Pro 1; great lens, shoots fast, great zoom, IS works perfectly, screen probably best - even if sunny you still see the taken picture.
The Canon PowerShot Pro 1 was released in early 2004.
One of it's unique selling points was that it has a ring around the lens barrel that controlled the zoom, rather than a zoom lever. This mimicked a proper zoom found on mechanically linked zoom lenses.
It also had a neat fold-out-and-flip LCD display. Very handy for taking pictures above peoples' heads in crowds.
My son (that's him below) loves F1. He's started his own YouTube channel and would love it if you could take a look at one or two of his videos.
Or, if it hurts your ears as much as it does mine, pass the link on to someone who'll really appreciate it.
