I noticed this morning that a lot of popular cameras were listed as out of stock or unavailable at B & H:
The Canon T2i and Panasonic GH2 as listed as Temporarily unavailable
The Sony NEX-VG10 is Temporarily out of sock
The Canon T3i Body only and 18-55mm kit is Temporarily unavailable, though the Canon T3i W/EF-S 18-135mm f/3.5-5.6 IS Lens is listed as available
The Canon 7D body only is Temporarily unavailable, though there are bodies with kit lenses available.
Similarly, the Canon 5D Mark II body only is Temporarily unavailable too, though you can get it with the 24-105mm lens
The Sony NXCAM HXR-NX5U and sister camera the HDR-AX2000 are both Temporarily unavailable.
Finally, the Sony PMW-F3 is listed as Back-ordered.
It's not all bad news though, Amazon does list some of these cameras available as at 11:30am EDT:
Canon EOS Rebel T3i 18 MP CMOS Digital SLR Camera and DIGIC 4 Imaging (Body Only)
Sony NEXVG10 Full HD Interchangeable Lens Camcorder (Black)
The Panasonic GH2 is listed as Usually ships within 1 to 2 months.
