Right after Nikon announced the new 18-300mm f/3.5-6.3G ED VR lens, Tamron published the price and availability of their 16-300mm f/3.5-6.3 Di II VC PZD MACRO (Model B016) lens for Nikon mount:
Ebay (via Roberts Camera) currently has refurbished Nikon D4 cameras for $4,249 with 180 days warranty and free shipping. This is a pretty good deal considering the original D4 price ($5,996.95) and the current D4s price ($6,496.95). FYI: Amazon still has some new D4 cameras in stock for $6,199.00 (via third party reseller).
The pricing of the new Sigma 50mm f/1.4 DG HSM Art lens will officially be announced tonight, but rumors already point to a $1,000 price tag (maybe even in the $900 range in the US). Shipping will start on April 25 for the Canon version, the Nikon mount will be released later. The first 50mm Art review from SLRgear is very positive - they compared the Sigma lens with the Zeiss Otus and posted their findings here:
"All competing lenses from Canon and Nikon fell short when compared to the resolving power of the 50mm Art. Compared to the mighty Zeiss 55mm ƒ/1.4 Otus, the Sigma holds its own, displaying nearly identical results!"
