After having read this I decided to take my EOS 5 on holiday with (expired in 2009) Kodak E100G, I exposed 1/2 stop over and I'm really pleased with the results. I've no concerns over using the rest of the box now, they've been kept in the fridge most of the time up until about a year ago.

I bought a 1DS mk2 about 5 years ago, really solid build quality and image quality is excellent at lower ISO settings. Focussing is pretty fast and is hugely customisable in terms of focus point selection and tracking speed. The downside is that newer cameras control noise better at ISO1600 plus and the batteries can be a pain as they seem to loose charge in a couple of days and suffer from the memory effect. Definitely buy some spares.

This is probably another one of the factors that for the large part has no perceptible effect. For me I'll rank it alongside the following we all fret about but are not that important: a few specs of dust in a lens, slight mark on an optic, not using zeiss/Leica lenses, not using MLU with a tripod.

I bought a Yongnuo 568 which is fully comparable with EX580 and will act as Master for my EX430, the problem I've had is that the white balance struggles terribly in mixed lighting such as tungsten. I'm using a 1DS mk2 and I've never had an issue with other flashes, it works fine in manual mode but with looks horrible in TTL although I've manually set white balance and it performs ok I'd have reservations about using it as my primary flash on a job.
