Caught a bit of the election coverage on Sky News Australia's overnights and there's some really nice cinematography in use with the prerecorded packages. Can see they're using an expensive looking DSLR on a mount, giving constituent street interviews the same visual feel as the In The Margins promos. Really nice. They mightn't be so creative with studio presentation these days but it's good to see them experimenting in this area.
Suspect it is a cost-saving measure. DSLRs are going to be cheaper than a decent ENG camera like a Sony PMW500, and probably less than a low-cost VJ camera like the JVC GY-HM650. The difference is that the DSLR, whilst giving a nice cinema-look (shallow DoF etc.), probably won't meet EBU (not sure there is an equivalent in Aus) tier standards at even 2J, which means that it may be adding artefacts that hammer encoding downstream. DSLRs are in use by UK broadcasters, but you need a good practical reason to use them, such as being able to pose as a tourist (and not just an "I like the look" one)
The quality may possibly not be an issue for Sky Aus as they are SD ?
Of course they could be using something like a Canon C300 - which gives DSLR-type pictures, but with a broadcast quality backend that meets better than Tier 2J. (2J is the 'not quite good enough for 2, but OK for news' level) But it isn't a dirt-cheap camera like DSLRs are (in broadcast terms)
