Great lens guys. Look forward to seeing pix.
Don't eat your words too much, Rawr. There are more than enough unreliable characters out there who will try to keep you on the hook even though they haven't got a hope of satisfying an order. Because I knew this wouldn't be a lens that would be held in stock by retailers in Australia, I checked with CRKennedy first and they confirmed availability and delivery time with Sigma in Japan before I ordered it.
By the way - I have been having fun playing despite the weather, but haven't felt like getting the lens too wet yet, so have confined my playroom to the front veranda. I checked it out with a Kenko 1.5x TC, and although it is slow to focus (it is a rather dull and wet day here), it is just superb with the TC attached - so 750mm here I come. I also did some checks for CA and even with massive glare and backlighting from the sky, there were no obvious defects in the shots I took.
First impressions: (1) heavy - make sure that your spouse works on her muscles so that she can carry it for you
I also suggest a monopod or tripod.
(2) Delightful optically
(3) Works with a 1.5x TC even in low light but slower focus
