The previously-delayed Sigma 120-300mm f/2.8 DG OS HSM lens has a newly listed ship date of May 15, 2013. It’s $3600, but it’s a constant f/2.8 throughout the zoom range. It is a beast of a lens. Hit the links below for more details.
I expect both of these models to be in high demand. I sat down with a representative earlier today and he said that while the Blackmagic Pocket Cinema Camera will begin shipping in July, they are expecting a high demand that will lead to a hefty backorder log.
In short, if you want one, pre-order it now.
