Great prices for a couple of fantastic lens.
The 17-50 makes an ideal everyday lens. I'm moving to it from the Tamron equivalent which recently died. By all reports the Sigma is even sharper.
The 70-200 would make a great telephoto lens. Bulky but it has to be being such a fast lens F2.8.
A bonus is that this seems to be Aussie stock (i.e. not grey) so 2 years local warranty is included. Can confirm it is indeed Aus stock with tax invoice included.
A link to the original 10% of eBay code is given here.
First post so be brutal :)
Seriously though, great prices for these lenses. There's others in the store which seem good value too, these were just the 2 that were on my radar. Not really sure how they can offer them so cheap (even without the 10% eBay deal their prices are still cheaper than the big Hong Kong seller).
The 17-50 is a killer lens.
The 70-200 is an excellent option if you don't want to spend big bucks on the Canon, sharp and distortion free across the range, but keep in mind that it focus breathes like a MF at close distances.
