How do I know if a second hand unit is good?
So many people are buying second hand equipment from the internet and
contacting us for quotes over the phone. First please ask if it has been
serviced recently (see above), if not cost this in to your purchase price.
Can you see a picture? if so look at the metal areas, are they clean or
corroded? Is the casing dull and lacklustre, has it had a hard life or
is it bright and looked after?
Other than basic visual checks you can only take the sellers word that
all is good. It would not be unreasonable to ask for a money back or exchange
period. So you can check out the functions on land. Most sellers are obviously
reluctant to accept equipment back after a test dive.
Checking equipment is usually simple for housings and accessories. But
flashguns are not as straightforward, triggering the flash with a built
in test switch is fine but if no such switch is present then you have
to resort to the connector pins. Unless you know which pins to short out
flashguns need to be tested with a camera, do not fire while looking
directly into flashguns!. Most flashguns will indicate via an
LED when they are fully charged. Auto flash will normally indicate sufficient
flash when fired at a close subject and flash power variation on TTL setting
is usually sufficient to indicate a working unit. Point the flashgun at
a light wall and see a small flash, direct it at a dark carpet or cover
the camera lens with you hand and you should see a brighter flash.
Cameras need a little more testing, install a dummy film and run through
to check transport in both directions, meter lights should show clearly
and alter according to the ambient conditions, use light and dark areas
to check this. Most cameras will operate with the back open so check the
shutter opens and closes smartly, often slower shutter speeds can be judged
and flash sync speed is best checked by aiming the flashgun into the camera
to fire out of the lens onto a wall, do not look directly into flashguns.
Digital cameras can be tested thoroughly without any guesswork. But all
equipment should be checked with fresh batteries and left overnight to
check for excessive battery usage. A simple battery tester or multimeter
will indicate the battery state before and after testing.
The more technical side of cameras need more sophisticated test equipment
and most repair companies will test equipment at a small charge, but often
a test film shot on land will suffice.
