Sigma 55-200mm f/4-5.6 DC (Canon fit) lens.
No, it hasn't got image stabilisation.
No, it's not the best telephoto on the market.
But it is only £75 including P&P!
It's small and light and should be fine if you want a cheap and cheerful second lens for a Canon.
No there doesn't appear to be a Nikon one at that price. Or a Sony one. Or a Pentax one. Or an Olympus one. It's for Canons - like wot it says in the title!
