Most of the ones I've used were crap. Exception being the Sanyo Eneloop
batteries -- which actually hold a decent charge for a useful amount of
time. Energizer over-estimate their charge capacities (I've seen reports
of between 10% and 40% depending on testing method), most of the cheap
brands are just plain crap (Uniross especially, Gold Peak are sitting on
the borderline)...
I'm currently using digital camera batteries in a lot of my projects --
basically whatever's cheap at the camera shop (usually Canon NB4L or
NB5L packs). 3.6V 700mAh in a package about the size of a matchbox...
Care-and-feeding is a bit tricky, though Microchip and Benchmarq (erm..
TI) have released a couple of all-in-one Li-ion charger chips which cost
less than ?1 in qty-1 (and about 75p in qty-10) and only need a couple
of external capacitors (and an optional LED) to run.
OT, very... The only Olympus SLRs I really care for
are the PEN-F series
(half frame and beautifully made).
The Pen series were beautiful little cameras... I remember ogling one in
the second-hand section of a local camera shop many moons ago :)
IIRC that;'s an ring-shamed cell around the lens,
and is almost
impossible to replace with anything else
Bingo.
On the otehr hand,
Olympus Trips are not hard to find (I've seen plenty in charity shops),
and they're easy to work on ot make one good one from 2 dead ones.
Fully working ones go for ~?25 on "that auction site". Ones which need a
little attention (usually new light seals) go for a bit less, and the
light-seal kits are a few quid. Not a big deal, but I'd rather like to
play with other kit first. I'd rather like to try medium format or
possibly one of the Leica rangefinder cameras, but the initial cost is a
bit steep.
