Just posted an analysis who well Live View AF (contrast detection) works with the Sigma 150-600 contemporary lens. There so seen to be some issues at 600mm, especially when a TC is attached to the lens. Normal phase sensitive AF is fine, but focus accuracy should be checked when using Live View AF with TCs.

Under some conditiosn it seems that contrast detection AF in live view mode may front or back focus

Offer expires 02/10 or when current (limited) stock runs out. This link gets you $130 off the price you'll see if you just search the Adorama website ($899.95)

Full frame DSLR for $1099? If you're thinking of going full frame there's a great deal right now where you get an EOS 6D plus a large format Canon pro-100 printer and 50 shoots of 19x13 paper for $1099 after rebates. If you don't want the printer it should sell easily for $100. Even if you don't want the printer, the whole deal is still cheaper than just and EOS 6D alone ($1399 after rebate!).
Why? because Canon want you to have the printer and buy ink and paper from them.

There are also a bunch of other DSLR/Lens/Printer deals right how. See  http://www.adorama.com/g/CanonMIR?kbid=12417
for all the current deals.

Just poster a review of the Sigma 150-600/5-6.3 DG OS HSM S (Sports) lens. It's a good lens, designed to withstand outdoor use in all conditions. Excelent mechanical design and good optics at at a price below $1999. There are currently multiple rebates and accessorize offers with the lens for $1799, but those offers may soon expire, so keep that in mind if you are interested in this lens.

Just posted a brief look at the Sigma USB dock, which allows you to update lens firmware and adjust lens parameters such as focus and stabilization via a USB link from a PC or Mac. Note that currently you get a USB dock at no charge when buying a Sigma 150-600 or 120-300 lens (see links in the article), at least if you buy from Adorama. Otherwise it's only $59, which seems like a reasonable price for a very useful device.
