Canon EOS 5D/30D/60D/10D/20D/1D/1DS/3/1V
The release is supposed to be two stage (autofocus, release) and lockable for long exposures.
These cost a quid each, but unless I take them out of the packaging the postage in the UK would be £2.80, despite weighing very little they're large enough to be classed as small parcels under the current barmy regulations. Unpacked I'd guess at 90p.
Before I try to flog them on ebay does anyone here want them?
