did anybody try it?.........
...... did it work?
....... did it work well........??
on legality ........
I'm not sure if it is illegal to use them as opposed to sell them.......
it might just be iliegal to sell them - because in kids hands they can pose a nuisance.....
for a legitimate application like camera focussing it might be ok.....
on dangerous....
I'll ask my son how dangerous they are ...... he did an astrophysics degree and studied lasers, but he generally says everything's dangerous.......!!.
this particular one is low powered and not very focused... arguably it's more like a tight focused mini torch
I suspect there is more power/danger in a high powered flash -
but I'm not advocating it as alright for shining in anybodies eyes....
obviously thats to be avoided....

I have used a Maglight Solitaire for such situations for many
months now with a high success rate. It can be fiddly handling the
camera, with external flash attached - due to the whole balance
being thrown out - and the little torch but it works fine around
90% of the time and, with fully charged batteries, the light gives
a throw of up to 4 metres.
Adjusting the beam to a fine point provides adequate contrast and
illumination for the 6900z to autofocus and manual focus is easy.

--If anyone wants to get really hyper about this - and I really don't
see the need ------
It struck me that a little (illegal) penlight laser pointer that my
son used to have - would have made an ideal AF assist light - it
had a number of different front ends and I even think one had a
pattern of parralell lines ..... it was about the size of one
penlight cell and had a push button on one side - could have easily
been fitted with a mount to go on the flash shoe....
........ can't find the thing when you want it.........!!!

Civil-Smivell...!!
.......humbug.......!!
good reply Ian and good support John.....!!
you guys I think have the 6900 and the 602 might be a little
different -
but I don't have much concern on this front - its a load of
drivell......
I echo Ians technique tips..... good stuff and a good level
head......!!
I have a few extra thoughts......
quoting from the FM....
Specifications
"Focus: Passive-type external AF sensor + CCD-AF sensor"
the 602 has two methods of AF
1 the external sensor and
2 CCD contrast......
I believe 2 is more efficient if the ISO level is higher - but I am
not too sure of that - what I am sure of is that the EVF becomes
significantly brighter if 800 or 1600 ISO is selected - and this
definitely aids LL focussing......
if using manual focusing an APPROXIMATE focus from the viewfinder
visually is all that is needed because of the large DOF.
I think that it is likely in LL conditions that the CCD AF will be
the only one to work......??
another thought is be careful not to obscure the external AF sensor
which is in the front of the flash housing just behind the focusing
ring and easy to obscure with fingers....
I have heard it said that the AF is more sensitive if called from
QF in MF.....
I doubt this but Ian is right that any motion at the time of
sensing will interfere with locking....It may be that users taking
the trouble to MF are being more careful and get better focus
because of the extra care......
so ...... what does the 602 have for LL photography......
800 & 1600 ISO......
external & CCD AF
manual focus
Manual focus lock & direction indicators.....
Manual focus magnification area for visual focus.
very good low noise levels..
(and he wants to trade it in for a $3 disposable - I'll do that
trade..!!)
......... and if all that fails..........
there's a 2 METER trick.........
that the camera defaults to 2 METERS if the AF cannot lock..
2 METERS is the optimum distance for flash portraits.... and will
give a wide DOF.....
so don't forget if all else fails use the 2 METER trick.........
............ NOT 2 feet..........!!!
