ...
Not to pile on quibbles but just to note a typo, for article tweaking:
In noting comparing use w/Canon of this range,
I think that "Sony A 100-400m" gained the Canon's
low end, and this should be "70-400" as given just
above this use.
The article & images have particular worth to me,
who has kin closely associated with that country
--have thus forwarded the URLink ASAP, thanks !
(And in fact I had Ethiopian cuisine (feast!) for T-day.)
